How to inquire patent ipc classification number

After the patent application documents are submitted to the patent office, the patent office will process the application documents, one of which is IPC classification.

In IPC classification, information such as technical subject, function and application is extracted according to the contents of patent application documents, and then the corresponding classification number is found. A patent application document may involve many technical topics, functions, applications, etc. And it needs to be classified many times. Therefore, a patent application document often has multiple classification numbers.

For specific technical topics, you can check the corresponding IPC classification on official websites such as China National Intellectual Property Administration and WIPO. In addition, the usual patent data retrieval website will be accompanied by an IPC classification number query tool.

If you want to know the patent ipc classification number in detail, I suggest you go to the enterprise knowledge inquiry policy platform for inquiry.
