Portfolio overview

Xiamen Hithium Energy Storage Technology Co., Ltd. has been granted 66 US utility patents between 2023 and 2025, placing Xiamen Hithium Energy Storage Technology Co., Ltd. at #5,257 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.7 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Xiamen Hithium Energy Storage Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Xiamen sits between Theranos IP Company, Llc (66 patents, rank #5,253) and AZ Electronic Materials (luxembourg) S.a.r.l. (65 patents, rank #5,261) - the closest US assignees by grant volume. The composite Innovation Score of 60.7/100 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 2023 through 2025, with 66 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. Xiamen Hithium Energy Storage Technology Co., Ltd.'s 16.7 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 21 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
