After obtaining the patent agent qualification, you need to intern in a patent agency or related position for one year before a practicing certificate can be issued. In other words, if no relevant internship is done within five years, the patent agent qualification will be cancelled.
If you have been engaged in relevant work within five years, there are two situations: 1. After one year of internship and a practicing certificate issued, you must undergo an annual review every year, otherwise you will be dismissed within the agency association. deal with. 2. If the internship is less than one year and no longer engaged in relevant work, the qualification will be revoked five years after leaving the affiliated unit (agency or patent administration position).
The above two situations are relatively rare. Generally, you will have to intern for one year and obtain a practicing certificate. Even if you no longer engage in relevant work, you will be affiliated with an agency.
The patent agent mentioned in your second question should refer to an agent who has obtained a patent agent practice certificate, that is, a formal licensee. Interns who have obtained patent agent qualifications are bound by the relevant confidentiality agreement of the unit. The former is not allowed to apply for a patent in his or her own name, while the latter's patent application is illegal. Therefore, any application made by the two is invalid.
