When I weigh the evidence, I find it to be one-sided, with all of the expert testimony weighing against Petitioner or avoiding the issue altogether. Thus, I would not find that Petitioner has met its burden to prove, by a preponderance of the evidence, that Zhao teaches claim limitation 1e. Moreover, even if the Majority is correct about how Zhao’s RCR algorithm works, all that shows is that the detection of object presence in a previous image can be used to disambiguate segments (e.g., limbs) of an already detected object (e.g., a person), not that it can be used to detect the object in the image in the first place, as required by the claim language. For this additional reason, I would not find that Petitioner has met its burden.” slip op. at 84

    “Patent Owner’s expert, Dr. Goodrich, proposes what Patent Owner characterizes as “a somewhat different level,” namely “an individual with at least a bachelor’s degree in Computer Science or related area and two years of experience developing software tools and/or computer systems for use in the area of audio or video creation, encoding, and/or distribution.” PO Resp. 13; Ex. 2007 ¶ 50. Although we agree that the respective articulations are “somewhat different,” they are generally similar, and our Decision does not depend on nuanced distinctions regarding the level of ordinary skill. Indeed, Dr. Goodrich describes his proposed articulation as “approximate,” such that “more work experience could compensate for less education or more education could compensate for less work experience.” Ex. 2007 ¶ 50. Because we find Petitioner’s proposal reasonable, consistent with the level of skill reflected by the prior art, and supported by Dr. Freedman’s testimony, we adopt it for this Decision. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art may reflect an appropriate level of skill in the art). We nevertheless note that we would reach the same ultimate conclusion that claims 1, 3, 5, 9, 12, 13, and 15 (but not claims 20 and 21) have been shown to be unpatentable by a preponderance of the evidence were we to adopt Patent Owner’s proposal.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed board ownDecided for patent owner

    “We agree with Patent Owner’s contention that the emphasized sentence defines the term “content-related.” See PO Resp. 15–16 (Patent Owner arguing that “[t]here are thus three strong indications of lexicography: (1) ‘content-related’ is set off by quotation marks; (2) the patentee used the word ‘is’ to describe the term ‘content-related’; and (3) the patentee states what ‘content-related’ is ‘understood to mean.’” Nor does Petitioner disagree that the sentence is definitional. See Tr. 8:15–16 (referring to the “term content-related as it’s defined in the specification”). Indeed, in the Starz litigation, the district court also treated the sentence as definitional, a fact that we find significant as a matter of comity. See Ex. 1018, 111:24–112:1 (district court judge stating at Markman hearing, “I’m going to adopt . . . the express definition provided in the specification”). But like the district court, we discern insufficient reason to adopt the additional gloss that Patent Owner seeks to apply to the definition of “content-related.” That is, Patent Owner proposes that we additionally construe the phrase “syntactical meaning” within the definitional statement to arrive at Patent Owner’s proposed construction. PO Resp. 16–20. According to Patent Owner, “[t]he specification makes clear, through its use of consistent and repeated examples, that ‘syntactical meaning’ requires a specific relationship between the data segments within a data file: succeeding data segments within a data file must be ordered so as to present the content in its intended sequence when rendered.” Id. at 17 (citing VirnetX Inc. v. Cisco Sys., Inc., 767 F.3d 1308, 1317–19 (Fed. Cir. 2014); Alloc, Inc. v. ITC, 342 F.3d 1361, 1368–71 (Fed. Cir. 2003)). Patent Owner adds that the claims, the context provided by the problems solved by the ’794 patent, and the cross-examination testimony of Petitioner’s expert, Dr. Freedman, all support this additional aspect of Patent Owner’s proposed construction. Id. at 18–20. Relying on additional direct testimony by Dr. Freedman, Petitioner counters this position as “improperly import[ing] limitations from the specification that are not required by the claims” and “render[ing] other portions of claim 1 superfluous.” Reply 3 (citing Ex. 1016 ¶ 22); see Tr. 10:18–20 (Petitioner explaining at oral hearing that “the syntax information is simply just identification information which is used to find out what the order of the files is. But the identification information does not by itself indicate the order. It’s just an identifier.”). We agree with Petitioner that it would be imprudent to adopt Patent Owner’s additional gloss because, “[w]hile claims must be construed in light of the specification, . . . limitations from the specification are not to be read into the claims, . . . for ‘[i]t is the claims that measure the invention.’” Golight, Inc. v. Wal-Mart Stores, Inc., 355 F.3d 1327 (Fed. Cir. 2004) (quoting SRI Int’l v. Matsushita Elec. Corp. of Am., 775 F.2d 1107, 1121 (Fed. Cir. 1985) (other citations omitted). It is apparent that the Applicant for the ’794 patent understood how to define terminology recited in the claims, but chose to limit its definition of “content-related” in terms of the broader phrase “syntactical meaning” rather than through narrower specific reference to presentation order. In addition, claims 1 and 9 already specify “sequentially outputting the first and second data segments according to their chronological sequence,” which supports Petitioner’s observation that requiring an additional sequential order to “content-related . . . data segments” renders other portions of claim 1 superfluous.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Prosecution history disclaimer / disavowalDisclaimer not foundDecided for petitioner

