The Case

Patent Validity. The Chancery Division, Patents Court, decided, inter alia, that of the two patents, owned by the defendant company relating to treatments for protecting pets or small mammals from pleas, which the claimant company sought to revoke, patent 881 was not invalid either on the basis of obviousness or insufficiency. However, patent 564 was invalid on the ground of insufficiency alone.
