Hanna Glomska Cohen — Patent Litigation Practice Summary

Specialty / focus areas. Ms. Cohen's tracked practice is concentrated in electronics and networking patents, particularly Wi-Fi and broadband/network technologies. The bulk of her appearances are in the CommWorks Solutions campaign, which asserts patents covering Wi-Fi Protected Setup (WPS), Wi-Fi Multimedia/WMM and 802.11-2007+ QoS, network access provisioning, and contention-free traffic detection against router, gateway, and ISP products. Her docket also spans imaging (KT Imaging USA), navigation systems (Mel NavIP), memory (Complex Memory), semiconductor and USB-bridge technologies, and networking/application-delivery software (FireNet Technologies suits against Citrix and KEMP). The through-line is consumer/enterprise electronics and standards-based networking rather than pharma, life sciences, or mechanical arts.

Side preference. She is exclusively a plaintiff-side patent litigator. The authoritative tracking shows 12 plaintiff-side appearances and zero defendant-side, and web-verified dockets confirm she appears as counsel of record for patent-assertion plaintiffs such as CommWorks Solutions, FireNet Technologies, KT Imaging USA, Mel NavIP, and Computer Circuit Operations. Much of this work is on behalf of NPE/PAE-type clients (CommWorks is an affiliate of IPInvestments Group, asserting patents acquired from Intellectual Ventures), so she functions as enforcement/prosecution-side counsel for patent monetization entities rather than as a defense-side operating-company advocate.

Firm context. All 12 tracked appearances are at Kheyfits Belenky LLP, where she is listed with a New York address (previously 80 Broad Street; also 1140 Avenue of the Americas, 9th Floor, New York). The firm's patent practice is closely identified with the same plaintiff-side assertion campaigns (frequently alongside Dmitry Kheyfits and Andrey Belenky). A Martindale listing surfaced an Arnold & Porter Kaye Scholer reference under a similar name, but that record could not be confirmed as the same attorney and should be treated as unverified; no reliable prior-firm history was otherwise located.

Notable matters and PTAB experience. The most prominent tracked matters are the CommWorks Solutions suits — including actions against Technicolor, Mediacom Communications, RCN Telecom Services, and related defendants — which are Wi-Fi/network-provisioning cases that have been resolved by consent judgment and through discovery/subpoena fights (e.g., a third-party subpoena dispute involving MediaTek chip source code, transferred from W.D. Tex. to S.D.N.Y.). A Kheyfits Belenky filing in a USPTO PTAB petition (with Ms. Cohen admitted pro hac vice) indicates some IPR/PGR-side involvement, but the available public record is not sufficient to characterize her as a regular IPR practitioner; this should be confirmed against the PTAB docket before being relied on.

Bar / education. Bar admissions and law-school/education details were not reliably sourced in the materials reviewed and are therefore omitted. Her USPTO correspondence and court filings consistently list the firm email hgcohen@kblit.com.

Caveat: Findings are based on docket records, firm filings, and secondary litigation coverage; prior-firm history, bar admissions, and PTAB frequency could not be fully verified and are flagged above where unresolved.
