Patent review for UK fire door manufacturer

I was asked to help decide if the design of fire doors manufactured by one manufacturer infringed another door manufacturer’s patent. I was given a copy of the patent in question, access to fire test reports, door design drawings and abstracts of international patents to examine. My interpretation of the drawings was made, and papers I had written were used as background information together with the results of a search of historical fire documents in the British Library. The outcome is unknown.

Client: A London firm of solicitors.
