CHEE Appeal2014-001572 Application 13/165,648 Technology Center 1600 Before ROMULO H. DELMENDO, RICHARD M. LEBOVITZ, and RICHARD J. SMITH, Administrative Patent Judges. DELMENDO, Administrative Patent Judge. DECISION ON APPEAL The Appellant1 seeks our review under 35 U.S.C. § 134(a) of a decision of the Primary Examiner to reject claims 1-11 and 14--25. We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM. BACKGROUND The subject matter on appeal relates to a method for sequencing a plurality of different target nucleic acids by a DNA pyrosequencing method that includes using enzymes distributed on a surface of a substrate to detect a 1 The Appellant states that "Illumina, Inc." is the real party in interest (Appeal Brief filed June 28, 2013, hereinafter "App. Br.," 3). Appeal2014-001572 Application 13/165,648 pyrophosphate released during the DNA synthesis reaction (Specification, hereinafter "Spec," Abst.; i-fi-12, 9). Representative claims 1 and 21 are reproduced from pages 38--40 of the Appeal Brief (Claims App.),2 with the key limitations at issue indicated in italicized text, as follows: 1. A method of sequencing a plurality of different target nucleic acids, comprising: (a) providing a first population of micro spheres comprising capture probes; (b) providing target nucleic acids comprising target sequences; ( c) hybridizing said target nucleic acids to said capture probes on said micro spheres; ( d) providing a second population of microspheres comprising at least one bioactive agent selected from sulfonyltransferase enzymes and luciferase enzymes; ( e) distributing said first and said second populations of microspheres in wells on a surface of a substrate, ( f) hybridizing a primer to each of said target nucleic acids, (g) providing a polymerase and a uniform population of nucleotides to said wells, wherein incorporation of a nucleotide complementary to said target sequence is accompanied by release of 13165pyrophosphate; and (h) detecting said pyrophosphate using said sulfonyltransferase or luciferase enzymes, thereby sequencing said plurality of target nucleic acids. 2 On March 20, 2013, the Appellant submitted proposed amendments to the claims after final rejection, but the Examiner denied entry of these amendments as raising an additional written description (new matter) issue (Adv. Act. entered Mar. 20, 2013). The Appellant did not file a petition to seek review of the Examiner's denial. 2 Appeal2014-001572 Application 13/165,648 21. A method of sequencing a plurality of different target nucleic acids, comprising: (a) providing a substrate having a plurality of sites, wherein said sites comprise covalently bound target nucleic acids and covalently bound bioactive agents selected from sulfonyltransferase enzymes and luciferase enzymes; (b) binding at least one primer to said target nucleic acids; ( c) extending said at least one primer in the presence of a polymerase and a population of uniform nucleotides wherein incorporation of a nucleotide complementary to said target sequence is accompanied by release of pyrophosphate; and ( d) detecting the release of the pyrophosphate using the covalently bound bioactive agents, thereby sequencing said target nucleic acids. THE REJECTIONS The Examiner has rejected the claims as follows: I. Claims 1-11 and 14--25 under 35 U.S.C. § 112, i-f 1, as failing to comply with the written description requirement; II. Claims 1---6, 9-11 and 14--25 under 35 U.S.C. § 103(a) as being unpatentable over Margulies et al. ("Margulies")3 and Margulies et al. ("Supplemental Material");4 III.

("Pourmand"). 6 (Examiner's Answer, entered September 17, 2013, hereafter "Ans.," 2-10; Final Office Action entered January 7, 2013, hereinafter "Final Act.," 7- 27.)7 DISCUSSION In arguing for reversal of the rejections, the Appellant argues independent claims 1 and 21 together, focusing on claim 1. Therefore, consistent with 37 C.F.R. § 41.37(c)(l)(iv), we confine our discussion to representative claim 1 and, by rule, our decision on the appeal for claim 1 controls our decision for claims 2-11 and 14--25. A dispositive issue in this appeal is whether Margulies, which published on September 15, 2005, is available as prior art against claim 1, which was amended during examination of the current application (Amendment filed October 18, 2012). For the reasons discussed in more detail below, we find claim 1, which was amended to recite 5 Rosenthal, Andre et al., Genomic walking and sequencing by oligo-cassette mediated polymerase chain reaction, 18 Nucl. Acids Res. 3095-3096 3095- 3096 (1990). 6 Pourmand, Nadar et al., Multiplex Pyrosequencing, 30 Nucl. Acids Res. 1- 5 (2002). 1 In the Answer at page 10, the Examiner withdrew an objection to the Specification amendment, filed October 18, 2012, and a rejection of claims 1-11 and 14-25 under 35 U.S.C. § 112, i-f 1, as failing to comply with the enablement requirement. 