Disaster recovery and virtualisation management software maker, Veeam Software declared victory and an end to three year lawsuit with security giant Symantec.
Symantec had claimed infringements of data storage, restore and backup patents.
The three year legal battle started when Symantec filed two separate lawsuits in 2012 with the US District Court in the Northern District of California over patent infringement by several Veeam products.
Veeam said that the US Patent & Trademark Office (USPTO) has invalidated all the remaining patent claims by Symantec.
USPTO has invalidated seven of Symantec‘s patent claims by saying they were obvious or anticipated by prior art.
Veeam claims that the Symantec’s physical backup products could not compete with its products that deliver availability solutions for the modern data centre.
Veeam CEO Ratmir Timashe said: "These final USPTO decisions mean Symantec can never again assert these patents against Veeam’s products.

"We are delighted with the USPTO’s decisions, which are a testament that the U.S. patent system does not protect patents that do not represent authentic innovation."
