A patent infringement verdict for US$2.7m against Brunswick Corp was upheld by a US Federal Circuit court last week. The decision by the US court affirmed an earlier Patent Trial and Appeal Board (PTAB) decision that said that Brunswick had infringed a patent held by Cobalt Boats for a dual-level boat step, according to Law360.com. The case originally began in a Virginia federal court, where a jury awarded Cobalt US$2.7m against Brunswick for the infringement. The jury found that Brunswick had infringed one of two patent claims and concluded that the infringement was willful. That automatically tripled the damages.
