If you mean products, you can apply for a patent. The steps of applying for a patent are as follows: 1) Write patent application materials, including patent request, abstract of specification, appended drawings of abstract, patent claim, specification, appended drawings of specification, etc. All the above documents are indispensable, and the writing requirements of the documents are very strict. Most people can't do it independently, so they need to find an agency or a professional to help.
2) Send the patent application materials to the acceptance office of China National Intellectual Property Administration Patent Office, and wait for the notification of acceptance by the Patent Office.
3) Pay the patent application fee, the examination fee for the invention patent and wait for the patent authorization notice after receiving the notification from the Patent Office.
4) Pay the certificate fee and the annual fee for the first year in time after receiving the patent authorization notice, and wait for the patent certificate to be issued.
Obtaining a patent certificate means that the patent application is successful.
Supplement: Only drawings and technical solutions with product concepts can apply for patents. You can't just apply for a patent for functional ideas.
You can't apply for a patent in the planned direction.
Whether it is thinking about products or planning direction, you must have a technical plan before you can apply for a patent.
