Is Microsoft Liable for $242 Million Over Patent Infringement?

Updated: May 15


Microsoft has been ordered to pay $242 million to IPA Technologies for infringing on an IPA patent with its Cortana virtual assistant, according to a federal jury in Delaware. The jury found that Microsoft's voice recognition technology violates IPA's patent related to computer communication software.

IPA Technologies is a subsidiary of Wi-LAN, jointly owned by Canadian tech company Quarterhill and two investment firms. Microsoft maintains it did not violate IPA's patents and plans to appeal the verdict.

IPA filed the lawsuit in 2018, accusing Microsoft of infringing patents related to personal digital assistants. Microsoft argues the patent is invalid. IPA has also sued Google and Amazon for similar issues; Amazon won its case in 2021, while the Google case is still ongoing.
