Vringo sues Microsoft alleging violation of search patents

Google and AOL also scrutinised

Vringo's subsidiary firm I/P Engine has filed a lawsuit against Microsoft in the Southern District of New York claiming that the software major has infringed two of its patents.

The patents are US Patent No. 6,314,420 and U.S. Patent No. 6,775,664 which allegedly enable its Bing Internet search engine to most efficiently display advertisements for its users.

I/P Engine is seeking damages through royalties and "any form of recoverable economic injury."

I/P Engine, in November 2012, received about $30m as damages from companies Google and AOL which had copied the same patents that are at currently the issue in the Microsoft suit.

One of the patents is considered to be referenced by the US Patent and Trade Office in 2003, when the agency discarded a similar Microsoft patent application.

In August 2012, Vringo sold off 9.6 million shares of its common stock for over $31m to purchase 500 patents and patent applications from Nokia, while it later sued Chinese mobile maker ZTE in the UK for allegedly abusing using these patents.

According to reports, I/P Engine had been seeking damages of no less than $696m.
