Plaintiff's "allegation that if [plaintiff] cease[d] making royalty payments under [a license agreement], ' [defendant] would bring suit against [plaintiff] for infringement and injunctive relief” was sufficient to create a substantial controversy at the pleading stage even though defendant "advised [the declaratory judgment plaintiff] in writing that [defendant] did not 'presently intend' to terminate [a license agreement]."
