      “question, based on factual findings. VidStream, 981 F.3d at 1063–64. Moreover, public accessibility is the touchstone in determining whether a reference is a printed publication and such depends on whether the reference was available to interested, ordinarily skilled persons exercising reasonable diligence, which is determined on a case-by-case basis. Id. at 1065. Particularly pertinent here is that “[w]hen there is an established publisher there is a presumption of public accessibility as of the publication date.” Id. Hulu (which cites VidStream on this issue) concerned, inter alia, whether certain asserted references were shown to be publicly available and could be considered as prior art. Hulu, 2021 WL 487622. Hulu holds that, although testimonial evidence is one way to prove public accessibility, there are also a variety of hallmarks of publication and other evidence that may be considered as a totality of the evidence to determine if an asserted reference was publicly accessible and prior art. Id. at *10–13, 21. Facts to be considered in analyzing the issue, other than testimonial evidence, include, for example, whether there is an established publisher, a copyright date/notice, other publication-related dates (impression, printing, etc.), an ISBN number, citations to the reference before (and to a lesser degree, after) the priority date at issue corroborating its availability and/or that the publisher was established, and whether the reference’s “purpose of publishing . . . was ‘dialogue with an intended audience.’” Id. at *10–21 (citing Valve Corp. v.

Anascape, Ltd. v. Nintendo of Am. Inc., 601 F.3d 1333, 1337 (Fed. Cir. 2010). To satisfy the written description requirement, “a prior application itself must describe an invention, and do so in sufficient detail that one skilled in the art can clearly conclude that the inventor invented the claimed invention as of the filing date sought.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 1997); see also VasCath v. Mahurkar, 935 F.2d 1555, 1563–64 (Fed.

Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1352 (Fed. Cir. 2010) (en banc) (“[I]t is the specification itself that must demonstrate possession.”). On the record before us, we do not agree that the ’171 Patent is entitled to a filing date earlier than Jan. 11, 2021. In particular, we do not agree that PCT ’199 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 4, 2016 filing date. The disclosures of PCT ’199 cited by Patent Owner to show written description support show: (1) transmission packets for multi-user uplink data, which includes padding such that multi-user upstream data transfers from each resource terminate at the same time (see Ex. 1012 ¶¶ 17–21); (2) performing padding on a trigger frame that triggers multi-user simultaneous transmission, where the trigger frame includes AID information of the performing preset padding before the FCS field of the trigger frame according to one embodiment (see Ex. 1012 ¶ 136, Fig. 20); and (4) inserting redundant AID information prior to the FCS field of the trigger frame, according to another embodiment (see Ex. 1012 ¶ 136, Fig. 20). 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. See Ex. 1012 ¶ 136, Fig. 20. 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.” slip op. at 16

Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1352 (Fed. Cir. 2010) (en banc) (“[I]t is the specification itself that must demonstrate possession.”). On the record before us, we do not agree that the ’186 Patent is entitled to a filing date earlier than April 8, 2019. In particular, we do not agree that PCT ’199 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 4, 2016 filing date.

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 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 discern no disclosure 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.

See Ex. 1012 ¶ 136, Fig. 20. 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. In further briefing, the parties should address the respective burdens of production and persuasion for establishing that the ’186 Patent is entitled to an earlier” slip op. at 16

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

      “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. A prior art “reference must be considered for everything it teaches by way of technology and is not limited to the particular invention it is describing and attempting to protect.” EWP Corp. v. Reliance Universal Inc., 755 F.2d 898, 907 (Fed. Cir. 1985) (emphasis omitted). 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. See Pet. 46–48 (citing Ex. 1003 ¶¶ 150–156; Ex. 1015 ¶ 93; Ex. 1016 ¶¶ 24, 184), 61–62 (citing Ex. 1003 ¶¶ 157–163, Pet. 45–48); KSR, 550 U.S. at 418.” slip op. at 29

      “These two proposed definitions of the ordinarily skilled artisan share many consistencies, for example, the types of degrees and experience such a person would have had, but differ in the number of years of experience. Petitioner proposes the ordinarily skilled artisan would have had at least five years of experience and Patent Owner proposes at least three years (which would necessarily include five years, too). Patent Owner also proposes that the ordinarily skilled artisan would have consulted a dentist, oral surgeon, prosthodontist, or periodontist with experience in dental implants and prosthetics. At this point, we find little meaningful difference between the two proposed definitions.

      “Here, the first claim limitation at issue is broad, i.e., different thread pattern/profile between a definite and a temporary screw, and the Specification’s and priority applications’ disclosure is narrow and specific, asymmetric buttress style threads in a temporary screw and symmetrical threads in a definite screw (are different). Any apparent predictability in or maturity of the relevant field here must be contrasted with the fact that the Specification, considering the ’992 patent itself or any of the identified priority applications, never once even discusses the (claimed) concept of specifically differing the thread style between a temporary and a definitive screw. Any differences in thread style are not called out by the disclosure, but are described and can be discerned only in relation to the respective threads’ functionality, i.e., Fig. 75’s temporary screw 190 has buttress-style threading so it can be pulled out rather than unscrewed from the abutment; Fig. 9’s definitive screw 75 has male threads that fill the female threads of the abutment 8 for a secure permanent engagement. Ex. 1001, 15:23–30, 21:25–44, 23:3–36; Ex. 1012, 97–98, Figs. 9, 75. And, although it is possible for a single disclosed species to provide written description support for a claimed genus, “a sufficient description of a genus . . . requires the disclosure of either a representative number of species falling within the scope of the genus or structural features common to the members of the genus so that one of skill in the art can ‘visualize or recognize’ the members of the genus.” Ariad, 598 F.3d at 1350; see also Synthes USA, LLC v.

