First Means First: Dismissal of Prior Related Actions No Cure For Relator’s First-to-File Defect

The Fourth Circuit held in United States ex rel. Carter v. Halliburton – its third decision in this protracted litigation – that the False Claims Act’s first-to-file rule required dismissal of the relator’s action, because relator brought his case while related cases were pending even though those related cases had since been dismissed and the relator’s complaint subsequently amended. The court explained that the statutory text of the first-to-file rule is “unambiguous” and “affords courts no flexibility to accommodate an improperly-filed action when its earlier-filed counterpart ceases to be pending.” The court acknowledged that its holding “may raise statute of limitations problems” for some FCA relators, but noted that (1) the FCA’s objective of putting the government on notice of fraud was already met by the first-filed actions, and (2) FCA defendants also have an interest “in repose and avoiding stale claims outside the limitations period.”

Claim construction is a key stage of most patent litigations, where the court must decide the meaning of any disputed terms in the patent claims. Generally, claim terms are given their plain and ordinary meaning except under two circumstances: (1) when the patentee acts as its own lexicographer and sets out a definition for the term; and (2) when the patentee disavows the full scope of the term either in the specification or during prosecution. Thorner v. Sony Comput. Ent. Am. LLC, 669 F.3d 1362, 1365 (Fed. Cir. 2012). The Federal Circuit’s recent decision in Aortic Innovations LLC v. Edwards Lifesciences Corp. highlights that patentees can act as their own lexicographers through consistent, interchangeable usage of terms across the specification, effectively defining terms by implication.
