To apply for a patent for invention or utility model, a written request, a specification, an abstract thereof, a patent claim and other documents shall be submitted.
The request shall specify the name of the invention or utility model, the name of the inventor, the name and address of the applicant and other matters.
The specification shall give a clear and complete description of the invention or utility model, which shall be subject to the realization of the technical personnel in the technical field; Attached drawings shall be attached when necessary. The technical points of the invention or utility model shall be briefly explained.
It can be seen that the invention patent and utility model patent should be applied separately, but the application materials are similar.
As far as the procedure is concerned, the application procedure is the same, but the approval procedure is different. The utility model procedure is relatively simple and short, which is suitable as a transitional protection means for invention patents. After the invention patent is obtained, the invention patent is generally the main protection means.
As far as the problem is concerned, the application for invention and utility model should be separated from payment according to law.
