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 #11,207 of 50,000 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. By volume, Chaoyang sits between CDE Global Limited (27 patents, rank #11,199) and Coperion Gmbh (27 patents, rank #11,207) - the closest US assignees by grant volume. The composite Innovation Score of 35.5/100 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. Between 2020 and 2024 the company received 15 grants, compared with 11 in the 2015–2019 window, a +36% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. 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 US Corporation classification provides context for the assignee record, not a conclusion about its business strategy.
Claim depth and technology breadth describe this aggregate record. Chaoyang Semiconductor Jiangyin Technology Co., Ltd.'s 11.8 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.

How to use this portfolio
Chaoyang's 27 grants land it in the top 49% 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 - Chaoyang ranks #11,207 of 50,000. Top 50 holders
- Most of this portfolio concentrates in H02M - see who else leads that technology area. H02M 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.
