Hoffman Patent Firm

Firm Summary: Hoffman Patent Firm
As of: May 7, 2026

Hoffman Patent Firm is a solo or small intellectual property boutique based in Scottsdale, Arizona, with a national and international practice. The firm is not ranked in major legal directories such as AmLaw or Chambers, which is consistent with its size. The practice is led by its principal, Louis J. Hoffman, a Harvard Law School graduate who previously practiced at the national IP firm Brown & Bain (now part of Perkins Coie). Mr. Hoffman is also an adjunct professor of patent law at Arizona State University.

The firm's practice is centered on patent monetization, including licensing, enforcement, and sales, primarily for patent holders. It serves independent inventors, start-ups, and small to mid-sized companies. This focus is reflected in its litigation history, which, according to available data, is exclusively on behalf of patent plaintiffs. The firm's work in the Almondnet, Inc. v. Microsoft Corporation case indicates experience in complex software and internet advertising technology patents.

The firm's most prominent tracked representation is as lead counsel for Almondnet, Inc. in its patent infringement litigation against Microsoft. This litigation is part of a broader campaign by Almondnet to enforce its portfolio of patents related to targeted online advertising. In related proceedings, the firm has defended its client's patents against validity challenges at the Patent Trial and Appeal Board (PTAB), such as the inter partes review (IPR) filed by Microsoft.

The key attorney and leader of the firm is Louis J. Hoffman. He has been recognized by Intellectual Asset Management (IAM) magazine as a top patent professional. Mr. Hoffman has also been actively involved in patent legislation issues and has held leadership roles in the National Association of Patent Practitioners (NAPP).
