A handle on the matter

A patent for a washing bowl for hospitals made of moulded paper pulp with recesses for lifting, has been declared valid by the Patents County Court. It found that two of three bowls produced by the defendant infringed the patent. While the defendant argued that the invention was common knowledge, this argument failed. The lips of a bowl might be strong enough for lifting and there would be no need for recesses so a skilled person could design a version that did not infringe the patent.