    “As a basic principle of claim interpretation, prosecution disclaimer promotes the public notice function of the intrinsic evidence and protects the public’s reliance on definitive statements made during prosecution.” Omega Engineering, Inc. v. Raytek Corp., 334 F.3d 1314, 1323 (Fed Cir. 2003) (citing Digital Biometrics, Inc. v. Identix, Inc., 149 F.3d 1335, 1347 (Fed. Cir. 1998)) (emphasis added). As such, a statement during prosecution qualifies as a disavowal of claim scope only if it is “so clear as to show reasonable clarity and deliberateness” and “so unmistakable as to be unambiguous evidence of disclaimer.” Id. at 1325 (citations omitted). “Consequently, for prosecution disclaimer to attach, [Federal Circuit] precedent requires that the alleged disavowing actions or statements made during prosecution be both clear and unmistakable.” Id. at 1325–26. “The party seeking to invoke prosecution history disclaimer bears the burden of proving the existence of a clear and unmistakable disclaimer that would have been evident to one skilled in the art.” Mass. Inst. of Tech. v. Shire Pharms., Inc., 839 F.3d 1111, 1119 (Fed. Cir. 2016). And “[s]tatements by the patent owner are not considered in a vacuum; rather, the skilled artisan would look at the record as a whole in assessing claim scope.” Galderma Lab’s v.

We have reviewed the prosecution history, which we summarize supra § I.A.3., and we have particularly reviewed those portions highlighted by Patent Owner. See PO Resp. 32–40. We reach the same conclusion as the district court in the Starz litigation that the standard for attachment of prosecution disclaimer is not met. See Ex. 1018, 109:15–22 (district court stating at Markman hearing, “I’ve also carefully reviewed the portions of the prosecution history relied on by VideoLabs, including the patentee’s arguments regarding the Shin and Rosenau references, and I’m up [sic: not6] persuaded there was a clear and unmistakable disclaimer of all assignment rules that perform assignments by using exact timing information”). slip op. at 20

Amneal Pharm., LLC, 895 F.3d 1347, 1356 (Fed. Cir. 2018) (quoting In re Hall, 781 F.2d 897, 898–99 (Fed. Cir. 1986)). A reference is considered “publicly accessible” if it was “disseminated or otherwise made available to the extent that persons interested and ordinarily skilled in the subject matter or art, exercising reasonable diligence, can locate it.” Id. at 1355–56 (citing In re Wyer, 655 F.2d 221, 226 (CCPA 1981)). Petitioner treats this requirement as having two aspects, namely (1) whether a person of ordinary skill could reasonably have found RemoteCentral.com and (2) whether such a skilled artisan could reasonably have found RadioShack on RemoteCentral.com. Reply 8–13; see also Tr. 33:25–34:8 (Patent Owner asserting that there are two aspects to the analysis on public accessibility: “The first is whether a [person of ordinary skill in the art] would have known to arrive at the website containing the prior art reference.

