It is said that a patent is only as good as your ability to protect it, so that is what Mid-America Machining (Brooklyn, MI), a designer and manufacturer of blow molds and extrusion blow molds, is doing. On June 15, Mid-America Machining Inc. filed a patent infringement lawsuit in the United States District Court for the Eastern District of Michigan against Milacron Plastics Technologies Group LLC (Cincinnati, OH).
The lawsuit accuses Uniloy, a Milacron unit, of infringing on five of Mid-America's design and utility patents. Uniloy makes competing products (molds and tooling, and machinery) and supplies the same industry as Mid-America. The suit alleges that Milacron's Uniloy division "has placed infringing products into the stream of commerce knowing and intending that this Judicial District was, and is, a likely destination of those products." Mid-America's suit notes that, based on this information, Milacron is making, using, selling, offering to sell, and/or distributing the infringing products "at least to Meijer Inc."
Mid-America's patents concern the "Method and Apparatus for Making a Light Weight Container" and were issued on various dates in 2013 and 2014. They cover "methods and apparatuses for manufacturing light weight, blow-molded containers and the containers themselves."
