It takes at least two years to authorize an application for a patent for invention, or even five or six years without authorization. The main reason is that the notice of review opinions will be issued in the actual trial stage and a reply is needed. If the defects pointed out by the examiner cannot be corrected or can be persuaded, a notice of examination opinions will be issued again. In the end, either authorize or refuse. After rejection, you can submit a review request. If the request is passed, you can reply to the audit notice. If it fails, you can also bring a lawsuit to the court. Therefore, it is difficult to determine whether the application time for invention patents is long or short.
2. Do I need to find a third party to apply for an invention patent?
Of course. Of course, in addition to paying official fees, we also have to pay a certain amount of agency fees. In domestic cases, institutions are different. In foreign cases, there is a unified standard, but it is only relatively fixed. Entrusting a reliable agency is mainly to save worry and not make low-level mistakes, because after all, the agency has rich practical experience. Mainly depends on the applicant's own needs.
