Reply 6. In support of its position, Petitioner cites Dr. Min’s testimony that “[i]n my opinion, a [person of ordinary skill in the art] would have understood that the ‘decision rule’ would be implemented using a decoder, as decoders typically make bit decisions.” Ex. 1003 ¶ 178; Pet. 59. Dr. Min does not cite any objective evidence in support of this view. Ex. 1003 ¶ 178. In response, Patent Owner marshals intrinsic evidence, along with Dr. Caire’s testimony based on objective supporting evidence. Prelim. Resp. 47–48; Prelim. Sur-Reply 5–6. For example, arguing that all embodiments disclosed in the ’703 patent use error-correcting coding, Patent Owner emphasizes the ’703 patent’s statement that “the [’703 patent’s] specification states that ‘[t]he invention is based on an iterative decoding solution that exploits error correction codes.’” Prelim. Sur-Reply 6 (quoting Ex. 1001, 25:27–29 (emphasis added by Patent Owner)). Patent Owner also cites the Abstract of the ’703 patent, which states that “[t]he present invention provides Turbo-decoding for joint signal demodulation based on an iterative decoding solution that exploits error correction codes.” Ex. 1001, code (57); Prelim. Sur-Reply 6. Patent Owner also cites Dr. Caire’s testimony that “any reasonable understanding of a decoder is one that implements an error correction coding approach.” Ex. 2001 ¶ 98; Prelim.

Weighing the parties’ arguments and evidence, we find Patent Owner’s more persuasive than Petitioner’s. Starting with the intrinsic evidence, Patent Owner’s citation of the ’703 patent’s repeated statements that the “invention . . . exploits error correction codes” is more persuasive than Petitioner’s argument that the ’703 patent does not disclaim other approaches. Prelim. Sur-Reply 6 (citing Ex. 1001, 25:27–29, code (57)); Prelim. Reply 6.

“In view of all the parties’ arguments and evidence, we do not find a reasonable likelihood of Petitioner prevailing on this issue. When questioning who exactly had rights to which specific inventions of Mr. McElwain’s, Petitioner glosses over the key, undisputed fact that Mr. McElwain assigned the invention of the ’703 patent to the exact same entity to which Brommer was assigned, specifically BAESI. Ex. 2012, 2; Ex. 2011, 2. Mr. McElwain did so shortly after BAE filed Mr. McElwain’s provisional application on April 14, 2003, which both parties treat as the ’703 patent’s date of invention. Ex. 2012, 2; Ex. 2013, 1; Prelim. Resp. 32; Prelim. Reply 1. This, in combination with Patent Owner’s evidence regarding Mr. McElwain’s EPIIA and BAE’s acquisition of Lockheed Martin’s Aerospace Electronics System Business, evinces that Mr. McElwain had an obligation on April 14, 2003, to assign the invention of the ’703 patent to BAESI. Exs. 2014–2016. As Patent Owner notes, Petitioner does not advance a reason that Mr. McElwain would not have been obligated on April 14, 2003, to assign the invention of the ’703 patent to BAESI, much less provide evidence that he was not so obligated. See generally Prelim. Reply; Prelim. Sur-Reply 2. In sum, weighing the parties’ arguments and evidence, we do not find that Petitioner has a reasonable likelihood of prevailing on its position that Brommer is prior art to the ’703 patent for purposes of obviousness.

“for use in conjunction with a signal separation unit, in which each received signal has associated channel transfer functions.” Ex. 1001, 12:42–45. The preamble of independent claim 9 similarly recites “a parameter estimation unit for use in conjunction with a signal separation unit for estimating channel transfer function parameters from channel transfer functions.” Id. at 14:4–7. Petitioner, however, contends that “this claim term is not part of the preamble” and that “the preamble is [only] ‘In a multi-user detection system in which interfering signals are purposely allowed to exist.’” Pet. 14. Regardless, Petitioner further contends, to the extent there is any argument that that recitation is part of the preamble, “it is limiting at least because it provides antecedent basis to the ‘parameter estimation unit’ and ‘associated channel transfer functions’ terms that are used in the remainder of the body of the claims and is ‘essential to understanding the structural limitations’ of the parameter estimation unit.” Id. Apart from arguing that the recited “parameter estimation unit” is limiting, Petitioner does not propose any id. Patent Owner does not respond to Petitioner’s contentions and also does not argue that any construction is necessary for the parameter estimation unit. See generally Prelim. Resp. As reproduced in Section II.D. above, the preamble of claim 1, in its entirety, recites, “In a multi-user detection system in which interfering signals are purposely allowed to exist, a parameter estimation unit for use in conjunction with a signal separation unit, in which each received signal has associated channel transfer functions.” Ex. 1001, 12:41–45. The preamble of claim 9 is similar. Id. at 14:3–7 (reciting “In a multi-user detection system in which interfering signals are purposely allowed to exist, a parameter estimation unit for use in conjunction with a signal separation unit for estimating channel transfer function parameters from channel transfer functions”). The body of each claim recites the elements of the recited “parameter estimation unit,” namely, “a signal processor for determining said channel transfer functions for each received signal” and “means . . . for providing uninterrupted estimates of the channel transfer function parameters on a real-time basis . . . .” The phrase “In a multi-user detection system in which interfering signals are purposely allowed to exist” provides additional context for the environment in which the parameter estimation unit is intended to operate. Whether the preamble is limiting is a question that we do not need to decide here, however. Only those claim terms that are in controversy need to be construed, and only to the extent necessary to resolve the controversy. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed. Cir. 2015).