4 Appeal2014-001572 Application 13/165,648 "sulfonyltransferase enzymes" and "providing ... a uniform population of nucleotides," fails to comply with the written description requirement of 35 U.S.C. § 112, i-f 1. As a result, under 35 U.S.C. §§ 119(e) and 120, we find that claim 1 is not entitled to any of the earlier filing dates or priority benefits (see Bibliographic Data Sheet) before the publication date of Margulies. See In re Hogan, 559 F.2d 595, 609 (CCPA 1977) ("There has to be a continuous chain of copending applications each of which satisfies requirements of§ 112 with respect to subject matter presently claimed ... There must be continuing disclosure through the chain of applications, without hiatus, to ultimately secure benefit of earliest filing date.'") (internal citations omitted). The Examiner rejected claims 1-11 and 14--25 under 35 U.S.C. § 112, i-f 1, "as failing to comply with the written description requirement" because the Examiner determined that "[t]he claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that . . . the inventor( s ), at the time the application was filed, had possession of the claimed invention" (Ans. 10). Specifically, the Examiner determined that claim 1 includes the following claim limitations, each of which the Examiner determined does not comply with the written description requirement: "sulfonyltransferase enzymes," "least one bioactive agent selected from sulfonyltransferase enzymes and luciferase enzymes," "distributing said first and said second populations of microspheres in wells," and "providing ... a uniform population of nucleotides to said wells" (Final Act., 10). We address each of these limitations separately below. 5 Appeal2014-001572 Application 13/165,648 1. "!Slulfonyltransferase enzymes" limitation With respect to the claim requirement "sulfonyltransferase enzymes," the Examiner has determined that claim 1 reciting this limitation does not comply with the written description because the Specification does not recite the term "sulfonyltransferase enzymes" and "the term does not even exist in the official enzyme nomenclature, as shown in the search results of enzyme database" (Ans. 11-12). In response, the Appellant concedes that "[t]he specification of the present application does not recite 'sulfonyltransferase'," but argues "the specification frequently recites 'sulfurylase' activity" (App. Br. 29) (citing Spec. i-f 5). According to the Appellant, "[t]he terms 'sulfonyl' and 'sulfuryl' each refer to an -S(=0)2- moiety," the Specification specifically requires "the conversion of PPi to ATP by the enzyme sulfurylase," and therefore argues"[ o ]ne of ordinary skill in the art would understand that the moiety being transferred to ATP is the -S(=0)2- moiety synonymously referred to by both 'Sulfonyl' and 'sulfuryl"' (id.). Therefore, the Appellant contends "sulfonyltransferase was sufficiently described by the specification of the pending application" (id.). We have fully considered the Appellant's arguments; however we find the arguments do not reveal a reversible error in the Examiner's conclusion that "sulfonyltransferase enzymes" fails to comply with the written description requirement. As found by the Examiner (Ans. 11 ), and conceded by the Appellant (App. Br. 29), the Specification does not recite or explicitly disclose "sulfonyltransferase enzymes" and therefore the relevant inquiry is whether there is evidence that one ordinary skill in the art would consider the description related to "sulfurylase enzymes" in the Specification sufficient to support "sulfonyltransferase enzymes" See In re Alton 76 F.3d 6 Appeal2014-001572 Application 13/165,648 1168, 1175 (CCPA 1996) (citing In re Wertheim, 541F.2d257 (CCPA 1976) and In re Oetiker, 977 F.2d 1443 (Fed.Cir.1992), stating "[i]f, on the other hand, the specification contains a description of the claimed invention, albeit not in ipsis verb is (in the identical words), then the examiner or Board, in order to meet the burden of proof, must provide reasons why one of ordinary skill in the art would not consider the description sufficient. Once the examiner or Board carries the burden of making out a prima facie case of unpatentability, 'the burden of coming forward with evidence or argument shifts to the applicant'"). Here, the Examiner proffered evidence to suggest term sulfonyltransferase is not recognized in the official enzyme nomenclature. Additionally, the Appellant concedes that "sulfuryl moieties are associated with inorganic chemical bonds, while sulfonyl moieties are associated with organic chemistry" (Reply Brief entered November 18, 2013 hereinafter "Rep. Br.," 5). From reading the Specification, it would be clear that the substrate adenosine 5 '-phosphosulphate comprises the sulfuryl moiety associated with the inorganic chemical bond of the phosphate group. Spec. i-f 38. In view of this distinction and the Examiner's specific findings discussed supra, we find that the record includes sufficient evidence that the "sulfurylase" as described in the Specification is not sufficiently descriptive of the presently claimed "sulfonyltransferase" and thus hold that the claim reciting "sulfonyltransferase enzymes" does not comply with written description requirement as required by 35 U.S.C. § 112 i-f 1. In so holding, we note that Appellant has proffered no factual evidence, besides mere attorney speculation, that rebuts the Examiner's findings and determinations or that would suggest that one of ordinary skill in the art would find the term 7 Appeal2014-001572 Application 13/165,648 "sulfurylase" to be descriptive of "sulfonyltransferase" in compliance with the written description requirement. See In re Scarborough, 500 F.2d 560, 566 (CCPA 1974). 