“B. Level of Ordinary Skill in the Art Petitioner contends that [A] person of ordinary skill in the art (“POSITA”) would have had a Bachelor’s degree in electrical engineering, computer engineering, computer science, or a related field, and at least 3 years of experience in the research, design or development of wireless communication devices, systems, and/or networks, or the equivalent. Pet. 3 (citing Ex. 1003 ¶ 26). Petitioner further contends that “[i]ncreased educational experience can make up for less work experience, and vice versa.” Id. Patent Owner objects to Petitioner’s proposed level of ordinary skill in the art only “[t]o the extent that Petitioner requires [] the required experience and/or education level to be acquired by December 24, 2015.” Prelim. Resp. 8. Determining the level of ordinary skill in the art involves various factors, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (citation omitted). The prior art of record also reflects the level of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). For purposes of this institution decision, with the exception of the openended language “at least,” we adopt the assessment offered by Petitioner.11 11 No matter how designated in this decision, any determination (except our determination to institute trial) is preliminary and non-binding. We wish to have the full record as developed during trial before rendering any binding determination, finding, or conclusion. It is not materially disputed by the Patent Owner and is consistent with the ’595 patent and the asserted prior art.” slip op. at 9

See Pet. 1. We determine that the preamble of claim 7 is not limiting because it does not recite essential steps or structure and is not necessary to give life, meaning, and vitality to the claim. See Shoes by Firebug LLC v. Stride Rite Children’s Group, LLC, 962 F.3d 1362, 1367 (Fed. Cir. 2020). 14 Petitioner provides parallel citations to Exhibit 1006, the earliest provisional application to which Josiam claims priority (see Ex. 1005, code (60), in order to show that “the relevant subject matter relied upon herein is fully supported by respective provisional applications filed before the [filing date (December 24, 2015) of the earliest foreign application to which the ’595 patent claims priority (see Ex. 1001, code (30)].” Pet. 2. At least at this stage, there is no dispute between the parties as to whether Josiam or the ’595 patent are entitled to the claimed priority. See Prelim. Resp. 1 fn.1, 12 fn. 2. Therefore, unless deemed necessary to Petitioner’s showing, we do not include references to the Petition’s citations to Exhibit 1006 or discussion of Exhibit 1006 in our analysis.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundInstituted
“combination of the disclosures of Chen and Wu and articulates reasons why a skilled artisan would be motivated to combine the relevant teachings of Chen and Wu. See Pet. 42–85. This challenge to the patentability of the claims of the ’595 patent (Ground 2 of the Petition) is detailed and supported by the cited evidence. With regard to this ground and the asserted combination of art, Patent Owner argues that “[s]imilar to Grounds 1A and 1B, Chen and Wu do not show that ‘the bandwidth field of HE-SIG-A is used to obtain information of the unassigned resource unit’ as both the bandwidth field in HE-SIG-A and a subfield in HESIG-B need to be used for explicitly indicating the unassigned resource unit.” Prelim. Resp. 15. The quoted passage is limitation 7.5 and the “explicitly indicat[ing]” element is in limitation 7.7.16 See Ex. 1001, 54:3–4, 54:9–12; see also Pet. vii (showing claim 7 with limitations numbered and labeled). Thus, Patent Owner disputes the same limitations with a similar argument as for the earlier grounds in disputing the showing in the Petition for this ground. With regard to the disputed limitations, the Petition provides that, from a combination of the teachings and suggestions of Chen and Wu, a skilled artisan would understand that “the bandwidth field of HE-SIG-A indicates where in the overall bandwidth the non-allocated RU is located by defining the number of 20MHz channels and the arrangement and length of the HE-SIG-B content channels.” Pet. 60 (citing Ex. 1003 ¶ 178). The Declaration of Dr. Buehrer provides: 16 Limitation 7.7 recites: “the unassigned resource unit is explicitly indicated with the information of the unassigned resource unit based on the bandwidth field and the at least one subfield.” Ex. 1001, 54:9–12; Pet. vii (emphasis added). 