Technology giants have won a lawsuit involving web patents against patent firm Eolas Technology.
The US Court of Appeals for the Federal Circuit upheld a jury ruling in favour of Google, Amazon, JC Penney and Yahoo in 2012, which said that the two patents owned by Eolas and the University of California were invalid.
Eolas had claimed that the tech firms’ functionalities including music clips, search features, maps and embedded applications had used its inventions.
According to Eolas founder Michael Doyle, the infringed patents included inventions that "took the Web from a primitive and static world to today’s seamlessly interactive environment."
The patent firm also included other firms in its original complaint, including Apple, EBay and Citigroup, but most of them were resolved prior to trial.
The Appeal court’s decision follows concerns in relation to unnecessary and perky patent battles by patent trolls, which aim to collect licensing fees and damages from technology firms.
Eolas also settled a similar lawsuit with Microsoft, while it was dismissed on plea for a retrial on the patents’ validity.
