GREENHUT, ANNETTE R. REIMERS, and SEAN P. O’HANLON, Administrative Patent Judges. O’HANLON, Administrative Patent Judge. DECISION ON APPEAL Appeal 2015-007325 Application 12/509,422 STATEMENT OF THE CASE John Walley et al. (Appellants)1 appeal under 35 U.S.C. § 134 from the Examiner’s March 19, 2014 final decision (“Final Act.”) rejecting claims 1—4, 6, 7, 9, 11—14, 16, 17, and 19-22.2 We have jurisdiction over this appeal under 35 U.S.C. § 6(b). We AFFIRM. SUMMARY OF THE INVENTION Appellants’ disclosure is directed to “a method and system for calibrating a local GNSS [(Global Navigation Satellite Systems)] clock using non-GNSS system clocks in a GNSS enabled mobile device.” Spec. 12. Claim 1, reproduced below from page 24 (Claims App.) of the Appeal Brief, is illustrative of the claimed subject matter: 1. A method for communication, the method comprising: receiving two or more system clocks from two or more non-Global Navigation Satellite Systems (GNSS) communication networks; selecting a calibration clock from said received two or more system clocks based on a status of a corresponding one of said system clocks; calibrating a local GNSS clock of said GNSS enabled mobile device using said selected calibration clock; and converting a GNSS signal received by said GNSS enabled mobile device to a baseband GNSS signal utilizing said calibrated local GNSS clock. 1 The Appeal Brief identifies Broadcom Corporation as the real party in interest. Appeal Br. 3. 2 Claims 5, 8, 10, 15, and 18 are canceled. Appeal Br. 25, 27 (Claims App.) (filed Mar. 2, 2015). 2 Appeal 2015-007325 Application 12/509,422 REJECTIONS3 Claims 1—4, 6, 7, 9, 11—14, 16, 17, and 19-22 stand rejected under 35 U.S.C. § 112, first paragraph, as failing to comply with the enablement requirement. Claims 1—4, 6, 7, 9, 11—14, 16, 17, and 19-22 stand rejected under 35 U.S.C. § 112, second paragraph, as being indefinite. Claims 1—4, 6, 7, 9, 11—14, 16, 17, and 19-22 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Abraham (US 7,053,824 B2, issued May 30, 2006) and Ladd (US 2009/0322601 Al, published Dec. 31, 2009). Claims 1—4, 6, 7, 9, 11—14, 16, 17, and 19-22 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Jazra (US 8,009,519 B2, issued Aug. 30, 2011). ANALYSIS Enablement Rejection Appellants argue independent claims 1,11, and 21 together. Appeal Br. 12—15. We select claim 1 as representative. See 37 C.F.R. § 41.37(c)(l)(iv). The Examiner determines that “the [Specification does not enable selecting a calibration clock based on its status.” Final Act. 3. The Examiner recognizes that “[t]he [Specification states that a clock’s status may be ‘active’ or ‘inactive’ but does not describe what is meant by an 3 A rejection of all the pending claims under 35 U.S.C. § 112, first paragraph, as failing to comply with the written description requirement has been withdrawn. See Final Act. 2—3; Ans. 2. 3 Appeal 2015-007325 Application 12/509,422 ‘active’ or an ‘inactive’ communication network system clock, and the terms are not well-known in the art.” Id. (citation omitted). Continuing, the Examiner explains that although “the terms ‘active’ and ‘inactive’ have plain and ordinary meanings in many contexts,” “one of ordinary skill would not know what is meant by an ‘active’ or ‘inactive’ system clock.'” Id. at 11. The Examiner finds that “[t]he [Specification only teaches that a ‘system clock’ is used to calibrate a ‘GNSS-clock’” and also “refers to a ‘system clock’ as a ‘timing signal,”’ but “[n]o other description is provided.” Id. at 12 (citing Spec, 13, 17). The “Examiner concedes that any such ‘system clock’ received from a communication network could be reasonably described as ‘active’ according to the dictionary definition of the term,” but determines that “it is unclear under what circumstances such a clock could be described as ‘inactive’.” Id. Appellants argue that although “the Specification does not explicitly define the terms ‘active’ and ‘inactive,’ a person of ordinary skill in the art would understand their definitions.” Appeal Br. 13. Appellants explain that the Specification sets forth that a GNSS-enabled mobile device may receive two or more system clocks from non-GNSS communication networks, and the GNSS receiver may calibrate the local GNSS clock using “the received system clocks of the cellular network 130 andlor the WiMAX network 140.” Id. (quoting Spec. H 13, 25). Appellants state, therefore, that the Specification “provides that only one of these system clocks is used to ‘calibrate [the] associated local GNSS clock,’ namely is ‘active’, whereas the other system clock is not used to ‘calibrate [the] associated local GNSS clock,’ namely ‘inactive’.” Id. at 13—14 (alterations in original). 