That does not appear to be the case here—the present record does not support that the described asymmetrical buttress, serrated style of different temporary screw threading (relative to that of the definitive screw and regardless of the direction of the threads for rotation) is sufficiently representative of the genus’s “different” thread patterns/profiles.

      “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.

Regeneron Pharms., Inc. v. Mylan Pharms. Inc., 127 F.4th 896, 914 (Fed. Cir. 2025); Ariad, 598 F.3d at 1351. In this case, Table A of the ’935 provisional discloses a list of CH3 domain interface residues and identifies, for each interface residue in heavy chain A, the contacting residue in the corresponding chain B. Ex. 1030, 17, Table A. Table A does not, however, describe any particular substitutions or pairs of substitutions that should be made to the CH3 domains. See, e.g., Pet. 28 (citing Ex. 1002 ¶¶ 109–119). Table 7 of the ’935 provisional does identify specific amino acid substitutions in CH3 domains, including substitutions resulting in a positively charged residue at position 364 (e.g., S364K) and a negatively charged residue (e.g., L368D) at position 368. Ex. 1030, 52, Table 7. Patent Owner argues that this table “discloses specific positions for ‘identification of novel charge pair mutants.’” Prelim. Resp. 13 (citing Ex. 2010 ¶ 48). As Petitioner points out, however, while Example 13 of the ’935 provisional relates to identification of novel charge pair mutants, Table 7 itself was only a “first step” in this identification process. Ex. 1030, 51:6–17. In this step, “many interface contact residues in the IgG CH3 domain were scanned one by one or in groups for substitutions that would result in repulsion of 35 identical heavy chains” so that identified substitutions can then be used to generate antibodies “by engineering matched pairs of CH3 residues in one or more IgG heavy chains – CH3 regions” in follow up experiments. Id. Accordingly, Table 7 does not appear to describe heterodimer combinations, such as those that would result from a pairing of chains with different substitutions. Pet. 29–30 (citing, e.g., Ex. 1002 ¶¶ 111–118). As Petitioner further points out, the follow up experiments testing the matched pairs of CH3 residues did not include paired substitutions at positions 364 and 368. Id. at 29–31. Patent Owner points to disclosure in the ’935 provisional describing, as a distinguishing feature of its invention, the substitution of non-charged or neutral amino acids in wildtype CH3 with charged residues, which according to the ’935 provisional has the “advantage that at least one additional charge-charge interaction in the CH3 interface is created.” Prelim. Resp. 12 (citing, e.g., Ex. 2010 ¶¶ 42–48). For the same reasons discussed above, Petitioner has sufficiently established, for purposes of institution, that such disclosure would not reasonably convey to an ordinarily skilled artisan that the inventors had possession of the entire genus of heterodimeric antibodies comprising CH3 domains wherein a non-charged amino acid is replaced with a charged residue so as to create an additional charge-charge interaction in the CH3 interface. In this regard, we also note that “a description that merely renders the invention obvious does not satisfy the [written description] requirement.” Ariad, 598 F.3d at 1352.” slip op. at 34

Having considered the evidence of record at this preliminary stage of the proceeding, and for the reasons set forth below, we are persuaded that Petitioner has shown sufficiently, for purposes of institution, that the ’935 provisional does not provide adequate written description support for claim 1 of the ’859 patent and that, accordingly, Desjarlais and Moore qualify as prior art to that claim.

      “The ’859 patent does not provide an explicit definition of “immunoglobulin class.” Nevertheless, we do not construe that term to require “two heavy chains with four domains, VH, CH1, CH2, and CH3, and two Fab arms.” As an initial matter, the Specification teaches that antibodies include, 16 e.g., IgE and IgM — which have an additional CH4 domain in their heavy chains — as well as functional derivatives and/or fragments of known antibody isotypes. Ex. 1001, 11:44–48. Patent Owner’s proposed construction, which limits antibodies to those having two Fab arms and “two heavy chains with four domains, VH, CH1, CH2, and CH3,” excludes these embodiments and cannot be correct. Moreover, the ’859 patent defines antibody as containing “one or more domains” that bind an epitope on an antigen. Ex. 1001, 11:39–44. Thus, an antibody does not require two Fab arms as in a native immunoglobulin molecule.12 The ’859 patent also describes a preferred embodiment as “Ig-like molecules.” Id. at 11:49–52. Thus, we look to the definition of “Ig-like molecule” in the ’859 patent, i.e., “a proteinaceous molecule that possesses at least one immunoglobulin (Ig) domain,” to inform our understanding of the phrase “immunoglobulin class of proteins.” Ex. 1001, 11:4–6. Accordingly, we further construe “immunoglobulin class of proteins” to mean proteinaceous molecules comprising at least one domain that is derived from or shares sequence homology with an immunoglobulin domain.” slip op. at 16

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side.
