Firm Profile

DigiPat service provides patent copies, US and foreign file histories, and special PTO documents on request.
With one of the industry’s largest collections of File Histories, our experienced staff at the United States Patent & Trademark Office (USPTO), and our international alliances, we are able to supply both US and foreign documents quickly to our clients.


DigiPat was founded in the early 90’s by patent lawyers on the premise that the legal community was underserved with respect to being able to obtain patent and trademark documents, as well as the related file histories, in a manner to meet their specific needs. As practicing patent attorneys we understand the need for thoroughness, efficiency and timeliness, so we have focused DigiPat on delivering user-friendly documents as quickly as possible.

DigiPat’s staff has over 75 years of collective experience in working with the USPTO and providing document services to the legal community. This experience provides our clients with virtually every possible advantage when you need documents from or on-site representation at the USPTO. Further, this experience allows DigiPat a multi-level review process – rather like a partner review at a law firm to ensure client’s needs are met.

We have recognized that the world is getting smaller and this creates the related need to access patent or trademark information on a global basis. To that end, we have established correspondent alliances in the major international patent centers for Europe, Canada and Japan. Through our correspondents, we provide our clients with documents from and representation at the headquarters of the majority of the world’s patents.

Using Defensive Publication to control patent costs
Defensive publication is a cost effective way to stop others patenting an invention.  The concept is simple; by publishing details of an invention, you create prior art, proving the invention is no longer novel and stopping others from patenting the idea.
The strategy does not give the same monopoly benefits as a patent but at a fraction of the cost and time it provides ‘Freedom to Operate’ i.e. you know that you can continue using your invention without the risk that someone will later patent the same concept.

This presentation uses two case studies to demonstrate how Defensive Publication can work as part of your strategy to further protect your inventions while lowering your costs.
