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.  We served as lead counsel for a joint defense group in a multi-district litigation brought by our client against 30 defendants. After successfully challenging the validity of the four patents asserted against the defendants and obtaining a finding of inequitable conduct following a bench trial, we led the effort that resulted in a ruling from the court that the case was “exceptional” under 35 U.S.C. § 285 and that defendants were entitled to attorney’s fees and costs. In addition, we served as lead counsel on plaintiff’s appeal of the court’s prior decisions on validity and inequitable conduct to the Federal Circuit. The Federal Circuit ruled in favor of the joint defense group, affirming the district court’s determination that the patents-in-suit are unenforceable due to inequitable conduct.
  • 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.
  • 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.
