I forgot to sign the waiver of patent application, resulting in no waiver. What should I do?

Method 1: resubmit the qualified fee waiver request. Disadvantages: the application fee cannot be reduced, but the follow-up fee can be reduced.

Method 2: resubmit the patent application documents and qualified fee reduction requests. Disadvantages: The original application is regarded as withdrawn, and the new application date may affect novelty and creativity.

Method 3: Re-submit the patent application documents and the qualified Request for Fee Reduction, and claim the priority of the original application. Disadvantages: 80 yuan's priority claim fee is spent more.
