This statement is correct.
Patent agency means that a patent agency is entrusted by a party to entrust a patent agent with national patent agency qualifications to handle patent applications or other patent matters with the Patent Office in accordance with the provisions of the Patent Law within the scope of the entrustment. . Patent agencies can undertake patent consultation, patent applications, requests for substantive examination or reexamination, invalidation of patent rights, patent litigation and other related matters. Therefore, patent agency is a kind of principal agency.
Handling patent matters is a complex and detailed task. If the applicant is not familiar with patent legal regulations and related procedures, it is best to entrust a patent agency to represent the patent application. Because a patent application must first write qualified patent application documents, it is difficult for people without specialized training and practical experience in writing to complete it.
