Winstead

Winstead PC is a prominent national law firm headquartered in Dallas, Texas, with a substantial presence across Texas, and additional offices in New York, North Carolina, and Tennessee. Ranked 137th by AmLaw 200 and 163rd in Law360's 400 list of top U.S. firms based on attorney headcount, Winstead is recognized as a large regional to national firm. As of 2025, the firm reported having 307 attorneys.

The firm's intellectual property litigation practice handles a diverse range of technology areas. Winstead's IP lawyers possess deep technical diversity, advising clients on patents related to digital technology, including computer chips and programming, as well as innovations in life sciences, biotechnology, healthcare, and nanotechnology. Attorneys within the practice have experience with various technologies such as pharmaceuticals, chemical processes, electrical and mechanical engineering, signal processing, software, medical training devices, computer architecture, machine learning, artificial intelligence, virtual reality, gaming, and mobile communications.

Based on tracked appearances, Winstead has represented clients exclusively on the plaintiff side in patent litigation, with three recorded plaintiff-side appearances and no defendant-side matters. While the firm's website states that its IP litigators represent both IP owners and defend companies accused of infringement, the available case data indicates a current emphasis on asserting intellectual property rights for owners.

Notable work includes the representation of Orthosie Systems, LLC as a plaintiff against Spireon, Inc. While specific outcomes for Orthosie Systems, LLC v. Spireon, Inc. are not publicly detailed, Winstead attorneys have been involved in other significant IP litigation. For instance, shareholder Michael D. Karson was part of a trial team that secured a substantial jury verdict in the Northern District of Texas in a case involving virtual reality technology and intellectual property.

Winstead also maintains an active practice before the Patent Trial and Appeal Board (PTAB). The firm's IP litigators are equipped to resolve complex issues in various forums, including the U.S. Patent and Trademark Office. Miranda Y. Jones, a key patent litigation shareholder, has significant experience in parallel inter partes review (IPR) proceedings before the Patent Office, notably obtaining denials of institution for patent owners in multiple IPR challenges.

Key partners in Winstead's intellectual property litigation practice include Phillip B. Philbin, who chairs the Business Litigation Practice Group, Michael D. Karson, Miranda Y. Jones, and Jamie H.
