Apple has updated an earlier lawsuit filed against Samsung with claims that the Galaxy S4 and its Google Now feature violate two Apple patents covering functions of its own virtual personal assistant, Siri. Florian Mueller of FOSS Patents relayed news of the updated complaint on Wednesday, and he noted that two of the patents — U.S. Patent 8,086,604, and U.S. Patent 6,846,959 — cover technologies related to Siri. Both filings describe a “universal interface for retrieval of information in a computer system.” Apple also added three more patents to its earlier complaint that are not related to Siri, according to the report.
