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 rank #5,257 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. The composite Innovation Score of 60.7/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Historical data spans 2023 through 2025, with 66 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. XIAMEN HITHIUM ENERGY STORAGE TECHNOLOGY CO., LTD.'s 16.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 21 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark XIAMEN HITHIUM ENERGY STORAGE TECHNOLOGY CO., LTD. against peers pursuing similar technology classes.

How to use this portfolio

Xiamen's 66 grants land it in the top 3% by Innovation Score — but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance — Xiamen ranks #5,257 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in Y02E — see who else leads that technology area. Y02E leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

Patent counts and the Innovation Score measure patenting activity — not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
