1, independent application: first, make clear what kind of patent, invention, utility or appearance you want to apply for. Prepare application materials, requests for patents for inventions or utility models, claims, specifications, drawings of specifications, abstracts of specifications, drawings of abstracts, requests for fee reduction and other documents; Design patent request, design photos or pictures, brief description, fee waiver request and other documents. Submit an application to the Intellectual Property Office and pay the application fee. The Intellectual Property Office will conduct a review, and if it fails, it will be rejected. Then you can complain and modify. Then review it again. There will be a novelty retrieval process for invention patents, which is more expensive.
2, find a patent agency: this is relatively easy to handle, how to apply, what materials to take, how to write, should be helpful to the operation.
Time required:
Invention patents generally take about two years, and applications for utility models and designs can take half a year.
