Luckett v. Delpark, Inc.

Background

Philip Luckett, a Connecticut citizen and owner of two patents for undergarments, sued two companies that had licensed or been assigned rights to his patents. He filed in the District of New Jersey, claiming the companies had refused to pay royalties, had suppressed sales of a particular garment, and had breached conditions that would restore his title to one patent. His bill asked for accounting of sales, access to books, cancellation of licenses, reassignment of the patent, and injunctions against making or selling the garments.

Reasoning

The narrow question was whether this lawsuit “arises under” the patent laws so it could be heard in federal court. The Court held the suit was mainly about enforcing contracts and collecting royalties, not about vindicating patent rights on their own. The opinion explained that when a patentee’s bill seeks equitable relief tied to license or assignment contracts (forfeiture, royalties, reconveyance), it is essentially a contract case, not a federal patent case. The Court relied on earlier decisions showing that only suits that plainly seek relief for infringement under the patent laws qualify for federal patent jurisdiction.

Real world impact

As a result, disputes where a patent owner primarily seeks contractual remedies—royalties, cancellation of licenses, or title restoration—cannot be converted into a federal patent case simply by adding claims about possible future infringement. Those contract-centered claims must proceed in the proper district or state forum. The decision affirms dismissal for lack of federal patent jurisdiction and is not a final ruling on the underlying contract or patent merits.
