Justia Patents Opinion Summaries

The Tennessee holder of a patent on a pet-access door received communications from a New Jersey company concerning cooperative marketing of a portable pet-access door, but did not respond until the New Jersey company indicated that it had obtained patent 141. The companies negotiated; the owner of the New Jersey company traveled to Tennessee to demonstrate the product and the parties signed a non-disclosure agreement, with a provision identifying Tennessee as the forum of any litigation. When the Tennessee company sought a patent on a similar item, the New Jersey company claimed infringement. The Tennessee district court dismissed an action seeking a declaration of noninfringement and of invalidity of patent 141. The Federal Circuit affirmed, finding that the court lacked personal jurisdiction over the New Jersey defendant. Only activities of the patentee relating to enforcement or defense of the patent, not actions relating to commercialization, give rise to personal jurisdiction in a declaratory judgment action. The New Jersey company's efforts to interest the Tennessee company in its product were insufficient to vest jurisdiction; the New Jersey company's only activities relating to enforcement consisted of correspondence. The suit did not arise from the non-disclosure agreement.
