Devlin Law Firm

Devlin Law Firm LLC is an intellectual property boutique law firm headquartered in Wilmington, Delaware, a key venue for patent litigation. While not an AmLaw-ranked firm, it operates as a specialized patent shop with a team of more than 25 attorneys. The firm has been recognized as a “Powerhouse Delaware patent law firm” by Law360 and provides representation in major patent venues across the United States. The practice leaders, Timothy Devlin and James M. Lennon, bring prior experience from larger firms, positioning the firm as a provider of "big firm expertise" with the flexibility of a smaller, entrepreneurial structure.

The firm's litigation practice covers a broad range of technical areas, including computer technology, software, networking, biological sciences, and chemical and mechanical engineering. The provided case list reflects this technology focus, with matters such as Umbra Technologies Ltd. v. Zscaler, Inc., involving network virtualization and security patents, and Twitch Interactive, Inc. et al. v. NL Giken Inc., which pertains to interactive media. The firm markets its ability to handle patent disputes across any technology sector, leveraging the diverse technical backgrounds of its legal team.

Devlin Law Firm represents clients on both sides of patent disputes, a fact supported by the authoritative case list showing an even split between plaintiff and defendant appearances. The firm's public statements confirm it represents patent holders in assertion campaigns as well as companies accused of infringement. This balanced practice includes work for individual inventors, startups, and multinational corporations. The firm has noted it has secured eight-figure damage awards for plaintiff clients and has also won defense verdicts for those accused of infringement, although specific details for these outcomes are not publicly cited.

The firm maintains an active practice before the Patent Trial and Appeal Board (PTAB), defending patents against invalidity challenges in inter partes review (IPR) proceedings. A notable public success includes representing the patent owner Stellar against Motorola, where the firm secured a Director Review of a PTAB decision, which resulted in the vacating of an IPR institution. Key partners and practice leaders frequently named in firm materials and industry directories include Timothy Devlin, who has served as lead counsel in over 200 patent cases, and James M. Lennon.
