“Fintiv, we agree that it indicates that this factor weighs in favor of discretionary denial because the trial date is scheduled to occur before the final written decision deadline. However, the trial date here is closer to the deadline for the final written decision, with only a two-month difference here rather than the six-month difference in Fintiv, which increases the possibility here that any unforeseen delay in the district court proceeding could cause the order of those two events to reverse. Fintiv at 9 (“If the court’s trial date is at or around the same time as the projected statutory deadline . . . the decision whether to institute will likely implicate other factors.”).

“access switches on the second port.” Ex. 1001, claim 5. We find that Petitioner has not provided sufficient information for us to find a reasonable likelihood that Gai teaches or suggests dependent claims 5 and 17 at this time. Dependent claim 17 is similar to claim 5, but depends on claim 16 (which in turn depends on independent claim 13), adding “wherein the protocol processor is adapted to update the entries in the database to point to the second access port before receiving the communication traffic from the one or more access switches on the second port.” Id. at claim 17. These claims both require the switch implementing the method for rapid recovery, such as switch 124 in Petitioner’s example discussed above, to update its filtering database before receiving communication traffic from access switches, such as access switches 115 and 116 in Petitioner’s example. Pet. 58. That effectively means that switch 124 must update its database immediately upon transitioning to the new port either before or at the same time it transmits dummy messages to the access switches. So this differs from the analysis for claim 4 because allowing the corresponding entry in the filtering database to time out will not be sufficient to ensure that the entries will be updated before receiving communication traffic from one of the access switches. There is no express disclosure from the portions of Gai cited by Petitioner of immediately updating the database on the switch implementing the method. Pet. 57–58, 94; Ex. 1005, 2:30–41, 5:36–39, 5:54–56, 12:62– 65. Based on the current record, we are also not persuaded by Petitioner’s declarant’s explanation of why Gai allegedly teaches or suggests this limitation. In the section addressing dependent claim 5, Dr. Houh asserts that: are transmitted before any communication traffic is received by the switch. As I discuss in Section VIII.A.5.ii, the filtering database is updated before transmitting the dummy messages. Accordingly, a POSITA would have understood that the database entries would have been updated before receiving any communication traffic from the access switches. Ex. 1003 ¶ 139. However, Section VIII.A.5.ii of Dr. Houh’s declaration relates to dependent claim 4 which does not have any timing requirement, and the citations to Gai there do not describe that the switch first updates its filtering database before sending the dummy message.12 Id. ¶¶ 133–136. Therefore, the conclusory and unsupported assertions that Gai teaches or suggests this limitation, or renders it obvious to a POSITA, do not persuade us that Petitioner has shown a reasonable likelihood of prevailing on these claims, at least at this stage of the proceeding.” slip op. at 58

“Id. Therefore, after a failure and switchover, edge switch 124 transmits dummy traffic to access switch 116 over the second link. Id. Based on the current record, we agree that this example is at least suggested by Gai’s teaching that “the method and apparatus manifests, in part, as a series of novel commands that may be entered at the devices. The devices, moreover, may be classified as either access switches or backbone switches.” Ex. 1005, 6:6–9. Switch 124 is a backbone switch because it interconnects at least access switches 114–116, and, according to Gai, the invention can be implemented on that switch by entering the corresponding commands on it. Id. The rest of the example, whereby ports are switched based on a failure and dummy traffic that is transmitted to the access switches updates their filtering databases, also follows Gai’s teaching. Pet. 39–46; Ex. 1005, 5:35– 6:12. Patent Owner responds to this argument by asserting that “Gai itself never describes backbone switch 124 in such a way,” disputing it could transmit dummy traffic to access switch 116 over the second link. Prelim. Resp. 10–11. Rather, according to Patent Owner, “Gai clearly explains that such an action is in response to a port failure in access switch 114, not in teaching to the preferred embodiment that describes the failure occurring at switch 114, which we do not find warranted in view of the general teaching from Gai discussed above saying the invention can also be implemented on backbone switches.

