Cantel v Arc Medical: Secondary Evidence for Obviousness
In Cantel v Arc Medical Design, anticipating the end of its distribution agreement, Cantel sought a declaration of non-infringement and/or revocation of certain of Arc Medical Design’s patents and design. The patents and designs related to a device used with a colonoscope to improve visibility of the wall of the colon during colonoscopy.
The Patents Court of England & Wales held that the rights were valid and that certain rights were either infringed or would be infringed. In doing so, HHJ Hacon, sitting as a High Court Judge, provides a useful guide on the use of secondary evidence to assess obviousness.
