Securing non-infringement declarations

There was no dispute between the parties that the procedural requirements of Section 69(1) of the act were complied with. In terms of that section the patentee had failed to give an acknowledgement of non-infringement. The dispute was whether the Videx product, a preload device or pot used in mining, infringed the Camworth patent by falling within the ambit of any of the claims of the patent.
