Portfolio overview

Contemporary Amperex Technology Co., Limited has been granted 1,029 US utility patents between 2016 and 2025, placing Contemporary Amperex Technology Co., Limited at rank #440 across all assignees tracked by PlainPatent. This portfolio spans 118 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.4 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, Contemporary Amperex Technology Co., Limited is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Contemporary sits between Mitsubishi Chemical Corporation (1,040 patents, rank #436) and DEKA Products Limited Parternship (1,025 patents, rank #444) - the closest US assignees by grant volume. The composite Innovation Score of 71.3/100 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. Between 2020 and 2025 the company received 983 grants, compared with 46 in the 2015–2019 window, a +2037% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Contemporary Amperex Technology Co., Limited's 14.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Contemporary Amperex Technology Co., Limited against peers pursuing similar technology classes.