    “addressed squarely by the principles set forth in Hulu, which addresses the standards at the institution stage and during the trial for evaluating evidence proffered to show asserted art qualifies as a printed publication. Specifically, after a petitioner has presented “evidence sufficient to establish a reasonable likelihood that the reference was publicly accessible before the critical date of the challenged patent,” such that trial is instituted, “some limited opportunities exist for the petitioner to present new evidence later.” Hulu at 13–14. These “limited opportunities” include “in a reply to the patent owner response,” provided that the additional evidence is “responsive to the prior briefing” and provided that the additional evidence does not require “completely reopen[ing] the record, by, for example, changing theories after filing a petition.” Id. at 14–15. Although Patent Owner contends that “[t]his is not an example of permissible rebuttal evidence, but rather a belated attempt to fill a gap in the evidence in the Petition,” we disagree. See Sur-reply 6. Rather, the 7 Patent Owner appears to refer incorrectly to Exhibit 1040 instead of Exhibit 1041 when identifying “articles allegedly referring to RemoteCentral.com.” See Sur-reply 5–6. progression within the instant proceeding comports well with the Hulu framework. During the preliminary proceeding, Petitioner came forth with “evidence sufficient to establish a reasonable likelihood that [RadioShack] was publicly accessible before the critical date of the challenged patent,” just as Hulu demands. Hulu at 13; Inst. Dec. 23 (“[W]e determine that Petitioner’s showing regarding public accessibility of RadioShack is sufficient under the standard we apply at this stage of the proceeding.”). Patent Owner challenges RadioShack’s status as a printed publication in its Response, just as Hulu contemplates. Hulu at 15; PO Resp. 28–41. And Petitioner submits additional evidence that replies to that challenge without changing its theory that RadioShack qualifies as a printed publication by virtue of its accessibility on the RemoteCentral.com web site and in light of date indicia on RadioShack itself.8 See Hulu at 15–16; Reply 7–13. Moreover, in determining that Petitioner’s additional evidence directed at RemoteCentral.com is properly considered, we are further mindful of the Federal Circuit’s endorsement that “the petitioner in an inter partes review proceeding may introduce new evidence after the petition stage if the evidence is a legitimate reply to evidence introduced by the patent owner.” Anacor Pharm., Inc. v. Iancu, 889 F.3d 1372, 1830–81 (Fed. 8 In its Reply, Petitioner also relies on evidence of publication of RadioShack on Radio Shack’s own public website and on “a third location,” hifi-remote.com. Reply 14. As we discuss below, we determine that the presence of RadioShack on RemoteCentral.com is sufficient to qualify RadioShack as a printed publication. We therefore do not reach the issue of whether presence on either the Radio Shack web site or on hifi-remote.com is an improper new theory raised by Petitioner in its Reply. See Tr. 8:13– 9:23 (Petitioner discussing whether reliance on hifi-remote.com presents a different theory than set forth in the Petition). Cir. 2018); see also Vidstream LLC v.

    “We agree with Patent Owner regarding the ordinary meaning of the term “respectively.” Specifically, we understand that the word “respectively” can be an adverb that means “for each separately or in turn, and in the order mentioned.” The use of “respectively” as an adverb in the English language requires parallelism. See Ex. 3002. In other words, there must be a direct one-to-one correspondence and specific referents must be individually identified before there can be a “parallel list” of attribute values applicable to each, in that order. The term “respectively” also can be an attributive adjective that means “concerning or appropriate to each of several individually.” Id. In the present case, the term “respectively” appears to modify “the selected distributed devices.” Because specific referents are not individually identified, we understand the term to act as an attributive adjective modifying each of several selected distributed devices. Although we agree with Patent Owner regarding the use of the term “respectively,” we do not understand its use to require “the selected distributed devices to cause each selected distributed device to separately appear to network-connected user devices as a dedicated NAS device.” We cannot construe individual terms in isolation. Rather, we must consider claims as a whole in view of the specification. Specifically, we must consider the implications of other terms recited in claims 1 and 13 (e.g., “location information”) and how the claims are supported by the disclosed embodiments.” slip op. at 11

Patent Owner notes that Petitioners’ declarant, Dr. Kubiatowicz, testified on cross-examination that “somebody coming directly out of college, likely, would need a couple of extra years to understand this,” and that “a little bit of professional experience might help them -- would help them understand the details involved in this case.” Id. (citing Ex. 2002, 25:13–14; 26:2–5). Patent Owner’s declarant, Dr. Shenoy, testified that, “at the time of the ’827 patent, a person of ordinary skill in the art should have had a bachelor’s degree in computer science, computer engineering, electrical engineering, or equivalent, with 1–2 years of work experience in the field of computer networking, storage systems, or a related field.” Ex. 2003 ¶ 19. According to Dr. Shenoy, “[l]ack of experience can be remedied by additional education or vice versa.” Id. Based on our review of the ’827 patent, the types of problems and solutions described in the ’827 patent and cited prior art, and the testimony of Dr. Kubiatowicz and Dr. Shenoy, we adopt and apply Patent Owner’s definition of a person of ordinary skill in the art, specifically that a person of ordinary skill in the art at the time of the claimed invention would have had “a bachelor’s degree in computer science, computer engineering, electrical engineering, or equivalent, with 1–2 years of work experience in the field of computer networking, storage systems, or a related field.” See id.

