“Paper 34. Birchtech Corp. (“Patent Owner”) filed a Request for Director Review in each case. See Paper 40; IPR2025-00422, Paper 39. The Director denied the request without prejudice in each case and remanded the cases to the Board to “allow discovery, narrowly tailored to resolve the RPI and privity issues.” Paper 49, 4. The Director later issued an Order Supplementing Director Review Decision in each case, instructing that “if the Board determines that Petitioners met their burden to identify all RPIs in the Petitions, then the Board should maintain at most one IPR challenging” the ’430 patent.

“Petitioner’s arguments are not persuasive. Petitioner was aware of the challenged patent no later than February 2012, and Patent Owner specifically identified the patent as being of interest to mobile commerce providers. See Ex. 2004. Petitioner cited the challenged patent to the Office during prosecution of Petitioner’s own Application No. 13/716,675 in December 2012. See Ex. 2007. Application No. 13/716,675 is titled “Methods and Systems for Efficient Discovery of Devices in a Peer-to-Peer Network.” See Ex. 2006. Efficient discovery of devices in a peer-to-peer network appears to be relevant to both retail operations and the finding and tracking of personal electronic devices. Accordingly, Petitioner’s own actions indicate it was aware that the challenged patent was relevant to its technology space.” slip op. at 3

“Finally, I do not agree with Petitioner’s assertion that the Office committed a material error during prosecution. While demonstrating error is usually one of the strongest considerations weighing against discretionary denial, here Petitioner’s material error argument is weak. Petitioner points to the notice of allowance, and focuses on a single phrase that appears in a rather long listing of limitations the examiner indicated were missing from the prior art. DD Opp. 2–3. According to Petitioner, the phrase “first, direct, short range separate local wireless link” never existed in the claims. Id. at 4. However, Petitioner acknowledges that the phrase “via a separate local wireless link” was part of the claims, as was the phrase “first, direct, short range” local wireless link. Id. Although the ultimate listing in the notice of allowance may constitute a clerical error, Petitioner has not demonstrated sufficiently that this error was material to the patentability of the challenged claims, especially considering the number of other limitations listed in the notice of allowance that the examiner determined to be missing from the reviewed prior art. Petitioner does not address those limitations in its error arguments. Id. at 3–6.” slip op. at 3

“If reasonable minds can disagree regarding the purported treatment of the art or arguments, it cannot be said that the Office erred in a manner material to patentability.” Advanced Bionics, Paper 6 at 9; see Ecto World, LLC v. RAI Strategic Holdings, Inc., IPR2024-01280, Paper 13 at 6 (Director May 19, 2025) (precedential) (“Ecto World”).

“As I have indicated previously, a petitioner should present a single construction and apply that construction consistently. See Infineon Techs. 1 Citations are to papers in IPR2026-00133. The parties filed similar papers in IPR2026-00134 and IPR2026-00135. Americas Corp. v. Mosaid Techs. Corp., IPR2025-01456, Paper 27 at 3–4 (Director Mar. 17, 2026). Failure to do so, without adequate explanation, is problematic. Id.; Revvo, Paper 20 at 3–4. A petitioner may not avoid presenting its own claim construction position in a proceeding before the Office by presenting an analysis based on claim construction positions taken by other parties in a different proceeding. See 37 C.F.R. § 42.104(b)(3) (requiring that the petition must “set forth . . . [h]ow the challenged claim is to be construed”); Trial Practice Guide2 §§ II.B.(3) and (6). Permitting such conduct would allow a petitioner to avoid taking a consistent claim construction position. Such conduct would undermine the purpose of inter partes review proceedings and detract from the Office’s goal of “providing greater predictability and certainty in the patent system.” Revvo, Paper 20 at 4–5. While certain arguments are highlighted above, the determination to exercise discretion to deny institution is based on the complete record and a holistic assessment of all of the evidence in light of the arguments presented.” slip op. at 2
