Jiangsu Contemporary Amperex Technology Limited has been granted 63 US utility patents between 2021 and 2025, placing Jiangsu Contemporary Amperex Technology Limited at #5,450 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.8 claims per patent with primary concentration in H01M (PROCESSES OR MEANS, e.g. BATTERIES, FOR THE DIRECT CONVERSION OF CHEMICAL ENERGY INTO ELECTRICAL ENERGY). As a Foreign Corporation, Jiangsu Contemporary Amperex Technology Limited is one of the more focused assignees in the PatentsView dataset. By volume, Jiangsu sits between Innoscience (zhuhai) Technology Co., Ltd. (63 patents, rank #5,446) and Nationwide Mutual Insurance Company (63 patents, rank #5,454) - the closest US assignees by grant volume. The composite Innovation Score of 59.2/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Grant cadence records the difference between two grant-year windows. Historical data spans 2021 through 2025, with 63 total grants over that period. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.
Claim depth and technology breadth describe this aggregate record. Jiangsu Contemporary Amperex Technology Limited's 13.8 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 22 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
