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.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

    “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. See supra III.B.4 and IV.B. Further, we are not persuaded that Lee’s transmitting by broadcast is” slip op. at 26

Patent Owner’s arguments overlook Twitter’s assertion, with Dr. Turnbull’s supporting testimony, that a person of ordinary skill in the art would have understood that Yau’s formal assessments are “tests with answers for comparing against learner’s responses to assess knowledge/performance/skill (contrasting with ‘un-assessed’ exercises whose responses are unchecked).” Twitter Pet. 43; Twitter IPR, Ex. 1003 ¶ 154.

    “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

More specifically, the district court determined, and we concur based on the present record, that “client device” is “a device that is operating in the role of a client by requesting services, functionalities, or resources from other devices” and a “first server” functions as “a server that is not the client device.” On this record, Petitioner has demonstrated that Mithyantha’s second appliance 200’/200b functions as the claimed “second client device,” as it operates as a client by requesting services, functionalities, or resources from other devices, that is, it transmits HTTP web requests over the network to a server.

Further, we do not find that Petitioner’s applications of the claim elements to Mithyantha are arbitrary because they are consistent with the district court’s claim construction of the respective claimed elements and the elements’ functions and roles, as discussed. Moreover, Mithyantha discloses that its appliances can provide different functions (see e.g. Ex. 1009, 5:31–33, 8:65–67, 9:8–21, 9:53–55; 23:58–64), and may be implemented in many forms. That is, the implementation of appliance 200 is generally described as being on any form of computing device such as “computing device 100,” and “computing device 100 can be any workstation, desktop computer, laptop or notebook computer, server, handheld computer, mobile telephone.” See id. at 13:65– 142, 16:58–64. We do not agree with Patent Owner’s allegations regarding a required architecture. Patent Owner does not explain how these requirements are recited in the limitations of claims. Instead, at this juncture, it appears that the arguments are an attempt to impermissibly introduce limitations into the claim that are not recited. Similarly, we do not agree with Patent Owner’s arguments on required anonymity because this requirement is not recited in the claims.” slip op. at 18

As we discuss in more detail below, Facebook relied on the ordinary and customary meaning of the term “facts and assertions” in its Petition, and then when PARC raised an alternative construction of the term in its Response, Facebook responded to those arguments. 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. See 37 C.F.R. § 42.23(b) (permitting a petitioner to respond to arguments in a patent owner response); Anacor Pharm., Inc. v. Iancu, 889 F.3d 1372, 1380–81 (Fed.

Also, as PARC acknowledges, Facebook’s expert Mr. Schmandt stated in deposition that he assumed, for his analysis, that the term “context graph” requires a “graph-based model.” PO Resp. 22 (citing Ex. 2019, 36:16–37:8); see also PO Sur-reply 4. Thus, because Facebook’s analysis of Cheng is consistent with the assumption that “context graph” has the meaning PARC proposes in this proceeding, we do not need to construe the term “context graph” to reach our decision.

    “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

Dr. Houh testifies that an ordinarily skilled artisan would have used Wiser’s voucher ID in Eyal’s play-list because delivery servers may have a “limited number of active streams of data being delivered at any one time,” so that generating and tracking reservations by the content server using voucher IDs is necessary. Ex. 1003 ¶ 144 (citing Ex. 1006, 14:65−15:1). We agree with and credit Dr. Houh’s testimony, and we find that such an artisan of ordinary skill would have understood that, in Eyal in combination with Wiser, the voucher ID provided in the play-list is uniquely associated with the client device and a viewing session of the media. Ex. 1003 ¶ 151 (citing Ex. 1006, 8:30−33, 15:23−28). We do not agree with Patent Owner’s assertion that “Wiser teaches away from video.” PO Resp. 33 (citing Ex. 2012 ¶ 174). “A reference may be said to teach away when a person of ordinary skill, upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994). Here, nothing in Wiser would discourage a relevant artisan from applying its teachings to video media, as Patent Owner alleges. Patent Owner’s argument of teaching away is based on speculation. As discussed above, Wiser’s disclosure is not limited to audio media. Ex. 1006, 1:5−8, 1:23−26, 3:8−10; Ex. 1083, 145:20−147:21. The “mere disclosure of alternative designs does not teach away.” In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). Moreover, KSR instructs us that “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize 20 that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417.

We rely, instead, on Dr. Houh’s testimony, summarized above, that there would be advantages in combining the teachings of Eyal and ASF Files. Houh Decl. ¶¶ 140–141.

This testimony is unavailing for several reasons. First, the evidence of record links Windows Media Player with use of ASX Files. See Ex. 1017, 1 (“ASX files are simply text files that act as links from Web pages to ASF files on Windows Media Services or HTTP servers.”).

Reply 12. One of those required elements of the claimed play script is “one or more instructions for use by the communication device together with the at least one URL to cause the at least one portion of the requested media to be streamed to the communication device.” See claim element 1.c.4, Ex. 1001, 51:8–11. We find that there is inadequate written description in the ’519 application of “instructions . . . to enable the communication device to obtain the at least one portion of the requested media.” Reply 8–9. We agree with Petitioner that the “presentation identification” relied on by Patent Owner (Ex. 2015, 7) does not provide “instructions…to enable the communication device to obtain the at least one portion of the requested media.” Reply 13. Instead, the “presentation identification” “identifies a particular presentation . . . and its associated media.” Id. (quoting PO Resp. 36). Absent an adequate written description in the ’519 application of these claimed features, Patent Owner’s attempt to obtain the benefit of the filing date of that application for the challenged claims of the ’635 patent fails. “It is elementary patent law that patent claims are entitled to the benefit of the filing date of an earlier filed application only if the disclosure of the earlier application provides support for the claims of the later application, as required by 35 U.S.C. § 112.” PowerOasis, Inc. v.
