Meaning
Administrative review boards operating within national intellectual property offices evaluate appealed patent rejections and invalidation petitions. Under Chinese patent law, the CNIPA re-examination department functions as the specialized administrative body under the National Intellectual Property Administration responsible for handling appeals against rejected patent applications and petitions to declare existing patents invalid. Statutory authority rests under Article 41 and Article 45 of the Patent Law of the People’s Republic of China, providing an administrative remedy before dispute resolution enters the court system.
Foreign patent holders must engage licensed Chinese patent agencies to represent them in proceedings before this body.
Administrative Scope
Statutory power enables the panel to affirm examiner rejections or declare granted claims invalid. Panel decisions modify patent scope directly without requiring judicial confirmation. Enforceable rights exist immediately upon publication of an invalidation decision, terminating the patent holder’s ability to claim infringement damages for invalidated claims in court.
Procedural Sequence
Written petitions trigger a formal examination phase where evidence is submitted under strict time limits. Parties submit formal observations and counter-arguments within designated response windows, typically ranging from one to three months. Panel members conduct technical reviews and may convene oral hearings to resolve conflicting technical evidence or claim construction disputes.
Formal decisions are rendered in writing, outlining legal grounds and evidentiary findings.
Judicial Appeal
Administrative rulings issued by the department do not constitute final unappealable judgments. Unsatisfied parties retain the right to file an administrative lawsuit with the Beijing Intellectual Property Court within three months of receiving notice. Courts review administrative legality rather than re-examining patent applications from scratch.
Failure to file a court challenge within the statutory timeframe renders the administrative decision final and binding.
