Scott McKeown on Which Comes 1st: The USPTO or the Court?

The hierarchy of the U.S. court system is well established, but recent patent law cases have challenged this hierarchy with the power of government agency – the USPTO to be exact. Scott McKeown, Partner at Oblon, Spivak, Practice Center Contributor and author of Patents Post Grant Blog, recently wrote two articles concerning the USPTO’s reexamination process and how its parallel nature to patent infringement cases resulted in conflict that’s occurred with the U.S. Court of Appeals of the Federal Circuit (CAFC) as well as with the U.S. District Court in the District of Connecticut. Scott explains the patent law issue:

Patent reexamination is often initiated in parallel with an ongoing infringement litigation. In the case of a parallel inter partes proceeding (IPX), the first of the proceedings to conclude (litigation or IPX) controls the outcome of the other by operation of statutory estoppel. As such, a final holding in the parallel court proceeding will end an ongoing IPX. Moreover, the losing party would be precluded from seeking IPX at a later date.

On the other hand, ex parte patent reexamination (EXP) has no such statutory “shut off valve.” Thus, even a party that was bound by IPX estoppel could file a request for ex parte patent reexamination. In this way, the infringer could attempt to “undo” the effect of the earlier, final, court judgement by invalidating the patent via the EXP filing. (more…)
