Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed.

    “As discussed above, we agree with Petitioner that Kirchhoff discloses the use of SSL, a protocol that uses data encryption (Ex. 1005, 8:47–49). We also agree with Petitioner that Krtolica discloses the use of HTTP protocols on port 80 (Ex. 1004, 6:23–24), and does so with a goal of maintaining high network security (id. at 1:7–10, 2:33–36). As Kirchhoff discloses, and Dr. Lavian’s testimony supports, one of ordinary skill in the art would have been aware that port 443, rather than port 80, would be used for secure web connections using SSL, which includes the use of encryption, and this would have resulted in enhanced network security. See Ex. 1005, 3:38–41; Ex. 1002 ¶¶ 52, 69, 108. As Dr. Lavian testifies, SSL/TLS was the most widely deployed security protocol in the world and the well-known use of SSL in HTTPS protocol enables secure web-based e-commerce. Ex. 1002 ¶¶ 69, 108; Ex. 1035 ¶ 8; Ex. 1006, 5. And, Krtolica has a stated goal to maintain network security. Ex. 1004, 1:7–10, 2:33–37. We find this evidence provides a sufficient rational underpinning in support of obviousness for combining the teachings of Krtolica and Kirchhoff. See KSR, 550 U.S. at 418. Owner’s arguments that use of encryption in SSL was optional and adding encryption would allegedly undermine network security. Nor do we find persuasive the argument that the Petitioner’s motivation to combine based on efficiency is insufficient, because Petitioner relies on another rationale for the combination of Krtolica and Kirchhoff, that is, enhanced network security, also discussed above. We additionally do not find persuasive Patent Owner’s arguments that combining Krtolica and Kirchhoff would render the system of Krtolica unsatisfactory for its intended purpose because, as Petitioner argues, this assertion is contradicted by the state of the art at the time. See Pet. Reply 9. As discussed above, Dr. Lavian explains that there were known systems having firewalls with SSL traversal at the time of the invention. Ex. 1002 ¶¶ 53, 59–65; Ex. 1035 ¶ 20; Ex. 1014. Moreover, the ’978 patent uses encryption with firewalls using a single-port protocol, and Patent Owner does not direct us to any disclosure in that patent that indicates that the use of encryption with a single-port protocol was inventive in that the system, or that encryption had to be done in a special manner.

None of the challenged claims (nor even unchallenged claim 8) recites the claimed disabling or terminating occurs in response to the detect signal independent of other circuit conditions or in response only to the detect signal. See Ex. 1001, 12:5–14:36. For instance, independent claim 4 merely recites, “wherein the control circuit disables the switched drive control signal in response to the detect signal.” Id. at 12:49–51.

Patent Owner further directs our attention to a single sentence of deposition testimony in which Petitioner’s declarant Dr. Szepesi appears to agree with Patent Owner’s construction by stating, in the context of claim 9, that “the output signal of this first comparator disables the output pulses driving the gate of that independent of anything else.” PO Resp. 8 (citing Ex. 2003, 44:16– 45:1). Petitioner rebuts Patent Owner’s arguments by identifying additional deposition testimony and statements made in a second declaration offered by Dr. Szepesi opposing Patent Owner’s construction. Reply 2–3 (citing Ex. 1016 ¶¶ 18–21, 26–30; Ex. 2003, 43:16–45:1). For instance, immediately before the statement Patent Owner cites, Dr. Szepesi testified: Q: “So is it your opinion that an output for disabling the pulse generator must disable the pulse generator regardless of the other conditions in the circuit?” . . . A: “I don't understand your question. I said disabling the pulse generator means that the output of the pulse generator which is providing the pulses to the gate of the main switch, those pulses are disabled. That’s what it means in my opinion in this context.” Ex. 2003, 43:24–44:9. And, in his supplemental declaration, Dr. Szepesi states: As a first matter, I opined during my deposition that “an output disabling a pulse generator” means that “the output signal of this first comparator disables the output pulses driving the gate of that independent of anything else.” But, at the time of my deposition I had not done a focused claim construction analysis of the limitation “a first comparator […] having an output for disabling the pulse generator.” This is because I hadn’t anticipated there being a dispute relevant to the validity analysis in view of what I understood as the plain meaning of the language. Despite the quote that Patent Owner relied upon, I believe now that a POSITA would not understand the claim language to require the first comparator to disable the output pulses independent of anything else. This belief is consistent with my responses to the first two of three successive questions in which I was asked about “disabling the pulse generator.” It is my opinion that the operation of the disclosed embodiment requires the presence of other conditions precedent before the first comparator can disable the drive pulses and this requirement is not excluded by the claim language. Ex. 1016 ¶ 18 (emphasis added). Our reviewing court has made clear that extrinsic evidence “is generally of less significance than the intrinsic record” in matters of claim construction. Wi-LAN, Inc. v. Apple Inc., 811 F.3d 455, 462 (Fed. Cir. 2016) (citation omitted). Here, beyond competing declarant testimony, neither party has entered into the record extrinsic evidence, such as dictionary definitions or contemporaneous usage in the art, addressing the scope of “in response to.” Having considered the testimony upon which Patent Owner relies and weighing it against the claim language itself, the Specification’s disclosures set forth above, and the contrary testimony of Petitioner’s declarant, we find on balance that it does not warrant departing from the plain and ordinary meaning of “in response to” as Patent Owner urges. See In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994) (holding that an inventor may define specific terms used to describe invention, but must do so “with reasonable clarity, deliberateness, and precision”) (quoting Intellicall, Inc. v.

