The verdict
Channel holds 9 US patents across 8 technology areas, rank #28,353 of 50,000 tracked assignees.
Channel WELL Technology Co., Ltd. has been granted 9 US utility patents between 2018 and 2025, placing Channel WELL Technology Co., Ltd. at rank #28,353 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.1 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 Foreign Corporation, Channel WELL Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Channel sits between Chang GUNG Biotechnology Corp. (9 patents, rank #28,349) and Chaun-choung Technology Corp. (9 patents, rank #28,357) - the closest US assignees by grant volume. The composite Innovation Score of 44.6/100 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 8 grants, compared with 1 in the 2015–2019 window, a +700% 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. Channel WELL Technology Co., Ltd.'s 11.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Channel WELL Technology Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Channel's 9 grants land it in the top 25% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
