June 5 (Reuters) - Amazon AMZN.O has settled a lawsuit by insurance company State Farm accusing the e-commerce giant of copying its patented technology to develop elder care services for Amazon's virtual assistant Alexa, according to a filing in Delaware federal court.

The companies asked the court on Wednesday to dismiss the case with prejudice, which means it cannot be refiled. State Farm said in a statement on Thursday that the case had been settled under confidential terms.

Spokespersons and attorneys for Amazon did not immediately respond to a request for comment on Thursday.

Bloomington, Illinois-based State Farm sued Amazon in 2022, in what the insurance company said was its first-ever patent infringement lawsuit. According to the complaint, State Farm met with Amazon in 2019 and 2020 about incorporating its Sundial senior-care assistance technology into Alexa-enabled devices.

The lawsuit had accused Amazon of copying patented Sundial features, including its "circle of friends" for coordinating caregiver responsibilities, a chatbot for seniors to interact with the platform, and check-in and monitoring services.

Amazon had denied the allegations and argued that the patents were invalid.

The case is State Farm Mutual Automobile Insurance Co. v. Amazon.com Inc, U.S. District Court for the District of Delaware, No. 1:22-cv-01447.

For State Farm: Michael De Vries, Adam Alper, Akshay Deoras, Kat Li and Leslie Schmidt of Kirkland & Ellis

For Amazon: Doug Lumish of Latham & Watkins, Adam Greenfield of White & Case
