Marley Mouldings v. Mikron Industries

Marley Mouldings patented a method of forming plastic products used to replace traditionally wood products, such as door frames, window trim and molding. The C.A.F.C. distinguishes this case from Honeywell v. ITC. The Marley claims are not "insoluably ambiguous" because persons of experience in the field of polymer processing would understand how to measure by volume and convert weight to volume from bulk density data. By comparison, the claims in Honeywell required a specific method of measuring to determine if the measurement was in the claimed range, but such method of measuring was not specified in the Honeywell patent.