2. "[C]omprising at least one bioactive agent selected from sulfonyltransferase enzymes and luciferase enzymes" limitation With respect to the claim requirement "comprising at least one bioactive agent selected from sulfonyltransferase enzymes and luciferase enzymes," the Examiner, after a thorough review of the specification, determined that the term "bioactive agent" was in the context of "being a probe which binds a target analyte, and the only instance of the bioactive agent as a protein contemplated in the disclosure was an antibody protein target" and there is no connection between "bioactive agent" and "sulfonyltransferase enzymes and luciferase enzymes" as required by the claims (Ans. 16-17). Specifically, the Examiner, citing all the instances that the term "bioactive agent" is used in the disclosure, determined that the disclosure as a whole provides by a "preponderance of evidence that the term 'bioactive agent' was used to describe a probe directly detecting a target molecule" (id. at 16-34). Therefore, the Examiner concluded that the "designation of sulfonyltransferase enzymes and luciferase enzymes as bioactive agents does not have support in either the original disclosure of the instant application or in the material incorporated by reference" (id. at 35). The Appellant responds that the Specification, as amended, recites "[b ]y ... 'bioactive agent' ... as used herein describes any molecule, e.g., protein, oligopeptide, small organic molecule, polysaccharide, polynucleotide, etc. which can be attached to the microspheres of the invention" and then argues the specification additionally discloses "[i]n a 8 Appeal2014-001572 Application 13/165,648 preferred embodiment, the bioactive agents are proteins" (App. Br. 29-30; Rep. Br. 6-7). Additionally, Appellant argues "enzymes" as bioactive agents is fully supported by the specification because that the specification readily describes "a) bioactive agents can be proteins, b) bioactive agents are used to detect target analytes, c) PPi is a molecule targeted for detection, and d) sulfurylase and luciferase can detect PPi" (Rep. Br. 8). We have thoroughly reviewed the Examiner's review of the disclosure; however, we agree with Appellant that the concept of a "bioactive agent" in connection with the disclosed "enzymes" is sufficiently supported by the disclosure to comply with 35 U.S.C. § 112 i-f 1. As persuasively argued by the Appellant (Rep. Br. 6), the Specification, when including the incorporated subject matter, defines the term "bioactive agent" to describe "any molecule, e.g., protein, oligopeptide, small organic molecule, polysaccharide, polynucleotide, etc. which can be attached to the microspheres" (Amendment to Specification, entered October 18, 2012, pg. 2). We find this explicit definition to be sufficient to convey to one of ordinary skill in the art that the inventor had possession of the claimed "bioactive agent" including "sulfurylase and luciferase" enzymes (Spec. i-f 5). Even in the event that the specific definition does not impart a definition, we find that one having ordinary skill in the art reading the claims and giving "bioactive agent" its ordinary and customary meaning in the art would have readily recognized the term to encompass any compound, molecule, or agent that exhibits bioactivity, which upon a review of the Specification would encompass "sulfurylase and luciferase" enzymes. See Phillips v. AWH Corp., 415 F.3d 1303, 1313 (Fed. Cir. 2005) ([t]he ordinary 9 Appeal2014-001572 Application 13/165,648 and customary meaning of a claim term is the meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention, i.e., as of the effective filing date of the patent application). See also Brookhill-Wilk 1, LLC v. Intuitive Surgical, Inc., 334 F.3d 1294, 1298 (Fed. Cir. 2003) ("In the absence of an express intent to impart a novel meaning to the claim terms, the words are presumed to take on the ordinary and customary meanings attributed to them by those of ordinary skill in the art"). With these understandings, we find the Examiner has not sufficiently met her burden of providing reasons why one of ordinary skill in the art would not consider the description sufficient to support the concept of bioactive agents including the disclosed enzymes. See Alton 76 F.3d 1175. 3. "[D]istributing said first and said second populations of microspheres in wells" limitation With respect to the claim requirement "distributing said first and said second populations of microspheres in wells," the Examiner determined the Specification does not support a claim reciting "enzymes attached to microspheres in the same wells" (Final Act. 10). Additionally, in a clarifying finding, the Examiner maintained that while the claims do not specifically require "in the same well," the "presence of microspheres containing both capture probes and detecting enzymes [in the same well] is the inherent consequence" of the claim requirements (Ans. 14). Additionally, the Examiner found that "while the disclosure contemplates detecting enzymes in the 'vicinity' of the sequencing reaction, it does not describe or suggest that the beads containing