4 Appeal 2015-007325 Application 12/509,422 We are not persuaded by Appellants’ arguments. Claim 1 requires that the calibration clock be selected based on its status, which Appellants define as being whether or not it is selected to be the calibration clock. Such circular reasoning fails to clarity how one of the two or more received system clocks is selected based on its status, and fails to apprise us of error in the Examiner’s rejection. Appellants further argue that “‘[a]n active system clock means a system clock that is actually utilized within a system or network to clock signals to maintain corresponding communication’ and an ‘inactive system clock means a system clock that is not actually utilized within a system or network to clock signals.’” Id. at 14 (alteration in original) (quoting Amendment, 17 (filed Nov. 30, 2010)). Thus, Appellants argue, a person of ordinary skill would be able to tell “whether a system clock is actually being utilized within a system or network, i.e., active, or is not actually utilized within a system or network to clock signals, i.e., inactive.” Id. at 14—15. We understand Appellants to be asserting that “status,” as used in claim 1, means whether the particular system clock is active or inactive. See also id. at 5, 15—16 (discussing active and inactive system clocks). The Examiner disagrees, determining that even using Appellants’ definitions, “one of ordinary skill would not understand how to make the determination of whether a received system clock is active or inactive.” Ans. 3. According to the Examiner, “the best that one of ordinary skill could reasonably conclude is that any system clock that is received from a communication network is an active clock,” and “[a]ny inactive clock would not be able to be received, as it is not actually being used. This, however, 5 Appeal 2015-007325 Application 12/509,422 provides no basis for selecting between a plurality of received clocks.” Ans. 3—A. Appellants reply by asserting that “the terms ‘active’ and ‘inactive’ — even if not explicitly defined in the specification — are well known terms.” Reply Br. 5. Appellants further assert that “a person of ordinary skill in the art would clearly understand the Specification to teach selecting a calibration clock by, for instance, reading the status of the received clocks from memory 308 and selecting the active clock.” Id. at 5—6 (referencing Spec. 33, 36). Notably, Appellants acknowledge that “it is unclear to the Examiner ‘under what circumstances such a clock could be described as “inactive”’” (Appeal Br. 13), but Appellants fail to explain how an inactive system clock could be received, as required by claim 1. “[T]o be enabling, the specification of a patent must teach those skilled in the art how to make and use the full scope of the claimed invention without ‘undue experimentation.’” Genentech, Inc. v. Novo Nordisk, A/S, 108 F.3d 1361, 1365 (Fed. Cir. 1997) (alteration in original) (quoting In re Wright, 999 F.2d 1557, 1561 (Fed. Cir. 1993)). “‘The scope of the claims must be less than or equal to the scope of the enablement’ to ‘ensure that the public knowledge is enriched by the patent specification to a degree at least commensurate with the scope of the claims.’” Sitrickv. Dreamworks, LLC, 516 F.3d 993, 999 (Fed. Cir. 2008) (quoting Nat 7 Recovery Techs., Inc. v. Magnetic Separation Sys., Inc., 166 F.3d 1190, 1195—96 (Fed. Cir. 1999)); see also In re Fisher, 427 F.2d 833, 839 (CCPA 1970) (“[T]he scope of the claims must bear a reasonable correlation to the scope of enablement provided by the specification to persons of ordinary skill in the art.”). 