As discussed above, we decline to import into claim 4 a requirement that the claimed disabling must occur independent of other circuit conditions. See supra Section III.C.1. Because Patent Owner’s argument relies on a claim construction that we rejected above, we are not persuaded that Hwang fails to meet the limitations of claim 4. Rather, having reviewed the evidence cited by Petitioner, we agree with Petitioner that Hwang discloses the limitations of independent claim 4, arranged as recited in the claim. Petitioner’s analysis, as supported by the Szepesi Declaration, further demonstrates where Petitioner contends each element of dependent claims 5 and 6 is disclosed in Hwang. Pet. 21–24. Patent Owner does not dispute Petitioner’s analysis beyond the argument raised with respect to claim 4. See PO Resp. 17.

Goodrich, testified during his deposition that the records “may be records that don’t have direct impact on the registry.” Id. at 7–8. Even if Patent Owner’s characterization of Dr. Goodrich’s deposition testimony is accurate, Petitioner does not argue in the Petition or the Reply that the challenged claims do not require monitoring registry accesses. See Pet. 13–15, 21–32; Pet. Reply 1, 3–8. As such, there does not appear to be a dispute that requires claim construction. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (“[O]nly those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy.”). Nonetheless, in order to avoid any ambiguity, we provide an express construction of the phrase “records regarding processes that access the operating system registry.” We determine that the evidence supports Patent Owner’s proposed construction. The written description of the ’084 patent consistently indicates that records of processes are obtained by monitoring accesses to the operating system registry. Ex. 1001, col. 5, ll. 6–18, col. 8, ll. 9–10, col. 8, ll. 22–24, col. 13, ll. 28–31, col. 13, ll. 46–52. In addition, Petitioner acknowledges that the challenged claims require monitoring accesses to the operating system registry. Tr. 12:15–13:3. Patent Owner’s proposed construction, however, omits the claim terms “processes” and “operating system,” which are part of the phrase being construed. Ex. 1001, col. 23, ll. 32–34. Therefore, we modify Patent Owner’s proposed construction to include those terms. Specifically, we construe the phrase “records regarding processes that access the operating system registry” to mean “records regarding processes obtained by monitoring accesses to the operating system registry.”1” slip op. at 6

    “implemented function is the algorithm disclosed in the specification.” Aristocrat Techs. Austl. Party Ltd. vs. Int’l Game Tech., 521 F.3d 1328, 1333 (Fed. Cir. 2008) (quoting Harris Corp. v. Ericsson Inc., 417 F.3d 1241, 1249 (Fed. Cir. 2005)).

For the reasons set forth below, we conclude that the four steps and other ’604 patent specification portions identified by Enfish do not describe an algorithm for the recited function of “configuring memory according to a logical table.” We further conclude that Enfish has not clearly linked or associated the recited function to the four steps or the other portions of the ’604 patent specification that Enfish identifies.” slip op. at 11

Additionally, limitations are not to be read into the claims from embodiments in the specification. See In re Van Geuns, 988 F.2d 1181 at 1184. Furthermore, we agree with Microsoft that Enfish relies on insufficient extrinsic evidence for support, for example, that an OID is “immutable.” We also note that Enfish’s contentions are not commensurate with the scope of the claims because each of the independent claims recites that an OID is included “to identify” each logical row and each logical column, but does not recite using an OID to retrieve data from memory.

    “We give little weight to Dr. Hosking’s testimony with respect to the limitations in claim 34 because he does not provide an explanation or evidence as to why Dickerson’s synchronization of data in the same column across separate databases teaches reciprocal synchronization between columns in the same table. Dr. Hosking states that a person of skill in the art would be motivated to combine Chang and “the synchronization concept as taught in Dickerson in the case that similar elements were to be reciprocally synchronized.” Ex. 1022 ¶ 225. The premise of this argument is the assumption that Dickerson’s synchronization across separate databases is the same as synchronizing two logical columns reciprocally in the same database table. Dr. Hosking does not provide support for this assumption. This argument, therefore, does not sufficiently explain why mirroring data across separate databases leads to data synchronization between logical columns in the same table. Dr. Hosking’s testimony does not explain why, or how, one of ordinary skill in the art would use the database management disclosed by Chang in cooperation with the linked database elements between separate databases to achieve reciprocal synchronization “to achieve such coordination of the data” between logical columns in the same table.

Secondary considerations do not weigh into determinations regarding anticipation. Cohesive Techs., Inc. v. Waters Corp., 543 F.3d 1351, 1364 (Fed. Cir. 2008). Because we conclude that Microsoft has not shown that claims 51–53 of the ’775 patent are unpatentable for other reasons, the only claims that we need to evaluate are dependent claims 49 and 50 of the ’775 patent. Microsoft asserts that claims 49 and 50 are obvious over the combination of Visual Basic with a reference that teaches referencing objects through two-way pointers.
