Co-founder of Microsoft Paul Allen has re-filed a patent infringement lawsuit against several tech organisations, including Google.

Mr Allen submitted his amended suit to a judge in Seattle yesterday (December 28th) after a previous attempt was dismissed on December 10th for being too vague.

He claims 11 companies, including Google, Facebook, Yahoo! and Apple infringed on patents held by his now-defunct firm Interval and has now provided additional information on exactly what products and services he believes violate his copyright.

Some of the technologies Mr Allen alleges use his patents include several features used by internet marketing services and search engines, with the Seattle Times reporting it includes "systems that automatically call up and display related content".

Although the publication stated his case is a "long shot", it could be worth up to $500 million (£324.9 million) if it is successful.

As well as co-founding Microsoft, Mr Allen is estimated to have given over $1 billion to various philanthropic causes.