178. Chen-Wu renders obvious using the bandwidth field of HE-SIG-A to obtain the information of the unassigned resource unit. As one example, a POSITA would have understood the Chen-Wu combination as rendering obvious that RU non-allocation information in HE-SIG-B indicates the location of a non-allocated RU within a 20MHz channel, while the bandwidth field of HE-SIG-A indicates where in the overall bandwidth the non-allocated RU is located by defining the number of 20MHz channels and the arrangement and length of the HE-SIG-B content channels. SAMSUNG-1008, [0101], [0098]; SAMSUNG-1009, [0036]; SAMSUNG-1010, 10. 179. Chen teaches that “RU allocation may be determined based at least in part on the PAID, channel bandwidth, and the HE-SIG-B.” SAMSUNG-1008, [0101], [0098]. I note that the Applicant did not dispute the Examiner’s finding that Chen teaches this limitation. See SAMSUNG- 1002, 68, 102 (citing SAMSUNG-1008, [0093], [0098], [0103], Fig. 14). 180. Moreover, Wu teaches “a fixed format common field in the HE-SIGB is defined for each operation bandwidth. Therefore, the length and format of the common field are predefined [based on the bandwidth]. In this approach, there is no [additional] indication needed in the HE-SIG-A.” SAMSUNG-1009, [0036]; SAMSUNG-1010, 10. As I explained above for [7.2] and [7.4], a POSITA would have understood Chen’s HE-SIG-A as including a bandwidth field that indicates the operation bandwidth of the PPDU. See [7.2], [7.4]. 181. For example, if the bandwidth field of HE-SIG-A indicates a PPDU bandwidth of 80 MHz, and the resource unit allocation field of the common field of HE-SIG-B indicates that the 20 MHz corresponding to the fourth channel is partitioned into 106, 26, and 106-tone resource units, the resource unit non-allocation information may indicate that the 26-tone resource unit is not assigned to any user through, e.g., a bitmap per Chen. SAMSUNG-1008, [0075], [0089]-[0093], Figs. 4, 12- 14; SAMSUNG-1009, [0035]-[0043], Figs. 2-4; SAMSUNG- 1010, 2-6, 10-14. Ex. 1003 ¶¶ 178–181 (alterations in original) (footnote omitted). We determine that this testimony of Dr. Buehrer is supported and reasonable and sufficiently persuasive and credible to support institution. We also note that Patent Owner does not, at least at this stage, provide any contradictory expert testimony.17 We have considered Patent Owner’s arguments relating to the disputed limitations and this ground and found them not to be as well-supported as the Petitioner’s showing for essentially the same reasons as discussed above with regard to Ground 1A. Based on the current record, we determine that there is a reasonable likelihood that Petitioner will prevail with respect to the unpatentability of claims 1–12 of the ’595 patent based on a combination of the teachings and suggestions of Chen and Wu.” slip op. at 29

“For purposes of this Decision, we adopt the definition of the level of ordinary skill in the art proposed by Petitioner. As to the inclusion of physics in Petitioner’s definition, Dr. Singhose (a professor of mechanical engineering) testifies as to why undergraduate mechanical engineering degree holders would have the requisite knowledge here, but does not testify that undergraduate physics degree holders would not. See Singhose Decl. ¶¶ 2, 27, 28. In addition, Patent Owner and Dr. Singhose require “a four-year degree in mechanical engineering or a closely related field,” but fail to identify what fields are “closely related.” See Prelim. Resp. 11; Singhose Decl. ¶ 27. Based on the Morse Declaration, we are persuaded at this stage that a hypothetical undergraduate physics degree holder would have adequate knowledge for one of ordinary skill in the art of the invention here. See Morse Decl. ¶ 31. As to the requisite years of experience proposed in the definitions— three for Petitioner versus “at least one” for Patent Owner—we note that Patent Owner’s definition is broader than, but includes, Petitioner’s definition. Moreover, for both the inclusion of physics and the years of experience issues, Patent Owner acknowledges that the arguments in the Preliminary Response “are not impacted based on which definition is applied.” Prelim.

