Independent claims are the core part of patent claims. They can independently define the scope of protection of the patent without relying on the limitations of other claims. Generally speaking, the more independent claims, the more inventions the patent has and the wider the scope of protection. Therefore, it is considered to be one of the important indicators of patent quality. This factor calculates the average number of independent claims of newly authorized patents in the past five years, reflecting the overall innovation ability and patent quality level of the company in the past period of time. A higher average number of independent claims in the past five years may indicate that the company has higher-value intellectual property rights and stronger technological competitiveness.
