IN RE: PERSONALWEB TECHNOLOGIES, LLC, ET AL. PATENT LITIGATION


ORDER GRANTING IN PART AND DENYING IN PART AMAZON'S MOTION FOR SUMMARY JUDGMENT

[Re: ECF 315]

PersonalWeb Technologies LLC and Level 3 Communications, LLC (collectively, "PersonalWeb") allege patent infringement by Amazon.com, Inc. and Amazon Web Services, Inc. (collectively, "Amazon"), and separately by dozens of customers of Amazon, related to the customers' use of Amazon's S3 in connection with downloading files from S3. However, PersonalWeb previously sued Amazon in the Eastern District of Texas ("the Texas Action") for infringement of the same patents by the same product.

Amazon now seeks summary judgment under claim preclusion and the related Kessler doctrine, arguing that PersonalWeb's current lawsuits are barred by the prior action. PersonalWeb counters that claim preclusion does not apply because the instant litigation involves a different feature of S3 than what was accused in the Texas Action. PersonalWeb further argues that the instant litigation does not involve the same parties or their privies and that the previous litigation did not end in a final judgment on the merits.

The Court has considered Amazon's motion for summary judgment of Amazon's declaratory judgment claims and defenses under the claim preclusion and Kessler doctrines, ECF No. 315 ("Mot."), PersonalWeb's opposition, ECF No. 334 ("Opp."), Amazon's reply, ECF No. 350 ("Reply"), and PersonalWeb's sur-reply, ECF No. 354-1 ("Sur-reply").

For the reasons discussed below, Amazon's motion for summary judgment is GRANTED IN PART and DENIED IN PART.

I. BACKGROUND

A. Procedural Background

Beginning in January 2018, PersonalWeb filed numerous lawsuits against Amazon's customers alleging infringement related to their use of Amazon S3. See, e.g., Case No. 18-cv-00149-BLF, ECF No. 1 ¶ 56 ("Defendant has utilized . . . both hardware and software hosted on the Amazon S3 hosting system."). On February 5, 2018, Amazon filed a complaint for declaratory judgment against PersonalWeb, seeking to preclude PersonalWeb's infringement actions against Amazon's customers. ECF No. 18-cv-767-BLF ("Amazon DJ Action"). On February 27, 2018, PersonalWeb filed a motion for transfer and consolidation of pretrial proceedings before the Judicial Panel on Multidistrict Litigation (JPML). MDL No. 2834, Dkt. No. 1. On June 7, 2018, the JPML transferred and assigned to this Court all then-existing cases comprising this MDL. ECF No. 1. Following consolidation of the MDL, additional cases were related or transferred to this Court. See ECF Nos. 23, 42, 44, 158, 160, 311.

On September 26, 2018, this Court ordered that it would proceed with the Amazon DJ Action first. ECF No. 157. At that time, the Court stayed the proceedings in the "customer cases" (any case comprising this MDL other than the Amazon DJ Action). Id. On October 3 and 4, 2018, PersonalWeb filed amended complaints in the customer cases and an amended counterclaim in the Amazon DJ Action. ECF Nos. 175-257.

During the November 2, 2018 Case Management Conference, the Court raised the concern that a verdict against Amazon in the Amazon DJ Action may leave unresolved issues as to the liability of the other defendants in the customer cases. ECF No. 300 at 4. After considering the parties' oral and written statements, the Court designated PersonalWeb v. Twitch, 18-cv-05619-BLF as a representative customer case. Order Re Representative Customer Case, ECF No. 313. PersonalWeb represented to the Court that PersonalWeb would not be able to proceed against the defendants in the other customer cases if it lost against Twitch. Nov. 2, 2018 Case Mgmt. Conf., ECF No. 300 at 6. The Court ordered the stay lifted as to Twitch and ordered that Twitch shall participate in all proceedings. Order Re Representative Customer Case, ECF No. 313 at 3. Accordingly, for purposes of discussing Amazon's motion for summary judgment, the Court relies on PersonalWeb's pleadings against Twitch as representative of PersonalWeb's pleadings in the customer cases. ECF No. 198 ("Twitch Compl."). The Court also refers to the operative complaint in the Amazon DJ Action. See 18-cv-767-BLF, ECF No. 36 ("DJ Compl.").

B. Factual Background Regarding the Technology

1. Patents-In-Suit

In the earliest complaints filed in the customer cases, PersonalWeb alleged infringement of U.S. Patent Nos. 5,978,791 (the "'791 patent"), 6,928,442 (the "'442 patent"), 7,802,310 (the "'310 patent"), 7,945,544 (the "'544 patent"), and 8,099,420 (the "'420 patent") (collectively, "patents-in-suit"). See, e.g., Case No. 18-cv-00149-BLF, ECF No. 1 ¶ 1. All five patents share a specification and each claims priority to a patent filed on April 11, 1995. All of the patents-in-suit have expired, and PersonalWeb's allegations are directed to the time period prior to their expiration. Twitch Compl. ¶ 18. PersonalWeb has dropped the '791 patent from the operative complaints in the customer cases and its counterclaim against Amazon; however, Amazon's FAC in the DJ Action still includes the '791 patent. DJ. Compl. ¶¶ 49-56.

PersonalWeb does not allege infringement of the '544 patent in its counterclaim against Amazon. ECF No. 257. However, Amazon includes the '544 patent in its complaint in the DJ Action. DJ Compl. at 18.

In its complaint, PersonalWeb represents that the patents-in-suit address the problem of how to efficiently name and identify files on a computer network. Twitch Compl. ¶ 11. The patent specification describes the alleged problem that the patents address: "[t]he same [file] name in two different [folders] may refer to different data items, and two different [file] names in the same [folder] may refer to the same data item." '442 Patent at 2:15-17 (available at ECF No. 315-3). PersonalWeb's complaint explains that the patents-in-suit involve using a cryptographic hash function to produce a content-based "True Name" identifier for a file, which "ensure[s] that identical file names refer[] to the same data, and conversely, that different file names refer[] to different data." Twitch Compl. ¶¶ 13, 15-17. For a small file, "[a] True Name is computed using a [hash] function . . . which reduces a data block . . . to a relatively small, fixed size identifier, the True Name of the data block, such that the True Name of the data block is virtually guaranteed to represent the data block B and only data block B." '442 Patent at 12:58-63. Larger files are split into smaller segments. The hash function is applied to each segment, and the resulting values are strung together into an indirect data item. The True Name of this indirect data item is then computed. This becomes the True Name of the larger file. Id. at 14:16-35.

The summary of the invention describes multiple uses for these True Names, including (1) to avoid keeping multiple copies of a given data file, regardless of how files are named; (2) to avoid copying a data file from a remote location when a local copy is already available; (3) to access files by data name without reference to file structures; (4) to maintain consistency in a cache of data items and allow corresponding directories on disconnected computers to be resynchronized with one another; (5) to confirm whether a user has a particular piece of data, regardless of its name; and (6) to verify that data retrieved from a remote location is the intended data. '442 Patent at 3:49-4:37. The patents-in-suit are directed to various specific aspects of this system.