“B. Claim Construction In inter partes reviews, the Board interprets claim language using the same claim construction standard that would be used in a civil action under 35 U.S.C. § 282(b), as described in Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc). See 37 C.F.R. § 42.100(b). Under that standard, we generally give claim terms their ordinary and customary meaning, as would be understood by a person of ordinary skill in the art at the time of the invention, in light of the language of the claims, the specification, and the prosecution history. See Phillips, 415 F.3d at 1313–14. Although extrinsic evidence, when available, may also be useful when construing claim terms under this standard, extrinsic evidence should be considered in the context of the intrinsic evidence. See id. at 1317–19. Petitioner does not propose express constructions for any claim terms. Pet. 12. Patent Owner also does not propose any express constructions. See Prelim. Resp. 12.

“On this record, it is not entirely clear that comparing a BSS color value to determine if a receiving station is in that BSS is prohibited by the claim’s recitation “not to use” a BSS color, as Patent Owner’s argument implies. Rather, claim 1’s recitation “not to use a Basic Service Set (BSS) color when signaling information indicates that an operation based on the BSS color is not allowed” appears directed to prohibiting a particular operation based on the BSS color, not necessarily disregarding the BSS color entirely. Further, comparing BSS values to determine BSS identity appears consistent with claim 1’s recitation that “the BSS color is an communication terminal recognizes that a BSS color collision has occurred.” On this record, it appears that BSS color would need to be identified to determine if a color collision occurs. See Prelim. Resp. 4 (“BSS color collisions occur when two or more BSSs operating on the same frequency channel (and overlapping in coverage area) use the same BSS color. See ’163 Patent at 2:46-59, 10:41-62. In other words, a wireless communication terminal receives a signal with the same BSS color that device understands applies to it, even though the signal is intended for another device in a different BSS (albeit using the same BSS color). When a color collision is detected, the wireless communication terminal reports to the base wireless communication terminal, which will indicate that a color collision has occurred. ’163 Patent at 3:16-20.”). In that light, we see some merit in Petitioner’s position that an “operation based on BSS COLOR (e.g., allowing access and re-using the channel) is not allowed” based on the Low Power/High Interference Indicator, even if some reference is made to the BSS color to resolve a condition precedent to that determination, namely whether the data are from a different BSS. See Pet. 53–54 (citing Ex. 1009 ¶ 26; Ex. 1003 ¶ 170). Petitioner’s second theory is based on setting the color field to a reserved value of “0000,” which Petitioner argues “indicates that operations based on BSS COLOR are not allowed and the receiving STA does not use BSS COLOR.” Pet. 54–55 (citing Ex. 1009 ¶¶ 25, 29; Ex. 1003 ¶ 172). On this record, we question how setting a color value to 0000 can teach the subject matter of claim 1, which also requires that “the BSS color is an identifier of a BSS.” Petitioner acknowledges that a reserved value of 0000 in the color field does not identify a BSS. See Pet. 54–55 (asserting that a that a COLOR field value of ‘0000’ does not represent a valid BSS identifier”). We also recognize, however, that claim 7, depending from claim 1, recites “the BSS color indicated by the signaling field of the PPDU is a predetermined value” and that claim 8, depending from claim 7, recites that the predetermined value is 0. Thus, Choudhury’s reserved value disclosures appear to teach this subject matter of claims 7 and 8, even if claims 7 and 8 are inconsistent with claim 1’s requirement that “the BSS color is an identifier of a BSS.” See Ex. 1001, 21:23–30 (disclosing that the BSS color value may be set to a predetermined value such as zero).” slip op. at 12

