Hakim v. Cannon Avent Group: What's the Spillover?

By Matthew Siegal and Natalie McClurg
November 29, 2007

Your client Su Co., a manufacturer of non-spill sippie cups, calls you with a problem regarding a patent application for which you recently secured allowance on its behalf. The Patent and Trademark Office had approved the application after you amended the original claims to describe that two specific parts are joined together and argued that some very close prior art lacked that feature. With that patent in hand, your client had eagerly looked forward to shutting down various competitors who were, in your client's view, infringing its rights.

Su Co. now informs you that the allowed claims would not literally cover a competitor's knock-off cup that associates the parts, but does not physically join them together. 'Not to worry,' you tell Su Co, 'we can file a continuation application with slightly broader claims that avoid the prior art while still covering the competitor's product.'

Not wanting it to look like you are trying to pull a fast one, you point out to the examiner where you have broadened the claims and succinctly state that the claims remain patentable for the same reasons as argued in the prior amendment in the prior application. You also request that the examiner review each reference to confirm that the amended claims are still patentable. Have you done all that is necessary to broaden your claims? After the Federal Circuit's decision in Hakim v. Cannon Avent Group, PLC, 479 F.3d 1313 (Fed. Cir. 2007), the answer is 'Not necessarily.'