2. Background Regarding Website Functions

In both the Twitch case and Amazon DJ Action, PersonalWeb's infringement allegations involve website cache management. PersonalWeb summarizes the following relevant background regarding website functioning in the Twitch Complaint. Typically, a "webpage base file" includes text, formatting, and links to other web content such as images ("asset files") that make up part of the webpage. Twitch Compl. at ¶ 20. An individual's web browser retrieves a webpage base file from a remote web server, and then the individual's web browser retrieves the referenced asset files from the same or different servers. Id. at ¶ 22. The web browser retrieves a webpage base file or asset file by making a "GET" request to a web server using the Hypertext Transfer Protocol ("HTTP"). Id. The web server may respond to a GET request with a response that includes the requested content and may include other information or instructions. Id. In order to improve the speed of retrieving webpages, a web browser can store a webpage base file and related asset files in a "cache" on the local computer running the browser. Id. at ¶ 24. The web browser can subsequently use cached versions of the webpage or asset file, rather than having to download the same files repeatedly over the Internet. Id.

In addition to these local caches, files are frequently cached on "intermediate" servers. Id. at ¶ 25. When computers communicate on the Internet, they typically do so through a chain of intermediate servers. Like the local cache of a file, an intermediate server can use its cache to deliver files downstream, rather than needing to repeatedly make upstream requests for the same files from the originating server. A webserver can include a "cache-control" header along with an asset file. Id. at ¶ 26. This cache-control header tells downstream intermediate servers and web browsers whether and for how long an asset file may be used, and when the asset file should be refreshed.

Typically, website operators want a browser or intermediate server to use cached files as long as the files have not changed. Id. at ¶¶ 27-28. By using cached files, downstream individuals can load webpages quicker, and a web server saves bandwidth by not delivering the same data repeatedly. However, website operators want a browser or intermediate server to stop using a cached file as soon as the file has changed. Id. The challenge, then, is how to tell a browser when the file has changed such that the browser should download a new version of the file. PersonalWeb alleges that the "True Name" system described by its patents provide a solution to this problem of forcing a browser to download a new version of a file only when the file has changed. That solution is at the heart of the instant litigation.

3. Background Regarding Amazon S3

Amazon's Simple Storage Service (S3) provides web-based storage, which customers access using an Application Programming Interface (API) built according to the HTTP specification. Markle Decl., ECF No. 315-18 ¶¶ 3-4. For example, customers use an HTTP "GET" command to request a file and an HTTP "PUT" command to upload a file. Id. ¶ 4.

S3 generates "ETag" headers for the objects that it stores. Id. ¶ 9. These ETags are essentially extra bits of information that describe a file. For most objects, S3 generates the ETag using the MD5 hash algorithm. This ensures that when a file's contents change, the ETag also changes. Id. Clients can use this ETag functionality for cache management. When a client first retrieves an object from S3, it can store it in a local cache. Id. ¶ 10. If the client subsequently requests the same file, S3 can compare the ETag for the file stored on S3 with the ETag for the same file stored in the client's cache. If the values are the same, "S3 saves time and network bandwidth by responding with a status code" to inform the client that the file has not been modified. Id. ¶ 10. If the ETags do not match, S3 will instruct the client to download the newer version of the file. Id. ¶ 10.

Multipart upload ("MPU") is one feature of S3. Id. ¶ 6. MPU allows an S3 customer to upload a large object, like a video file, as a series of parts. Id. Once all the parts have been uploaded, S3 can assemble them into a single file for storage. Id. MPU generates ETags for each uploaded part as well as for the completed object. Id. ¶ 9. In the MPU context, S3 uses ETags to verify the integrity of the uploaded data.

C. The Complaint in the Texas Action

On December 8, 2011, PersonalWeb sued Amazon and its customer DropBox in the Eastern District of Texas, alleging infringement of eight related patents by Amazon's S3 service. PersonalWeb Techs., LLC v. Amazon.com Inc., No. 6:11-cv-00658 (E.D. Tex. Filed Dec. 8, 2011). As discussed further below, the parties do not contest that the Texas Action involved the same patents as the instant MDL.

In the complaint in the Texas Action, PersonalWeb alleged that Amazon infringed PersonalWeb's patents "by its manufacture, use, sale, importation and/or offer for sale of . . . Amazon Simple Storage Service (S3) and Amazon ElastiCache. Amazon further contributes to and induces others to manufacture, use, sell, import, and/or offer for sale these infringing products and services." FAC Texas Action, ECF No. 315-2 ¶ 20. "For PersonalWeb's claims of indirect infringement, Amazon's end-user customers and consultants are direct infringers of the Patents-in-Suit within the PersonalWeb Patent Field." Id. ¶ 52. Nowhere in the Texas complaint did PersonalWeb discuss or limit its allegations to any specific features of S3.

Pursuant to the parties' stipulation, on June 9, 2014, the court in the Eastern District of Texas Action issued an order of dismissal with prejudice. ECF No. 315-7. The court entered a final judgment dismissing all claims on June 11, 2014. ECF No. 315-8.

D. The Complaints in the Instant Case

PersonalWeb alleges that the instant case revolves specifically around use of ETags for cache management. In its counterclaim against Amazon in the DJ Action, PersonalWeb alleges that S3 uses ETags in response to "conditional" HTTP GET requests to determine whether a customer's browser should reuse its cached data or download a new copy of the data. First Amended Counterclaim ("FACC"), ECF No. 257 ¶¶ 36-38. PersonalWeb alleges that "Amazon thereby reduce[s] the bandwidth and computation required by its S3 web host servers." Id. ¶ 39. Specifically, PersonalWeb alleges that S3 can generate ETags for asset files that customers upload to S3. Id. ¶ 41. In addition, even if the ETag is generated outside of S3, S3 uses the ETag in response to GET requests to determine whether to send a new version of a file to a browser. PersonalWeb's counterclaim alleges infringement of the '442 patent, '310 patent, and '420 patent. Each of these allegations is specifically in relation to S3's cache control features.

The operative complaint in the Twitch case alleges that Twitch "contracted with Amazon to use Amazon's S3 system to store and serve at least some of" Defendant's asset files. Twitch Compl. ¶ 41. The Twitch complaint largely mirrors the counterclaim, including both the background section and the specific infringement allegations. Compare Twitch Compl. ¶¶ 54-60 with FACC, ECF No. 257 ¶¶ 50-56. The Twitch complaint alleges infringement of the three patents included in the Amazon Counterclaim as well as the '544 Patent. Twitch Compl. ¶¶ 71-81.

As an example of Twitch's allegedly infringing conduct, the Twitch complaint includes "an asset file served by S3 with a content-based ETag generated by S3 for that asset file." Twitch Compl. ¶ 51. This example relates to what PersonalWeb labels "Category 3" in the infringement contentions (which are auxiliary to the complaint). As discussed in more detail below with respect to the scope of the summary judgment motion, PersonalWeb accuses four categories of infringing activities by Twitch, of which only Category 3 involves use of S3. The infringement allegations in the Twitch complaint largely ascribe the infringing conduct to Twitch's own origin servers rather than to S3 servers. See, e.g., id. ¶ 57.

