USA - Cummins Inc of Columbus, Indiana, has completed successful legal actions against Turbo Lab LLC of Stuart, Virginia, for infringement of Cummins’ patents by the unauthorised marketing and selling of turbo nozzle rings, a critical component of the Holset VGT turbo. Turbo Lab agreed Cummins’ patents were valid and infringed and, as part of the settlement, it further agreed to cease and desist purchasing, making and selling any nozzle ring product that infringes Cummins’ patents, and to destroy all existing infringing stock.

Cummins said, “Innovation and generation of intellectual property have been a part of the Holset VGT success since Cummins Turbo Technologies first pioneered the variable geometry technology for the commercial vehicle market in 1998. Cummins Turbo Technologies continues to invest in the development and protection of new technologies that advance its VGT turbos to provide customers dependable and reliable products that improve fuel economy and play a critical role in meeting more stringent emission regulations.”
