In a ruling this week that will cheer up patent trolls, the Supreme Court said patent owners can lie in wait for years before suing. This will allow trolls to sit around while others independently develop and build technology. The troll can then jump out from under the bridge and demand payment for work it had nothing to do with.

The 7-1 decision arrives in a case called SCA Hygiene v. First Quality Baby Products. This case involves a patent on adult diapers but has a much broader reach. The court considered whether the legal doctrine of "laches" applies in patent cases. Laches is a principle that penalizes a rightsholder who "sleeps on their rights" by waiting a long time to file a lawsuit after learning of a possible infringement. It protects those that would be harmed by the assertion of rights after a lengthy delay. For example, laches would work against a patent owner that saw an infringing product emerge yet waited a decade to sue, after significant investment of time and resources had been put into the product.

The ruling in SCA follows a similar decision in Petrella v. MGM holding that laches is not available as a defense in copyright cases. The Supreme Court has generally rejected "patent exceptionalism" and has often reversed the Federal Circuit for creating special rules for patent law. So this week's decision was not especially surprising. In our view, however, there were compelling historical and policy arguments for retaining a laches defense in patent law.
