June 20 (Reuters) - Microsoft (MSFT.O) has settled a patent infringement lawsuit over its Cortana virtual-assistant technology after losing a $242 million jury verdict in the case last month, according to a filing in Delaware federal court.
Microsoft and plaintiff IPA Technologies told the court on Tuesday that they have resolved the case. U.S. District Judge Richard Andrews dismissed the lawsuit on Thursday.
IPA is a subsidiary of patent-licensing company Wi-LAN, which is jointly owned by Canadian technology company Quarterhill (QTRH.TO) and two investment firms.
Microsoft declined to comment. Attorneys and spokespeople for IPA and Wi-LAN did not immediately respond to requests for comment and more details about the settlement.
IPA filed the lawsuit in 2018, accusing Microsoft of infringing patents related to personal digital assistants and voice-based data navigation. It bought the patents from SRI International's Siri Inc, which Apple acquired in 2010 and whose technology is used in Apple's Siri virtual assistant.
A Delaware jury determined on May 10 that Microsoft owed $242 million for infringing an IPA patent. A Microsoft spokesperson said at the time that the company would appeal the verdict.
IPA has also sued Google and Amazon over its patents. Amazon defeated IPA's lawsuit in 2021. Google has denied IPA's claims, and that case is still ongoing.
The case is IPA Technologies Inc v. Microsoft Corp, U.S. District Court for the District of Delaware, No. 1:18-cv-00001.