“In evaluating arguments under § 325(d), we use a two-part framework to assess: (1) whether the same or substantially the same art previously was presented to the Office or whether the same or substantially the same arguments previously were presented to the Office; and (2) if either condition of first part of the framework is satisfied, whether the petitioner has demonstrated that the Office erred in a manner material to the patentability of challenged claims. Advanced Bionics, Paper 6 at 8. In applying the two-part framework, we consider the non-exclusive factors set forth in Becton, Dickinson and Co. v. B. Braun Melsungen AG, IPR2017-01586, Paper 8 (PTAB Dec. 15, 2017) (precedential in relevant part) (“Becton, Dickinson”), which “provide useful insight into how to apply the framework” under § 325(d). Advanced Bionics, Paper 6 at 9. Those non-exclusive factors include: (a) the similarities and material differences between the asserted art and the prior art involved during examination; (b) the cumulative nature of the asserted art and the prior art evaluated during examination; (c) the extent to which the asserted art was evaluated during examination, including whether the prior art was the basis for rejection; (d) the extent of the overlap between the arguments made during examination and the manner in which Petitioner relies on the prior art or Patent Owner distinguishes the prior art; (e) whether Petitioner has pointed out sufficiently how the Examiner erred in its evaluation of the asserted prior art; and (f) the extent to which additional evidence and facts presented in the Petition warrant reconsideration of the prior art or arguments. Becton, Dickinson, Paper 8 at 17–18. “If, after review of factors (a), (b), and (d), it is determined that the same or substantially the same art or arguments previously were presented to the Office, then factors (c), (e), and (f) relate to whether the petitioner has demonstrated a material error by the Office.” Advanced Bionics, IPR2019-01469, Paper 6 at 10.4” slip op. at 10

“(xiii) Conclusion for Claim 1 Based on the evidence and arguments of record at this stage of the proceeding, we determine that Petitioner has shown that each element of claim 1 of the ’550 patent is disclosed by the combination of Barg and Pintor. Since Petitioner did not assert that Pintor discloses any limitation of claim 1, we determined that Petitioner did not need to establish a motivation to combine Pintor or reasonable expectation of success in doing so for claim 1. Lastly, Patent Owner’s objective indicia did not relate to claim 1. Accordingly, Petitioner has shown a reasonable likelihood that claim 1 would have been obvious over the combination of Barg and Pintor.” slip op. at 41

During prosecution of the ’878 patent (which is a parent of the ’551 patent at issue in this proceeding), Boatright was distinguished because it did not have an upper edge of the cup that lies “along a same edge line as at least a portion of a top edge of the chest strap,” as required by claim 1. Prelim. Resp. 15 (citing Ex. 2066, 105). Vidal shows “an upper edge of the side patch lying along a same edge line as at least portion of the top edge of the chest strap” (as required by claim 1) in that Vidal’s Figure shows such alignment. Moreover, Vidal states that the shape of its pocket (i.e. side patch) “can be adapted to the shape of the side strap.” Ex. 1027, 3:19–20. Given these disclosures, Vidal is not cumulative of Boatright. As to Sherwood and Gentry, Patent Owner’s arguments that these references relate to bras with pockets such that Vidal is cumulative to them are unconvincing as Vidal is relied upon to teach more than a bra with pockets. For these reasons, part one of the Advance Bionics framework is not satisfied for Vidal. Both parties agree that Handras was presented to the Office in an Information Disclosure Statement. Pet.

