Earlier this month, the Patent Trial and Appeal Board (PTAB) returned final written decisions in two inter partes reviews (IPRs) filed by Apple against patents held and asserted by Parus Holdings, Inc. No challenged claim was cancelled in either proceeding. Now, Parus has filed a second suit against Apple (6:21-cv-00968), again targeting devices that support the Siri virtual assistant, in particular its return of audio messages with results acquired from various websites in response to a verbal request. The first case against Apple was filed as part of a pack of summer 2019 suits, one filed against each of Alphabet (Google), Amazon, Apple, LG Electronics (LGE), and Samsung, subsequently stayed to await the results of these two IPRs, as well as two others, which remain pending.