    “Despite Patent Owner’s arguments, we find that Carter’s policy element 290 (a software module) is configured to assess unused or under-utilized storage resources in selected distributed devices of the plurality of distributed devices. We understand policy element 290 to satisfy this limitation because Carter specifically discloses that policy element 290 “acts as a controller to determine the availability of resources, such as printer capabilities, hard-disk space, available RAM and other such resources.” Ex. 1140, 36:27–29 (emphases added). We credit the testimony of Dr. Kubiatowicz, who during his deposition stated, “I would say this policy controller certainly can evaluate the hard disk space on the local node, but could also potentially evaluate storage throughout the system by communicating with other nodes.” Ex. 2002, 86:13–16; see id. at 88:5–7; see also id. at 88:12–16 (“What I said was that this policy element is determining the availability of resources. So it’s assessing whether or not hard disk space of various sorts is available. So it’s availability, not just available.”); see id. at 88:18–89:18, 90:5–91:1. We further credit the testimony of Patent Owner’s declarant, Dr. Shenoy, who testified that Carter discloses “determin[ing] the free volume space available for allocation.” See Ex. 1144, 142:19–20 (referencing Ex. 1140, 19:14–17). Reading directly from Carter, Dr. Shenoy further testified that Carter discloses “request[ing] the total available space information and us[ing] this information to quickly determine whether to proceed with the allocation processing.” Id. at 142:14–17, 143:1617. In view of the explicit disclosure of Carter and the testimony of both declarants, we find that Carter’s controller performs an “assessment” in order to “determine the availability of resources.” Additionally, Carter states that policy controller 290 “can employ any of the suitable heuristics to direct the elements, such as the paging controller, disk directory manager, and other elements to dynamically distribute the available resources.” Ex. 1140, 36:29–37:2. Thus, we agree with Petitioner’s argument, as supported by the testimony of Dr. Kubiatowicz, that policy element 290 assesses the unused or underused storage resources when it determines the availability of such resources and uses some heuristics when distributing those resources that were assessed. See Pet 39 (citing Ex. 1102 ¶ 118). Accordingly, based on the entirety of the record before us, we find Petitioner has shown by a preponderance of the evidence that Carter discloses the “assessing” limitations of claims 1 and 13.” slip op. at 31

    “We agree with Patent Owner that Petitioner fails to offer sufficient explanation as to why a person of ordinary skill in the art would have combined the teachings of Carter and Condor. Rather, Petitioner appears to argue that, based on the advantages described by Condor (Ex. 1017, 5), and using well-known techniques with unspecified predictable results, a person of ordinary skill in the art would have had sufficient reason to combine these disparate elements taught in the prior art references to render the challenged claims obvious. Pet. 61–66. Yet, other than Petitioner’s cursory assertion of “advantageously incorporat[ing] the central coordinator in Condor to provide a centralized mechanism to manage resource sharing” (Pet. 66), which cites equally cursory and unsupported testimony by Dr. Kubiatowicz (Ex. 1102 ¶ 199), Petitioner fails to identify what particular advantages or efficiencies would have prompted a person of ordinary skill in the art to combine Condor’s scheduler with Carter’s system. Furthermore, Dr. Kubiatowicz’s testimony regarding predictable results and obviousness to try are similarly lacking in elaboration and substantiation. See Ex. 1102 ¶¶ 200–201. Such conclusory statements and unspecific testimony without evidence on the record cannot satisfy the Petitioner’s burden of demonstrating obviousness.

Although Petitioner has not provided a sufficient rationale to combine in this asserted ground of unpatentability, Petitioner has otherwise demonstrated that claims 4, 6, 16, and 18 are unpatentable under 35 U.S.C. § 102(b) because they are anticipated by Carter. Petitioner, however, has not asserted claims 7 and 19 are unpatentable under any other ground in this proceeding.

