In Kimble v. Marvel Enterprises, citing stare decisis, the Court held that a patent holder cannot charge royalties for the use of his invention after its patent term has expired. In so holding, the Court affirmed a 60 year-old case along the same lines. But in yesterday’s decision, three justices dissented, stating that “[t] he Court employs stare decisis, normally a tool of restraint, to reaffirm a clear case of judicial overreach.” Should the Court have reversed course?
