2. If the fee waiver application submitted at the time of application is approved, then you should pay the actual audit fee according to the reduced fee, which is only needed after the actual audit is put forward.
3, about the actual trial, can be put forward at any time within 3 years from the date of application.
The process of invention patent is as follows: 1, apply; 2. Accept the application and give the patent application number; 3. Pay the application fee and the publishing and printing fee; 4. Qualified in the first instance; 5, put forward the actual trial, pay the actual trial fee; 6. When starting the substantive examination procedure, it may be necessary to reply to the examination opinions; 7. Enter the authorization procedure after the actual trial; 8. Pay the fees related to authorization; 9. Issue certificates
Of course, in most cases, when the application is submitted in step 1, both the application for fee reduction and the application for substantive examination will be submitted at the same time, and the related application fee and the actual examination fee will also be paid together when the approval fee is deferred, so that it is actually unnecessary to submit the actual examination and pay the actual examination fee after issuing the notice of qualified preliminary examination ~ ~
I think you invented your own situation, but you applied through the school, which means that the school is the real patent applicant, so it is not up to you to decide how much to pay, when to pay it and when to conduct the actual trial. I'm curious, did you pay the original application fee yourself? How much did you pay? If it's convenient, post the patent application number and help you check the relevant information.
