What should I pay attention to after a successful patent application?

As we all know, there are three kinds of patent applications, namely, invention patents, utility model patents and design patents. It takes a lot of materials to apply for a patent, and we need to do a lot of work before applying for a patent. After the patent application is successful, everyone must not relax, and there are still many matters needing attention after the patent application. Next, I will explain the intellectual property rights of Bajie to you one by one: 1. It is necessary to keep all patent application materials and receipts; If the address and name change after the application, it shall go through the formalities of change with the Patent Office in a timely manner, and fill in the statement on the change of the project description; Payment, from the beginning of the application to the termination of the patent right, must go through multiple payment procedures. Anyone who applies for a patent for invention may, within 3 years from the date of application, submit a request for substantive examination to the Patent Office in duplicate and pay the examination fee. 2. The application documents can be directly submitted or mailed to the Chinese Patent Office or Shanghai Branch and the representative offices in Shenyang, Jinan, Changsha, Nanjing and Chengdu. E-mail must be registered and receipts must be kept. E-mail should indicate the patent application or be written in China Patent Office for examination. 3. Determination of application date. The date of application is very important to the applicant. It determines the sequence of application time and the scope of existing technology in the examination procedure, and it is also the starting point of a series of related deadlines in the future, such as calculating the date of filing the substantive examination request and the date of patent right. Note: If the specification submitted contains the description of the drawings, but the drawings are not actually submitted, the Patent Office will notify the applicant to submit the drawings within the specified time limit, and the submission date is the new application date, and the original application date is invalid. If the appended drawings are cancelled by means of correction, the original application date shall be maintained. In addition, the original application for the invention patent will be changed to utility model, and the original application date will be revoked, and the later submission date will be the new application date.
