Ronald R. Wielkopolski — patent litigation summary

Focus areas. Wielkopolski is a Washington, D.C.–based trial lawyer whose practice centers on patent litigation and related IP disputes, with additional work in trade secret, false advertising, and antitrust claims arising out of the same technology fights. The tracked matters and firm biography point to a network- and software-heavy docket: Internet proxy/data-communication technology (Bright Data/Luminati), wireless routers and networking equipment (Ruckus Wireless, and a defendant-side router manufacturer), and mechanical/consumer products (air mattresses for Team Worldwide). He also handles trade secret and unfair competition claims alongside patent counts in the same actions, and his firm bio lists PTAB and ITC Section 337 work as core practice areas. He is a registered patent attorney (USPTO Reg. No. 69,359), which the bio's science background (Berkeley B.A., molecular & cell biology) suggests informs his claim-construction and invalidity work.

Side preference. His tracked appearances skew heavily plaintiff-side — four plaintiff matters against one defendant-side matter — and in practice that has meant representing patent owners and technology companies asserting claims, including proxy/Internet infrastructure companies and smaller patent-holding entities such as IOT Innovations LLC in its action against Fortinet. He is not exclusively a plaintiff's lawyer, however: his bio describes defending wireless router manufacturers in the Central District of California and in multi-district litigation in Delaware that settled after a favorable claim construction ruling, and he has appeared as petitioner-side counsel for Ruckus Wireless in PTAB proceedings. The overall pattern is closer to a plaintiff/patent-owner practice with a secondary defensive and IPR-petition practice.

Firm context. He is a partner in the Washington, D.C. office of Cherian LLP, the firm formerly known as RuyakCherian LLP (a related entity appears in the docket as Cherian Harkins Dunham / CHD Law). His tracked cases span each of those name iterations, consistent with the firm's rebranding rather than lateral moves. Before joining the firm he was an associate at Urrabazo Law PC, where he worked on the VimetX litigation against Cisco, Apple, and Microsoft on behalf of co-plaintiff Science Applications International Corporation. No in-house affiliation appears in the record.

Notable cases and outcomes. The most prominent tracked matter is Bright Data, Ltd. (f/k/a Luminati Networks) v. Teso LT, UAB et al. (E.D. Tex. No. 2:19-cv-00395), where the November 5, 2021 jury verdict found infringement, willful infringement, no invalidity on the asserted claims, and awarded $7,474,876 in lost profits. The outcome was mixed on appeal: the parallel IPRs invalidated the asserted patent family, and the Federal Circuit affirmed the Board's obviousness and claim-construction rulings on August 1, 2025 in Bright Data, Ltd. v. Code200, UAB, Nos. 23-2144 et al. — two of the docket numbers tracked here (23-2145 and 23-2443) are part of that consolidated appeal. He also represented patent owner Team Worldwide Corporation in Team Worldwide v. Walmart (E.D. Tex.) and the related IPRs on the '394 patent, which produced a pre-trial settlement against a large retailer. A July 2025 Cherian firm announcement naming him among the team that prevailed for client "OIT" is publicly reported but the underlying case and result are not described in the sources reviewed, so treat that item as unverified.

PTAB / IPR experience. Yes — this is a regular part of his practice. He has served as counsel of record for patent owners in the Team Worldwide IPR series (IPR2018-00859 through -00875) and for Bright Data in the IPR2021-01492/01493 proceedings, and as counsel for petitioner Ruckus Wireless in an IPR on U.S. Patent No. 5,915,210. The tracked IPR2021-01492 entry reflects that work.

Bar and education. Admitted in the District of Columbia and Maryland, admitted before the Federal Circuit and the Eastern District of Texas, and registered with the USPTO; J.D., George Washington University Law School; B.A., UC Berkeley; M.A. in History, Georgetown. Member, American Intellectual Property Law Association.
