PCT ’199 does not describe the invention in enough detail to enable a person of ordinary skill in the art to conclude that the inventor possessed a frame for allocating resource for uplink (UL) multi-user (MU) transmission to one or more terminals that includes the AID field set to a value related to a first padding field, when the padding field is included in the frame. In particular, we discern no disclosure that conveys that the inventor possessed the following: (1) an AID field for the MU UL resource allocation frame is set to a value, (2) that the AID field is set to a value related to the padding field, and (3) that the AID field is set to a value related to the padding field, and conditioned on the inclusion of the AID field in the frame. Moreover, to the extent that Patent Owner’s assertions are premised on the PCT ’199’s disclosure of a preset padding being performed before the FCS field of the trigger frame and the disclosure of inserting redundant AID information prior to the FCS field of the trigger frame, we note that these disclosures are directed to two embodiments.

PCT ’199 does not provide any suggestion that the two embodiments are used together, or that the redundant AID information of one embodiment can serve as a preset padding of the other embodiment. On the record before us, we also do not agree that KR ’754 describes the invention in enough detail such that a person of ordinary skill in the art could conclude that the inventor was in possession of the invention as of the March 17, 2015 filing date of KR ’754. The disclosures of KR ’754 cited by Patent Owner to show written description support show: (1) multiplexed terminals over respective channels, (see Ex. 1008 ¶¶ 65–66, Fig. 10); (2) differing the number of AID values in the batch acknowledgment (BA) information field when the number of terminals assigned to each channel differs, setting the length of each multiplexed group ACK differently, and, if necessary, aligning the lengths of the multiplexed group ACKs based on the channel with the longest assigned BA information by adding zero padding or repeatedly inserting BA information (see Ex. 1008 ¶¶ 66–70, Fig. 11); and (3) applying the use of the AID field padding and the use of BA padding in a downlink OFDMA trigger process during multi-user downlink transmission to align the length of the trigger when the AP notifies the terminals assigned to each channel by inserting zero padding or repeating AIDs (see Ex. 1008 ¶¶ 71–72, Figs. 11–12). KR ’754 does not describe the invention in enough detail to enable a person of ordinary skill in the art to conclude that the inventor possessed a trigger frame indicating uplink transmission for one or more terminals that includes an AID field used to identify whether the trigger frame includes a padding field, and the trigger frame including the padding field when the AID field is set to a specific value. In particular, we do not discern disclosure in KR ’754 that conveys that the inventor possessed the following: (1) a trigger frame indicating uplink transmission to one or more terminals and including an AID field used to identify whether the trigger frame includes a padding field; (2) the AID field for the trigger frame is set to a specific value, and (3) that trigger frame includes the padding field when the AID field is set to a specific value. We find misplaced Patent Owner’s argument that “KR ’754’s discussion about Figure 10 and Figure 11 would have been understood [by a POSITA] as disclosing a padding method used to improve predictability and consistency trigger frame” (Prelim. Resp. 12) because: (1) it addresses uplink transmissions and not a trigger frame indicating uplink transmission to one or more terminals; (2) it does not address that the padding field is included in the trigger frame when the AID field is set to a specific value; and (3) it is unsupported attorney argument regarding the understanding of a person of ordinary skill in the art. Argument of counsel cannot take the place of objective evidence. See Gemtron Corp. v. Saint-Gobain Corp., 572 F.3d 1371, 1380 (Fed. Cir. 2009). We also find misplaced Patent Owner’s argument that “the padding discussed by KR ’754 regarding its Figure 12 embodiment is not limited to downlink transmission and would have been understood by a POSITA as also being used to schedule uplink ones” (Prelim Resp. 14) because: (1) KR ’754 does not provide any suggestion that the same technique can be used for uplink transmission trigger frames; (2) Patent Owner’s argument does not address that the padding field is included in the trigger frame when the AID field is set to a specific value; and (3) Patent Owner’s argument is unsupported attorney argument regarding the understanding of a person of ordinary skill in the art. See Gemtron, 572 F.3d at 1380. For the foregoing reasons and based on this record, for the purpose of institution, we find that the ’186 Patent is not entitled to an effective filing date earlier than April 8, 2019 and find that Kim is prior art. We note that the limitations at the heart of the written description dispute were added in an amendment filed August 9, 2020. See Ex. 1002, 214–21.

“We do not agree with Patent Owner’s arguments because they are premised on Choi’s teachings as limited to AIDs transmitted via a control frame broadcast as a TIM element.

