A group of companies including Apple, Microsoft and BlackBerry have filed legal proceedings against Google over claims it is abusing patents they jointly acquired as part of a consortium called Rockstar.
The patents were previously owned by the defunct telecoms outfit Nortel and came up for auction in 2011. At the time Apple, Microsoft BlackBerry and Sony teamed up to defeat Google, with a winning bid of $4.5bn for access to its 4,000-strong patent book.
Now, the consortium is suing Google as it claims seven patents within the portfolio are being infringed by the firm relating to its search and advertising keyword technologies.
"Despite losing in its attempt to acquire the patents-in-suit at auction, Google has infringed and continues to infringe," the court filing reads.
The firms are seeking costs relating to damages caused by the infringements of these patents as well as, “other costs and further relief as the Court may deem just and proper”.
V3 contacted Google for its response to the filing but had received no reply at the time of publication.
The filing underlines the continued patent wars in the technology industry. Despite dying down somewhat in 2013 after a hectic 2012, there are still many cases rumbling on as firms seek to gain any advantage over each in the marketplace.