In its counterclaim against Amazon, PersonalWeb alleges that the customer defendants directly infringe PersonalWeb's patents "because for each of the elements of the asserted claims, the website defendants either perform or direct and control the vicarious performance of each claimed element." FACC, ECF No. 257 ¶ 23. Alternatively, PersonalWeb alleges direct infringement by Amazon. Id. PersonalWeb sums up the relationship between its complaints against the customer defendants and Amazon as follows:

In some of these actions, inter alia, PersonalWeb alleges that the website defendants infringe certain claims of the True Name patents through their control over and use of certain aspects of Amazon's S3 system to distribute their webpage content so that downstream intermediate caches and end-point browsers only serve/use the latest content authorized by the website defendant. In those actions, PersonalWeb also alleges that the certain website defendants also infringe certain claims of the True Name patents through the combination of their control over and use of these certain aspects of Amazon's S3 system and their control over and use of certain aspects of the website architecture they have used to produce webpages for their websites. FACC, ECF No. 257 ¶ 22.

II. LEGAL STANDARD

"A party is entitled to summary judgment if the 'movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.'" City of Pomona v. SQM N. Am. Corp., 750 F.3d 1036, 1049 (9th Cir. 2014) (quoting Fed. R. Civ. P. 56(a)). The moving party has the burden of establishing that there is no dispute as to any material fact. Celotex Corp. v. Catrett, 477 U.S. 317, 323 (1986). "The court must view the evidence in the light most favorable to the nonmovant and draw all reasonable inferences in the nonmovant's favor." City of Pomona, 750 F.3d at 1049. "[T]he 'mere existence of a scintilla of evidence in support of the plaintiff's position'" is insufficient to defeat a motion for summary judgment. Id. (quoting Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 252 (1986)). "'Where the record taken as a whole could not lead a rational trier of fact to find for the nonmoving party, there is no genuine issue for trial.'" Id. (quoting Matsushita Elec. Indus. Co., Ltd. v. Zenith Radio Corp., 475 U.S. 574, 587 (1986)).

III. DISCUSSION

In its motion for summary judgment, Amazon argues that (1) claim preclusion bars PersonalWeb's claims in this case, and (2) the Kessler doctrine independently bars PersonalWeb's claims. Mot. at 2. For the reasons discussed below, the Court concludes that claim preclusion bars PersonalWeb's claims regarding acts of infringement occurring prior to the final judgment in the Texas Action. The Court concludes that the Kessler doctrine bars PersonalWeb's claims accusing S3 regarding acts of infringement after the final judgment in the Texas Action.

A. Scope of the Motion

As an initial matter, the parties do not dispute that Amazon's motion for summary judgment does not apply to all of PersonalWeb's claims in the Twitch case. PersonalWeb identifies four categories of infringing activities committed by the various customers. See De la Iglesia Declaration, ECF No. 336 ¶ 6; Twitch Infringement Contentions, ECF No. 340-12. Category 1 infringement involves ETags for webpage base files generated by non-S3 web servers. De la Iglesia Decl., ECF No. 336 ¶ 7. Category 2 infringement involves ETags for webpage asset files generated by non-S3 web servers. Id. ¶ 8. Category 3 infringement involves ETags for webpage asset files generated by S3 web servers. Id. ¶ 9. Category 4 infringement involves fingerprints for webpage asset files generated by non-S3 web servers. Id. ¶ 10. At the hearing, Amazon agreed that Amazon's summary judgment motion cannot reach categories 1, 2, and 4. Trans., ECF No. 376 at 24. The parties also do not dispute that Amazon's motion applies to the Declaratory Judgment Action and PersonalWeb's counterclaims against Amazon.

As to Category 3, PersonalWeb alleges that customer infringement in this category involves use of both S3 and CloudFront. Opp. at 3. The parties do not contest that S3 and CloudFront are different products, nor that CloudFront was not accused in the Texas Action; however, Amazon argues that PersonalWeb does not have standing to assert claims related to CloudFront. Reply at 8-10.

PersonalWeb's right to assert the patents-in-suit is apparently governed by the agreement between Kinetech, Inc., the predecessor-in-interest to PersonalWeb, and Digital Island, Inc., the predecessor-in-interest to Level 3 (Kinetech-Digital Island Agreement). ECF No. 363-1, Schedule 1.2. Under that agreement, Level 3 retains the exclusive right to enforce all of the patents in the field of "the infrastructure services of one or more managed global content delivery networks (CDNs) in which a customer's content is served faster, on average, than if served from the customer's origin server or the CDN can typically serve more users than a customer's origin server alone; where at least some customer content on origin servers is replicated to possibly many alternate servers of the CDN, many of said CDN servers being at [Internet Service Provider (ISP)] sites, and where users' requests for origin content are satisfied by directing them to CDN servers." Id.

Although PersonalWeb argues that the Kinetech-Digital Island Agreement does not preclude its right to assert these infringement claims against Amazon's CloudFront product, the Court will not analyze and resolve this issue without input from Level 3. Amazon is free to challenge the inclusion of CloudFront in a separate motion and the Court will expect Level 3 to either join in PersonalWeb's opposition or to file a separate opposition.

Accordingly, for purposes of the instant motion for summary judgment, in the Twitch case the Court will only consider whether claim preclusion applies to PersonalWeb's Category 3 infringement claims based on use of Amazon S3. In its briefing on the motion for summary judgment, PersonalWeb does not argue that its counterclaim against Amazon involves CloudFront. See, e.g., Opp. at 6 (Category 3 involves CloudFront "if the website operator separately pays CloudFront to serve its S3 webpage asset files.") (emphasis added). The Court has reviewed the counterclaim against Amazon and the infringement contentions against Amazon, neither of which appear to mention CloudFront anywhere. ECF Nos. 257, 340-2. Nonetheless, the Court notes that its analysis of claim preclusion in the Amazon DJ Action is limited to S3 and does not reach any allegations based on CloudFront.

B. Claim Preclusion

In a patent infringement case, the Federal Circuit applies the claim preclusion rules of the regional circuit. See Brain Life, LLC v. Elekta Inc., 746 F.3d 1045, 1052 (Fed. Cir. 2014). In the Ninth Circuit, claim preclusion applies where the prior suit: (1) "reached a final judgment on the merits;" (2) "involved identical parties or privies;" and (3) "involved the same claim or cause of action." Mpoyo v. Litton Electro-Optical Sys., 430 F.3d 985, 987 (9th Cir. 2005) (citation omitted). "Whether two claims of infringement constitute the same claim or cause of action is an issue particular to patent law" to which Federal Circuit law applies. Brain Life, LLC, 746 F.3d at 1052.

1. Final Judgment on the Merits

Typically, this element is undisputed. Here, however, PersonalWeb contends that there is no prior final judgment on the merits for purposes of claim preclusion because the contracted stipulation of dismissal in the Texas Action contained express reservations limiting the dismissal's preclusive effect. Opp. at 18.

