Last week, the Federal Circuit Court of Appeals reversed the Patent Trial and Appeal Board (PTAB) invalidity findings on three LBT IP I LLC patents and vacated its invalidity decision on a fourth patent, and remanded it for further proceedings. The court ruled that the PTAB wrongly found that Apple had shown that four of five challenged claims of battery conservation patents of LBT it was accused of infringing are invalid. Taft IP litigation attorneys Brian Seal and Shaun Gregory represented LBT.

The suit was initially filed in 2019 by LBT, alleging all of Apple’s products with power-saving features, including iPads and iPhones, infringe five patents. The case is LBT IP I LLC v. Apple Inc., 22-1613, in the U.S. Court of Appeals for the Federal Circuit. The underlying infringement case is LBT IP I LLC v. Apple Inc., case number 1:19-cv-01245, in the U.S. District Court for the District of Delaware.