Chu, Choi, and the testimony of Dr. Ding (Ex. 1003), we are persuaded Petitioner sets forth sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to a person of ordinary skill in the art to combine Chu’s teachings with Choi’s use of specific AID or ΔAID values as indicators of the end of meaningful data and the beginning of padding that would allow client stations to reliably determine where the useful content of the trigger frame ends and where optional padding begins, with the benefits of improved parsing efficiency, enhanced synchronization, and reduced likelihood of misinterpreting padding as data as padding.

“Petitioner argues that one of ordinary skill in the art would have found the proposed modification obvious for several reasons. Pet. 30. For instance, Petitioner argues that “Unger contains an express teaching, suggestion and/or motivation to incorporate an element such as Smith’s torsional spring into the lower and/or upper mount assemblies 308, 312 to facilitate attachment and detachment.” Id. Namely, Petitioner points to Unger’s disclosure that device mounts 308, 312 may be flexible or resilient so that device mounts 308, 312 may be bent to engage a portion of hearing protection device 108 and are then allowed to return to a normal state to secure communication device 104 to hearing protection device 108. Id. at 30–31 (quoting Ex. 1004, 6:20–37). Petitioner adds that one of ordinary skill in the art would have understood this disclosure “to teach that mount arms 308, 312 could be removable from housing 304 (e.g., as mount arm 312 is in Figure 6) and/or they could be designed to be ‘flexible’ or ‘resilient’ such that they can be manipulated,” and “that ‘resilient’ is defined as ‘bouncing or springing back into shape, position, etc. after being stretched, bent, or, esp., compressed.’” Id. at 31 (citing Ex. 1002 ¶ 117). Thus, according to Petitioner, this disclosure of Unger suggests using a torsion spring. Id. In addition, Petitioner asserts that one of ordinary skill in the art would have understood Unger’s disclosure to “suggest the use of a torsion designed to impart this functionality.” Pet. 30 (citing Ex. 1002 ¶ 118). Petitioner also asserts that one of ordinary skill in the art would have “understood that there were a limited number of ways to impart the referenced resilient or flexible ‘manipulation,’” and “would have been motivated to look to various known solutions to impart the suggested functionality, including the torsional spring mechanism of Smith that is used in a similar hearing protection device application for a similar purpose as Unger’s mounting arms (to apply a clamping force).” Id. at 32 (citing Ex. 1002 ¶¶ 120–121). Other reasons for combining the references set forth by Petitioner are the proposed modification: (1) “would have involved applying a known technique to a known device ready for improvement to yield predictable results” (Pet. 39–49 (citing Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1380 (Fed. Cir. 2023); Ex. 1002 ¶ 131)), (2) would have constituted “combining prior art elements using known methods to achieve predictable results” (id. at 40 (citing KSR Int’l Co. v.

If “the command signal is passed through to both associated ranks” and “the command signal is sent to both memory devices,” each rank must have only one memory device. Thus, we agree with Petitioner that this passage means that a rank may have only one memory device.

“We agree with Petitioner that the ’244 provisional does not provide written description support under § 112 ¶ 1 for claim 16 of the ’912 patent. There is no mention of “bank address” signals in the ’244 provisional. In order to find that “bank address” signals are present, according to Patent Owner’s arguments and the evidence presented, one would have to (1) assume at least that the ’244 provisional pertains to DDR memory modules (when there is no mention of DDR and there were other types of DRAM devices on the market) because Figure 1 suggests them by its use of chip select signals and the term “rank,” and because they were the most common at the time; (2) understand that DDR DRAMs use bank address signals according to the JEDEC standards; (3) recognize that bank address signals are not mentioned in the ’244 provisional; (4) infer that bank address signals would be included as part of the control signals (even though the other address signals are explicitly mentioned and set out separately); and (5) infer that the bank address signals are used for rank multiplication (when row/ and column/address could have been used for this purpose).

Samsung Electronics Co., Ltd., Appeal No. 23-2346, Doc. 14, page 15 (Fed. Cir. Jan. 10, 2024). In an inter partes review, a petitioner “may request to cancel as unpatentable 1 or more claims of a patent only on a ground that could be raised under section 102 or 103 and only on the basis of prior art consisting of patents or printed publications.” 35 U.S.C. § 311(b). Ellsberry is a printed publication, having been published in December 2006, as Patent Owner acknowledges. See Ex. 1037, code (43) (publication date of Dec. 7, 2006); see also PO Resp. 54 (acknowledging publication in December 2006).

Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc).

The Board denied institution because Morris was not prior art: claims 1 and 16 were entitled to the ’454 application’s priority date, so the obviousness challenge did not meet the institution threshold.