A dismissal with prejudice "constitutes a final judgment on the merits, and prevents [the plaintiff] from reasserting the same claim in a subsequent action against [the same defendant]." Int'l Union of Operating Eng'rs v. Karr, 994 F.2d 1426, 1429 (9th Cir. 1993). The "parties can draft the terms of a settlement agreement so as to alter the preclusive effect of prior judgments," but the court will not "supply by inference what the parties have failed to expressly provide [in the settlement agreement], especially when that inference would suspend the application of this circuit's principles of res judicata." Id. at 1432-33 (citations omitted).

In the Texas Action, the parties' stipulation of dismissal with prejudice provided:

Now, therefore, it is hereby stipulated, by and among Plaintiffs PersonalWeb Technologies LLC and Level 3 Communications LLC and Defendants Amazon.com, Inc., and Amazon Web Services LLC, that all claims in the above-captioned action shall, in accordance with the concurrently submitted Order of Dismissal, be dismissed with prejudice, that Defendant Amazon.com, Inc. and Amazon Web Services LLC retain the right to challenge validity, infringement, and/or enforceability of the patents-in-suit, via defense or otherwise, in any future proceeding, and that each party shall bear its own costs, expenses and attorneys' fees. ECF No. 340-1.

The stipulation contained no additional language as to the preclusive effect of the dismissal. In the Order of Dismissal with Prejudice, the Texas court specified that Amazon "retain[s] the right to challenge validity, infringement, and/or enforceability of the patents-in-suit via defense or otherwise, in any future suit or proceeding." ECF No. 315-7.

PersonalWeb submits several arguments in opposition. First, PersonalWeb argues that "PersonalWeb retained the right to pursue both the identical as well as additional patent infringement claims pertaining to the TrueName patents against Amazon, which is the only reason Amazon expressly reserved all future, substantive defense rights." Opp. at 18. However, nothing in the stipulation or judgment supports that contention. The stipulation is remarkably and unequivocally one-sided in favor of Amazon. The Court cannot infer that PersonalWeb retained the right to assert future infringement contentions in the absence of express language in the stipulation. See Karr, 924 F.2d at 1432-33; see also Aspex Eyewear, Inc. v. Marchon Eyewear, Inc., 672 F.3d 1335, 1346 (Fed. Cir. 2012) ("the parties' decision to depart from the normal rules of claim preclusion by agreement 'must be express'") (citation omitted)).

Second, at the hearing PersonalWeb argued that at the time of the stipulated dismissal, the parties understood that the dismissal would be construed according to Aspex. Trans., ECF No. 376 at 58, 69. Specifically, PersonalWeb quoted from Aspex: "In order to construe the settlement agreement to reach [new] products that were introduced during the several-month period before the settlement agreement was executed, we would have to conclude that the parties intended to depart from the normal rule that the products at issue in a patent suit are those in existence at the time the suit is filed." 672 F.3d at 1346. Aspex has to do with whether a settlement agreement applies to new products and offers no support to PersonalWeb. In this case, the very same S3 at issue in the Texas Action is again at issue here.

Additionally, in its briefing, PersonalWeb cites declarations of PersonalWeb's counsel and PersonalWeb's Non-Executive Chairman stating that the parties to the Texas Action recognized that PersonalWeb retained the right to assert infringement claims involving S3 in the future. Hadley Decl. & Bermeister Decl., ECF Nos. 335, 337. However, at the hearing, PersonalWeb conceded that it does not intend to argue that these declarations should be interpreted to modify the express language of the stipulated dismissal. Trans., ECF No. 376 at 57-58.

Because PersonalWeb did not reserve any rights in the stipulated dismissal in the Texas Action, the Court finds that the dismissal with prejudice in the Texas Action constitutes a final judgment on the merits for purposes of the claim preclusion analysis in the instant case. See Karr, 994 F.2d at 1429 (dismissal with prejudice constitutes judgment on the merits for purposes of claim preclusion).

2. Identical Parties or Privies

For the reasons discussed below, there appears to be privity between Amazon and its customers. However, the Court does not rely solely on this conclusion to bar PersonalWeb's claims. Even if the Court found no privity between Amazon and its customers with respect to claim preclusion, the Kessler doctrine would fill the gap and thus preclude PersonalWeb's claims. As discussed further below, the Kessler doctrine developed specifically to address customer-manufacturer relationships.

There is no question that the Amazon DJ Action involves the identical parties as the Texas Action. As to the customer cases, Amazon argues that the defendants are in privity with Amazon (1) because their interests as customers are identical to Amazon's own interests in the use of S3, and (2) because Amazon is indemnifying the customer-defendants in the instant actions. Mot. at 8-9.

In the Ninth Circuit, "privity may exist . . . when there is sufficient commonality of interest" between the parties. Tahoe-Sierra Pres. Council, Inc. v. Tahoe Reg'l Planning Agency, 322 F.3d 1064, 1081 (9th Cir. 2003) (internal quotation and citation omitted). Specifically, the Ninth Circuit has concluded that privity exists when the interests of the party in the subsequent action were shared with and adequately represented by the party in the former action. See Shaw v. Hahn, 56 F.3d 1128, 1131-32 (9th Cir. 1995). Moreover, a "lesser degree of privity is required for a new defendant to benefit from claim preclusion than for a plaintiff to bind a new defendant in a later action." Mars Inc. v. Nippon Conlux Kabushiki-Kaisha, 58 F.3d 616, 619 (Fed. Cir. 1995).

As to whether the technology provider-customer relationship creates privity, Amazon relies primarily on another case from this district, Adaptix, Inc. v. Amazon.com, Inc., No. 14-cv-01379-PSG, 2015 WL 4999944 (N.D. Cal. Aug. 21, 2015). There, the court concluded that privity existed between the manufacturers of 4G LTE-compatible devices and the manufacturers' customers because the patent-holder "was fully aware that customers like the John Does existed [and] were in possession of the allegedly infringing devices . . . yet failed to bring claims against them [in the earlier litigation]." Id. at *6. In response, PersonalWeb cites Federal Circuit dicta and a federal practice treatise for the general propositions that a manufacturer "typically is not in privity with a [customer]," and unrelated parties "ordinarily do not have authority to bind each other by litigation with third parties." Transclean Corp. v. Jiffy Lube Int'l, Inc., 474 F.3d 1298, 1306 (Fed. Cir. 2007); 18 Wright et al., Federal Practice & Procedure § 4460 (3d ed. 2018). These authorities state only general propositions that are entirely consistent with this Court's analysis. Transclean Corp. recognizes that privity exists between a manufacturer and customer "when the parties are so closely related and their interests are so nearly identical that it is fair to treat them as the same parties for purposes of determining the preclusive effect of the first judgment." 474 F.3d at 1306 (internal quotations and citation omitted).

