The process normally begins with a review of the relevant documents and deadlines. Depending on the matter, these may include a foreign priority application, PCT publication, international search report, written opinion, existing claims, drawings, prior USPTO correspondence, and instructions from foreign counsel.

After the scope of work is defined, Mattis IP provides an engagement agreement and, for many services, a flat-fee proposal. Drafts and recommended filing or prosecution strategies are then shared electronically for review. Communications can be handled directly with the client, through foreign counsel, or through a coordinated combination of both. Mattis IP aims to provide clear U.S.-practice guidance, responsive communication, and efficient handling across time zones.
