High Court, following determination that a patent was invalid: (a) grants a stay on the order revoking the patent and removing it from the register, pending an appeal to the Court of Appeal; but (b) refuses to grant an order continuing an injunction restraining the defendant from infringing the patent by marketing a generic version of the product, on the grounds that the patent had been found invalid at first instance, and the balance of justice favoured the defendant being permitted to 'reap the commercial reward' for successfully challenging the patent.
