Microsoft must pay patent owner IPA Technologies $242 million, a federal jury in Delaware said on Friday after determining that Microsoft's Cortana virtual-assistant software infringed an IPA patent.
The jury agreed with IPA after a week-long trial that
Microsoft's voice-recognition technology violates IPA's patent rights in
computer-communications software.
IPA is a subsidiary of patent-licensing company Wi-LAN,
which is jointly owned by Canadian technology company Quarterhill and two
investment firms. It bought the patent and others from SRI International's Siri
Inc, which Apple acquired in 2010 and whose technology it used in its Siri
virtual assistant.
“We remain confident that Microsoft never infringed on IPA’s
patents and will appeal,” a Microsoft spokesperson said.
Representatives for IPA and Wi-LAN did not immediately
respond to a request for comment on the verdict.
IPA filed the lawsuit in 2018, accusing Microsoft of
infringing patents related to personal digital assistants and voice-based data
navigation.
The case was later narrowed to concern one IPA patent.
Microsoft argued that it does not infringe and that the patent is invalid.
IPA has also sued Google and Amazon over its patents. Amazon
defeated IPA’s lawsuit in 2021, and the Google case is still ongoing.
