Russia's Kaspersky Lab anti-virus software developer has won a lawsuit against U.S.-based IPAT, which accused the Russian leading anti-virus company of breaching its patents, Kaspersky Lab head Yevgeny Kaspersky wrote in his blog on Livejournal.com on Tuesday.

“A court in the Eastern District of Texas has passed its ruling on a lawsuit filed by IPAT, fully lifting all accusations from us. Importantly, the court ruling bears WITH PREJUDICE mark, which means IPAT will be unable to file a lawsuit on these patents again!” Kaspersky wrote.

According to Kaspersky, in 2008 IPAT filed two patent lawsuits against the Lab and another 34 companies, including Symantec, Sophos, McAfee, F-Secure, CA, Trend Micro, Novell, Eset, Microsoft and others.

The U.S. firm accused the defendants of violating its patents describing methods for limiting the launch of software programs.

The court win has cost Kaspersky Lab three and a half years of work and $2.5 million in legal fees, Kaspersky said.

There is a whole industry of so-called patent trolls in the United States, which take advantage of the U.S. patent legislation to patent a broad, unrealized, idea instead of a developed invention and then sue others over allegedly breaching their patent rights, Kaspersky said.

Kaspersky Lab was the only one of 35 companies which brought a lawsuit against IPAT and refused to sign an amicable agreement and pay alleged indemnities, Kaspersky said.