“on May 8, 2024 (see 35 U.S.C. § 314(b)(1)), and none of the relevant deadlines for fact discovery or expert discovery, or the date of the scheduled Markman hearing, will have passed by that date. As described by Petitioner, fact and expert discovery do not close until next year, the parties have not yet exchanged preliminary claim constructions, and the Markman hearing is not scheduled until December 4, 2024, approximately four months after our deadline for this decision. See Pet. 83. We also find that Petitioner’s diligence in filing the Petition only about a month after receiving Patent Owner’s infringement contentions, and only four months after the filing of the original complaint, supports this factor weighing more strongly against exercising our discretion to deny the Petition. See id. at 82. Accordingly, in view of the parties’ respective arguments, we find that factor 3 weighs strongly against discretionary denial. 4. Overlapping Issues with the Parallel Proceeding Under this factor, Petitioner stipulates that “[i]f the Board institutes trial, Petitioner will cease asserting in the co-pending litigation the combination of references on which trial is instituted for the claims, to the extent Petitioner even asserts the same combination in the district court.” Pet. 83. We find that this stipulation “mitigates to some degree the concerns of duplicative efforts between the district court and the Board, as well as concerns for potentially conflicting decisions.” Sand at 12. More specifically, if we institute, then by stipulation the court in the Cisco litigation will not have to determine whether the challenged claims of the ’279 patent would have been obvious in view of Kovvali, Kalman, Masters, and RFC 2892, and therefore the risk of inconsistent results is also reduced. against discretionary denial because the stipulation is limited in nature.10 Prelim.

“Decision below, Petitioner relies on Kovvali alone as teaching all but two steps recited in independent claim 1, and Petitioner similarly relies on Kovvali alone as teaching all but two limitations of independent claim 15. See Pet. 26–50, 63–64. For those additional steps and limitations, Petitioner relies on combined teachings of Kovvali and Kalman. See id. at 42–47. As Petitioner points out and Patent Owner acknowledges, however, Kovvali was not previously presented to the Office during prosecution of the application for the ’279 patent. See id. at 80; Prelim. Resp. 26. Moreover, notwithstanding Patent Owner’s assertion that Drake has “similar[ities] to how Petitioner characterizes Kovvali,” Patent Owner identifies only that “Drake teaches a ‘management system for local area networks’ that features an ‘allocator,’ which determined ‘if requested facilities are available, and if so, reserves these facilities for the requesting station.’” Prelim. Resp. 26 (citing Ex. 2003, code (57)). In contrast, Petitioner’s reliance on Kovvali goes significantly beyond such high-level generalizations, providing a detailed mapping of Kovvali’s teachings to, for limitations [15.1]–[15.5] and [15.8] of independent claim 15, as well as to the additional limitations recited in each of dependent claims 2, 5, 11–14, and 18, with supporting testimony from Dr. Mir’s declaration.

Notably, Patent Owner does not expressly contest Petitioner’s arguments with respect to those limitations at this stage of the proceeding. See generally Prelim. Resp.

Accordingly, on this record and after taking into account Becton, Dickinson factors (a), (b), and (d), cited by Advanced Bionics as relevant to the first part of the two-part framework set forth therein (see Advanced Bionics at 9–10), we are not persuaded that the same or substantially the same art previously was presented to the Office or that the same or substantially the same arguments previously were presented to the Office.

Although we agree that the respective articulations are “somewhat different,” they are generally similar, and our Decision does not depend on nuanced distinctions regarding the level of ordinary skill. Indeed, Dr. Goodrich describes his proposed articulation as “approximate,” such that “more work experience could compensate for less education or more education could compensate for less work experience.” Ex. 2007 ¶ 50. Because we find Petitioner’s proposal reasonable, consistent with the level of skill reflected by the prior art, and supported by Dr. Freedman’s testimony, we adopt it for this Decision.

