Geo M. Martin, Co. v. Alliance Mach. Sys. Int'l., LLC., 09-1132, concerned a challenge to the district court's ruling as a matter of law that the '566 patent would have been obvious at the time of invention, in a suit for infringement of a patent, relating to an improvement over the traditional bundle breaker (a machine used to separate stacked sheets of corrugated board). In affirming, the court held that the district court correctly concluded as a matter of law that the difference between the prior art and the claimed improvement were minimal. Also, the district court correctly concluded that evidence of secondary considerations in this case do not create a reasonable dispute as to obviousness. Lastly, because the asserted claims of the '566 patent are invalid, remaining issues are moot.
