The diagnostic test passage therefore only describes a diagnostic test of the build material property but does not describe a subsequent diagnostic test to assess whether an operational parameter is suitable for the printer. Based solely on the diagnostic test passage and the prosecution history, a possible interpretation may be that the operational parameter determination in claim element 1b encompasses the diagnostic testing in claim element 1c. That is, “performing a diagnostic test to determine whether the operational parameter is suitable for the three-dimensional printer” in claim element 1c is subsumed as part of “determining an operational parameter of a fabrication process using the three-dimensional printer based upon the data, the operational parameter including at least one of a build platform temperature, a build volume temperature, an infill requirement, a rafting requirement, a support structure requirement, and a cooling requirement” in claim element 1b.” slip op. at 15

See Ex. 1002 ¶ 33; Ex. 2002 ¶ 15. Our decision is the same regardless of whether the length of experience is two years or three. We find Patent Owner’s proposed “wireless communications” is more consistent with the ’958 patent than Petitioner’s proposed “telecommunication,” which encompasses a variety of technologies including, e.g., landline and wireless telephones, cable, and satellite. See Ex. 1001, 1:11–62 (describing the invention in terms of wireless communications).

    “We agree with Patent Owner that the recited second type SIBs exclude first type SIBs. The plain meaning of “first type” and “second type” indicates that the first type and second type are different in kind. RMTA 22 (App. A). Our interpretation is consistent with the Specification, which explains that second type SIBs exclude first type SIBs. As Patent Owner points out, the ’958 patent discloses “first type of system information (1TYP SIB) is . . . essential . . . for initial system access” and “second type of system information (2TYP SIB) is nonessential system information . . . defined as all other types of information, and thus excludes the [] information required for initial access.” Id. at 11–12 (citing Ex. 1001, 8:34– 46); see also Ex. 1001, Abstract (interchangeably using the terms second type and non-essential). Despite Petitioner’s argument that this disclosure is non-limiting and directed to a disclaimed example embodiment (Opp. 8–9), Petitioner could not identify any embodiment, among the approximately forty disclosed embodiments, describing something other than the first type SIB being essential information and the second type SIB being non-essential information. Tr. 22:18–26. Even the Petition acknowledges that “the ’958 Patent further classifies a second type of system information, the ‘non-essential’ SI, which is defined as all other types of information excluding that first type of information required for initial access.” Pet. 5. Furthermore, the prior art of record suggests that a person of ordinary skill would have understood second type SIBs exclude first type SIBs. See Ex. 1008 ¶ 48 (describing two categories of system information, “essential SI” and “Other SI”). Patent Owner’s expert also understood the recited first and second type SIBs as being mutually exclusive. See Ex. 1011, 49:10–13. For the above reasons, we do not agree with Petitioner that the recited second type SIB lacks any requirements, nor do we interpret claims 7 and 8 such that the first type SIB could be a second type SIB.” slip op. at 19

    “(d) Limitation 7h: Analysis We agree with Patent Owner that Petitioner’s arguments with respect to limitation 7h are insufficient because they fail to address the limitation as written and improperly incorporate previous arguments by reference. For example, Petitioner did not map the recited “group identifier” when opposing Patent Owner’s Revised Motion to Amend. See Opp. 16–17. In its Sur-reply, Petitioner contends that limitation 7h’s requirement of transmitting the group identifier was previously “set out in Patent Owner’s prior papers,” but does not refer to any specific papers or exhibits. Pet. Surreply 11–12. We decline to search for and piece together Petitioner’s arguments and evidence to develop a persuasive theory of unpatentability. See 37 C.F.R. section 42.6(a)(3). Petitioner similarly failed to address adequately where Lee discloses or suggests the recited “compressed format” and “plural parameters.” See Opp. 16–17. Aside from the above concerns, we also do not see sufficient explanation with respect to limitation 7h’s requirement that the transmitting by broadcast be based on a comparison of the value tag. Petitioner argues that, because Patent Owner does not dispute limitation 7g, “it would have been obvious to a POSITA to use the same value tag[] to determine the system information broadcast in Lee’s compressed format embodiment.” Pet. Sur-reply 12. This conclusory statement is not supported by any citations to evidence and was improperly introduced in the Sur-reply. Moreover, whether it was obvious to determine what system information is broadcast is not commensurate with the claim scope because limitation 7h requires that the broadcasting (not the broadcast content) be based on a comparison of the value tag.

