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.

“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.

However, we disagree with PARC that a person of ordinary skill would have considered the term “assertion” to exclude facts.

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.

“Id. at 7:24–8:4 (emphasis added). The ’928 application repeatedly makes clear that directionality and intra mode are related, but distinct concepts. They are not interchangeable as Patent Owner argues. On this point, we find Dr. Freedman’s explanation in paragraph 85 of his Declaration on the relationship between “intra mode” and “directionality” to be particularly well-reasoned and persuasive. As Dr. Freedman explains, [t]hroughout the ’928 application, the text uses the term “directionality” to refer to characteristics of neighboring blocks, whereas the term “intra mode” is used when referring to the current block. For example, the ’928 application describes that “directionality” of neighboring blocks is “estimated from the neighboring blocks” that “have already been reconstructed” while the “intra mode” is selected for the current block for purposes of reconstructing that current block. This is likely because the neighboring blocks “have already been reconstructed” and thus, the intra mode number that was used in reconstructing those blocks is no longer pertinent. Instead, what is pertinent in the ’928 application’s method is the directionality characteristic of those neighboring blocks. Phrased differently, in the ’928 application, directionality is a concept that is evaluated after performance of intra prediction (i.e., after reconstruction), whereas the intra mode or number is a concept used during performance of intra prediction. They are not equivalent in the context of the ’928 application. Ex. 1005 ¶ 86 (citing Ex. 1028, 11:14–12:4, 25:10–15; Ex. 1036, 706 (“The DCT coefficients gathered from the MPEG 2 process are used to estimate the directional features in a picture. The estimated directional features are then used to compute the intra prediction modes in the H.264 encoding stage.”)).8 Thus, we are persuaded by Dr. Freedman’s testimony, supported by Kalva, that these terms are not synonymous, as is Patent Owner’s and its expert’s position.” slip op. at 31

“’653 patent are not supported by Korean App. No. 6839. Claim limitation 34(d) requires that “a bit is sent on a reverse packet data control channel to indicate whether the mobile station has enough power and data to increase its data transmission rate on a reverse packet data channel,” and claim 37 recites a similar limitation. Ex. 1001, 20:19–22 (emphasis added), 20:44– 48. The ’653 patent discloses an MS_IAB bit that indicates whether the mobile station has enough power and data to increase its data transmission rate on a reverse packet data channel. Id. at 14:3–20. More specifically, the ’653 patent states that the MS_IAB value is set to “increase” when “transmission power margin (i.e., remaining transmission power) is above a certain level,” the “number of bits in the transmission buffer is above a certain level,” and “the data rate of the current transfer . . . is below a maximum data rate . . . set by the system.” Id. at 14:10–19. Thus, the ’653 patent’s disclosure of an MS_IAB supports limitation 34(d). This disclosure, however, does not appear in Korean App. No. 6839, and Patent Owner does not contend otherwise. See Pet. 8–9; Pet. Reply 3–4; Ex. 1002 ¶¶ 116–119; PO Resp. 31–46; PO Sur-reply 2–22. Nor is there any similar disclosure in Korean App. No. 6839 of a value that indicates whether the mobile station has enough power and data to increase its data transmission rate, whether referred to as an “MS_IAB” or otherwise. We also find that the RRI in Korean App. No. 6839 does not provide support for claim limitation 34(d). The relevant portion of the ’6839 application states that the base station determines “information on the increase and decrease of transmission data rate (Reverse Activity Bit, RAB) for each mobile station” and sends the RAB to the mobile station. Ex. 1011 ¶¶ 6–7. It then states that “the mobile station that has received its RAB information changes the transmission data rate one step at a time according to the RAB command and transmits it, and informs a base station of its transmission data rate through an RRI (Reverse Rate Indicator).” Id. ¶ 7 (emphasis added). The ’6839 application includes a comparable disclosure in two additional locations, paragraphs 22 and 44. Id. ¶¶ 22 (“the mobile station that has received its RAB information changes the transmission data rate one step at a time according to the RAB command and transmits it, and informs the base station of its transmission data rate through an RRI (Reverse Rate Indicator)”), 44 (same). These disclosures merely state that the RRI informs the base station of the mobile station’s transmission rate; they do not disclose that the RRI includes a bit that “indicate[s] whether the mobile station has enough power and data to increase its data transmission rate,” as the claims require.” slip op. at 27

