Court of Appeals for the Seventh Circuit August 31, 2004, 03-4247 (Thomas Hinc v. Lime-O-Sol Company)

KANNE, Circuit Judge.

Thomas Hinc, a resident of Illinois, sued Lime-O-Sol Company (“LOS”), an Indiana corporation with its headquarters in Indiana, for breach of contract. Holding that LOS’s contractual obligation to use its “best efforts” to market the product developed by Hinc was too vague to be enforceable, the district court granted summary judgment in favor of LOS. Hinc appeals. We reverse.
