"In an increase over prior terms, the Supreme Court of the United States issued six opinions involving patent law during its October 2016 Term. These decisions addressed issues ranging from patent exhaustion, multicomponent products, and biosimilar patents to procedural issues like venue and the statute of limitations for infringement claims. The increase in patent cases heard by the High Court coincides with an apparent increase in patent litigation generally. As observed by Judge Kathleen O'Malley of the U.S. Court of Appeals for the Federal Circuit (Federal Circuit), the court that has exclusive jurisdiction over most appeals involving patents: 'While federal filings in complex civil cases in regional circuits have been down in recent years, the patent litigation business is booming. Indeed, patent filings in district courts have almost doubled from 2010--when there were 3,301 patent actions filed--to 2013, when ... there were 6,497 such cases instituted.'"
