Can I apply for a patent if I disclose the technology on my own product?

The "existing technology" to judge the novelty and creativity of a patent is defined as the technology that was published in domestic and foreign publications before the filing date, publicly used in China or known to the public in other ways. No matter who makes it public, it belongs to the prior art as long as it is in a state that the public can obtain it normally.

But there is one exception, that is, the grace period of novelty.

Article 24 An invention-creation applying for a patent shall not lose its novelty in any of the following circumstances within six months before the date of filing:

(1) It was exhibited for the first time at an international exhibition sponsored or recognized by the China Municipal Government;

(2) It was first published at a specific academic conference or technical conference;

(3) Others disclose the contents of the application without the consent of the applicant.

However, if you disclose your own technology before the application date, it can be understood as a voluntary contribution to the corresponding technology.
