Portfolio overview

CHAOYANG SEMICONDUCTOR JIANGYIN TECHNOLOGY CO., LTD. has been granted 27 US utility patents between 2018 and 2025, placing CHAOYANG SEMICONDUCTOR JIANGYIN TECHNOLOGY CO., LTD. at rank #11,203 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.8 claims per patent with primary concentration in H02M (APPARATUS FOR CONVERSION BETWEEN AC AND AC, BETWEEN AC AND DC, OR BETWEEN DC AND DC, AND FOR USE WITH MAINS OR SIMILAR POWER SUPPLY SYSTEMS; CONVERSION OF DC OR AC INPUT POWER INTO SURGE OUTPUT POWER;). As a US Corporation, CHAOYANG SEMICONDUCTOR JIANGYIN TECHNOLOGY CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 35.5/100 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 16 grants, compared with 11 in the 2015–2019 window, a +45% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The US 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. CHAOYANG SEMICONDUCTOR JIANGYIN TECHNOLOGY CO., LTD.'s 11.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, 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 CHAOYANG SEMICONDUCTOR JIANGYIN TECHNOLOGY CO., LTD. against peers pursuing similar technology classes.
