Michaela P. Sewall

I'll research this attorney's background and verify the tracked cases.

Michaela P. Sewall — patent litigation practice (research summary)

Focus areas. Sewall's practice is intellectual property litigation, with WilmerHale's own profile describing patent disputes spanning microprocessors, smartphones, medical devices, pharmaceuticals and automotive technology. Her tracked matters are consistent with a standards-and-electronics emphasis: the two named cases involve Wi-Fi 6/6E (IEEE 802.11ax) wireless chipsets, adapters and access points, MAC-layer/medium-access protocols, secure-proximity and TPM functionality, and VoIP/communications networking patents from the former Avaya portfolio.

Side of the "v." She is defense-side only in the tracked data — 0 plaintiff appearances, 3 defendant-side appearances. Both named cases fit that pattern: defending Intel in Proxense, LLC v. Intel Corp. (W.D. Tex.) against an NPE asserting Wi-Fi and passwordless-authentication patents, and defending Comcast in Arlington Technologies, LLC v. Comcast Cable Communications, LLC (E.D. Tex.), a Dominion Harbor entity campaign over former Avaya patents. Her PTAB work is more mixed: she was admitted pro hac vice as back-up counsel for the petitioner (Precision Planting) in a consolidated set of Deere IPRs, and appears more recently on the patent-owner side in a 2025 IPR.

Firm context. She is based in Boston and is currently listed on WilmerHale's site as Special Counsel; the tracked data lists her as Counsel and as lead counsel on WilmerHale matters. The same tracked data records an appearance in the Arlington/Comcast matter under Davis Polk & Wardwell as Of Counsel. I could not independently verify that Davis Polk appearance — the public E.D. Tex. docket entries I located list Comcast's counsel of record as Duane Morris and The Dacus Firm, and searches for a "Michaela Sewall / Davis Polk" connection returned nothing. That entry should be treated as unconfirmed. Before private practice she clerked for Judge Nathaniel M. Gorton (D. Mass., 2011–2012).

Notable matters. Proxense v. Intel (6:24-cv-00283) is the most prominent: it targets Intel's Wi-Fi 6-and-later processors and adapters, and Intel's parallel IPRs (IPR2025-00327/-00328/-00329) were discretionally denied in June 2025 by Acting Director Stewart on "settled expectations" grounds — a denial that has been widely cited. I cannot confirm from available sources whether Sewall personally staffed those Intel IPRs. In Arlington v. Comcast (2:24-cv-00768 and -00769), the cases were stayed for settlement in January 2025 and dismissed with prejudice in March 2025; separately, Unified Patents' ex parte reexamination of asserted U.S. Patent 7,193,986 resulted in a 2026 notice of intent to cancel claims 1–3, 5–6 and 8–9.

PTAB / IPR. She has meaningful PTAB exposure. She was granted pro hac vice admission as back-up counsel in IPR2019-01048, -01050, -01052 and -01054 (Precision Planting LLC v. Deere & Company) in June 2020 — the orders note that a registered practitioner had to remain lead counsel, which suggests she may not be USPTO-registered herself; that inference is not confirmed. She also appears on a late-2025 patent-owner-side filing in IPR2025-01326.
