In Uniloc 2017 LLC v.
Uniloc's patent,
On appeal, Uniloc argued that the PTAB's decision rested on an incorrect construction of the term "intercepting." The Federal Circuit rejected Uniloc's argument that the construction was erroneous because it would encompass a situation where messages are sent intentionally to an intermediary recipient. The Court found that the PTAB's construction was supported by the intrinsic evidence, including the specification and prosecution history, and that this evidence outweighed Uniloc's reliance on dictionary definitions. The Court also affirmed the PTAB's holding that Apple failed to establish that claims 18-22 of the '552 were invalid.
