Marvin E. Key

I'll research this attorney before drafting the summary.

Interesting — I'm seeing a possible name collision. Let me dig further.

Summary: Marvin E. Key

Scope of the record. Mr. Key has a single tracked patent-litigation appearance, on the defendant side and in an in-house capacity, in LG Display Co., Ltd. et al. v. Innovative Display Technologies LLC. No plaintiff-side appearances are recorded. That dispute centered on display-optics patents — light-emitting panel assemblies, backlight units, and light-extraction "deformity" structures used in LCD backlights (e.g., U.S. Patents 6,755,547; 7,384,177; 7,404,660) — asserted by Innovative Display Technologies LLC ("IDT"), a patent-licensing entity then affiliated with Acacia Research Corporation. The technology focus in the record is therefore display/optics hardware, not pharma, software, or wireless standards.

Side preference. The tracked counts (0 plaintiff / 1 defendant) are thin and should be read with a caveat. Public records identify a "Marvin Key" as an executive of Acacia Research's patent licensing and enforcement business — Senior Vice President from 2005, CEO of Acacia Research Group LLC from January 2013, and Interim CEO of Acacia Research Corporation from December 2015 — and as the CEO who signed a patent-owner power of attorney on behalf of Acacia subsidiary Cellular Communications Equipment LLC in IPR2014-01131. If that is the same individual, his vantage point is the patent-owner/assertion (NPE) side as a licensing executive rather than a defense-side advocate, even though the tracked docket carries him as a defendant. I could not confirm the identity match or locate a bar-admitted litigation profile, so this should be verified before being relied on.

Firm context. No law-firm affiliation appears in public sources; the record and available documents place him in-house. On the Acacia-identity theory, the relevant corporate context is Acacia Research (later renamed) and its assertion subsidiaries, including IDT and Cellular Communications Equipment LLC — not a law firm platform.

Notable matters and PTAB activity. The LG Display side of the IDT dispute was litigated by outside counsel (Mayer Brown) through a series of inter partes reviews against IDT's backlight patents, including IPR2014-01357, IPR2014-01362, and IPR2015-00487; the Board instituted on the '177 patent in a March 2, 2015 decision, and parallel district court litigation proceeded in Delaware (Delaware Display Group LLC and IDT v. LG Electronics, Inc., LG Display Co., Ltd., et al., No. 1:13-cv-02109). No verdict, settlement, or Federal Circuit outcome attributable to Mr. Key personally is verifiable from the sources reviewed, and no IPR/PGR filings naming him as counsel were found — his only located PTAB signature was a corporate-capacity power of attorney, which does not evidence registered-practitioner status.

Bar / education. Not reliably sourced; omitted.
