Around this time last year, RPX flagged the movement of a portfolio from Nuance Communications to a Delaware LLC. Generally related to speech recognition and/or processing, the portfolio has changed hands again, landing with yet another Delaware NPE (one that, according to public records, may have recently procured funding).

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.
