I'll research this attorney before drafting.

Kirill Y. Abramov — Patent Litigation Practice Summary

Focus areas. Abramov is an in-house intellectual property litigation executive rather than a firm-side patent litigator. Public filings identify him as Group Vice President and Associate General Counsel, Intellectual Property Law at Charter Communications, Inc., where he manages Charter's patent and IP litigation docket. The technology profile of the matters in which he appears tracks Charter's business: cable/broadband networking and customer-premises equipment, data-over-cable (DOCSIS) and video delivery systems, set-top/CPE and wireless access technologies. The one case in the tracked dataset is Headwater Research LLC v. Charter Communications, Inc., with Abramov appearing on the defendant side in an in-house role. Consistent with a broad IP portfolio remit, his name also appears in the record of copyright litigation (Warner Records Inc. v. Charter Communications, Inc., D. Colo.) as the in-house counsel managing the matter.

Side preference. Exclusively defense-side on the structured data: 0 plaintiff appearances, 1 defendant appearance, role recorded as in-house. This is consistent with an operating-company practice — Charter is sued by NPEs/PAEs and by operating competitors, and Abramov's function is to direct the defense (and the accompanying IPR strategy) rather than to assert patents offensively. Any plaintiff-side licensing activity is not documented in the tracked data.

Firm context. In-house at Charter Communications. Court filings give his Charter address in Stamford, Connecticut, and professional directory listings also associate him with Charter's St. Louis, Missouri office. I found no reliably sourced record of prior law-firm affiliations, so none is stated here.

Notable matters and PTAB activity. Beyond the tracked Headwater Research case, he is identified in court filings as Charter's in-house counsel in Entropic Communications LLC v. Charter Communications (E.D. Tex.), where the Entropic CEO's licensing demand letter was addressed to him, and in Sprint Communications Co. v. Charter Communications (D. Del.), where Judge Andrews' August 2020 discovery order discusses the treatment of Abramov's files and Charter's privilege assertions as to those documents. On the PTAB side, he signs as Charter's authorized signatory/officer on several IPR petitions — for example IPR2025-00473 (Iarnach Technologies, U.S. Pat. 9,674,035), IPR2024-01379 (Adaptive Spectrum and Signal Alignment, U.S. Pat. 7,809,996), and the 2019 Sprint-related petitions (IPR2019-01135, -01136, -01137, -01138, -01140) — indicating regular oversight of, though not necessarily appearance as lead counsel in, Charter's IPR practice. No verdicts, Federal Circuit outcomes, or settlement terms attributable to him personally were verifiable from public sources; treat any such claim as unsupported.

Bar / education. Not reliably sourced. The only professional-profile listing found uses a Missouri address and describes him as an intellectual property lawyer, but I could not verify a bar admission or law school from a citable source, so both are omitted. Note also that the name is shared — an unrelated New York attorney (Kirill Nikonov) and unrelated patent prior-art references to an "Abramov" appear in search results and should not be conflated with this attorney.
