Mechanical Arts

Patterson Belknap attorneys have substantial experience in representing clients in the mechanical arts and manufacturing processes. Team attorneys have represented:

  • One of the world's leading centrifuge manufacturers, and an ethanol energy company in a multi-district litigation against 17 defendants. We led the joint-defense effort in successfully challenging the validity of the four asserted patents related to the recovery of oil from evaporated thin stillage. In granting our motions for summary judgment, the district court declared the patents invalid based on the on-sale bar, anticipation, obviousness, failure to name the correct inventors, inadequate written description and lack of enablement.
  • A leading multinational engineering company in connection with the assertion of patents covering automotive parts in various district courts against numerous defendants. Obtained jury verdict in District of Delaware finding patents valid and infringed. The Federal Circuit affirmed the validity and infringement findings and, in ordering the district court to enter an injunction sought by our client, issued a landmark ruling concerning the continued availability of injunctions after the Supreme Court’s eBay decision. Successfully handled more than a dozen subsequent cases over the next several years obtaining favorable settlements for our client.
  • A leading multinational engineering company in a proceeding before the ITC in the assertion of numerous patents concerning wiper blades against numerous foreign companies. Successfully handled claim construction hearing in which 37 claim terms were construed, which resulted in a favorable settlement shortly after the final hearing began.
  • An American endodontic-equipment manufacturer against allegations of infringement of patents related to endodontic files in the Western District of Pennsylvania and the ITC. Case settled after favorable manufacturing/supply agreement was entered. In a subsequent breach of contract action, jury awarded client $44 million in damages.
  • A leading engineered-materials company against allegations of infringement of a patent on a measurement system for a type of plywood. Obtained summary judgment of non-infringement.
