Finally a patent judge making some sense. A federal judge has ruled that mathematical algorithms can not be patented, meaning that the lawsuit against Rackspace is no longer valid. Uniloc USA sued Rackspace saying that the processing of floating point numbers via the Linux operating system violated their patent.
Chief Judge Leonard Davis cited a ruling by the US Supreme Court in which they determined that mathematical algorithms cannot be patented.
Rob Tiller, Red Hat's Assistant General Counsel for IP:
NPE patent lawsuits are a chronic and serious problem for the technology industry. Such lawsuits, which are frequently based on patents that should never have been granted, typically cost millions of dollars to defend. These suits are a plague on innovation, economic growth, and job creation. Courts can help address this problem by determining the validity of patents early and with appropriate care. In this case, Judge Davis did just that, and set a great example for future cases.
Red Hate defended Rackspace in the matter because they supply Linux to Rackspace. Red Hat has a history of standing behind customers.