The Court agrees with Amazon that the defendants in the customer cases are in privity with Amazon because they share the same interest in the unfettered use of Amazon's web services, and Amazon adequately represented this interest in the Texas Action. See Shaw, 56 F.3d at 1131-32 (privity exists when the interests of the party in the subsequent action were shared with and adequately represented by the party in the former action); see also Mars Inc., 58 F.3d at 619 (a "lesser degree of privity is required for a new defendant to benefit from claim preclusion than for a plaintiff to bind a new defendant in a later action."); Adaptix, 2015 WL 4999944, at *6 (customers are in privity with manufacturer for purposes of determining preclusive effect of previous non-infringement judgment against manufacturer). None of PersonalWeb's arguments displace the fact that in the instant MDL, PersonalWeb sues Amazon's customers for infringement of the same patents related to use of the same technology as PersonalWeb sued Amazon for in the Texas Action. Moreover, PersonalWeb's indirect infringement accusations against "Amazon's end-user customers and defendants" in the Texas Action further support the conclusion that Amazon and its customers share the same interest in the use of S3.

As to the effect of the indemnification agreement, it is undisputed that: (1) Amazon's customer agreement has contained an indemnification provision since June 2017, prior to the date that PersonalWeb filed any of the complaints in the cases comprising this MDL; (2) sometime following PersonalWeb's filing of complaints in the customer cases, Amazon agreed to indemnify its customers; and (3) during the alleged infringement period in this case (January 2012 through December 2016, Opp. at 10), Amazon's customer agreement did not include the indemnification provision.

In support of its argument that privity flows from the indemnity agreement, Amazon cites a case from the Northern District of California with similar facts. See SpeedTrack, Inc. v. Office Depot, Inc., 2014 WL 1813292 (N.D. Cal. May 6, 2014), aff'd, 791 F.3d 1317 (Fed. Cir. 2015). In SpeedTrack, the court found that the defendant-customers were in privity with the supplier of software for managing defendants' websites, and thus the customer-defendants could assert res judicata defensively against SpeedTrack based on the software supplier's previous non-infringement judgment. Id. at *6. The court explained that "[b]ecause [the software supplier] is contractually obligated to indemnify defendants for any losses stemming from a finding of infringement, the court finds that the parties are in privity." Id. The court reasoned that express limitations in the indemnification agreement, including language stating that "[neither] party is the agent or representative of the other party," merely defined the limits of the indemnification agreement and did not defeat the preclusive effect of the indemnification agreement. Id. (emphasis omitted).

For its part, PersonalWeb does not dispute that an indemnification agreement can create privity. Rather, PersonalWeb argues that the indemnification agreement in this case is insufficient to create privity because prior to June 2017 Amazon was not contractually obligated to indemnify its customers for infringement, and the agreement does not apply to claims "arising from infringement by combinations of [Amazon's services], with any other product, service, software, data, content or method." Opp. at 9-10. In addition, PersonalWeb argues that privity is improper because Amazon's customer agreement states that "neither party . . . is an agent of the other for any purpose or has the authority to bind the other." Opp. at 8. PersonalWeb fails to cite any authority in support of its arguments regarding a lack of preclusive effect flowing from the indemnification agreement.

On the specific facts before it, the Court finds that the indemnification agreement provides an additional basis to find that there is privity between Amazon and its customers for the specific "purpose[] of determining the preclusive effect of the first judgment." Transclean Corp., 474 F.3d at 1306. As the court in SpeedTrack explained, PersonalWeb's objections regarding the scope of the indemnification agreement "merely set[] an outer limit on the relationship between [Amazon] and defendants." 2014 WL 1813292, at *6. It is undisputed that Amazon's customer agreement included an indemnification provision prior to PersonalWeb's filing of any of the customer cases, and that Amazon expressly assumed the defense of its customers sometime between when PersonalWeb filed complaints in the customer cases and when Amazon filed its First Amended Complaint in the DJ Action. Thus, Amazon assumed the indemnification of its customers prior to the consolidation of the MDL, and Amazon has not turned away any customer who has asked for indemnification.

3. Same Cause of Action

Federal circuit law applies to the question of whether two actions for patent infringement constitute the same cause of action. See Brain Life, LLC, 746 F.3d at 1052. The Federal Circuit considers two factors to determine whether the same cause of action is present for claim preclusion purposes: (1) "whether the same patents are involved in both suits" and (2) whether "the products or processes are essentially the same" in both suits. Senju Pharm. Co. v. Apotex Inc., 746 F.3d 1344, 1349 (Fed. Cir. 2014) (emphasis omitted). "Accused devices are essentially the same where the differences between them are . . . unrelated to the limitations in the claim of the patent." Acumed LLC v. Stryker Corp., 525 F.3d 1319, 1324 (Fed. Cir. 2008) (internal quotations and citation omitted).

As to the first factor, PersonalWeb asserted infringement of the '791, '442, '310, and '544 patents in the Eastern District of Texas Action. PersonalWeb did not previously assert infringement of the '420 patent. In its briefing, Amazon argues that the '420 patent "makes no difference as a matter of law" because it is a "continuation of the twice-asserted '442 patent, claims priority to the same patent application as [the other patents-in-suit], shares the same specification with the other [patents-in-suit], and is limited by a terminal disclaimer." Mot. at 4. At the hearing, counsel for PersonalWeb stated on the record that PersonalWeb does not contest that the '420 patent alleges the same claims at issue in the Texas Action. Trans., ECF No. 376 at 75. Accordingly, the Court finds that for purposes of claim preclusion, the scope of the '420 patent is essentially the same as the previously asserted '442 patent. See SimpleAir, Inc. v. Google LLC, 884 F.3d 1160, 1167 (Fed. Cir. 2018) ("[W]here different patents are asserted in a first and second suit, a judgment in the first suit will trigger claim preclusion only if the scope of the asserted patent claims in the two suits is essentially the same.").

As to the second factor, it is undisputed that the infringement contentions in Category 3 involve the use of Amazon S3, the same product in dispute in the Texas Action. However, the parties dispute (1) the scope of the contentions in the previous litigation and (2) whether claim preclusion applies to different features of the same product.

a. Scope of the Contentions in the Previous Litigation

PersonalWeb argues that claim preclusion does not apply because "[t]he Texas infringement contentions were very specific to the MPU features of S3, not to S3 in general." Opp. at 11. In particular, PersonalWeb argues that the conditional HTTP GET request used in the cache control feature central to the instant MDL is not used in MPU. Opp. at 5. Amazon argues that the complaint in the Texas Action involved the entire S3 product. Reply at 4. Moreover, Amazon argues that PersonalWeb's infringement contentions in the Texas Action included the same use of GET and ETags that it accuses in the instant litigation, and that PersonalWeb sought discovery related to these commands in the Texas Action. Mot. at 13.

PersonalWeb's argument regarding the scope of the Texas Action is not persuasive. The complaint in the Texas Action alleged that Amazon infringed "by its manufacture, use, sale, importation and/or offer for sale of . . . Amazon Simple Storage Service." Texas Compl., ECF No. 315-2 ¶ 28. The complaint does not discuss any specific features of S3, does not include the words "upload" or "download" anywhere, and does not limit PersonalWeb's allegations to any specific features of S3. This evidence alone is sufficient for this Court to conclude that the allegations in the Texas Action involved all of S3, not just a particular feature. See Mars Inc., 58 F.3d at 619-20 (looking to the prior complaint to determine whether two cases related to the same set of transactions for purposes of claim preclusion).

