A US court has upheld a decision to invalidate a tech firm's claim to own technologies underpinning the web.
Eolas's claims revolved around a series of patents it had been using to extract licence fees from hi-tech firms such as Microsoft and Oracle. However, Eolas's claims were disputed by many others including web creator Sir Tim Berners-Lee. The ruling will also mean an end to many other lawsuits Eolas mounted against hi-tech firms.
A US Appeals court in Washington has upheld a decision made in Texas in February 2012 that initially invalidated Eolas's patents.
Sir Tim Berners-Lee testified at that original Texas trial and said that if Eolas's patent claims were upheld it would "substantially impair the usability of the web". The broad patents cover many familiar features of webpages including playing videos, responding to user input and manipulating images. U.S. Court Rules Disputed Web Patent Claim Is Invalid [bbc.co.uk]
