Klemchuk

Klemchuk PLLC is an intellectual property boutique law firm headquartered in Dallas, Texas, focusing on litigation, intellectual property, transactional, and international business law. The firm primarily serves mid-market companies. Klemchuk has been regionally recognized, appearing in the 2024 U.S. News & World Report and Best Lawyers® "Best Law Firms" list for Intellectual Property Litigation and Patent Litigation in the Dallas/Fort Worth metropolitan area (Tier 2). Chambers and Partners also lists Klemchuk in its USA: Spotlight rankings for Intellectual Property in Dallas.

The firm's IP litigation practice spans a broad range of technology areas, including software, technology, e-commerce, telecommunications, and health technology, among others. Specific experience for lead attorneys extends to semiconductors, the Internet, ink technology, water pumping systems, and roofing systems. They handle various intellectual property disputes, including patent, copyright, trademark, and trade secret litigation.

Klemchuk represents both plaintiffs and defendants in intellectual property litigation in federal and state courts. The firm's founder, Darin M. Klemchuk, notes that his litigation practice has been "evenly balanced between IP enforcement and defense work," reflecting this dual-side representation. This is consistent with the firm's tracked case appearances, which include one plaintiff-side matter (Solmetex, LLC v. Ascentcare Dental Products, Inc.) and two defendant-side engagements (Fleet Connect Solutions LLC v. Ford Motor Company and Athena Security, LLP v. Amazon.com, Inc. et al.). The firm also frequently serves as local counsel in Texas federal courts for out-of-state parties in IP and commercial litigation.

While the firm has handled numerous IP disputes, including over 40 patent infringement cases, specific high-profile verdicts or significant public outcomes for the aforementioned tracked cases (Solmetex, Fleet Connect Solutions, and Athena Security) were not broadly reported in the search results.

Klemchuk's practice also encompasses post-grant review proceedings before the Patent Trial and Appeal Board (PTAB). The firm actively integrates PTAB and Trademark Trial and Appeal Board (TTAB) tactics with district court litigation strategies and has experience with parallel proceedings. However, a public record of the firm's specific volume of IPR/PGR filings or defense actions was not found.

Key partners in the firm's intellectual property litigation practice include founder and CEO Darin M. Klemchuk, who has extensive experience in over 500 intellectual property disputes, and Mark A. Stachiw, who is also part of the IP litigation team.
