Specialty & background

Summary — Kristen Schunter (Kristen Leigh Schunter)

Specialty / focus. Kristen Schunter is a California intellectual-property attorney whose tracked docket is concentrated in patent validity challenges before the PTAB, with her Perkins Coie work involving Flexiworld Technologies' wireless/software-content-distribution patents and Roku's streaming-media technology. Her USPTO registration (Reg. No. 76,519) reflects substantial patent-prosecution work; public USPTO applicant data ties her to filings for Advanced Micro Devices, Xilinx, ATI Technologies, and Pensando Systems, indicating a semiconductor/computing-hardware prosecution background alongside her PTAB litigation practice.

Side preference. Her four tracked appearances are evenly split (2 plaintiff-side, 2 defendant-side), and the mix is telling: she has appeared both for Roku as IPR petitioner (counsel of record and back-up counsel) and for Flexiworld as IPR patent owner/defendant (including against Unified Patents). She therefore works both sides of the same dispute ecosystem — representing operating companies in validity challenges and defending patent owners against those challenges — rather than maintaining a strict plaintiff or defendant orientation.

Firm context and PTAB/IPR experience. She has practiced at Perkins Coie LLP (Palo Alto office per firm/bar listings), where PTAB filings identify her via a schunter-ptab@perkinscoie.com address alongside colleagues Patrick McKeever, Miguel Bombach, and Evan Day — strong evidence of a regular IPR/PGR practice group role. The tracked matters (e.g., Unified Patents, LLC v. Flexiworld Technologies, Inc. and multiple Roku, Inc. v. Flexiworld Technologies, Inc. proceedings, including IPR2022-01267) are all PTAB cases. Note a possible recent move: the California State Bar's current address listing places her at Advanced Micro Devices, Inc. in San Jose, which may indicate a transition in-house; web-sourced firm directories still list her at Perkins Coie as of 2026, so I could not fully verify her current employer.

Bar / education. She was admitted to the California State Bar in December 2019 and holds a law degree from Santa Clara University School of Law. No notable verdicts, Federal Circuit decisions, or settlements beyond the PTAB docket surfaced in this search, and I found no reliable confirmation of prior firms.
