Hadley Industries Plc v Metal Sections Limited, Metsec (UK) Limited: PatC 13 Nov 1998

A court no longer has the discretion as to whether to amend a patent upon application, but must, following European practice, do so when a proper application is made. This is the case despite the clear wording of the English Act. A judge at first instance should be careful to follow a line of cases also at first instance so as to avoid uncertainty: ‘I do not pretend that I would have regarded the point as at all easy, if it had been virgin territory. It would be wrong to leave this case with the impression that I regard the decisions of the three judges as clearly right or, indeed, as wrong. What I do think is that the arguments that I have been presented with do not justify me in departing from those decisions. I consider that the arguments that have been addressed to me are arguments which should be addressed to the Court of Appeal. For my part, I await their decision with interest. For me, I think the right course must be to follow Laddie J, Pumfrey J and Jacob J. Whether one characterises that course as craven or prudent no doubt depends on whether one is [the defendant] or the [claimant].’