6 Appeal 2015-007325 Application 12/509,422 When rejecting a claim under the enablement requirement of § 112, the Examiner bears an initial burden of setting forth a reasonable explanation as to why the scope of protection provided by that claim is not adequately enabled by the description of the invention provided in the specification of the application; this includes providing sufficient reasons for doubting any assertions in the specification as to the scope of enablement. In re Wright, 999 F.2d at 1561—62. If the Examiner meets this burden, the burden then shifts to the Applicant to provide suitable proofs indicating that the specification is indeed enabling. Id. at 1562 (citing In re Marzocchi, 439 F.2d 220, 223—24 (CCPA 1971)). We determine that the Examiner has met this burden and Appellants have failed to persuade us that the Specification provides enabling support for claim 1. Here, as noted by Appellants, the Specification sets forth that memory 308 may store executable instructions that “may be utilized to indicate active system clocks received from external communication networks such as, for example, the cellular network 130 and/or the WiMAX network 140.” Spec. 133 (emphases added). As further noted by Appellants, the Specification also sets forth that the calibration clock is selected from the received system clocks according to its status as being active or inactive. Id. 136. This is in keeping with the use of “status” in the Specification, which consistently defines the status as being either active or inactive. See Spec. H 13, 36, 39, 41. We thus construe “status” as used in the claims as meaning either active or inactive. See GPNE Corp. v. Apple Inc., 830 F.3d 1365, 1370 (Fed. Cir. 2016) (“[W]hen a patent ‘repeatedly and consistently’ characterizes a claim term in a particular way, it is proper to construe the claim term in accordance 7 Appeal 2015-007325 Application 12/509,422 with that characterization.” (citations omitted)). We also adopt the definitions of “active” and “inactive” as proposed by Appellants supra. What the Specification fails to explain, and Appellants fail to address, is how an inactive system clock would be received from a non-GNSS network. Claim 1 requires that the set of system clocks, from which the calibration clock is selected, is received from non-GNSS communication networks. Appeal Br. 24 (Claims App.). System clocks are timing signals that are used as reference frequency sources for communication. See Spec. 127; see also Harry Newton, Newton’s Telecom Dictionary: The Official Dictionary of Telecommunications 692 (Ray Horak ed., 14th ed., 1998) (defining system clock as “[t]he clock designated as the reference for all clocking in a network of electronic devices such as a multiplexer or transmission facilities management system”). As the recited received system clocks necessarily are utilized to maintain corresponding communication with the associated non-GNSS communication network from which each of such system clocks is received, the received system clocks are, therefore, active system clocks. See Appeal Br. 14 (defining active system clock). Thus, all clocks within the set of received system clocks are active, and the Specification fails to explain how the calibration clock is selected “based on a status” of being active or inactive as required by claim 1. See Ans. 3^4. Accordingly, we sustain the rejection of claim 1, and its dependent claims 2-4, 6, 7, 9, and 22, claim 11, and claim 21, and its dependent claims 12—14, 16, 17, 19, and 20, as failing to comply with the enablement requirement. 8 Appeal 2015-007325 Application 12/509,422 Indefiniteness Rejections First Ground Appellants argue all of the claims together. Appeal Br. 15—16. We select claim 1 as representative. See 37 C.F.R. § 41.37(c)(l)(iv). The Examiner finds claim 1 to be indefinite for reasons similar to those discussed above regarding the enablement rejection, determining that use of the term “status” renders the claims indefinite because the [Specification does not describe what said term means with respect to a communication network system clock, and the meaning is not well-known in the art. The [Specification only states that a clock’s “status” may be “active” or “inactive” but does not describe what is meant by an “active” or an “inactive” communication network system clock, and the meanings are not well-known in the art. Final Act. 4 (citing Spec. ^fl[ 13, 36, 39, 