Does the patent agency know the formula?

The detailed rules for the implementation of the patent law are clear, and the instructions should be fully disclosed, subject to the implementation of ordinary technicians in this field. Of course, sometimes the applicant wants to have some reservations because it involves technical secrets, but it is best to do so without affecting the authorization, because the examiner will reject your application because you have not fully disclosed it, or the patent may be invalid because you have not fully disclosed it in the subsequent patent infringement litigation. So I suggest you still think about it and consult a professional organization.
