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.

“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).

“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

“On this record, we do not find Patent Owner’s proposed experience level of at least five years in measurement and analysis of coefficient of friction to be supported. As to the necessity of experience in textile engineering and fiber science, Patent Owner’s position, although not supported by declarant analysis of the factors listed above, is consistent with the disclosure of the ’854 patent, which describes features of a mesh layer in textile and fiber terms. See e.g., Ex. 1001, 10:17–11:14, 12:65–13:8, 14:20–24. On the whole, however, we do not discern on this record how specific experience in textile engineering and fiber science of a person of ordinary skill would materially alter the outcome at this stage of the proceeding. For purposes of this decision only, we apply Patent Owner’s proposed definition of a person of ordinary skill in the art, except for the requirement of five years of experience in measurement and analysis of coefficient of friction.

“We agree with Petitioner that the ’854 patent specification does not include clear and explicit lexicography or a disclaimer that would support requiring “coefficient of friction” to be determined by a specific ASTM test method. The portion of the specification Patent Owner asserts as a definition of “coefficient of friction” (see Ex. 1001, 11:31–42) is a description of an embodiment; we find it does not express patentee intent to redefine the term. Further, the statement that “the coefficient of friction … may be determined using the … ASTM D1894 standard test method” (id. at 11:32–35) indicates that use of that specific test method is optional. Accordingly, in the absence of patentee lexicography or disavowal, we do not limit the scope of the term “coefficient of friction” to require that it be measured by a specific ASTM standard. Luminara Worldwide, LLC v. Liown Elecs. Co., 814 F.3d 1343, 1353 (Fed. Cir. 2016) (“Absent lexicography or disavowal, we do not depart from the plain meaning of the claims.”); In re Am. Acad. Of Sci.

We note that the ’854 patent specification sets forth a definition for the coefficient of friction between the surfaces of the mesh material and the slide surface. Ex. 1001, 4:38–46. As stated above, however, we do not expressly construe any claim term at this stage of the proceeding.

“Accordingly, the ’202 patent consistently and repeatedly characterizes the invention as incorporating tobacco in some form and ties the stated benefits of the invention to the inclusion of tobacco. Moreover, the Specification is directed to smoking articles containing tobacco, all of the embodiments include tobacco, and “the present invention” is described as a smoking article, where the smoking article includes tobacco.

“evaluated the subject matter of Riis during examination of the ’624 patent, we agree that Riis was before the Office, as discussed in connection with our analysis of the first part of the Advanced Bionics framework, above. Examiner T presumably was aware of Riis by virtue of having initialed an IDS containing Riis in the ’624 patent’s application and also by virtue of having initialed an IDS containing Riis in the ’067 Application, but Examiner T did not apply Riis in connection with the examination of the ’624 patent. On this record, Patent Owner also fails to show that the claims of the child application leading to the ’624 patent are substantially similar to those of the parent ’814 patent in which Examiner S considered Riis, and, thus, consideration of Riis during the prosecution of the ’814 patent does not equate to consideration of Riis during the prosecution of the ’624 patent. Regarding Patent Owner’s argument (2) that Petitioner fails to sufficiently show how the Examiner erred in evaluating the prior art, we find Petitioner’s arguments demonstrate that Examiner T, the examiner of the ’624 patent, did not apply Riis (or Wypych or Tatarka) during the examination of the’624 patent. As Petitioner argues, the error lies in that “the Examiner failed to consider the relevance of Riis as it applied to the pending method claims,” because although “Riis was considered during examination of the parent ’999 application, Riis was not similarly considered during examination of the ’018 application which led to the ’624 patent.” Pet. 76–77.

“Relying on Mr. Schmandt’s testimony, Facebook argues that a person of ordinary skill in the art “would have possessed at least a bachelor’s degree in electrical engineering or computer science, and two years of work experience in the field of context-based computer systems, such as the collection, processing and use of context data in computer systems capable of adapting their operation based on context.” Pet. 6 (citing Ex. 1002 ¶¶ 15– 18). Facebook also contends that a person might qualify as an ordinarily skilled artisan “with more formal education and less technical experience, or vice versa.” Id. For this proceeding, PARC does not dispute this proposed level of ordinary skill. PO Resp. 16–17. Because Facebook’s uncontroverted articulation of the level of ordinary skill in the art is supported by testimonial evidence and appears consistent with the types of problems and solutions in the ’439 patent, we adopt it for this decision.

“construction of the term “facts and assertions” or the identification of facts and assertions within Cheng. See Paper 23, 1–2. Having reviewed the arguments, we do not consider them untimely. 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.

“We agree with Facebook. As we discuss below, Cheng teaches a graph-based model that stores data in memory on a per-user basis. See infra Section IV.C.4(a); Ex. 1003, Fig. 7. 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

“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

“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.
