“To the extent Patent Owner contends that a person of ordinary skill in the art need not be defined as of the critical date, we disagree. Under Section 103, we must determine “if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains” (emphasis added). “Obviousness is determined from the vantage point of a hypothetical person having ordinary skill in the art to which the patent pertains.” In re Rouffet, 149 F.3d 1350, 1357 (Fed. Cir. 1998). Thus, we define the hypothetical person of ordinary skill in the art as of a time before the effective filing date. To the extent Patent Owner’s argument is that, to testify from the perspective of a person of ordinary skill in the art, one need not have been a person of ordinary skill in the art as of the critical date, we agree. Although one must at least possess ordinary skill in the art to testify from the perspective of a person of ordinary skill, [a]n expert need not have acquired that skill level prior to the time of the invention to be able to testify from the vantage point of a person of ordinary skill in the art. Rather, an expert can acquire the necessary skill level later and develop an understanding of what a person of ordinary skill knew at the time of the invention. Osseo Imaging, LLC v.

“C. Claim Construction The parties agree that no claim terms require express construction. Pet. 10; Prelim. Resp. 2–4. Patent Owner, however, notes that, in related district court litigation, Petitioner has asserted that some claims terms are indefinite. Patent Owner argues that the Petition should be denied because Petitioner has taken inconsistent claim construction positions between the district court and the Board. Paper 14 at 1–3 (citing Tesla, Inc. v. Intellectual Ventures II LLC, IPR2025-00340, Paper 18 at 4 (PTAB Nov. 5, 2025) (informative); Revvo Techs., Inc. v. Cerebrum Sensor Techs., Inc., IPR2025-00632, Paper 20 at 4–5 (PTAB Nov. 3, 2025) (precedential)). Petitioner responds that, in the related district court litigation, the parties have narrowed the claim construction disputes and that Petitioner accords the plain and ordinary meaning to claim terms and no longer asserts that any claim term of the ’077 patent is indefinite. Paper 15 (citing, inter alia, Ex. 1126 (Defendants’ Responsive Claim Construction Brief)). The evidence supports Petitioner’s position because, in the related district court litigation, the defendants agree with the plaintiff (Patent Owner) that certain phrases in the ’077 patent claims should be given their “[p]lain and ordinary meaning” and are “not indefinite.” Ex. 1126, 6 (native page 1). Thus, the record does not show inconsistent claim construction positions that warrant denial under PTAB precedent. See Revvo, Paper 20 at 5 (addressing a situation in which a petitioner advances “different claim construction positions” in district court and at the PTAB). See Realtime Data, LLC v.

“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.

“Petitioner asserts that “Yarger and Love are analogous art because they are both related to aspects of securely communicating analyte measurements over wireless links in CGM systems.” Id. at 20–21 (citing Ex. 1005, code (57); Ex. 1006, code (57); Ex. 1003 ¶ 69; In re Bigio, 381 F.3d 1320, 1325–27 (Fed. Cir. 2004)). Patent Owner does not dispute Petitioner’s contentions that Yarger and Love are analogous, and that a POSITA would have been motivated to combine them with a reasonable expectation of success. See generally Prelim. Resp. We determine that Petitioner shows sufficiently that Yarger and Love are analogous and that a POSITA would have been motivated to combine them with a reasonable expectation of success. Specifically, Yarger and Love are directed to similar glucose monitoring systems and are thus in the same field of endeavor and address the same problems. See, e.g., Pet. 20– 21; Ex. 1005, codes (54, 57), ¶ 1; Ex. 1006, codes (54, 57), ¶ 2. Since Yarger already monitors and displays glucose levels, including clinically significant conditions such as hypoglycemia or hyperglycemia, adding Love’s teaching to generate alarms and notifications for such conditions would improve Yarger’s similar system in the same way as taught by Love. See, e.g., Pet. 19–21; Ex. 1005 ¶¶ 3, 17; Ex. 1006, codes (54, 57), ¶¶ 70, 78. Since this modification merely requires “routine programming” adding logic to compare glucose levels and generate an alarm when a clinically significant threshold is exceeded, a POSITA would have had a reasonable expectation of success in making the modification. See, e.g., Pet. 20; Ex. 1003 ¶ 73. “[I]f a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417.” slip op. at 18