“We agree with Patent Owner’s contention that the emphasized sentence defines the term “content-related.” See PO Resp. 15–16 (Patent Owner arguing that “[t]here are thus three strong indications of lexicography: (1) ‘content-related’ is set off by quotation marks; (2) the patentee used the word ‘is’ to describe the term ‘content-related’; and (3) the patentee states what ‘content-related’ is ‘understood to mean.’” Nor does Petitioner disagree that the sentence is definitional. See Tr. 8:15–16 (referring to the “term content-related as it’s defined in the specification”). Indeed, in the Starz litigation, the district court also treated the sentence as definitional, a fact that we find significant as a matter of comity. See Ex. 1018, 111:24–112:1 (district court judge stating at Markman hearing, “I’m going to adopt . . . the express definition provided in the specification”). But like the district court, we discern insufficient reason to adopt the additional gloss that Patent Owner seeks to apply to the definition of “content-related.” That is, Patent Owner proposes that we additionally construe the phrase “syntactical meaning” within the definitional statement to arrive at Patent Owner’s proposed construction. PO Resp. 16–20. According to Patent Owner, “[t]he specification makes clear, through its use of consistent and repeated examples, that ‘syntactical meaning’ requires a specific relationship between the data segments within a data file: succeeding data segments within a data file must be ordered so as to present the content in its intended sequence when rendered.” Id. at 17 (citing VirnetX Inc. v. Cisco Sys., Inc., 767 F.3d 1308, 1317–19 (Fed. Cir. 2014); Alloc, Inc. v. ITC, 342 F.3d 1361, 1368–71 (Fed. Cir. 2003)). Patent Owner adds that the claims, the context provided by the problems solved by the ’794 patent, and the cross-examination testimony of Petitioner’s expert, Dr. Freedman, all support this additional aspect of Patent Owner’s proposed construction. Id. at 18–20. Relying on additional direct testimony by Dr. Freedman, Petitioner counters this position as “improperly import[ing] limitations from the specification that are not required by the claims” and “render[ing] other portions of claim 1 superfluous.” Reply 3 (citing Ex. 1016 ¶ 22); see Tr. 10:18–20 (Petitioner explaining at oral hearing that “the syntax information is simply just identification information which is used to find out what the order of the files is. But the identification information does not by itself indicate the order. It’s just an identifier.”). We agree with Petitioner that it would be imprudent to adopt Patent Owner’s additional gloss because, “[w]hile claims must be construed in light of the specification, . . . limitations from the specification are not to be read into the claims, . . . for ‘[i]t is the claims that measure the invention.’” Golight, Inc. v.

It is apparent that the Applicant for the ’794 patent understood how to define terminology recited in the claims, but chose to limit its definition of “content-related” in terms of the broader phrase “syntactical meaning” rather than through narrower specific reference to presentation order. In addition, claims 1 and 9 already specify “sequentially outputting the first and second data segments according to their chronological sequence,” which supports Petitioner’s observation that requiring an additional sequential order to “content-related . . . data segments” renders other portions of claim 1 superfluous.

As such, a statement during prosecution qualifies as a disavowal of claim scope only if it is “so clear as to show reasonable clarity and deliberateness” and “so unmistakable as to be unambiguous evidence of disclaimer.” Id. at 1325 (citations omitted). “Consequently, for prosecution disclaimer to attach, [Federal Circuit] precedent requires that the alleged disavowing actions or statements made during prosecution be both clear and unmistakable.” Id. at 1325–26. “The party seeking to invoke prosecution history disclaimer bears the burden of proving the existence of a clear and unmistakable disclaimer that would have been evident to one skilled in the art.” Mass.