41). Appellants present arguments similar to those discussed above with respect to the enablement rejection. Appeal Br. 15—16; Reply Br. 6—7. A claim is indefinite when it contains language that is “ambiguous, vague, incoherent, opaque, or otherwise unclear in describing and defining the claimed invention.” In re Packard, 751 F.3d 1307, 1311 (Fed. Cir. 2014). For the same reasons as set forth above, we conclude that one of ordinary skill would not understand how the calibration clock is selected from the “received two or more system clocks based on a status of a corresponding one of said system clocks'1'’ as required by claim 1. Appeal Br. 24 (Claims App., emphasis added). Accordingly, we sustain the rejection of claims 1—4, 6, 7, 9, 11—14, 16, 17, and 19-22 as being indefinite. 9 Appeal 2015-007325 Application 12/509,422 Second Ground The Examiner presents an additional ground of rejection for claims 4 and 14, which depend from claims 1 and 21, respectively, and require that the calibrating occur “without using an external circuitry.” Appeal Br. 25, 27 (Claims App.). The Examiner determines that “the language ‘calibrating said local GNSS clock without using an external circuitry’ is indefinite because the [Specification does not describe what such a circuitry would comprise or how calibration is performed without it, and one of ordinary skill would not understand what is meant.” Final Act. 5. The Examiner explains that “the claims do not clearly define where any of the steps are performed, and it is therefore unclear what the ‘external circuitry’ is external to.” Ans. 5. Appellants traverse, arguing that “a person of ordinary skill in the art would clearly understand claims 4 and 14 exclude the use of ‘external circuitry’to calibrate the local GNSS clock.” Appeal Br. 16. Appellants note that the Specification explains that a GNSS-enabled mobile device, a GNSS receiver, a GNSS clock calibrator, and a host processor may be operable to perform certain functions without using external circuitry. Reply Br. 7—8 (citing Spec. Tflf 13, 20, 27, 32, 41). Thus, Appellants argue, “a person of ordinary skill in the art would be reasonably appraised of the scope of the claim terms as excluding calibration circuitry that is external to the GNSS receiver or mobile device.” Id. at 8. We are persuaded of error regarding claim 14, which depends from claim 21. Claim 21 recites “a receiver” including “a calibrator configured to calibrate a local GNSS clock of said GNSS enabled mobile device utilizing said selected system clock.” Appeal Br. 28 (Claims App.). Thus, one of 10 Appeal 2015-007325 Application 12/509,422 ordinary skill would understand that claim 14 precludes the use of circuitry external to the receiver. Claim 4 depends from claim 1, which does not specify any component that performs the recited steps of receiving, selecting, calibrating, and converting. Appeal Br. 24 (Claims App.). Thus, we agree with the Examiner that “it is therefore unclear what the ‘external circuitry’ is external to.” Ans. 5. Accordingly, we sustain this ground of rejection as to claim 4, and do not sustain this ground of rejection as to claim 14. Obviousness Rejections In view of our determination that claims 1—4, 6, 7, 9, 11—14, 16, 17, and 19—22 are indefinite, it follows that the prior art rejections of these claims must fall because they are necessarily based on speculative assumptions as to the meaning of the claims. See In re Steele, 305 F.2d 859, 862—63 (CCPA 1962). It should be understood, however, that our decision in this regard is based solely on the indefiniteness of the claimed subject matter, and does not reflect on the adequacy of the prior art evidence applied in support of the rejections. DECISION The Examiner’s decision to reject claims 1—4, 6, 7, 9, 11—14, 16, 17, and 19—22 under 35 U.S.C. § 112, first paragraph, is affirmed. The Examiner’s decision to reject claims 1—4, 6, 7, 9, 11—14, 16, 17, and 19—22 under 35 U.S.C. § 112, second paragraph, is affirmed. 11 Appeal 2015-007325 Application 12/509,422 The Examiner’s decision to reject claims 1—4, 6, 7, 9, 11—14, 16, 17, and 19—22 under 35 U.S.C. § 103(a) is reversed. 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)(iv). AFFIRMED 12 Copy with citationCopy as parenthetical citation
