What is a good patent claim?

The claim is the core part of the application document. A document in which the applicant applies for national protection of the invention-creation and delimits the scope of protection. Once approved, it has legal effect. Therefore, it is very important to write a book that benefits the applicant.

All new technical features described in the 1. manual shall be listed briefly, clearly and completely.

2. The technical terms and terms used in the claims shall be consistent with those in the specification.

3. A proposition should be expressed in one sentence, with commas and pauses in the middle, not semicolons and periods.

The claim only talks about the technical features of the invention or utility model, and it is not allowed to state the purpose and function of the invention or utility model.

5. Claims are divided into independent claims and dependent claims.

6. An invention or utility model should have only one independent claim.

The patent claim shall, on the basis of the specification, explain the technical features of the invention or utility model and limit the scope of protection of the patent application. After the patent right is granted, the patent claim is the basis for determining the scope of the patent right of the invention or utility model, and it is also the basis for judging whether others infringe, and it has direct legal effect. Claims are divided into independent claims and dependent claims.

An independent claim should reflect the main technical content of an invention or utility model as a whole, and it is a claim that records the necessary technical features that constitute an invention or utility model. Dependent claims refer to one or more claims, including all technical features of another (or several) claims, as well as further defined technical features. The writing of the claim must be very strict and accurate, and have a high degree of legal and technical skills.
