    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

      “We are persuaded that our preliminary interpretation of “session” in our Decision on Institution is, at least in some respect, overly broad. Independent claims 1, 6, 7, and 10 each refer to “sessions” in plural, and independent claim 7 refers to “simultaneous” sessions. Thus, the term “session” must be understood, at least, in such a manner as to allow multiple sessions to be distinguished from one another. Although independent claim 5 does not recite “sessions” in plural, the same term should be construed consistently across all claims. Accordingly, we conclude that there must be sufficient delineation within a proper construction of “session” that separates a “session” between one client and one server and a different “session” when one of the client and server are replaced, and that separates multiple sessions from each other even between the same pair of client and server. During Oral Hearing there were extensive discussions regarding proper construction of “session.” See Tr. 7:9–22:18, 43:11–65:15, 74:21–76:13. At Oral Hearing, counsel for Petitioner agreed that “session” should be understood as communications having a recognizable beginning and a recognizable end. Id. at 10:13–16 (“Of course a session has a beginning and an end. I think that is axiomatic in a session. I think that is how Dr. Rubin defined it in his declaration”); see also id. at 12:21–13:5, Ex. 1005 ¶ 41. Patent Owner also agreed that if the construction of session is made to include a recognizable beginning and a recognizable end, that would be a proper construction for the term:” slip op. at 12

    • Novelty / Anticipation (§102) › Anticipation standard (single reference, every element)Not shown unpatentableNot shown unpatentable

      “We agree with Patent Owner that Petitioner has failed to identify what constitutes a “session” in Feinberg in accordance with a proper construction of “session.” That proper construction of “session” is set forth above and has been agreed to by the parties. Tr. 10:13–16, 53:13–54:10. We state it again here: “a set of transmitters and receivers, and the data streams that flow between them wherein each data stream flowing between the transmitters and receivers has a recognizable beginning of the data stream transmission and a recognizable end of the data stream transmission.” Petitioner identifies Feinberg’s disclosure of forwarding (shunting) received requests from the primary server to secondary servers (for purposes of load balancing) teaches the recited “communication between the main server and agent server enlists additional agent servers to support incremental secure sessions in response to maintaining performance at a desired level.” Pet. 21–23 (emphasis added). The analysis is excessively generic for the claim recitation of “incremental secure sessions.” It is uncertain what Petitioner regards as a session in Feinberg much less how it begins and how it ends. It is unexplained by Petitioner whether a request in Feinberg begins a session, or something else in Feinberg begins a session. We decline to speculate in that regard. It is Petitioner who bears the burden of proof, and who must account for all the limitations in a claim. In that regard, we note further that it is insufficient for Petitioner to present only dots that may be connected in some unspecified manner to yield the claimed invention. Instead, Petitioner must make a sufficient connection through the dots to demonstrate a full accounting of the claimed invention.” slip op. at 22

      “that the system supports “incremental secure sessions.” The Petition relies on Feinberg for disclosing such sessions, presenting the same arguments as those it presents for claim 6. See Pet. 33–34. Patent Owner argues Feinberg fails to disclose sessions for the same reasons as those that Patent Owner presented with respect to claim 6. See PO Resp. 36–37. Petitioner’s Reply asserts essentially the same arguments for claim 1 as it does for claim 6 regarding “incremental secure sessions.” Pet. Reply 17. Petitioner does not rely on Bhaskaran to alleviate the above-identified deficiency in the analysis of Feinberg with respect to claim 6. The standard for obviousness under 35 U.S.C. § 103(a) is what would have been taught or suggested to the ordinarily skilled artisan with based on the references. The key to supporting any prima facie conclusion of obviousness under 35 U.S.C. § 103 is the clear articulation of the reason(s) why the claimed invention would have been obvious and, the Court has noted that, the analysis supporting an obviousness assertion should be made explicit. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007)). A “legal determinations of obviousness, as with such determinations generally, should be based on evidence rather than on mere speculation or conjecture.” Alza Corp. v. Mylan Labs., Inc., 464 F.3d 1286, 1290 (Fed. Cir. 2006). As discussed supra, Petitioner failed to account adequately for the recited “sessions.” Therefore, Petitioner has failed to establish by a preponderance of the evidence that independent claims 1, 6, and 10 would have been obvious over Feinberg and Bhaskaran and, for the same reasons, has failed to establish claim 3, dependent from claim 1, would have been obvious over Feinberg and Bhaskaran.” slip op. at 24

    • ExcludeMotion to exclude, deniedDenied

      “Initially, we note Patent Owner’s Motion to Exclude fails to identify the portions of Dr. Rubin’s Declaration that allegedly fail to be based upon sufficient facts or data, that allegedly are the product of unreliable principles and methods, or that allegedly fail to reliably apply sound principles and methods to the facts of the case. There is no requirement for an exact or perfect match between the expert’s experience and the field of the patent. SEB S.A. v. Montgomery Ward & Co., Inc., 594 F.3d 1360, 1372–73 (Fed. Cir. 2010). Thus, Patent Owner fails to meet its burden with respect to this Motion to Exclude. See 37 C.F.R. § 42.20(c). Furthermore, regarding the objections under FRE 702, we note that under 37 C.F.R. § 42.65(a), “[e]xpert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.” Consequently, this objection more properly goes to the weight to be given Dr. Rubin’s testimony, and not to its admissibility. In any event, Patent Owner’s argument, that Petitioner did not explain the evidentiary weight or standard that was applied by Dr. Rubin, is misplaced. We note that Dr. Rubin is an expert witness, not a fact finder or a tribunal making fact findings. Dr. Rubin need only provide his opinion and, preferably, also provide the underlying reasoning, inclusive of data and facts, in support of his opinion. For the above reasons, Patent Owner’s Motion to Exclude is denied.” slip op. at 27

In that regard, we note further that it is insufficient for Petitioner to present only dots that may be connected in some unspecified manner to yield the claimed invention. Instead, Petitioner must make a sufficient connection through the dots to demonstrate a full accounting of the claimed invention. Petitioner had ample notice of the possibility of a narrower interpretation of “session.” See PO Resp. 7–11, 23–24. Indeed, Petitioner responded to that possibility by referring to its own expert’s testimony that the beginning and end of a session may be signified in a variety of forms. Pet. Reply 2. See Genzyme Therapeutic Prod. Ltd. P’ship v. Biomarin Pharm. Inc., 825 F.3d 1360, 1367 (Fed. Cir. 2016) (“The critical question for compliance with the APA and due process is whether [the parties] received ‘adequate notice of the issues that would be considered, and ultimately resolved, at [the] hearing’”) (internal citation omitted). Nevertheless, Petitioner’s Reply still does not specifically identify a “session” within Feinberg that accounts for what constitutes a session in Feinberg, including when it begins and ends. Claim 10 recites, in pertinent part, “sharing spare CPU cycles of the computer network for encrypting and decrypting communication to provide N simultaneous secure session[s] among said network of computers.” Petitioner’s analysis with respect to the recitation of “N simultaneous secure session[s]” is deficient for the same reasons we discussed above with respect to the recitation of “incremental secure sessions” in claim 6. For the above reasons, we are not persuaded Petitioner has established, by a preponderance of the evidence, that claims 6 and 10 are anticipated by Feinberg.” slip op. at 22
