What's the fastest time to apply for an appearance patent?

About six months. It takes about 6 months at the earliest to apply for a patent for appearance, mainly because the patent application process involves many stages and links. After the design drawings are submitted, they need to be formally reviewed and accepted, which takes about 5 working days. It takes about 4 to 6 months to enter the preliminary examination stage. At this stage, the Patent Office will examine whether the application documents for the design patent meet the authorization standards, including whether the application meets the legal requirements and whether it conflicts with the existing design. The certification phase takes about 2 to 3 months. At this stage, the Patent Office will complete all necessary administrative procedures, such as paying the patent registration fee and stamp duty, and then issue the patent certificate.
