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.

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

“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.

“not present in the written description whose benefit is sought it must be shown that a person of ordinary skill would have understood, at the time the patent application was filed, that the description requires that limitation.” Hyatt v. Boone, 146 F.3d 1348, 1353 (Fed. Cir. 1998) (emphasis added). In other words, where the written description fails to disclose an element explicitly, “the applicant must show that any absent text is necessarily comprehended in the description provided and would have been so understood at the time the patent application was filed.” Id. at 1354–55 (emphases added). At this stage of the proceeding, we do not find persuasive Patent Owner’s contention that a person of ordinary skill in the art would have recognized that authentication software has a “private key” that forms an “integral part of the authentication software component and/or is embedded therein” (Prelim. Resp. 13 (quoting Ex. 1001, 5:39–40)), in view of the cited section in the Detailed Description describing the authentication software as comprising the unique serial number, the unique software ID and/or a private encryption key, but only the unique serial number or the unique software ID is embedded therein. See Ex. 1001, 5:39–49. That is, we are unpersuaded at this stage of the proceeding that the person of ordinary skill in the art will directly and unambiguously deduce from the ’773 application as filed that the “private encryption key” is embedded in the authentication software, as Patent Owner contends. Prelim. Resp. 13. Instead, we find persuasive Petitioner’s contention that the ’480 patent (i.e., the ’773 application) merely teaches storing the digital signing algorithm in a secure part of the BIOS 44 but is silent as to storage of the private key.

“The Specification of the ’480 patent discloses secure area 62 only accessible to BIOS 44, comprising applications and storage locations not reported to operating system 48 (Ex. 1001, 8:62–9:1), wherein, as shown in Figure 3, secure area 62 comprises secure storage location 60, recovery application 56, and authentication software 54. Id. at 9:7–11. That is, the Specification shows “secure memory inaccessible to said operating system” as a location that holds software not accessible to operating system 48. Id. Nothing in the Specification, or the general knowledge in the art, limits “secure memory inaccessible to said operating system” to Ellison’s “isolated storage area 70,” or precludes Ellison’s “secure platform 200,” as Patent Owner proposes. Prelim. Resp. 35–36. In fact, nothing in the Specification or the general knowledge in the art limits the “storage” to any amount of time in the secure memory. We are unpersuaded by Patent Owner’s apparent position that software that is loaded into a secure location of execution is not software that is “stored” in a “secure memory” location. Prelim. Resp. 35–36. In view of the Specification and the general knowledge in the art, we determine that the term “stored in said secure memory inaccessible to said operating system” encompasses being held in any secure location that is determination here is preliminary, and the parties are invited to address this claim construction issue at trial, if so desired.” slip op. at 25

According to Petitioner, “[a] user is not an element of the operating system and processor operating in isolated execution mode, and therefore 6 The issue of whether the preamble is limiting need not be resolved at this stage of the proceeding because, regardless of whether the preamble is limiting, Petitioner shows sufficiently for purposes of institution, and Patent Owner does not dispute, that the combination of Ellison and Muir teaches a method for performing an electronic transaction between first and second transaction parties, as recited in the preamble. See Realtime Data, 912 F.3d at 1375 (noting that we need only construe “only those terms that . . . are in controversy”). Ex. 1003 ¶ 92). Petitioner then contends that Ellison discloses “a secure platform 200 that ‘includes the OS nub 16, the processor nub 18, a key generator 240, . . . , all operating within the isolated execution environment.’” Pet. 58 (citing Ex. 1006, 8:25–32; Ex. 1003 ¶ 95). Petitioner also contends that “the private key 204 can be stored in the cryptographic key storage 155 and in a multiple key storage of the non-volatile flash memory 160,” and “only the OS nub 16 can retrieve the private key.” Id. at 59–60. According to Petitioner, because “the OS nub 16 is within the secure platform and isolated environment,” it would have been obvious to a person of ordinary skill in the art (POSITA) that “the cryptographic key storage 155 and the non-volatile flash memory 160 are secure storage locations so that the private key 204 can be accessed securely by OS nub 16.” Id. (citing Ex. 1003 ¶ 96). Thus, Petitioner contends that “Ellison explicitly teaches that the OS nub 16 and private key 204 shown in platform 200 all operate within the isolated execution environment,” which “would indicate to a POSITA that private key 204 is stored in a secure memory and is inaccessible to a user of said electronic device.” Id. Nevertheless, Petitioner contends that Muir “explicitly teaches a private key 167 stored in a restricted memory space 170 which is inaccessible to the operating system.” Id. at 60 (citing Ex. 1008, 7–9, 3). Petitioner then contends that Ellison’s OS nub 16 “retrieves the encrypted private key 204 and decrypts it for use in the isolated environment.” Pet. 61 (citing Ex. 1006, 8:33–65, 11:1–12:26).

“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.

“For the above reasons, we are persuaded that the ’031 patent’s priority applications (pre-AIA applications) provide written description support for the claim limitation that “that the “output system” (claim 6) or “output device” (claim 19) can be an “Internet appliance.” Thus, we are not persuaded by Petitioner that claims 6 and 19 have an effective filing date after March 16, 2013.

“Finally, the definition of output device in the priority ’765 Application (as in the Specification of the ’031 patent) is that an “[o]utput device [] is an electronic system capable of outputting digital content … Any device capable of playing or reading digital content in voice (e.g., music, speech) or data (e.g., text, document) is also a possible output device.” Prelim. Resp. 15 (alterations in original) (quoting Ex. 1011 (’765 application) ¶ 89, Ex. 1001, 16:29–41). An Internet appliance does fall within that definition.

NTP, 654 F.3d at 1277. Instead, the Examiner entered the amendments and subsequently allowed the ’912 application with the subject matter added from Chu ’886. Ex. 1009, 419 (Notice of Allowance and Fee(s) Due). The incorporation by reference statement in the transmittal form also was never objected to by any Examiner during prosecution of the ’882 application (Chu ’330), the ’758 application (initial parent application), and all eight continuation applications in the priority chain of the ’797 patent, as well as Chu ’777 and all six reissue applications in the priority chain of Chu ’777, as noted in our Decision Denying Institution in IPR2021-00607, Paper 7 at 20. Moreover, none of the Examiners required the applicant to change its benefit claims from “continuation” to “continuation-in-part” in those continuation applications. 20 For the foregoing reasons, the ’882 application identified Chu ’886 with particularity and would have directly led an ordinarily skilled artisan to the document intended to be incorporated. Accordingly, we determine that Petitioner fails to show that the Examiner erred in determining that the ’882 application (Chu ’330) properly incorporated Chu ’886 by reference. In addition, as discussed above, Petitioner admits that the ’758 application (the initial parent application) incorporated by reference the ’882 application. Pet. 28; see also Ex. 1013, 4:50−53.
