Why do patents fail?

The main reasons for patent invalidation are: (1) The patent application documents do not meet the requirements of preliminary examination. After accepting an application for a patent, China National Intellectual Property Administration shall make a preliminary examination on whether the application procedures are complete, whether the documents are complete, whether the instructions conform to the provisions of the patent law, whether the identity of the applicant conforms to the requirements of the patent law, whether the invention theme belongs to the protection scope of the patent law, and whether the application fee is paid. If the above matters do not meet the requirements, the applicant shall be required to make corrections within a specified time limit. If the applicant fails to make corrections within the time limit, his application shall be deemed to have been withdrawn. If it still does not meet the requirements of the patent law after correction, it shall be rejected. Whether it is deemed to be withdrawn or rejected, the applied patent is invalid. (2) The patent applicant withdraws it after the publication of the application. After preliminary examination, China National Intellectual Property Administration believed that the application for a patent for invention was in conformity with the provisions of the Patent Law, and immediately announced the applicant's invention. The applicant shall request substantive examination within the statutory time limit. Where the applicant fails to request substantive examination, the application shall be deemed to have been withdrawn and become an invalid patent. (3) The patent applicant fails to reply within the time limit without justifiable reasons. If China National Intellectual Property Administration considers that the invention patent does not conform to the provisions of the Patent Law after substantive examination, it shall notify the applicant and ask him to state his opinions or amend his application within a specified time limit. If the applicant fails to reply within the time limit without justifiable reasons, it shall be deemed to have been withdrawn and become an invalid patent. (four) did not apply for patent protection in China. Patent right is regional, and the patent right granted by a country can only be supported and protected within the jurisdiction of that country's laws. If a foreign patent fails to apply for patent protection in China within one year, it will not be protected by the Patent Law of China, and the patent will become invalid in China. Article 45 of the Patent Law: Since the date when the patent administration department of the State Council announced the grant of the patent right, any unit or individual may request the Patent Reexamination Board to declare the patent right invalid if it considers that the grant of the patent right is not in conformity with the relevant provisions of this Law. Article 46 The Patent Reexamination Board shall promptly examine the request for invalidation of the patent right and make a decision, and notify the requester and the patentee. The decision to declare the patent right invalid shall be registered and announced by the patent administration department of the State Council. Anyone who refuses to accept the decision of the Patent Reexamination Board to declare the patent right invalid or maintain the patent right may bring a lawsuit to the people's court within three months from the date of receiving the notice. The people's court shall notify the other party to the procedure for requesting invalidation to participate in the proceedings as a third party. Article 47 An invalid patent right shall be regarded as nonexistent from the beginning. The decision to declare the patent right invalid has no retrospective effect on the patent infringement judgments and conciliation statements made and executed by the people's court before the patent right was declared invalid, the decisions on handling patent infringement disputes that have been performed or executed, and the patent licensing contracts and patent transfer contracts that have been performed. However, if the patentee's malice causes losses to others, it shall make compensation. If the patent infringement compensation, patent exploitation fee and patent transfer fee are not returned in accordance with the provisions of the preceding paragraph, which obviously violates the principle of fairness, they shall be returned in whole or in part.
