Interferences


Filter Results



Morrison & Foerster offers clients an intellectual property practice that is unrivaled in its depth of experience, industry and technical expertise, and international scale.

 

One of our many strengths is our experience in the area of patent interferences. These adversarial proceedings before the USPTO determine priority in the case of competing patent applications. Patent interference proceedings can be effective and cost-efficient alternatives to patent litigation.

 

We handle interference actions for a wide range of clients in industries where intellectual property is particularly valuable.

 

Our patent specialists bring substantial expertise in fields such as biotechnology, chemical technology, communications, electronics, medical devices, pharmaceuticals, and software. Our clients include Chiron, Centacor and DePuy Orthopedics (Johnson & Johnson affiliates), Eiken Chemical Company, the Johnson & Johnson Consumer Products Company, and the University of California.

 

We are a pioneer in blending litigation attorneys and patent prosecutors to handle interferences, and we are one of a handful of firms with extensive experience in this adversarial action in the USPTO. Our experience includes leadership roles in the Interference Bar, and experts who regularly lecture on the latest developments in interference law.
