The Association of Intellectual Property Firms (AIPF) is an international association of independent specialty law firms that devote a majority of their practice to intellectual property law. Membership is by firm, creating opportunities for attorneys and professionals within member firms to connect, collaborate, and develop relationships with colleagues around the world.

AIPF membership provides access to programs, resources, and opportunities designed specifically for intellectual property practitioners and boutique law firms.

To be eligible for AIPF membership, a law firm must specialize in intellectual property law and meet one of the following criteria:

• At least 50% of the firm's attorneys are registered to practice before the United States Patent and Trademark Office or before their home country's Patent and Trademark Office; or
• Although fewer than 50% of the firm's attorneys are registered before their Patent and Trademark Office, the firm devotes a majority of its practice to intellectual property law.

Memberships are generally by firm rather than by individual. AIPF also offers Emeritus memberships for attorneys who have retired from member firms and Academic memberships for law professors, students, and others in the legal education community.