Moreover, PersonalWeb's enumerated patent claims in the Texas Action included claims directed to downloading. ECF No. 340-2 at 1. PersonalWeb also made discovery requests in the Texas Action including the use of GET operations related to downloading. ECF No. 350-6 (discovery request related to "conditional matching GET Object operation, using an eTag, such as "If-Match" and "If-None-Match."); ECF No. 350-7 at 90:19-23, 91:5-8 (deposition testimony on conditional GET commands). The Court finds that this evidence supports Amazon's argument that the Texas Action included the specific functionality accused in the instant case.

At the hearing, PersonalWeb offered two arguments to get around this evidence. First, PersonalWeb argued that there are disputed issues of material fact as to whether the infringement contentions in the Texas Action included use of the HTTP GET command. Trans., ECF No. 376 at 51. PersonalWeb cited the declaration of Mr. Hadley, who stated that the use of "conditional HTTP GET requests containing ETags . . . was not a part of the Texas Action and PersonalWeb made no contention that such uses infringed any PersonalWeb patent." Hadley Decl., ECF No. 337 ¶ 4. Mr. Hadley explained that "[t]he references to conditional HTTP GET requests in the [Texas] Infringement Contentions" were related to showing that conditional HTTP GET requests are analogous to MPU. Hadley Decl., ECF No. 337 ¶ 4.

The Court finds that Mr. Hadley's declaration does not create a genuine dispute of material fact because the declaration is "uncorroborated and self-serving." Villiarimo v. Aloha Island Air, Inc., 281 F.3d 1054, 1061 (9th Cir. 2002). Mr. Hadley's recollection of the gravamen of the Texas Action does not dispute the plain meaning of the Texas Complaint, infringement contentions, and discovery requests. Viewing the evidence in the light most favorable to PersonalWeb, the evidence shows that the discovery and infringement contentions in the Texas Action primarily involved MPU but also encompassed the HTTP GET (download) command. No reasonable jury could conclude otherwise. See Scott v. Harris, 550 U.S. 372, 380 (2007) ("When opposing parties tell two different stories, one of which is blatantly contradicted by the record, so that no reasonable jury could believe it, a court should not adopt that version of the facts for purposes of ruling on a motion for summary judgment."). Mr. Hadley's posthoc recollection of his litigation strategy is simply insufficient to place this issue in dispute.

Second, PersonalWeb argues that the scope of the Texas Action should be limited to what was included in the infringement contentions, and not the complaint. Trans., ECF No. 376 at 44-45. Even if the Court agreed with PersonalWeb, the Texas infringement contentions included the HTTP GET command, and thus PersonalWeb's argument fails on its own terms. Moreover, the case that PersonalWeb cites does not support its argument. Contrary to PersonalWeb's description, Wowza involved different versions of the same product. See Adobe Sys. Inc. v. Wowza Media Sys., LLC, 72 F. Supp. 3d 989, 995 (N.D. Cal. 2014). During the prior case in Wowza, the court struck Adobe's "RTMP Enhanced" infringement theory because the theory was added to an expert report but was not in the infringement contentions. Id. at 991. In the second case, the court held that the RTMP Enhanced theory was not barred by claim preclusion because the "RTMP Enhanced theory [was] asserted against products released after the filing of the infringement contentions in Wowza I." Id. at 995. Thus, the RTMP Enhanced theory was not barred in Wowza II because it related to new products, not as PersonalWeb would have it because the court limited its claim preclusion analysis to the infringement contentions.

In sum, the Court finds that both the complaint and the infringement contentions in the Texas Action indisputably support the Court's conclusion that the Texas Action asserted infringement against all of S3 and was not limited only to MPU.

b. Different Features of the Same Product

Even if the Texas Action involved all of S3, PersonalWeb argues that claim preclusion does not apply because "the accused features of S3 here and in the Texas Action were completely different." Opp. at 12. PersonalWeb argues that "MPU is priced separately from the downloading and serving features of S3." Opp. at 13. Amazon argues that "multipart upload is a feature of S3, not a separate product, and a feature that uses ETags no less so than single-part upload files." Mot. at 12.

As an initial matter, the Court finds that there is no genuine dispute of material fact as to whether multipart upload is a feature of S3, not a separate product. The declaration that PersonalWeb cites explains that S3 customers are charged for each individual transaction involving uploading or downloading objects and for retaining storage. Markle Decl., ECF No. 341-11 at 97-99, 101. At most, this evidence shows that Amazon charges individual prices for specific transactions within S3, not that MPU is a separate product.

The Court notes that PersonalWeb does not argue that S3 has changed in any way that is meaningful to PersonalWeb's infringement contentions, and Amazon does not argue that the differences between multipart upload and cache control are "unrelated to the limitations in the claim of the patent." Acumed LLC, 525 F.3d at 1324. Accordingly, the issue before the Court is the legal question of whether claim preclusion applies where the later suit involves different features of the same product as the original suit.

Amazon has pointed the Court to a single case involving similar facts. See ViaTech Techs., Inc. v. Microsoft Corp., No. 17-570, 2018 WL 4126522 (D. Del. Aug. 28, 2018). The court there explained:

Plaintiff accused Windows alone of directly infringing the '567 patent in the First Action. Now, reading the Amended Complaint in the manner most favorable to Plaintiff, Plaintiff's direct infringement claim in the Second Action includes not only Windows, but other items, such as media, as well. Plaintiff has not alleged that adding media changes Windows, nor alleged that Windows has changed since the First Action. Given that Plaintiff previously asserted that Windows infringed the '567 patent, Plaintiff cannot once again accuse Windows of infringing the '567 patent, but argue that other items, like media, are necessary for infringement. Likewise, Plaintiff cannot repeatedly assert its patent against different parts of Windows in separate suits, even if one accused part is on the left-hand side of Windows and the other is on the right-hand side, so to speak.

Id. at *3 (internal citations omitted).

ViaTech is consistent with the doctrine of claim splitting. "It is well established that a party may not split a cause of action into separate grounds of recovery and raise the separate grounds in successive lawsuits." Mars Inc., 58 F.3d at 619. "A main purpose behind the rule preventing claim splitting is to protect the defendant from being harassed by repetitive actions based on the same claim." Clements v. Airport Auth. of Washoe Cty., 69 F.3d 321, 328 (9th Cir. 1995) (internal quotation and citation omitted). In the patent infringement context, the Federal Circuit has explained that "claim preclusion bars both claims that were brought as well as those that could have been brought." Brain Life, 746 F.3d at 1053 (emphasis in original).

PersonalWeb cites Young Engineers, Inc. v. U.S. Int'l Trade Comm'n., 721 F.2d 1205, 1316 (Fed. Cir. 1983), which states the unremarkable proposition that "claim preclusion [does not] apply to conduct of a different nature from that involved in the prior litigation." PersonalWeb argues that "[n]one of Amazon's cases suggest that the commercial packaging of different features or aspects of accused devices has any bearing whatsoever on whether they are part of the 'same transaction' for claim preclusion purposes." Opp. at 13.

