The patentee requested a review of Opinion 4/13 on the grounds that the examiner had misconstrued the claims and wrongly concluded that there was no infringement. The patent relates to fire fighting units and the invention is concerned with an arrangement of hose reel, pump and nozzle placed in a cabinet having a hinged door. The Hearing Officer found that the examiner had not misconstrued the meaning of the claims or misunderstood the relevance of the evidence, and had not reached a conclusion that was clearly wrong. The examiner had not considered the question of indirect infringement because he was not asked to do so. The Opinion was not set aside.
