IPO Withers and Rogers, a firm of patent attorneys, applied for the revocation of Mr Dobson’s patent on behalf of an anonymous client. The grounds were that the invention was not patentable because it lacked an inventive step having regard to certain prior art, notably patent number US5347765 and an alleged marketing brochure from a company called Joran Bor A/S. The invention relates to an elongate mortar raking tool coated with diamond grit for use with an angle grinder.
The claimant failed to provide sufficient evidence to prove the publication date of the non-patent citation, though the obviousness of the invention in the event that the citation’s date had been proven was considered.
The hearing officer found the patent to be inventive over the cited prior art and dismissed the application for revocation.