detecting enzymes be present in the same wells as the beads with capture probes to which the target is bound" (Ans. 14--15). In response, the Appellant argues the claims do not 10 Appeal2014-001572 Application 13/165,648 require the "in the same wells" as asserted by the Examiner and thus argues the rejection is in error (App. Br. 30-31 ). The Appellant also argues that, even under the Examiner's analysis, the disclosure specifically describes using a secondary enzymes during pyrosequencing and the use of these secondary enzymes generate a "chemiluminescent signal in the zone around the bead ... [and] [b]y attaching the secondary enzyme required to generate the signal, an increased concentration of the required enzymes is obtained in the immediate vicinity of the reaction" (Rep. Br. 8-9). The Appellant argues, even if the claims require "in the same wells," one of ordinary skill in the art would find the specification sufficiently describes the first and second microspheres are distributed in the same wells as required by the Examiners interpretation (id.). Here, again, we find the Examiner has not met her burden of providing reasons why one of ordinary skill in the art would not consider the description sufficient to support the claim requirement of "a distributing said first and said second populations of microspheres in wells." See Alton 7 6 F.3d 1175. As argued by the Appellant, the claims recites that the first and second microspheres are distributed "in wells on a surface of a substrate," rather than the more specific "same well" as argued by the Examiner. The claim is thus open to the presence of the microspheres in the same or different wells. The Specification discloses the substrate can include "discrete, individual sites" that may comprises "physical configurations such as wells or small depressions in the substrate that can retain the beads, such that a microsphere can rest in the well" (i-fi-f 103). Additionally, the Specification discloses "the surface of the substrate may be modified such that discrete sites are formed that can only have a single associated bead, or 11 Appeal2014-001572 Application 13/165,648 alternatively, the surface of the substrate is modified and beads may go down anywhere, but they end up at discrete sites" (i-fi-f 104). In other words, the microspheres can be at the same or different sites, as long as the sites are discrete, such as being "wells." Paragraph 54, as argued by the Appellant, indicates that the secondary enzymes may be "in the immediate vicinity of the reaction." The "immediate vicinity" provides support for the same well, or different, but adjacent, wells because in each case the secondary enzyme attached to the microspheres would be near the location of the reaction. In view of these disclosures, we find the claim limitation "distributing said first and said second populations of microspheres in wells" is supported by the written description. As persuasively argued by the Appellant (Rep. Br. 9) and conceded by the Examiner (Ans. 15), the Specification discloses during pyrosequencing "a chemiluminescent signal in the 'zone' around the bead" is generated by enzymes attached to the microspheres that are in the vicinity of the sequencing reaction (i-fi-f 0054). Additionally, the Specification, after discussing the distribution of microspheres in individual sites such as wells or small depressions, further discloses "the surface of the substrate is modified to allow attachment of the microspheres at individual sites, whether or not those sites are contiguous or non-contiguous with other sites" (i-fi-f 104). Thus, in view of these disclosures, we find that one of ordinary skill in the art would find that the Examiner's requirement that the claims inherently requires "distributing said first and said second populations of microspheres in the same wells" is supported by the Specification. 12 Appeal2014-001572 Application 13/165,648 4. "!Plroviding ... a uniform population of nucleotides to said wells" limitation With respect to the claim requirement "providing ... a uniform population of nucleotides to said wells," the Examiner determined that term "uniform population of nucleotides" was not defined or described in the original disclosure to comply with the written description requirement (Ans. 13). The Examiner further noted that the term "uniform population" was not defined by Appellant and noted "the 'uniformity' of having the same base is only one possibility" (id.). The Examiner further noted "[ fJor example, 'uniform population' could mean that each of the different types of dNTPs has the same concentration in the reaction mixture, or that the population includes only pyridines or only pyrimidines, etc" (id. 14). In view of these alternative meanings, the Examiner determined the limitation "uniform population of nucleotides" as required by the claims "introduces new matter into the disclosure" (id.). In response, the Appellant argues the term "uniform population of nucleotides' is sufficiently supported by the disclosure "the four deoxynucleotides (dATP, dGTP, dCTP and dTTP; collectively dNTPs) are added stepwise" (App. Br. 31 ). From this, the Appellant argues "[ o ]ne of skill in the art would understand this to mean that the deoxynucleotides are