When Does a Non-Compete Clause Constitute Patent Misuse?
Businesses manufacturing and selling patented goods should consider the recent Seventh Circuit decision in County Materials Corporation v. Allan Block Corporation, 2007 WL 2701979 (7th Cir. 2007), where the court tackled several important issues related to non-compete covenants in agreements concerning the manufacture and sale of patented goods, including jurisdiction, patent misuse, and enforceability under the state’s laws. Of particular importance is the court’s discussion of when the provisions of a covenant not to compete constitute patent misuse.
County Materials manufactures concrete blocks, and Allan Block develops, markets, and licenses technology for the manufacture of concrete blocks. The parties entered into an agreement granting County Materials the exclusive right to manufacture Allan Block’s patented block products in northwest Wisconsin. County was granted the right “to sell these products under the Allan Block trademark.” The agreement also allowed County Materials to make and sell two specific competing block products, without time restrictions. It also specified that the 18 months following termination of the agreement, County Materials could not “directly or indirectly engage in the manufacture and/or sale of any other [competing]… block.”
Allan Block notified County Materials that it would be terminating the agreement. County Materials soon completed its own competing new design of concrete block. When County Materials began taking steps to produce the block, Allan Block threatened to sue for a violation of the non-compete clause in the agreement. County Materials beat them to court, filing a declaratory judgment action seeking a declaration that the non-compete provision of the parties’ agreement constituted patent misuse and was therefore void. The federal district court found that the non-compete clause did not violate federal patent policy or Minnesota law.
The United States Court of Appeals for the Seventh Circuit affirmed. The Seventh Circuit reviewed three issues: 1) whether this case involved question of federal patent law and should therefore be decided by the Federal Circuit, 2) whether the non-compete clause constituted patent misuse, and 3) whether the non-compete clause violated Minnesota state law. First, the court held that it was proper for it to hear the appeal because the question presented was merely one of the contractual enforceability of a non-compete clause, rather than a question of federal patent law.
The court went on to reject the claim that the non-compete clause constituted patent misuse. County Materials argued that the inclusion of the non-compete clause in the patent license was per se unlawful patent misuse and the improper result of patent leverage. Under current law, however, such per se claims are rarely recognized unless the patent owner has market power or the provisions of the non-compete clause were not reasonably within the patent grant. The court instead applied the rule of reason to County Materials’ claim that the clause was unreasonable because it allowed Allan Block to use its patent to exclude the competition in the market from unpatented products. The court concluded that the plaintiff failed to show that the non-compete clause had any effect on the broader market for concrete blocks, rather than just impacting the plaintiff. In rejecting the patent misuse allegation, the court also noted that the non-compete clause was subject to temporal and geographic limits and permitted County Materials to sell and manufacture two competing products. The court also determined that the non-compete clause did not violate Minnesota state law, finding that the agreement was reasonable particularly in light of the exclusivity provisions, explaining that that “when a licensee gets an exclusive patent license… it is benefitting from the patentee’s property rights more than it would with a non-exclusive license.”
