Across all tracked assignees
USPTO PatentsView assignee record - 20 granted patents across 4 technology areas, active 2023–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H02B (BOARDS, SUBSTATIONS OR SWITCHING ARRANGEMENTS FOR THE SUPPLY OR DISTRIBUTION OF ELECTRIC POWER).
The verdict
JST holds 20 US patents across 4 technology areas, rank #14,706 of 50,000 tracked assignees.
JST Power Equipment, Inc. has been granted 20 US utility patents between 2023 and 2025, placing JST Power Equipment, Inc. at rank #14,706 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 23.6 claims per patent with primary concentration in H02B (BOARDS, SUBSTATIONS OR SWITCHING ARRANGEMENTS FOR THE SUPPLY OR DISTRIBUTION OF ELECTRIC POWER). As a US Corporation, JST Power Equipment, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, JST sits between Jawaharlal Nehru Centre FOR Advanced Scientific Research (20 patents, rank #14,702) and Just Fur Love Llc (20 patents, rank #14,710) - the closest US assignees by grant volume. The composite Innovation Score of 51.8/100 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 2023 through 2025, with 20 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. JST Power Equipment, Inc.'s 23.6 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark JST Power Equipment, Inc. against peers pursuing similar technology classes.

How to use this portfolio
JST's 20 grants land it in the top 11% 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.
