“whether the motion to amend meets the statutory and regulatory requirements set forth in 35 U.S.C. § 316(d) and 37 C.F.R. § 42.121.” See Lectrosonics, Inc. v. Zaxcom, Inc., IPR2018-01129, Paper 15 at 4 (PTAB Feb. 25, 2019) (precedential). A “patent owner bears the burden of persuasion to show, by a preponderance of the evidence, that the motion to amend complies” with the applicable statutory and regulatory requirements. 37 C.F.R. § 42.121(d)(1). Specifically, a patent owner must demonstrate the following: (1) the amendment proposes a reasonable number of substitute claims; (2) the amendment responds to a ground of unpatentability involved in the trial; (3) the amendment does not seek to enlarge the scope of the claims of the patent; and (4) the amendment does not introduce new matter. See 35 U.S.C. § 316(d); 37 C.F.R. § 42.121(a)–(b). For the reasons explained below, Patent Owner satisfies its burden of persuasion to show that the amendments comply with the applicable statutory and regulatory requirements.” slip op. at 8

“Both parties rely on expert testimony for their respective positions relating to the number of years of experience needed to attain ordinary skill, but neither expert cites supporting evidence for their testimony. 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). Accordingly, we adopt a modified version of Petitioner’s proffered level of ordinary skill in the art, substituting “wireless communications” for “telecommunication.” Neither party, moreover, indicates the overall result would change based on a different definition.” slip op. at 18

“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

“2. Level of Ordinary Skill in the Art Snap proposes that a person of ordinary skill in the art at the time of the ’599 patent would have possessed “an undergraduate degree in electrical engineering, computer engineering, computer science or a related field along with at least two years of work experience in the field of content presentation and context-based systems/processes.” Snap Pet. 3 (citing Snap IPR, Ex. 1002 ¶¶ 30–32); Snap IPR, Ex. 1022 ¶ 32. Snap further asserts that additional “education can supplement practical experience and vice versa.” Id. In the Decision on Institution, we determined that Snap’s proposed description of the qualifications of a person of ordinary skill in the art aligned with the technology and claims of the ’599 patent. Snap Inst. Dec. 6–7. For this proceeding, Patent Owner and Dr. Martin apply this level of skill in the art. Snap PO Resp. 11–12; Snap IPR, Ex. 2003 ¶¶ 48–50.

“Dr. Martin also provides consistent testimony on this issue. Snap IPR, Ex. 2003 ¶¶ 81–82. Put simply, the Specification’s disclosure is that the set of rules for multiple content packages includes an expected response, and actions are then performed based on whether an expected response is or is not provided. Moreover, as Dr. Almeroth testifies, neither the claims nor the Specification use the term “unexpected response”—rather the Specification only identifies an “expected response.” Snap IPR, Ex. 1022 ¶ 42. Accordingly, the disclosures in Table 1 and the Specification support Dr. Almeroth’s testimony that a person of ordinary skill would have understood that “the claimed ‘determin[e/ing]’ limitation requires what it plainly recites: ‘determin[e/ing] whether the received response matches the expected response[]’. . . . [i]t does not require an unexpected response not known to the system.” Snap IPR, Ex. 1022 ¶ 51.” slip op. at 18

Reply 18 (citing Twitter IPR, Ex. 1005, 2 3, 5 (“A check . . . to see if the information from the database corresponds with the location sensor (i.e. a check on whether the learner is really keeping his/her schedule).”), Fig.1; Twitter IPR, Ex. 1025 ¶ 49; Twitter IPR, Ex. 1003 ¶¶ 85, 157–162, 238, 435, 451, 517; Twitter Pet. 20–21). Accordingly, the evidence of record support that Yau teaches that context triggers the display of a content piece, such as an exercise/test/quiz. Patent Owner also argues that Twitter asserts that PALLES’ content piece is “‘exercise[s],’ ‘test[s],’ and/or ‘MP Quiz[zes],’” but also contends that Yau’s “formal assessment” is the claimed content piece. Twitter PO Resp. 32. Patent Owner argues that “Twitter points back to its limitation 12.1 PALLAS evidence for the purported ‘content piece’” and also does not mention Yau for limitation 12.5 and 12.6 and “only conclusorily states that ‘PALLAS in view of Yau renders obvious triggering an exercise/test/quiz.’” Id. 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. Further, Patent Owner overlooks Petitioner’s assertion that it is implementing PALLAS’s context-triggerbased content display using Yau’s teachings of displaying assessments/questions based on context. Twitter Pet. 43. Patent Owner also asserts that in the PALLAS-Yau combination, Twitter does not explain how a person of ordinary skill in the art would have combined the prior art in the manner Petitioner alleges. Twitter PO Resp. 42. 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. Id. at 43 (citing Twitter IPR, Ex. 2013 ¶¶ 142–144). The evidence of record does not support Patent Owner’s arguments.” slip op. at 115
- 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

