Obvious Patent Queried - Disclosure Allowed
Nichia Corpn v Argos Ltd [2007] EWCA Civ 741
CA
Weekly Law Reports Summary
19 July 2007
Where the validity of a patent was challenged on the ground of obviousness, and there was no issue of commercial success or long-felt want, disclosure of evidence from the patentee was of limited scope and usefulness. There was, however, no blanket rule that disclosure should not be ordered in such circumstances.
