Spectra Logic has thwarted a patent infringement lawsuit brought in July 2012 by Overland Storage. The squabble concerns Overland’s patent on storage library partitioning. This month the patent office appeal board ruled that this was invalid since the claims made in the patent were disclosed as ‘prior art’ in an IBM 3494 tape library manual. The board also disallowed Overland’s attempt to amend its claim. Last year the International trade commission ruled the patent to be invalid. More from Spectra Logic.
