SCA Hygiene Products Aktiebolag (SCA) (plaintiff) brought suit against First Quality Baby Products, LLC (First Quality) (defendant). SCA claimed that First Quality infringed on a patent owned by SCA. First Quality argued that laches prevented SCA from recovering for the alleged infringement, even though SCA filed its complaint within the relevant statute of limitations. First Quality claimed that the relevant section of the Patent Act, § 286, was not a true statute of limitations because it ran backward from the time of suit. First Quality also argued that the application of a true statute of limitations considers the fairness of permitting adjudication. According to First Quality, the accrual of a claim occurs when a plaintiff knows of a cause of action. First Quality was granted summary judgment by the trial court on the grounds of laches. The decision was affirmed by the appeals court. The Supreme Court then granted certiorari.
