Ericsson has agreed to resolve an intellectual-property dispute with software maker Airvana Networks Solutions, which alleged that the wireless network maker is developing products based on its patented technology.

In February 2012, Airvana sued Ericsson for about $330m and accused it of developing software based on Airvana’s patented technology and deploying it for operating wireless network equipment to prevent paying license fees.

According to the court filings, Ericsson revealed that the resolution is ‘complicated’, with details still being negotiated, Bloomberg reported.

Both the companies agreed to settle the dispute in principle following a mediation on May 9.

The court earlier established that all of the EV-DO products marketed and sold by Ericsson were subject to the preliminary injunction motion as per Airvana hardware design.

Subsequently, in March 2013, Justice Barbara Kapnick granted Airvana a preliminary injunction barring Ericsson from ‘using, operating, testing or deploying’ certain hardware but allowing it to use Airvana licensed software.