    “We are not persuaded by this reasoning. As Petitioner observes, the embodiments of the ’624 patent identified by Patent Owner are characterized as “examples,” and a person of ordinary skill “would understand that the example scenarios of the specification are not necessarily limiting on the claims.” Reply 3 (citing Ding Supp. Decl. ¶ 6). In addition, Petitioner notes that claim language in related patents owned by Patent Owner explicitly refers to participants, evidencing Patent Owner’s understanding “how to expressly create participant-specific voting requirements in claims.” Id. at 3. At the oral hearing, Patent Owner suggested that explicit reference to participants in such other claim language “was because it wanted to clarify that each participant got a single vote,” and explained its position that, in the claims at issue in this proceeding, “participant is implicit in the claim language as it is.” Tr. 78:16–25. But the claims are directed to a “communications apparatus,” and recite “votes” in the context of what the “particular communications channel” “receives.” Nothing within the structure of the claims requires resolving the origin of such votes. Furthermore, Patent Owner’s proposed construction is inconsistent with the construction it agreed to before the district court in the Qualcomm Litigation. In that litigation, the parties agreed that the term “vote” should be construed as “a binary expression (to use or not to use),” a construction that makes no reference to the origin of the “vote” as from a participant or otherwise. Ex. 1014, 6. We see no compelling reason to excuse the inconsistency by adopting a narrower construction when the Board applies a claim-construction standard (broadest reasonable interpretation) that could only result in the same or a broader construction.

In this instance, Petitioner refers to two embodiments of Gerten “in which a first participant communicates with a second participant via a normal sequence and with another participant via an adaptive hopping sequence.” Reply 5. First, Figure 3 of Gerten is reproduced below. Figure 3 illustrates “methodology for determining and communicating channels to be avoided to a remote device.” Ex. 1003, col. 2, ll. 4–6. As illustrated in the drawing, a master unit performs a discovery process (block 110) upon connecting with a new slave unit. Ding Decl. ¶¶ 60, 64.

If a second slave unable to use interference avoidance enters the piconet, standard frequency hopping is used. Supp. Ding Decl. ¶ 9. Under Patent Owner’s characterization of Gerten, entry of the second slave into the network would require the first slave necessarily to revert back to the default hopping sequence. Id. ¶ 10. But this would undermine the stated benefits of Gerten, which explicitly discloses: The above process can be applied to a Bluetooth example and includes identification of a Bluetooth device’s ability to support interference avoidance, the measurements of signal strength on all channels and identification of which channel should not be used without violating the FCC rules, a method of modifying the Bluetooth hop sequence so that it will avoid channels containing strong or fixed interferers while still supporting standard Bluetooth hopping with other non-enabled members of the piconet and a method of relating necessary interference avoidance information to the remote Bluetooth devices.

Rather, Petitioner relies on Cuffaro’s teaching of communicating performance data between devices, and applying that teaching to the system described by Gerten. See Reply 9– 10.

    “Two criteria have evolved for determining whether prior art is analogous: (1) whether the art is from the same field of endeavor, regardless of the problem addressed, and (2) if the reference is not within the field of the inventor’s endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved. In re Clay, 966 F.2d 656, 658–59 (Fed. Cir. 1992) (citing In re Deminski, 796 F.2d 436, 442 (Fed. Cir. 1986); In re Wood, 599 F.2d 1032, 1036 (CCPA 1979)). Patent Owner understates the degree to which Petitioner addresses the analogousness of the art by focusing on Petitioner’s contention that Gerten and Cuffaro are in the same field of endeavor. PO Resp. 40 (citing Pet. 30). Petitioner also addresses the second prong of the Clay test by providing reasons why a person of skill in the art would use the transmitted performance data of Cuffaro in the selection process of Gerten, including improved accuracy in determining the impact on the receiver unit from the interference on a given channel. See Pet. 31. We agree with Petitioner’s reasoning and find that Cuffaro and Gerten are analogous art to the claimed invention at least because they are reasonably pertinent to the particular problem with which the inventor was involved. We conclude that Petitioner has demonstrated, by a preponderance of the evidence, that claims 2, 14, and 26 are unpatentable under 35 U.S.C. § 103(a) over Gerten and Cuffaro.” slip op. at 26

    “1. “hopping sequence” Each of challenged claims 9, 10, 22, and 24 recites a “hopping sequence.” Petitioner’s declarant, Dr. Zhi Ding, attests that the phrase is “a well-understood term of art.” Ding Decl. ¶ 35 (citing Ex. 1016, 127–33). Consistent with Dr. Ding’s testimony, we applied a preliminary construction of “hopping sequence” in the Institution Decision as “the order in which the communications network hops among the set of frequencies.” Dec. 7. That construction is not contested by Patent Owner, and we adopt it for this Final Written Decision.” slip op. at 8

