The Federal Circuit affirmed the rejection of Jeffrey Hubbell's patent application for obviousness-type double patenting due to distinct inventive entities, emphasizing that this doctrine aims to prevent multiple infringement suits. Additionally, in Aristocrat Technologies v. International Game Technology, the court vacated a summary judgment on indirect infringement due to a recent ruling in Akamai, which clarified inducement liability. The Supreme Court ruled in Kirtsaeng v. John Wiley & Sons that the 'first sale' doctrine applies to copies of copyrighted works lawfully made abroad, overturning lower court decisions that disallowed this defense.
