Post Grant Practice

Litigation at the Patent Office

The face of patent litigation is changing, and RatnerPrestia’s attorneys are at the forefront of that change. There is a significant chance that all or part of your patent infringement battle will be waged at the Patent Office. Post grant proceedings—including inter partes review, post grant review, covered business methods—can resolve the issue of patent validity faster than district court litigation and at a fraction of the cost. RatnerPrestia is adept at representing patent challengers (petitioners) and owners alike in these proceedings. Read More