“a person of ordinary skill in the art at the time of the invention “would be a person with a B.S. degree in electrical engineering, computer engineering, or equivalent training or job experience, with two years of experience in computer networking technology, or a Master’s degree in electrical engineering, computer engineering, or other equivalent degree.” Pet. 13 (citing Ex. 1003 ¶ 47). Patent Owner indicates that it does not challenge the qualifications proposed by Petitioner for a person of ordinary skill in the art. PO Resp. 14. We find Petitioner’s proposal consistent with the level of ordinary skill in the art reflected by the prior art of record, see Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978), and, therefore, we continue to adopt Petitioner’s unopposed position as to the level of ordinary skill in the art for purposes of this decision.” slip op. at 7

“associated sessions” With respect to the limitation “associated sessions,” Patent Owner asserted that the ’669 Patent defines those sessions as those that “should not be managed independent from each another,” and continues to assert the same in its Response. PO Resp. 14–15 (quoting Ex. 1001, 7:37–38). Based on the recitations of the Specification, we construe “associated sessions” as “sessions that should not be managed independent from each other,” as proffered by Patent Owner. Ex. 1001, 7:37–38. slip op. at 8
- Prior constructionTerm construed board ownDecided for petitioner
“Patent Owner asserts that the United States District Court for the Eastern District of Texas rejected Petitioner’s proposed construction in the District Court Case, and following briefing and oral argument in that proceeding, the District Court concluded that “composition session” means “a signaling session that is separate from the associated sessions and that is for facilitating management of the associated sessions.” PO Resp. 16. Having reviewed the District Court’s determination, we do not discern a significant difference in scope between it and Petitioner’s formulation, and we, thus, adopt its construction of “composition session” in the analysis below.” slip op. at 9
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“As such, we continue to determine that Petitioner has sufficiently established that an ordinarily skilled artisan would have had a rationale to combine the teachings of Foti with RFC 3261, RFC 4566, RFC 2326, Wright, and Lloyd, and would have had a reasonable expectation of success in achieving that combination, as we determined in the Institution Decision. See Inst. Dec. 17–18. We continue to be persuaded that one of ordinary skill in the art would have consulted and utilized disclosures in the RFC references to understand and implement the protocols disclosed by Foti. We are further persuaded by Petitioner’s arguments that such skilled artisans would have had a rationale to combine the teachings of Wright and Lloyd with those of Foti for the reasons provided. Petitioner has asserted that each of the supporting references would have been used by persons of ordinary skill in the art to modify or enhance the system described in Foti for the benefits described for the proposed changes. Absent reasons the references should not be combined, we determine that the motivation proffered by the Petition is sufficient to support the combination, under the preponderance of the evidence standard.” slip op. at 16

“electriciaan” and not a “licensed electrician.” Opp. 3–4 (citing Ex. 1002, 25 ¶¶ 6–7, 32 ¶¶ 46, 48). Instead, Petitioner argues that “the disclosure lacks the term ‘licensed electrician,’ lacks a definition of ‘licensed electrician,’ and lacks an explanation of what type of electrical connection would be allowed without the assistance of a licensed electrician.” Id.; Ex. 1035 ¶¶ 76–79) (emphasis omitted). Accordingly, Petitioner argues that the original application does not support proposed substitute claims 23 and 28. See id. We are persuaded by Petitioner’s argument. The ’295 and ’447 applications describe a “skilled” electrician, not a “licensed” electrician. Patent Owner does not show that one of ordinary skill in the art would interpret these to be equivalent. Accordingly, we find that proposed substitute claims 23 and 28 adds new matter. Proposed substitute claim 24 depends from claim 23 and thus includes the same new matter.” slip op. at 63

“electrician. See id. (citing Ex. 1002, 25 ¶¶ 6–7). Petitioner’s declarant, Dr. Ducharme, attests that a “licensed electrician is an individual who has obtained a license from a regulatory authority such as a state or local government.” Ex. 1035 ¶ 85. The licensing standards set forth “differ depending upon a given industry” and “change over time.” Id. Accordingly, Petitioner asserts that “one skilled in the art is left to speculate as to what type of electrical wirings require a licensed electrician and which do not — there is no reasonable certainty of the scope of the claimed invention, as the standard requires.” Opp. 5–6 (citing Nautilus, Inc. v. Biosig Instruments, Inc., 572 U.S. 898, 901 (2014)). We are persuaded by Petitioner’s argument that proposed substitute claims 23 and 28 are indefinite. Specifically, we agree that there is no reasonable certainty as to the definition of a licensed electrician, nor how to adapt wiring for series connection without the required assistance of a licensed electrician. Accordingly, we find that proposed substitute claims 23 and 28 are indefinite. Proposed substitute claim 24 depends from claim 23 and thus includes the same indefinite limitation.” slip op. at 64
