USPTO PatentsView assignee record - 6 granted patents across 5 technology areas, active 2022–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: 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;).
The verdict
Shenzhen holds 6 US patents across 5 technology areas, rank #42,851 of 50,000 tracked assignees.
Shenzhen KIWI Instruments Corporation has been granted 6 US utility patents between 2022 and 2025, placing Shenzhen KIWI Instruments Corporation at rank #42,851 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.8 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 Foreign Corporation, Shenzhen KIWI Instruments Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Shenzhen sits between Shenzhen Jashen Technology Co., Ltd. (6 patents, rank #42,847) and Shenzhen Skyworth-rgb Electronics Co., Ltd. (6 patents, rank #42,855) - the closest US assignees by grant volume. The composite Innovation Score of 44.1/100 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 2022 through 2025, with 6 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. Shenzhen KIWI Instruments Corporation's 15.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shenzhen KIWI Instruments Corporation against peers pursuing similar technology classes.

How to use this portfolio
Shenzhen's 6 grants land it in the top 26% 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.