When construing a means-plus-function limitation under § 112 ¶ 6, it is necessary first to identify the claimed function, and then to look to the specification to identify the corresponding structure for that function. In re Aoyama, 656 F.3d 1293, 1296–97 (Fed. Cir. 2011); Cardiac Pacemakers, Inc. v. St. Jude Med., Inc., 296 F.3d 1106, 1119 (Fed. Cir. 2002).

Where a Petition presents a reasonable likelihood of success as to only a small number of the challenged claims, the Board has the discretion to decline to institute review, because instituting a full review on all challenged claims may be an inefficient use of the Board’s limited resources.

Of the eighteen challenged claims, we have found that Petitioner failed to establish a reasonable likelihood of success as to sixteen of those claims. This leaves a single independent claim (claim 17) and a single dependent claim (claim 18) remaining for consideration. Even were we to conclude that Petitioner had established a reasonable likelihood of success as to claims 17 and 18, this would leave at most two claims subject to a single ground upon which such a showing had been made, out of eighteen challenged claims. Based on the particular circumstances of this case, it would be inefficient for the Board to expend resources on a full review of all eighteen challenged claims, where Petitioner has failed to establish even a reasonable likelihood of success as to the vast majority of those claims.

“Mr. Schmandt rests his opinion regarding the processing limitation on his testimony that “[a]s explained above, Coffman teaches that the conversationally-aware application associated with the determined context (‘the domain agent associated with the determined context’) is invoked to process the user’s request.” Ex. 1002 ¶ 139 (citing Ex. 1003, 37:2–4, 13:8–13, 58:9–11, 40:9–19, 30:4–10); see also Pet. 49–50 (same position citing same Coffman passages). This alleged teaching is not clearly in the cited passages of Coffman. And, although Mr. Schmandt represents that he “explained above”11 why he reads Coffman this way, he does not provide a cohesive, persuasive explanation of his reading of Coffman. Ex. 1002 ¶ 139. Instead, Mr. Schmandt’s testimony resorts significantly to conclusory statements without logical, persuasive support. See, e.g., Ex. 1002 ¶ 125 (“making clear that an application is automatically selected and carries out a request as a result of processing by the conversational system.”). Petitioner does no better.

“We agree with Patent Owner. We are not persuaded by Petitioner that it would have been obvious to a POSITA, based on the disclosures of Kennedy and Kurani-816, to store a digital title in memory 228 of processing server 102 for the purpose of record keeping. See Ex. 2013 ¶ 91. Kennedy discloses that processing server 102 includes a memory 228 for storing data used to perform its function, such as encryption keys, algorithms, and application programs. Ex. 1033 ¶ 46. Kennedy does not disclose memory 228 being a document store for record keeping of transaction messages or other transaction data. See id. In Kennedy, a private blockchain 206 stores data record 208 containing the transaction data. See e.g., id. ¶¶ 48–51; Fig. 2. Kurani-816 discloses digital titles that are specific to an asset and not to a particular financial transaction. Ex. 1034, 3:13–15. The digital titles are stored in a database at a digital title company and provided to the seller or buyer during a transaction. See e.g., id. at 6:34–9:7. Kurani-816 does not disclose transmitting the digital title to a financial transaction processing server, like processing server 102. Id. Thus, neither Kennedy nor Kurani-816 teaches transmitting documents pertaining to a financial transaction and a token corresponding to a financial transaction to identify the document to a first document store, as required by claim elements 1 and 6. For the reasons above, we are not persuaded by Petitioner that claim 1 would have been obvious to a POSITA over Kennedy and Kurani-816.” slip op. at 19

As both Kennedy and Kurani-816 were filed after August 14, 2015 (see Ex. 1033, code (22); Ex. 1034, code (22)), if the ’413 patent is entitled to priority to August 14, 2015, then neither Kennedy nor Kurani-816 is available as prior art.