PersonalWeb's argument is unpersuasive. PersonalWeb fails to cite any cases that support its contention that infringement allegations related to different features of the same product give rise to separate causes of action. The Court finds nothing in the relevant Federal Circuit precedent to support PersonalWeb's argument. See, e.g., Acumed LLC, 525 F.3d at 1324 ("[O]ne of the essential transactional facts giving rise to a patent infringement claim is the structure of the device or devices in issue. . . . Adjudication of infringement is a determination that a thing is made, used or sold without authority under the claim(s) of a valid enforceable patent." (emphasis added) (internal quotations and citations omitted)). The doctrine against claim splitting applies with full force here. Accordingly, the Court concludes that the fact that this suit allegedly involves a different feature of S3 from the Texas Action makes no difference to whether claim preclusion applies.

4. Post-Judgment Claims of Infringement

Having concluded that claim preclusion applies to the instant case, the Court now turns to Amazon's argument that claim preclusion applies "through the expiration of the patents." Mot. at 14. As a fallback, Amazon argues that PersonalWeb's claims are barred at least through the date of final judgment in the Texas Action. Reply at 10. PersonalWeb contends that claim preclusion only applies up to the date of its amended complaint in the Texas Action. Opp. at 15. The Court concludes that claim preclusion bars PersonalWeb's claims through the date of the final judgment in the Texas Action.

Recent Federal Circuit case law is conclusive on this point. In Mentor Graphics Corp. v. EVE-USA, Inc., 851 F.3d 1275, 1301 (Fed. Cir. 2017) the court held that "claim preclusion does not bar a patentee from bringing infringement claims for acts of infringement occurring after the final judgment in a previous case." The court explained that "for products made or sold after the previous actions, it [does] not matter whether the new products [are] essentially the same as the previously accused products. . . . [T]he patentee could not have brought those claims in the prior case." Id. at 1299 (internal quotation and citation omitted); see also Asetek Danmark A/S v. CMI USA Inc., 852 F.3d 1352, 1365 (Fed. Cir. 2017) (claim preclusion does not apply to post-dismissal conduct, "even if all the conduct is alleged to be unlawful for the same reason"); Brain Life, 746 F.3d at 1054 (claim preclusion does not bar infringement claims arising from "acts occurring after final judgment was entered in the first suit").

Amazon argues that there is an intra-circuit split within the Federal Circuit as to whether claim preclusion bars infringement claims arising from acts occurring after the date of the first judgment. Mot. at 14. Amazon argues that, until the Federal Circuit resolves the alleged conflict en banc, Nystrom v. Trex Co., Inc., 580 F.3d 1281 (Fed. Cir. 2009) is the controlling precedent. In Nystrom, the Federal Circuit held that claim preclusion barred the patentee's suit as to products that "reached the market after the filing date of the original . . . complaint." Id. at 1284. However, the Federal Circuit has since clarified that "[a]lthough the Nystrom court characterized its analysis as falling under the general rubric of res judicata or claim preclusion, the principle that the court applied was" that of issue preclusion. Aspex, 672 F.3d at 1343. Accordingly, this Court will follow the Federal Circuit's own interpretation of Nystrom as not conflicting with more recent Federal Circuit precedent directing that claim preclusion only applies to acts of infringement that pre-date the first judgment.

PersonalWeb argues that claim preclusion can only apply up to the date of the amended complaint in the Texas Action because PersonalWeb was not required to assert any cause of action that it acquired during the pendency of the Texas Action, and that any such cause of action is not barred by claim preclusion. Opp. at 16. PersonalWeb submits that Gillig, Aspex, and Dow Chemical support its argument. Opp. at 15; Trans., ECF No. 376 at 38-42. PersonalWeb's argument that it was not required to assert any new cause of action is true as far as it goes, but that does not help PersonalWeb here. As discussed above, this case involves the same cause of action as the Texas Action. The cases that PersonalWeb cites do not say otherwise.

Gillig, which did not involve patent infringement claims, states that "The res judicata doctrine does not apply to new rights acquired during the action which might have been, but which were not, litigated." Gillig v. Nike, Inc., 602 F.3d 1354, 1363 (Fed. Cir. 2010) (citation omitted). Quoting this language, Aspex explains that "[i]n patent cases, this court has applied the general rule that res judicata does not bar the assertion of 'new rights acquired during the action which might have been, but were not, litigated.'" Aspex, 672 F.3d at 1345 (quoting Gilig, 602 F.3d at 1363). In Aspex, the Federal Circuit concluded that claim preclusion does not apply to products that were not in existence at the time of the filing of the prior complaint. See id. Unlike Aspex, the instant case does not involve new products that were not in existence at the time of the filing of the prior complaint. Moreover, Aspex explicitly held that claim preclusion could apply to new products introduced between the filing of the complaint and the judgment in the previous case, if the patentee elected to have those products included in the previous action. See id. Thus, Aspex and Gillig do not support the conclusion that claim preclusion only applies up to the date of the complaint in the prior action.

At the hearing, PersonalWeb specifically directed the Court to the holding in Dow Chemical, Trans., ECF No. 376 at 39, a case it had cited only once in a string cite in its papers, Opp. at 17. In Dow Chemical, the Federal Circuit reiterated that "traditional notions of claim preclusion do not apply when a patentee accuses new acts of infringement, i.e., post-final judgment, in a second suit." Dow Chem. Co. v. Nova Chems. Corp., 803 F.3d 620, 627 (quoting Brain Life, 746 F.3d at 1056) (emphasis added). In the language quoted by counsel for PersonalWeb, the Dow Chemical court applied the general rule on claim preclusion to the specific facts of that case to explain why claim preclusion did not apply from a previous judgment to a period of supplemental damages. Id. ("Here, the bulk of the supplemental damages accrued after the [previous judgment], and it is clear that claim preclusion also does not apply to damages accruing after the filing of the complaint and not the subject of the first judgment."). Aspex and Dow Chemical are both consistent with Federal Circuit precedent instructing that claim preclusion in patent infringement cases applies up to the date of the judgment in the previous case, at least when the same product is involved in both cases.

5. Summary

For the reasons discussed above, the Court finds that claim preclusion applies because the Texas Action ended in a final judgment, involved the same parties or privies, and involved the same cause of action. Claim preclusion applies to PersonalWeb's claims up to the date of the final judgment in the Texas Action.

C. Kessler Doctrine

Amazon contends that the Kessler doctrine bars all of PersonalWeb's S3 claims, "including claims against Amazon customers for conduct occurring after the date of the Texas judgment." Mot. at 15. Amazon argues that the dismissal with prejudice in the Texas Action "created a trade right [under Kessler] that conferred upon Amazon and its customers the status of non-infringers and upon S3 the status of a non-infringing product." Mot. at 17. PersonalWeb argues that Kessler is "rooted in . . . issue preclusion," and accordingly requires that the question of infringement was actually litigated in the prior case. Trans., ECF No. 376 at 65; Opp. at 19. Under issue preclusion rules, PersonalWeb argues that the dismissal with prejudice in the previous case is insufficient to trigger preclusion under the Kessler doctrine. Id. In addition, PersonalWeb argues that Kessler does not apply to the cache-busting feature of S3 because that feature has never been "held to be non-infringing by any court." Opp. at 20. For the reasons discussed below, the Court finds that the Kessler doctrine bars PersonalWeb's post-judgment infringement claims against Amazon and its customers related to use of S3.