“We agree with Petitioner’s contention that “memory module” is not limited to “main memory modules . . . designed to connect to the primary memory controller.” See Reply 2. The ’054 patent states In certain embodiments, the device contains a high density Flash memory with a low density DRAM, wherein the DRAM is used as a data buffer for read/write operation. The Flash serves as the main memory. Ex. 1001, 11:3–6 (emphases added). This is the only mention of “main memory” in the ’054 patent. That the Flash memory serves as “main memory” in “certain embodiments” implies that there may be other embodiments in which this is not the case. Accordingly, we agree with Petitioner that the term “memory module” is not limited to “main memory modules . . . designed to connect to the primary memory controller.” We agree with Patent Owner that the “memory module” includes structure to connect with a “host system” including its memory controller. See, e.g., Ex. 1001, code (57), 12:52–59. The claims do not mention a “memory controller,” but they do mention that the “memory module” has an “interface” to connect with a “host system.” Ex. 1001, 38:20–25 (claim 1), 39:63–65 (claim 16), 41:6–8 (claim 24). That the “memory module” has structure for connecting to the host system’s memory controller may thus be implied from the claims. We agree with Petitioner that the District Court’s determination was that the preambles (presumably of claims 1, 4, 6, 11, 16 and 25) are limiting. Ex. 2032, 35. To the extent that the District Court’s determination construed “memory module” to include structure necessary to connect to a memory controller, our construction of “memory module” is consistent.” slip op. at 16

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“conversion for double-rank DIMMs can be accommodated with a form factor design of approximately about one square inch (both sides of the printed circuit board).” Ex. 1023 ¶ 13. Thus, Harris indicates that the VRM circuitry to generate two regulated voltages can fit within this space. Patent Owner argues that Petitioner’s evidence shows that each ADP1821 converter package would be about 0.193 by 0.236 inches. Sur-Reply 12 (citing Ex. 1078, 20–23). This means three ADP1821 converters would occupy about 40% of the available space. Patent Owner does not demonstrate that the remaining 60% of available space would have been insufficient to accommodate the additional components required for three voltage converters. Id. at 12–13. In any case, we do not view Harris’s disclosure of “approximately about one square inch” to limit the applicability of its teachings to a person of ordinary skill in the art. In the same paragraph, Harris states that the form factor “may be suitably modified.” Ex. 1023 ¶ 13. Patent Owner further argues that “independent voltage sources for different voltages would require specific control circuitry to delay and more precisely control each voltage source’s ramping rate, adding complexity and cost without commensurate benefits.” Sur-Reply 14 (citing Ex. 2061 ¶ 90). However, Dr. Wolfe states that it is simpler to use multiple regulators for multiple voltages since a single regulator that generates multiple voltages is more complicated than multiple regulators. Ex. 2060, 53:16–54:14, 89:1–21, cited in Reply 14. Dr. Wolfe further indicates that buck converters can be in some applications “extremely small.” Ex. 2060, 89:11–15. Dr. Wolfe further testifies that multiple smaller converters may be less costly than a larger single converter because of component costs, separated spaces available for converters on circuit board, and other “ordinary engineering factors.” Id. at 45:21–46:10. Although Patent Owner may be correct that individual control of multiple voltage regulators would have required additional control circuitry, this does not meaningfully undermine the benefits that Petitioner mentions including permitting power sequencing, independent control of voltages, improved efficiency without generating excess heat or requiring cooling devices, and saving power. Pet. 29–30 (citing id. at 14–19; Ex. 1028, 17–20; Ex. 1026, 2–3, 9; Ex. 1028, 30–32; Ex. 1040, 1, 23–24 (Figs. 22–25); Ex. 1041, 1, 13; Ex. 1048, 3; Ex. 1058, 5; Ex. 1059, 5:23–30; Ex. 1062, 11, 13; Ex. 1064 ¶ 101; Ex. 1003 ¶¶ 240, 255). Dr. Wolfe testified that, in at least some circumstances, multiple converters may be less complicated, less costly, and take up less space. Ex. 2060, 45:21–46:10, 89:11–15. Patent Owner’s argument that a single converter generating multiple voltages would be better in some circumstances does not negate that Petitioner’s proposed use of multiple converters for multiple voltages would have been preferred in other circumstances that a person of ordinary skill in the art would have recognized. See Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 800 (Fed. Cir. 2021) (“Our caselaw is clear. It’s not necessary to show that a combination is ‘the best option, only that it be a suitable option.’” quoting PAR Pharm., Inc. v. TWI Pharms., Inc., 773 F.3d 1186, 1197–98 (Fed. Cir. 2014)).