    “participants in such other claim language “was because it wanted to clarify that each participant got a single vote,” and explained its position that, in the claims at issue in this proceeding, “participant is implicit in the claim language as it is.” Tr. 78:16–25. But the claims are directed to a “communications device,” and recite “votes” in the context of what the “particular communications channel” “receives.” Nothing within the structure of the claims requires resolving the origin of such votes. Furthermore, Patent Owner’s proposed construction is inconsistent with the construction it agreed to before the district court in the Qualcomm Litigation. In that litigation, the parties agreed that the term “vote” should be construed as “a binary expression (to use or not to use),” a construction that makes no reference to the origin of the “vote” as from a participant or otherwise. Ex. 1018, 6. We see no compelling reason to excuse the inconsistency by adopting a narrower construction when the Board applies a claim-construction standard (broadest reasonable interpretation) that could only result in the same or a broader construction. See Amazon.com, Inc. v. Barnesandnoble.com, Inc., 239 F.3d 1343, 1351 (Fed. Cir. 2001) (“A patent may not, like a ‘nose of wax,’ be twisted one way to avoid anticipation and another to find infringement.” (quoting Sterner Lighting, Inc. v. Allied Elec. Supply, Inc., 431 F.2d 539, 544 (5th Cir. 1970))). Accordingly, we construe “votes to use a particular communications channel” as “expressions of preference for using the particular communications channel.”” slip op. at 10

    “(citing Melendez Decl. ¶ 32). Patent Owner contends that “Gerten’s disclosure is directed toward eliminating channels for use in an entire piconet as opposed to eliminating channels for use by certain participants within a piconet.” Id. (emphasis added). Patent Owner argues that Gerten does not disclose a selection kernel capable of maintaining synchronization between a master and more than one slave in a piconet, with the master and one slave using a default set of channels while the same master and a different slave use a different set of channels. Id. We are not persuaded that the absence of a specific teaching of such a selection kernel supports the conclusion that one of skill in the art would understand Gerten to function in the manner Patent Owner suggests. In this instance, Petitioner refers to two embodiments of Gerten “in which a first participant communicates with a second participant via a normal sequence and with another participant via an adaptive hopping sequence.” Reply 5. First, Figure 3 of Gerten is reproduced below. Figure 3 illustrates “methodology for determining and communicating channels to be avoided to a remote device.” Ex. 1003, col. 2, ll. 4–6. As illustrated in the drawing, a master unit performs a discovery process (block 110) upon connecting with a new slave unit. Ding Decl. ¶¶ 58, 61. If the slave unit is capable of using interference avoidance, the master unit begins the process of determining a modified set of channels for use (block 120). Id. ¶ 46. If a second slave unable to use interference avoidance enters the piconet, standard frequency hopping is used. Supp. Ding Decl. ¶ 9. Under Patent Owner’s characterization of Gerten, entry of the second slave into the network would require the first slave necessarily to revert back to the default hopping sequence. Id. ¶ 10. But this would undermine the stated benefits of Gerten, which explicitly discloses: The above process can be applied to a Bluetooth example and includes identification of a Bluetooth device’s ability to support interference avoidance, the measurements of signal strength on all channels and identification of which channel should not be used without violating the FCC rules, a method of modifying the Bluetooth hop sequence so that it will avoid channels containing strong or fixed interferers while still supporting standard Bluetooth hopping with other non-enabled members of the piconet and a method of relating necessary interference avoidance information to the remote Bluetooth devices.

  • Obviousness (§103) › Motivation to combine / reasonable expectation of success › Teaching awayTeaching away not foundDecided for petitioner

    “teaches away from the claim limitations. See PO Resp. 15. A prior-art reference does not teach away from the claimed subject matter unless the prior-art reference also criticizes, discredits, or otherwise discourages the solution claimed. See In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). In support of this contention, Patent Owner relies on testimony by Dr. Melendez that “the only selection kernels (Gerten Fig. 6 and Fig. 7) disclosed for the transceiver (Gerten Fig. 2) in Gerten are expressly not capable of providing the subject claimed limitations of the [’]624 patent as is discussed below, and so would serve only to teach away from the claim.” Melendez Decl. ¶ 32. Even if Dr. Melendez’s statement is accurate, such examples in Gerten do not meet the “teaching away” standard because the mere use of examples in a reference that function in a different way does not criticize, discredit, or otherwise discourage the solution claimed. In addition, “[t]eaching away is irrelevant to anticipation.” Seachange Int’l, Inc. v. C-Cor, Inc., 413 F.3d 1361, 1380 (Fed. Cir. 2005).” slip op. at 19
