Article 42 of the Patent Law: The term of the invention patent right is 20 years, and the term of the utility model patent right and the design patent right is 10 years, both counting from the date of filing.
After receiving the acceptance notice, the date of patent application has been determined, which is a very important time. After this time, you can disclose your product in any form, which will not affect the authorization of this patent.
It should be appropriate to develop products now, and the general examination time for utility model patents is 6 to 7 months. It should also be noted that the patent protection period is calculated from the date of authorization announcement.
After the product is made public and before the patent is granted, the only thing you can do is to warn the other party that you have applied for a patent. Once the patent is granted, you can use legal weapons to protect your interests.
