How to apply for a patent for ceramic tile formula

Under normal circumstances, a patent application is submitted to China National Intellectual Property Administration after the patent application documents are written, and a certificate is authorized to be issued after examination and approval. Among them, the examination of invention patent application includes the preliminary examination stage and the actual examination stage, so the examination time is long and the authorization is difficult, but the "gold content" is also high. The utility model patent and the design patent do not need substantive examination, so the examination time is relatively short and the authorization is relatively easy. For example, ceramic tile formulas usually apply for invention patents. However, writing application documents requires skill, and patent search is needed before application to ensure the quality of writing patent application documents. Therefore, if you don't understand these operations, you'd better find a formal agency, and they have professionals to handle related matters for you.
