Extended data:
Disclosure is a procedure for examining an application for a patent for invention. Its purpose is to let the public know that someone wants to apply for a published invention. From disclosure to authorization, anyone can submit materials to the Patent Office that can prove that the published patent application is not novel or creative. The purpose of this should be to use the power of the public to examine patent applications.
After the patent application is published for a period of time, the Patent Office will conduct a formal review of the patent application, such as whether the patent claim is clear, whether the specification is fully disclosed, whether the invention has three characteristics, and whether there is oneness between multiple inventions in the same application. After the application meets the above requirements, it can be authorized.
The date of patent application is of great legal significance: it determines the time of filing the application, and when there are multiple applications with the same content, the order of application determines who will be granted the patent right; It is the date standard to judge whether an invention is novel, because it determines the retrieval period of the existing technology.
This date is also the beginning date of a series of important periods in the examination procedure and the patent protection period after the patent application is authorized. The applicant's rights will also be "temporarily protected" from the application date to the authorization, and the application with the same theme after the application date will lose novelty because of its conflict, and the patent right cannot be granted.
The published patent application is in the temporary protection period. If there is "infringement" after the publication date, it can be handled in accordance with the patent law.