“content for output.” Id. at 89. We determine, however, that Petitioner’s argument under Step 2A Prong One that claim 1 is directed to the “obtaining content for output” is not substantially different from the Examiner’s determination that claims 1‒20 recite “collecting information, analyzing it, and displaying certain results of the collection and analysis.” Compare Pet. 37–88 (citing e.g. Electric Power), with Ex. 2001, 193–194 (also citing Electric Power). In both cases, the argument is the same or substantially the same, i.e., that similarly identified subject matter of the claim is obtaining (collecting) data and displaying (outputting) it. Nevertheless, as to Step 2A Prong Two, we determine that the claims at issue in the ’096 prosecution differ in material ways from the ’903 patent claims at issue in this PGR. Specifically, the ’096 patent claims recite a touchscreen interface not recited in the ’903 patent claims. Additionally, the ’903 claims focus on the “output device” as performing the patented steps but in the ’096 prosecution history the “‘information apparatus performs the patented steps and “is integral to the claims” (as the Applicant argued). See Ex. 2008 [comparison of ’096 prosecution claims and ’903 claims]; Ex. 2001, 150; see also Pet. 89 (“the claims at issue in the ’067 application were different than the claims of the ’903 patent addressed here.”). rejection and arguments in the ’096 prosecution history turns on whether the claims in this PGR recite different elements that must be determined to integrate the judicial exception into a practical application (i.e., Prong Two of Step 2A). Petitioner argues that an essential element different than the ’096 claims, i.e. the output device, does not integrate the judicial exception into a practical application because the claims do not amount to an improvement to computer functionality. Pet. 37–72. We find this a close case. Nevertheless, due to the differences in the claims, we determine that the Examiner’s withdrawal of the § 101 rejection in light of the applicant’s arguments regarding the claim being directed to a specific technical solution is not substantially the same argument that Petitioner’s presents in the Petition as to Prong Two of Step 2A.” slip op. at 22

“C. Lack of Written Description Support Petitioner contends that the challenged claims are unpatentable for lack of written description for the same reasons it contends the ’903 patent is PGR eligible. Pet. 13–36. The Specification of the ’903 patent has substantially the same disclosures as the Specification of the ’413 application relied on by Patent Owner (see Prelim. Resp. 20) to which the ’903 patent claims priority. Having determined that the disclosures in the ’903 patent Specification and the ’413 application is insufficient to provide written description support for the at least claim 1, we also determine that Petitioner has demonstrated a reasonable likelihood that at least claim 1 is unpatentable for the same reasons. Thus, we exercise our discretion and institute post grant review of claims 1–20 challenged under this ground. See SAS Inst. Inc. v. Iancu, 138 S. Ct. 1348, 1369–60 (2018).” slip op. at 33

“in the art at the time of the invention] would have understood that an output system/device could be (or include) an information apparatus. Prelim. Resp. 24. We determine that Patent Owner’s argument has a logical flaw––i.e., the fact that a particular device could be used alternately as an information apparatus or an output device does not necessarily mean that it was known by one of ordinary skill in the art to use a combined information apparatus/output device and have the new combined device perform all the additional functions required by the claims. “The knowledge of ordinary artisans may be used to inform what is actually in the specification, but not to teach limitations that are not in the specification, even if those limitations would be rendered obvious by the disclosure in the specification.” Rivera v. Int’l Trade Comm’n, 857 F.3d 1315, 1322 (Fed. Cir. 2017) (“Rivera”). “The question is not whether a claimed invention is an obvious variant of that which is disclosed in the specification . . . . It extends only to that which is 1997). Patent Owner has not pointed to any disclosure in the ’413 application teaching that an “output device” can perform the functions of the “information apparatus” including its interactions with the “output device.” For example, claim 1 recites “wirelessly receiving, by the output system . . . output data from at least one server of the one or more servers over the Internet.” Ex. 1001, 37:28–32. At this stage, we find sufficiently persuasive Petitioner’s argument, which we discuss above, that the only written description support for an “output device” that performs the claimed functions by accessing the Internet provided by Patent Owner is not an “output device” but an “information apparatus.” Prelim. Resp. at 27–29.” slip op. at 29
