Eric Buresh

I'll research Eric Buresh's professional background before drafting.

Let me look into the specific tracked matters and verify outcomes.

Eric A. Buresh — Erise IP, P.A. (Overland Park, KS)

Specialty / focus. Buresh is a first-chair patent trial lawyer and founding member of Erise IP, with an engineering background (B.S., mechanical engineering) and a practice concentrated in electronics and software rather than pharma or life sciences. Firm and third-party profiles describe recurring work in video game technology and consoles, networking equipment and network security, deep packet inspection, digital rights management, GPS, e-commerce and consumer electronics. The tracked matters add transaction processing/payment systems (AuthWallet) and web video/interactive media (RazDog), consistent with that electronics-and-software focus. He also does PTAB work across a wide range of technologies, including consumer products and medical devices in prosecution-adjacent matters.

Side preference. The tracked case list shows four petitioner/plaintiff-side appearances and zero defendant-side appearances, but that sample is dominated by PTAB proceedings and Unified Patents matters and should not be read as a defense-averse practice. In IPR/PGR work he regularly appears as petitioner counsel for Unified Patents, the defensive aggregator that challenges NPE-owned patents (the tracker's "plaintiff" label reflects petitioner status in those proceedings, not district court alignment). At the same time, his publicly reported district court record is overwhelmingly defense-side for operating companies, and he has also appeared as plaintiff's counsel for Stingray IP Solutions, a patent-assertion entity. The accurate characterization is a mixed-side practice: petitioner/defense work for technology companies and Unified Patents, with occasional patent-owner representation.

Firm context. Buresh is a founding member of Erise IP, an IP litigation boutique headquartered in Overland Park, Kansas, with additional offices including Denver. Public sources do not clearly document his practice before Erise's founding; his pre-firm history is not well sourced beyond a post-J.D. clerkship focused on patent matters.

Notable matters and outcomes (verified).

• Unified Patents, LLC v. AuthWallet, LLC (IPR2021-01260): Erise represented petitioner Unified Patents; the PTAB issued a final written decision on Jan. 31, 2023 holding all challenged claims of U.S. Patent 9,292,852 unpatentable. The patent had been asserted against Citigroup, Square, American Express, Starbucks and Nordstrom.
• Infernal Technology LLC and Terminal Reality Inc. v. Sony Interactive Entertainment: Buresh was part of the team that won a complete defense verdict in the Eastern District of Texas that PlayStation consoles and games did not infringe light-rendering patents; the verdict was affirmed by the Federal Circuit, and the district court denied a new-trial motion. The same dispute was later ended via IPR, with the PTAB invalidating three patents and 21 claims. This work contributed to his Law360 2022 IP MVP recognition.
• Longhorn HD LLC v. NetScout Systems: defense verdict of non-infringement in the Eastern District of Texas; the jury reportedly deliberated less than an hour and rejected the NPE's patent claim.
• Firm bios credit him with four consecutive Eastern District of Texas defense verdicts and more than 30 Federal Circuit appeals as lead counsel.
• Unified Patents, LLC v. RazDog Holdings LLC / Twitch Interactive v. RazDog: the Erise team (Buresh, Nick Apel, Caroline McCord) represents Unified in an ex parte reexamination of U.S. Patent 10,334,068, instituted by the Central Reexamination Unit in May 2025; the parallel RazDog IPRs were filed by Twitch Interactive through separate counsel, and Acting Director Coke Morgan Stewart declined to discretionarily deny institution in May 2025.

PTAB / IPR experience. Extensive. Firm bios state he has filed more than 115 inter partes review proceedings at the PTAB and that he was named to Patexia's "Top 100 Most Active IPR Attorneys for Petitioners." His tracked PTAB work for Unified Patents fits a broader practice of using post-grant proceedings to resolve or terminate parallel district court litigation.

Bar / education. J.D., summa cum laude, Washburn University School of Law (2000); B.S., mechanical engineering, Cedarville University (1997). Admitted in Kansas and Missouri, before the U.S. Court of Appeals for the Federal Circuit (and other federal courts), and registered to practice before the U.S. Patent and Trademark Office (Reg. No. 50,394). Registration number and most admission dates are sourced from Martindale, Best Lawyers and USPTO filings.

Note on sourcing: the four tracked appearances come from the structured list provided, which reflects a narrow slice of a much larger docket (his bios reference 200+ patent matters). The Stingray IP Solutions matter could not be independently verified in available sources and is reported here only as tracked.
