Ashton Chantrielle recently appeared for the patentee in a patent revocation action at the Intellectual Property Office.
The patent related to a system for cooling and dispensing beverage in which the beverage was cooled en route to the dispensing font. The font was also cooled to create a decorative ice effect. The claimant applied to invalidate the patent on the basis on four main grounds of revocation. The patent was held to be valid.