“4. Motivation to Combine Samsung and Airvana Petitioner argues that one of ordinary skill would have been motivated to combine Samsung and Airvana because “Samsung incorporates Airvana by reference.” Pet. 39. “Specifically,” Petitioner asserts, “Samsung expressly references the disclosures of Airvana and then, importantly, makes a proposal that builds upon and improves Airvana’s ideas.” Id. Petitioner also argues that, even if Samsung and Airvana are “treated as entirely separate references,” one of ordinary skill would have been motivated to combine them because “Samsung specifically references and discusses the content of ‘Airvana’s proposal[] for 1xEV-DV’ in the context of reverse link rate control.” Pet. 40. “Moreover,” Petitioner contends, “Samsung was a contribution to the same 3GPP2 TSG working group (3GPP2 TSG-C WG5) as Airvana, so Samsung’s reference to ‘Airvana’s proposal[]’ for a dedicated control scheme for reverse link data rates could not be misunderstood.” Id. (citing Ex. 1004, 4; Ex. 1002 ¶¶ 161–163). Petitioner further argues that Samsung “states that its proposal for an increase availability bit (‘IAB’) from the mobile station ‘can be applicable for both common and dedicated control scheme[s] for reverse link data rate,” and that “Airvana proposes such a control scheme.” Id. (citing Ex. 1003, 5). Patent Owner does not argue a lack of motivation to combine Samsung and Airvana. See PO Resp. Based on the full trial record, including the testimony of Mr. Proctor, Petitioner has proven by a preponderance of the evidence that one of ordinary skill would have been motivated to combine Samsung and Airvana based on Samsung’s incorporation by reference of Airvana’s proposal, the fact that Samsung was a contribution to the same 3GPP2 TSG working group as Airvana, and Samsung’s statement that its proposal for an IAB can be applicable to a control scheme such as that proposed by Airvana.

Additionally, as discussed in Section II.E.5 above, we find that Petitioner has proven by a preponderance of the evidence that it would have been obvious to use C.S0002-0’s signal point mapping technique with Samsung’s (or Samsung/Airvana’s) messages with Samsung’s signaling by the base station to indicate whether the mobile station should increase, decrease, or maintain its current data transmission data rate. We disagree with Patent Owner’s contentions for the reasons discussed above in Section II.E.5. Consequently, based on the full trial record, we find that Petitioner has proven by a preponderance of the evidence that the combination of Samsung (or Samsung/Airvana) and C.S0002-0 teaches this limitation.” slip op. at 57

“Our conclusion is supported by the testimony of Mr. Proctor. Mr. Proctor testifies that “RRIs were adopted as part of prior art specifications, including for the [3GPP] cdma2000 High Rate Packet Data Air Interface at least as early as October 2000.” Ex. 1019 ¶¶ 6, 8 (citing Ex. 1018). As Mr. Proctor explains, the cdma2000 specification describes a “Reverse Rate Indicator Channel . . . used by the access terminal to indicate the data rate at which the Data Channel is transmitted.” Ex. 1019 ¶¶ 8–9 (citing Ex. 1018, 9-35). Mr. Proctor also testifies that “the Reverse Rate Indicator (RRI) symbols sent on the RRI Channel by the mobile station (access terminal) to the base station ‘indicate the data rate at which the Data Channel is transmitted.’” Id. ¶ 9 (citing Ex. 1018, 9-35). “In other words,” Mr. Proctor explains, “the mobile station sends RRI symbols to tell the base station the data rate at which the mobile is transmitting information on the reverse link’s Data Channel (the data Channel of the Reverse Traffic Channel), as the RRI Channel is used to indicate the data rate of the Data Channel being transmitted on the Reverse Traffic Channel.” Id. (citing Ex. 1018, 9-26, 9- 33, 9-34, 9-35, 9-39). Additionally, Mr. Proctor testifies that “RRIs are only briefly mentioned three times, in paragraphs 7, 22, and 48” in the ’6839 application, and “the prior art 3GPP specification has the same basic disclosure of RRIs as the ’6839 application: using the RRI to confirm to the base station what data rate the mobile station/access terminal is using.” Id. ¶¶ 7, 11 (citing Ex. 1018, 9-35; Ex. 1011 ¶¶ 7, 22, 48). “Indeed,” Mr. Proctor states, “the ’6839 application references the same data rates between 9.6 and 153.6 kbps on the reverse link that are referenced in the prior art [3GPP] specification.” Id. ¶ 11 (citing Ex. 1011 ¶ 16; Ex. 1018, 9-33, 9-35). We find this testimony to be credible because it is consistent with the disclosures of the ’6839 application and the 3GPP specification (Exhibit 1018). We also rely on and find credible Mr. Proctor’s testimony that “neither the ’6839 application nor the prior art High Rate Packet Data Specification disclose” an “RRI or other signal that comprises a bit that the mobile station sends to indicate it has sufficient power and data for a subsequent increase.” Ex. 1019 ¶ 12. As Mr. Proctor explains, “the only disclosure relating to the RRI within the ’6839 application” is the “single sentence[] referring to the RRI as informing the base station of its transmission data rate,” which is “repeated three times in separate paragraphs.” Id. (citing Ex. 1011 ¶¶ 7, 22, 48). We agree with and find credible Mr. Proctor’s testimony that this sentence “provides no additional teachings beyond what a [person of ordinary skill in the art] would have known to be conventional (e.g., beyond what was known in the current HDR system available at that time, and referenced within the ’6839 application),” id. ¶ 12, and that “[n]o person of skill in the art reviewing” this disclosure would understand it to disclose “a bit that indicates whether the mobile station has power and data to accept an increase in its data rate,” id. ¶ 13.” slip op. at 28
