It is recommended to find a patent attorney or patent engineer when drafting a patent. To avoid correction later.
1. The claims should be based on the description and clearly and briefly define the scope of patent protection required.
2. The claims should record the technical features of the invention or utility model.
3. If there are several claims in the claim, they should be numbered sequentially with Arabic numerals.
4. The scientific and technical terms used in the claims should be consistent with those used in the description. They can have chemical formulas or mathematical formulas, but there must be no illustrations.
5. The technical features in the claims can refer to the corresponding signs in the drawings of the specification. The signs should be placed after the corresponding technical features and placed in parentheses to facilitate understanding of the claims. Reference signs shall not be construed as limitations on the claims.
