Gunn v. Minton
The Court specified an inquiry for determining whether a state law case related to patents is “arising under” federal jurisdiction. Specifically, the patent issue disputed in the case must be substantial and capable of resolution in federal court without disturbing the federal-state balance approved by Congress.

A patent owner identifying its patent to another party with implicit assertions of the owner’s rights against the party may establish declaratory judgment jurisdiction, especially if patent owner is non-practicing entity.
Innovative Therapies, Inc. v. Kinetic Concepts, Inc.
The Federal Circuit holds that representations to a third party that technological characteristics of a device are similar to an existing patented device and telephone conversations with uninformed, non-decisionmaking employees of the patentee do not create a controversy of sufficient immediacy to warrant declaratory jurisdiction.
Micron Technology, Inc. v. MOSAID Technologies, Inc.
A court has subject matter jurisdiction for a declaratory judgment suit when a patent owner has pursued similar defendants in the past, has publicly stated that they have an aggressive licensing strategy, and has sent a warning letter to potential infringers.
Litecubes, LLC v. Northern Light Products, Inc.
The Federal Circuit addresses the effect of extra-territorial activity by an alleged infringer on subject matter jurisdiction and infringement.
MedImmune, Inc. v. Genentech, Inc.
A licensee is not required to break or terminate a license agreement to create an actual case or controversy prior to seeking declaratory judgment that a patent covered by the license agreement is unenforceable, invalid, or not infringed.
Livorsi Marine Inc. v. Nordskog Publishing Inc.
Plaintiff’s action for declaratory judgment of noninfringement of defendants’ patent is dismissed for lack of justiciable controversy, since parties were engaged in licensing negotiations when plaintiff filed suit, and defendants’ correspondence with plaintiff did not create reasonable apprehension of infringement suit.
