P.J. Cherian

I'll research this attorney's background before drafting.

Let me dig specifically for this individual.

Let me try a few more targeted searches to confirm whether this attorney exists in the IP bar.

Verification caveat up front: I could not verify a patent litigator named "P.J. Cherian." The authoritative case list contains a single tracked appearance — one defendant-side matter, counsel role, at Cherian Harkins Dunham — and the case itself is recorded as untitled, with no court, docket number, technology area, or outcome. Independent searching for this name in the IP bar returns only a Kerala-based archaeologist (Prof. P.J. Cherian, PAMA Institute), unrelated individuals, and a different attorney nicknamed "PJ" practicing military law in Virginia. There is also a "Cherian" who appears as an inventor/prior-art reference in Wi-Fi 802.11 EDCA patents (e.g., Samsung's IPR of U.S. Pat. No. 11,116,035) — that is a technologist, not an attorney. Nothing in the record supports attributing a patent litigation practice to this name, so the summary below describes only what is verifiable and should be treated as provisional.

Firm context (verifiable). Cherian Harkins Dunham LLP is a trial-focused IP litigation boutique founded in 2015 as Cherian LLP by Korula "Sunny" Cherian; effective January 1, 2026 it was renamed Cherian Harkins Dunham LLP, with Robert M. Harkins, Jr. and Thomas M. Dunham as named partners (Harkins serves as managing partner). Offices are in Oakland, California (relocated from Berkeley), Washington, D.C., and Houston/Dallas, Texas. The firm's practice spans patent litigation in EDTX/WDTX, the California districts, Delaware, EDVA and the Federal Circuit; ITC Section 337; PTAB post-grant work; and copyright, trademark, and trade secret matters. Technology coverage is broad — electrical and mechanical engineering, semiconductors, networking and telecommunications, computer hardware/software, internet technologies, industrial equipment, medical devices, and life sciences. If P.J. Cherian is in fact at this firm, that is the practice context a defense-side patent role would sit within.

Side preference. The data shows 0 plaintiff-side and 1 defendant-side appearance, as counsel. A single appearance cannot establish a practice pattern, and I found no public filings, verdicts, or firm biographies corroborating a plaintiff or defendant lean for this name.

PTAB / IPR and bar/education. No IPR, PGR, or other PTAB appearances are attributable to this individual in the sources reviewed, though the firm itself advertises regular IPR/PGR/EPR and reissue practice and deliberately staffs the same team across district court, PTAB, and appeals. No bar admission, law school, or technical degree could be reliably sourced for P.J. Cherian specifically, so I have omitted them.

Disambiguation note: If the intended subject is the firm's identifiable IP litigation partner, that person is Korula T. "Sunny" Cherian (California bar, 1988; UC Davis J.D. 1987; MSEE George Washington University; BSEE University of Mysore) — a different individual from the name given, and one whose credentials should not be merged into this profile without confirmation.
