Masephol v. Weyerhaeuser Co., No. 16-2377 (7th Cir. 2017)Annotate this Case
In 1952, the patent for a “Composite Fire Door,” issued to Owens‐Illinois. The patent claims never specifically mention asbestos, but describe a fire door with a “core of inorganic, rigid, fireproof, lightweight material of a substantially uniform apparent density and consistency throughout.” In 1956, Owens‐Illinois licensed the patent to Weyerhauser’s predecessor. Until 1978, its Marshfield, Wisconsin plant produced fire doors that used asbestos as a thermal insulator. The plaintiffs were all employees of that Marshfield plant and developed mesothelioma as a result of asbestos exposure. The Seventh Circuit affirmed the dismissal of their claims as covered by the exclusive remedy provisions of Wisconsin’s Worker’s Compensation Act, Wis. Stat. 102.03(2). The court rejected an attempt to avoid that bar by recharacterizing their injuries as occurring off the job based on a “public nuisance” theory involving ambient asbestos. The court characterized the claims against Owen‐Illinois claims as frivolous.
