The Board vacated reversed a decision that deletion of drawings amounted to an extension of protection. The opposition Opposition division Division had revoked the patent with the argument that the amendment generally had an impact on the extent of protection conferred by the European patent because the drawings would be used to resolve ambiguities in the claims. The Board reversed because the impugned decision failed to identify any such ambiguity.
