USPTO Interference

Orrick IP lawyers, who were recently named as an "IP Group of the Year" by Law360, are experienced at all phases of interference practice, including preliminary motions, pre-interference prosecution strategy, evidence preparation during the testimony phase, evidentiary motions, final briefing, and fact and expert witness preparation in the interference proceedings. Because interferences are highly specialized proceedings, combining substantive elements of patent prosecution and patent litigation, Orrick’s significant litigation experience combined with patent prosecution expertise brings all the necessary skills together to successfully represent clients at all stages of an interference.