added in populations sharing a common base one at a time, that is, 'uniform populations"' (id.). The Appellant, in response to Examiner's articulated position, argued that"[ o ]ne of skill in the art at the time of filing the application would not have explored the Examiner's plethora of alternate definitions of the term 'uniform population' of nucleotides, but instead 13 Appeal2014-001572 Application 13/165,648 would have assumed, based on the specification and knowledge in the art, that they were the same nucleotide bases" (Rep. Br. 11 ). Because the Appellant has proffered insufficient factual evidence to the contrary, we agree with the Examiner's analysis and find that one ordinary skill in the art would not find the disclosure of common nucleotide base to be sufficiently descriptive to support "uniform population of nucleotides" as required by 35 U.S.C. § 112 i-f 1. Here, as found by the Examiner (Ans. 13), the requirement of "uniform population of nucleotides" is not specifically described by the disclosure and thus, again the relevant inquiry is whether one ordinary skill in the art would consider the disclosure sufficient to support "uniform population of nucleotides." See In re Alton 7 6 F.3d 1175. The Examiner has proffered evidence that one of ordinary skill in the art would reasonably interpret "uniform population of nucleotides" to have alternative interpretations and thus the Examiner found that one ordinary skill in the art would not find the disclosure of one possible interpretation to be sufficiently descriptive of all reasonable interpretations (Ans. 13). In view of this finding, we find that the Examiner has met her burden and the Appellant has proffered no factual evidence, besides mere attorney speculation, that refutes Examiner's findings and analysis or that demonstrates that one of ordinary skill in the art would find the disclosure that the nucleotides having a common base is sufficiently descriptive of "uniform population of nucleotides." See Scarborough, 500 F.2d 566. In sum, we hold that claim 1 violates the written description requirement of 35 U.S.C. § 112, i-f 1, and, therefore, cannot be entitled to benefit of priority or an earlier filing date as to any of the earlier-filed provisional or non-provisional applications. 14 Appeal2014-001572 Application 13/165,648 The Examiner also determined that claim 21, like claim 1, includes the following claim limitations "sulfonyltransferase enzymes," "covalently bound bioactive agents selected from sulfonyltransferase enzymes and luciferase enzymes" and "uniform population of nucleotides." Our discussion of these limitations in claim 1 applies equally with respect to claim 21. With respect to Rejections II, III, and IV, the Examiner determined that the claims do not "have support in either the original disclosure of the instant application or in the material incorporated by reference ... [and] [a]s a consequence, the priority date of the instant claims is the filing date of the instant application, June 21, 2011" and thus maintained "the rejection of the instant claims based on the Margulies et al. reference ... since it is proper prior art based on the priority date of the instant claims" (Ans. 35). In response, the Appellant contends that because the instant claims are "fully supported by the present specification, then they would be supported by the priority specifications in the family since they all contain virtually the same language" (Rep. Br. 4). As conceded by the Appellant (Rep. Br. 4), the earlier applications and the current application contain virtually the same disclosure language. Therefore, since we have held supra that the present claims fail to comply with the written description requirement as required by 35 U.S.C. § 112 i-f 1, it follows that the other identical, but earlier, disclosures also fail to comply with the written description requirement. Because there is not a continuous chain of copending applications that satisfy the requirements of the first paragraph of 35 U.S.C. § 112, we agree with the Examiner and find the invention recited in the claims is not entitled to an earlier effective filing 15 Appeal2014-001572 Application 13/165,648 date that is before the publication date of ivfargulies. See In re Hogan, 559 F.2d 609. The Appellant has set forth no additional substantive arguments regarding the merits of the Examiner's factual findings, reasoning and conclusions of obviousness for Rejections II, III, and IV, stating "[a]ll of the Examiner's rejections of the pending claims as obvious rely wholly or in part upon Margulies, published in 2005 ... five years after the effective priority date of the pending application, it is not prior art, and thus cannot support a claim under 35 US.C. 103(a)" (App. Br. 32). Because we rejected this argument supra and found the Appellant's reliance on an earlier effective filing date misplaced, we summarily affirm Rejections II, III, and IV for essentially the reasons as set forth in the Final Rejection. SUMMARY For these reasons and those set forth in the Examiner's Answer, the Examiner's final decision to reject claims 1-11 and 14--25 is affirmed. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(l). AFFIRMED 16 Copy with citationCopy as parenthetical citation
