What is patent inquiry?

Patent inquiry is a procedure before patent application. Not necessary, but necessary. An effective search report can make the applicant avoid that the right to be protected is not the same or similar to the patent right of the previous application, and ensure that the applied patent is valid.

An application for a patent shall be submitted by the applicant to the State Patent Office, which shall approve it and issue a certificate. When filing a patent application with the State Patent Office, the applicant shall also submit a series of application documents, such as the request, specification, abstract and patent claim. In terms of patent application, the provisions of the patent laws of all countries in the world are relatively consistent, but there are also many differences.

Extended data

The purpose of patent search is to compare whether it is similar or not. You can operate through the patent search channel in China National Intellectual Property Administration. In order to query the comparison results more accurately and professionally, you can find a professional organization to handle it for you.

Patent application and layout often involve several countries. Therefore, it is not only a waste of time to search separately in different free patent databases, but also an error will occur because different databases use different languages and grammars (each country's databases use different grammars). Therefore, it is particularly important to choose a comprehensive source file library with more data.
