About me

Patrick started Richards Patent Law after spending over eight years with McDermott Will & Emery LLP, a large general practice firm in Chicago where he concentrated his practice on patent prosecution, counseling, opinion work and litigation.

Utilizing his strong technical background, Patrick has experience in all phases of utility, design and PCT patent prosecution in many technical fields, including the areas of mechanical, electrical, computer systems, chemical and financial products technologies.

In addition to his extensive patent prosecution experience, Patrick has counseled numerous clients on matters concerning: patent portfolio acquisition and management; patent portfolio licenses, sales and purchases; joint development agreements; freedom to practice opinions; patentability opinions; non-infringement opinions; and employment and non-compete agreements.