Patent Owner argues that “PALLAS says nothing about forcing quizzes, tests, or exercises on its users without the users asking for such exercises,” and a person of skill would understand that the combined system still requires that a student select a learning activity and that PALLAS’s system should be unobtrusive because learners “may have small time slots to engage in learning.” Id. (citing Twitter IPR, Ex. 2013 ¶ 168; Twitter IPR, Ex. 1004, 54). Patent Owner further contends that “Twitter’s conclusory, hindsight-driven statements” do not suffice and PALLAS teaches away from the modifications suggested by Twitter. Id. at 42–43 (citing Twitter IPR, Ex. 2013 ¶ 144). Patent Owner argues that because a learner may not have time to complete a test, a person of ordinary skill in the art would not be motivated to change PALLAS to trigger exercises/tests/quizzes based on location or time.

  • ScopeMotion to amend, grantedGranted

    “2. Enlarging Scope of Claims Patent Owner asserts that it proposes narrowing limitations in direct response to the grounds of unpatentability involved in this proceeding. See, e.g., Snap Mot. 3–4. Facebook argues Patent Owner is “improperly attempting to enlarge the scope of the original claims.” Facebook Pet. Opp. 1. Facebook asserts, “[i]f ‘an expected response’ means one or more expected responses, therefore, determining whether the received response ‘matches the expected response’ means that the received response must match [all of] the one or more previously-recited expected responses in the content package.” Id. at 3 (emphasis omitted). Facebook then argues “the term ‘predefined response’ is broader than ‘expected response,’” because “an ‘expected response’ does not include any conceivable or possible response; it is a response that is expected.” Id. at 4–5 (emphasis omitted). Twitter argues that “‘predefined response’ is broader than ‘expected response’ because a ‘predefined response’ can include any possible response as long as that response has been somehow defined in advance.” Twitter Pet. Opp. 2. We consider the amendments in view of the claim as a whole. Although the term “one predefined response” may be broader than “an expected response,” we also consider the amended portion “wherein the received response is expected if the received response matches one or more of the at least one predefined response,” and “the received response is unexpected if the received response does not match any of the at least one predefined response.” Unless the response had been predefined within the content package, any “received response” could not be considered “expected” under the claims, and the additional clause requires a match of the response with the predefined response to be deemed “expected.” This equates to an equivalent scope to the original claim. This is consistent with Dr. Martin’s testimony, which we credit, that he is not aware of a situation where the substitute but not original claims are infringed because “[t]he substitute claims would only be satisfied when a ‘predefined response’ in the substitute claims is an ‘expected response’ in the original claims.” Facebook IPR, Ex. 2023 ¶ 59.” slip op. at 136

See infra Sections IV.B.2, IV.C.4(a). Facebook’s Reply only responded to arguments raised in PARC’s Response and was not untimely.

    “We agree with the parties that a person of ordinary skill in the art would have understood the term “fact” to include an indication of truth, whereas an assertion need not include such an indication. However, we disagree with PARC that a person of ordinary skill would have considered the term “assertion” to exclude facts. Indeed, in its ordinary and customary meaning, a fact stored in a context graph would be a type of assertion. We appreciate PARC’s argument that when two different terms appear in a claim, they presumably refer to different things. See PO Resp. 27 (citing CAE Screenplates, 224 F.3d at 1317). And we agree that the two terms have different meanings in claim 1 based on the plain meaning of each term. However, the specification refers to “stor[ing] facts and assertions about a user’s behavior and interests,” which simply appears to identify a single category of data for storage, i.e., “facts and assertions,” without specifying a clear difference between “facts” and “assertions.” See Ex. 1001, 3:21–22. In any event, we find no evidence of record suggesting that either (1) the (citing Pet. Reply 8–9). Because Facebook appears to have been relying on what it regarded as the plain meaning of the terms without proposing an explicit construction, we do not interpret Facebook’s argument in the Petition (Pet. 20–21) to imply that there is no distinction between a fact and an assertion, and do not find Mr. Schmandt’s later testimony (see, e.g., Ex. 2019, 41:3–11) inconsistent with arguments made in the Petition. ordinary and customary meaning of the term “assertion” excludes facts, or (2) that the ’439 patent uses these terms in a way that departs from their ordinary and customary meaning. That claim 1 requires the presence of both “facts” and “assertions” does not render the two terms superfluous, as this would exclude prior art in which a context graph includes only assertions but not facts. On the other hand, a disclosure of a collection of facts would meet the term “facts and assertions” because a person of ordinary skill in the art would have regarded any subset of the facts to also be assertions.” slip op. at 15

