A patent troll that accused Rackspace of violating a patent merely by selling Linux-based servers has seen its case thrown out. A judge ruled the patent claim invalid because it describes a relatively simple math operation.
The company in question is Uniloc, which has a long history of suing tech vendors. In 2009, a US District Court judge overturned a $388 million verdict Uniloc had won against Microsoft. That litigation was finally settled late last year for an undisclosed sum. Uniloc continues litigating, however, with at least a dozen lawsuits filed just last week.
Uniloc sued Rackspace in June 2012 in US District Court in Eastern Texas (PDF), claiming Rackspace violated its patent "by or through making, using, offering for sale, selling and/or importing servers running Linux Kernel (version 2.6 or higher), which is used to process floating point operations carried out on Rackspace’s servers including those servers used in conjunction with Rackspace’s hosting solutions/products."
