Review Of 2015 Federal Circuit Decisions Addressing IPR Claim Construction And Procedural Issues

The court further explained that there are indeed limits to the broadest reasonable interpretation standard, by adding[t]hat is not to say, however, that the Board may construe claims during IPR so broadly that its constructions are unreasonable under general claim construction principles. Thus,[t]he protocol of giving claims their broadest reasonable interpretation...
