Portfolio overview

Hithium TECH HK Limited has been granted 11 US utility patents between 2025 and 2025, placing Hithium TECH HK Limited at rank #24,446 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.4 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, Hithium TECH HK Limited is one of the more focused assignees in the PatentsView dataset. By volume, Hithium sits between Highspot, Inc. (11 patents, rank #24,442) and Houghton Technical Corp. (11 patents, rank #24,450) - the closest US assignees by grant volume. The composite Innovation Score of 24.9/100 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 2025 through 2025, with 11 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. Hithium TECH HK Limited's 15.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hithium TECH HK Limited against peers pursuing similar technology classes.
