Microsoft Ordered To Pay IPA Technologies $242 Million In Cortana Patent Lawsuit

After finding that Microsoft’s Cortana virtual assistant software violated an IPA patent, a federal jury in Delaware on Friday, May 10, ordered the company to pay $242 million to the patent owner, IPA Technologies.

After a trial that lasted a week, the jury found in favor of IPA, finding that Microsoft’s voice recognition technology infringes on IPA’s patent rights in computer communications software.

IPA is a division of Wi-LAN, a patent licensing business that is controlled by two investment firms and the Canadian technology company Quarterhill.

It purchased the patent along with others from Siri Inc., a company run by SRI International, which Apple purchased in 2010 and utilized technology from for its Siri virtual assistant.

A Microsoft representative stated, “We remain confident that Microsoft never infringed on IPA’s patents and will appeal.”

An inquiry regarding the verdict was not immediately answered by IPA or Wi-LAN representatives.

2018 saw the filing of the case by IPA, which charged Microsoft with violating patents pertaining to voice-activated data navigation and personal digital assistants.

Subsequently, the case was limited to one IPA patent.

Microsoft claimed that the patent is invalid and that it does not infringe.

In relation to its patents, IPA has also sued Google and Amazon. In 2021, IPA’s lawsuit was defeated by Amazon, and the Google case is still pending.
