In September, a pair of inter partes reviews (IPRs) filed by Apple against patents held and asserted by Parus Holdings, Inc. left all challenged claims standing. However, this past week the Patent Trial and Appeal Board (PTAB) nixed claims from the same two patents, this time challenged in petitions filed jointly by Alphabet (Google), LG Electronics (LGE), and Samsung. Key to these final written decisions were Parus’s failures to adequately push certain invention dates back and to find support in earlier written descriptions for later claims, each failure expanding the universe of prior art available to the petitioners. Meanwhile, in district court a few days earlier, Parus sued Samsung (6:21-cv-01073) for a second time over patents from the same family.
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.
Among patent assignments recently made public by the USPTO is the transfer of more than two dozen assets generally related to speech recognition and/or processing from Nuance Communications to a Delaware LLC. The transaction, dated January 1, 2021, followed by two and a half months the execution of an assignment of two US patents, also broadly directed to speech recognition, to the same LLC from another player in the space. This collection of similar assets suggests that additional patent cases may be on the verge of joining a slew of speech recognition campaigns spread out across nearly all stages of the litigation life cycle.

Its 2019 suits stayed to await the outcome of several inter partes reviews (IPRs) of the patents there in suit, Parus Holdings, Inc. has sued prior defendant Alphabet (Google) (6:21-cv-00570) and new defendant Microsoft (6:21-cv-00571), asserting overlapping subsets of three patents from the same family. The plaintiff again targets the provision of products that feature virtual assistants: for Google, the incorporation of Google Assistant in its various Chromecast, Fitbit, Google Glass, Nest, Pixel, and Stadia products; and for Microsoft, the incorporation of Cortana in its Microsoft Surface, Microsoft Windows 10, and Microsoft Windows 10 Mobile products.