“substantially the same as Pintor, for purposes of this Decision, we need not address this issue.10 As discussed below, even if the asserted references are substantially the same, we are persuaded that Petitioner has demonstrated, under the second prong of the Advanced Bionics framework, that the Office erred in a manner material to the patentability. To determine whether Petitioner has sufficiently shown material error, we look at, for example, “the extent to which the asserted art was evaluated during examination, including whether the prior art was the basis for rejection.” Advanced Bionics, 9. As explained above, during prosecution of the ’288 patent, the examiner rejected the then-pending claims over Newman in view of Pintor. Ex. 1004, 151–52. Petitioner argues, however, that the examiner considered Pintor “only as a secondary reference to Newman.” Pet. 96. According to Petitioner, the examiner “overlooked how a POSA would have understood Pintor’s disclosures and what a POSA would have been motivated to do with them, especially in light of references like Barg, York, and Handras.” Id. at 10. On this record, we find Petitioner’s argument persuasive. Patent Owner does not dispute that Pintor discloses “a bra with left and right cups, shoulder straps, and a chest strap,” and “additionally discloses the bra cups 10 Patent Owner further asserts that the examiner “considered several other patents and patent applications relating generally to bras with pockets, both as provided in an IDS and as a result of the Examiner’s own searching, including U.S. 7,585,200 to McLaren, and U.S. 5,496,205 to Lee.” Prelim.

Such a bare bone assertion is insufficient to show those other patents and patent applications are cumulative to the prior art asserted in the Petition. comprised of polyurethane and the pockets made of elastic material.” Prelim. Resp. 18. The examiner, however, relied on Pintor for teaching a single limitation, that is, Pintor’s pocket “holds the claimed items therein.” Ex. 1004, 152. Patent Owner is correct that, when rejecting the pending claims over Sherwood, the examiner did not have to repeat Pintor’s teachings of the limitations taught in Sherwood. The examiner, however, failed to consider Pintor’s teaching in its entirety after the applicant distinguished the pending claim over Sherwood. Ex. 1006, 92 (the applicant arguing “Sherwood teaches a front padding that is stitched in place” in contrast to the pending claims’ requirement that “the opening is capable of repeated receiving and removal of items when the bra is being worn by the user”).

“b. Evidence Related to Nike Products Patent Owner argues that there is “a high degree of correspondence between features of [Nike’s] Swoosh on the Run and the claims of the ‘036 patent.” Prelim. Resp. 29 (citing Ex. 2053). The evidence, however, do not support a conclusion that Nike’s Swoosh on the Run is coextensive with the ’036 patent’s claimed invention. Indeed, Patent Owner submits claim charts allegedly showing that Nike’s Swoosh on the Run infringes not only the ’036 patent (Ex. 2053), but also four other patents in the family (Exs. 2054–2057). Those other claim charts demonstrate that Swoosh on the Run includes many features not claimed in the ’036 patent. See e.g., Ex. 2055 (showing Swoosh on the Run has a back pocket). Thus, on this record, Patent Owner has not persuasively shown a rebuttable presumption of nexus between Nike’s Swoosh on the Run and the challenged claims. Patent Owner asserts that “there is significant evidence that NIKE copied the patented application in the ‘036 patent.” Prelim. Resp. 28–29. According to Patent Owner, “NIKE received copies of patents and sample products from [the named inventor of the ’036 patent] Ms. Goff prior to filing its patents or marketing any of the allegedly infringing products.” Id. at 29. Patent Owner alleges that “each of the Swoosh Pocket Bra, the Swoosh Bra, and the Swoosh on the Run has several points of similarity both to the product depicted and described in Ms. Goff’s patents as supplied to NIKE and to the product samples Ms. Goff sent to NIKE.” Id. Ms. Goff testifies that she corresponded with Nike about her Pocket Bar and submitted examples of her products. See Exs. 2001, 2035. Patent Owner’s evidence, however, does not sufficiently demonstrate that a specific product was replicated. See Iron Grip Barbell Co. v. USA Sports, Inc., 392 F.3d 1317, 1325 (Fed. Cir. 2004) (“[C]opying requires the replication of a specific product.”). In addition, neither Ms. Goff’s testimony nor the Nike Idea Submission is specific to the ’036 patent’s claimed invention. See generally Exs. 2001, 2035. For example, none of the pictures in the Nike Idea Submission sufficiently shows certain feature of the ’036 patent’s claimed invention, which includes “the upper edge of the patch being offset from an upper edge of the cup.” See, e.g., Ex. 2035, 2–4.