    “embodiments that operate with a low frequency driving signal in a double-ended configuration, Patent Owner did not recite “low frequency” or “double-ended” in its claims and instead chose the broader term “first driving mode.” See In re Am. Acad. of Sci. Tech Ctr., 367 F.3d 1359, 1369 (Fed. Cir. 2004) (“We have cautioned against reading limitations into a claim from the preferred embodiment described in the specification, even if it is the only embodiment described, absent clear disclaimer in the specification.”). The fact that a limitation in the specification may define over the prior art does not justify importing that limitation into the claims unless a term is expressly defined such that the patentee becomes his own lexicographer or there is an express disavowal of claim scope. See GE Lighting Sols., LLC v. AgiLight, Inc., 750 F.3d 1304, 1308–09 (Fed. Cir. 2014). There is no evidence of an express disavowal here. As to lexicography, we disagree with Patent Owner’s contention that the Specification defines the phrase “first driving mode.” Patent Owner relies on the mere fact that the specification describes an embodiment with a first driving mode that has a low frequency driving signal and is in a “double-ended” configuration, but this is not sufficient to define the term. The specification does not require that a low frequency driving signal must necessarily be used. In fact the specification, although not entirely clear, suggests that the driving signal may be from a high frequency ballast. Ex. 1001, 51:8–14. Thus, the fact that the patent here discloses a low frequency driving signal does not mean that all the claims are directed to such a driving signal. See E-Pass Tech., Inc. v. 3Com Corp., 343 F.3d 1364, 1368–69 (Fed. Cir. 2003). Indeed, dependent claim 15 recites “the first driving mode is performed when the external driving signal is a relatively low frequency or voltage signal,” while the independent claims were directed to a more general driving signal. The doctrine of claim differentiation suggests that the independent claims here should not include explicit limitations of a dependent claim. See Phillips, 415 F.3d at 1315 (“[T]he presence of a dependent claim that adds a particular limitation gives rise to a presumption that the limitation in question is not present in the independent claim.”); Liebel-Flarsheim Co. v.

In any event, merely simple attributes [] for the above-described purpose”––and not even in close proximity to the “user characteristics” and “additional configuration” in paragraph 232––is not sufficient to provide support for “the user characteristic information includ[ing] the usedWith attribute and the equivalentTo attribute,” as recited in limitations [31.11], [32.12], and [35.7]. None of the cited portions (i.e., Ex. 2004 ¶¶ 232, 234, 253, 255–257, Table 13; Ex. 2005 ¶¶ 254–256, Table 13) indicate a sufficient connection or relationship, or the claimed inclusive relationship, between user characteristic information and the usedWith and equivalentTo attributes. Contra Reply Opp. Rev. 1 (Patent Owner arguing that the cited disclosures “clearly show this relationship between the claimed attributes and user characteristic information”). For the foregoing reasons, we determine that claims 31, 32, and 35 do not have sufficient written description support in the ’644 application and the ’092 application, either individually or collectively, and as such, contain new matter.” slip op. at 29

  • Novelty / Anticipation (§102) › Priority / effective filing date / continuation supportDecided for petitioner

    “are not entitled to a priority date earlier than March 16, 2012 (the filing date of PCT ’922), because the disclosure of KR10-2011-0023271 does not support at least the limitations of: “the adaptation set includes one or more attributes or elements that are common to each of the representations for that adaptation set,” as recited in independent claims 1 and 11, and the “SegmentTemplate” recited in independent claims 25. Patent Owner has not asserted, after institution, that the challenged claims are entitled to an earlier date. See Tech. Licensing Corp. v. Videotek, Inc., 545 F.3d 1316, 1327–28 (Fed. Cir. 2008) (indicating that patent owner bears a burden of production in arguing that the asserted references are not prior art based on entitlement to an earlier priority date). As such and for the reasons discussed below, Petitioner has persuasively demonstrated that DIS 23001-6, DIS 23009-1, and 3GPP TS 26.247 qualify as prior art to the challenged claims, because Petitioner has sufficiently demonstrated that the references were publicly accessible prior to the applicable priority date of March 16, 2012.” slip op. at 12

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
