From the Opinion

The passage below is extracted verbatim from the opening of the document. It has not been editorially summarized — consult the full opinion for the court's complete reasoning.

The present appeal arises from the dismissal of a d e- claratory judgment action in the Southern District of Florida. Allied Mineral Products, Inc. (“Allied”) sued three related entities, OSMI, Inc., Stellar Materials, Inc. , and Stellar Materials, LLC (collectively “Stellar”), seeking a declaratory judgment that it did not infringe Stel lar’s U.S. Patent No. 7,503,974 (the “’974 patent”) , the patent is invalid, and Stellar committed inequitable conduct. The district court dismissed the complaint for lack of subject matter jurisdiction.
