Does the intellectual property agency have the obligation to inform the patentee of the obligation to pay the annual fee?

After the patent application is authorized, it will face the problem of paying the annual fee on time every year. Whether a patent agency has the obligation to notify the patentee to pay the annual fee depends on the specific circumstances entrusted by the patent agency. If only the format power of attorney for patent agency on the website of China National Intellectual Property Administration is adopted, from the legal point of view, the patent agency is obliged to forward the letter sent by the China National Intellectual Property Administration Patent Office to the patentee in time, including the notice of paying the annual fee, but there is no legal provision on whether to inform the patentee in detail.

If you not only use the power of attorney in the format specified by the patent office, but also sign the corresponding agreement with the patent agency, the annual fee and other issues can be implemented in accordance with the terms of the contract (you can stipulate the payment by the patent agency, or how long the patent agency will inform you in advance, etc.). ).