At the hearing, Amazon acknowledged that they have not seen a case specifically addressing whether Kessler applies to claims arising prior to the final judgment in the previous case. Trans., ECF No. 376 at 71. Because this Court concludes that claim preclusion bars PersonalWeb's claims against both Amazon and its customers prior to the previous judgment, this Court does not need to consider whether Kessler also applies to that time period.

In Kessler v. Eldred, 206 U.S. 285, 288 (1907), the Supreme Court held that a prior non-infringement judgment conferred upon the manufacturer "the right to manufacture, use, and sell" the adjudged non-infringing product. Accordingly, the Court concluded that "it is Kessler's right that those customers should, in respect of the articles before the court in the previous judgment, be let alone by [the patentee]." Id. at 289. The Federal Circuit has recently affirmed the continued vitality of the Kessler doctrine, explaining that "the Court granted Kessler a limited trade right to continue producing, using, and selling the [adjudged non-infringing product] . . . even when the acts of infringement occurred post-final judgment and even when it was third parties who allegedly engaged in those acts of infringement." Brain Life, 746 F.3d at 1056. The Federal Circuit explained that "[t]he Kessler doctrine fills the gap between [claim preclusion and issue preclusion] doctrines." Id.

The Court finds persuasive the only case that the parties have identified that squarely addresses the applicability of Kessler based on a prior dismissal with prejudice. In Molinaro v. Am. Tel & Tel. Co., 460 F. Supp. 673, 675 (E.D. Penn. 1978), the previous suit was dismissed with prejudice as a sanction for failure to comply with discovery orders. The Molinaro court explained that the "analysis of the applicability of the Kessler doctrine is not altered by the fact that the infringement question in the instant case was not actually litigated in the [prior] suit." Id. at 676. Molinaro is consistent with Federal Circuit precedent, which explains that the Kessler doctrine applies to claims that "could have been brought"—and were necessary not adjudicated—in the prior action. See Brain Life, 746 F.3d at 1059 (method claims were not actually litigated in the prior action and thus were not barred by issue preclusion but were barred by Kessler).

PersonalWeb seeks to distinguish Molinaro on two grounds, neither of which is persuasive. First, PersonalWeb fails to explain how the fact that Molinaro was based on a dismissal entered as a sanction for failure to comply with discovery orders makes any difference to the preclusive effect of the dismissal. Opp. at 19. At the hearing, PersonalWeb argued that a judicial sanction of dismissal should be treated differently than the parties' voluntary stipulation to dismiss the case because of the punitive aspect of the sanction. Trans., ECF No. 376 at 62-63. Other than the emotional appeal of that distinction, PersonalWeb points to no authority or anything rooted in the Kessler doctrine to support its argument.

Second, PersonalWeb's characterization of Molinaro as "a non-controlling 50 year-old district court case," Opp. at 19, is inconsistent with the Federal Circuit's 2015 opinion citing Molinaro approvingly. See Speedtrack, Inc. v. Office Depot, Inc., 791 F.3d 1317, 1326 (2015). Although Speedtrack cited Molinaro for the specific proposition that a customer could invoke the Kessler doctrine, nothing in Speedtrack suggested that the Federal Circuit disagreed with Molinaro as to the preclusive effect of a dismissal with prejudice.

In its briefing and at the hearing, PersonalWeb cited numerous additional cases that it argues require actual adjudication of noninfringement in order for Kessler to apply. Trans., ECF No. 376 at 68; Opp. at 19. As discussed above, neither Brain Life nor Speedtrack supports PersonalWeb's argument. In MGA, Inc. v. General Motors Corp., 827 F.2d 729, 734 (Fed. Cir. 1987), the Federal Circuit applied Kessler as the equivalent of nonmutual defensive issue preclusion. However, nothing in MGA limits Kessler to the issue preclusion context, and Brain Life cites MGA approvingly for its discussion of Kessler. See Brain Life, 746 F.3d at 1056-57. None of the additional cases that PersonalWeb cites support PersonalWeb's argument that Kessler requires actual adjudication of non-infringement. See Mentor Graphics, 851 F.3d at 1301 (Kessler does not apply when previous case ended with grant of a license to the alleged infringer); Foster v. Hallco Mfg. Co., Inc., 947 F.2d 469, 479-80 (Fed. Cir. 1991) (addressing requirements for claim preclusion); Wowza, 72 F. Supp. 3d at 996 (concluding that Kessler did not apply where earlier case was still pending at time that second case was file).

As to PersonalWeb's attempt to limit Kessler to the MPU feature of S3, the Court finds the Brain Life opinion instructive. In the first suit, Brain Life dismissed without prejudice their method claims and pursued only their apparatus claims. The Federal Circuit reasoned that the products in question "have acquired the status of noninfringing products as to the [relevant] patent," and accordingly "all claims that were brought or could have been brought in the first suit" were barred under Kessler in the second suit. Brain Life, 746 F.3d at 1058-59. PersonalWeb fails to identify any authority suggesting that the question of whether this case involves the same product as the prior case should be any different under Kessler than under claim preclusion. Accordingly, this Court concludes that the Kessler doctrine bars PersonalWeb's current suit as to both Amazon and its customers for all claims related to use of S3 after the prior final judgment.

IV. ORDER

For the foregoing reasons, IT IS HEREBY ORDERED that:

1. Amazon's motion for summary judgment is GRANTED with respect to Amazon's DJ Action and PersonalWeb's counterclaim against Amazon. Amazon's motion is GRANTED with respect to the Category 3 allegations involving use of Amazon Simple Storage Service ("S3") in the Twitch case.

2. PersonalWeb is barred by claim preclusion from asserting any claim of infringement in any case based on use or operation of S3 and is barred from asserting any patent infringement claim against Amazon or an Amazon customer in which a feature or operation of S3 is
alleged to infringe any claim of U.S. Patent Nos. 5,978,791, 6,928,442, 7,802,310, 7,945,544, and 8,099,420 (the "patents-in-suit"), up to the date of the final judgment in the Texas Action.

3. PesonalWeb is barred, under the Kessler doctrine, from asserting any claim of infringement in any case based on use or operation of S3 and is barred from asserting any patent infringement claim against Amazon or an Amazon customer in which a feature or operation of S3 is alleged to infringe any claim of the patents-in-suit.

4. Amazon's motion for summary judgment related to CloudFront is DENIED WITHOUT PREJUDICE. Amazon is free to challenge the inclusion of CloudFront in a separate motion. If Amazon files such a motion, the Court will expect Level 3 to either join in PersonalWeb's opposition or to file a separate opposition.

5. Amazon's requested relief to preclude assertion that S3 meets any limitation of any claim of the patents-in-suit is DENIED as beyond the scope of the motion.

6. The Parties shall advise the Court as to which customer cases are fully adjudicated by this Order, and which claims of the remaining cases are fully adjudicated regarding accused S3 no later than April 3, 2019.
Dated: March 13, 2019
