USPTO PatentsView assignee record - 9 granted patents across 8 technology areas, active 2021–2024. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B65G (TRANSPORT OR STORAGE DEVICES, e.g. CONVEYORS FOR LOADING OR TIPPING, SHOP CONVEYOR SYSTEMS OR PNEUMATIC TUBE CONVEYORS).
The verdict
Korea holds 9 US patents across 8 technology areas, rank #29,186 of 50,000 tracked assignees.
Korea Wheel Corporation has been granted 9 US utility patents between 2021 and 2024, placing Korea Wheel Corporation at rank #29,186 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.3 claims per patent with primary concentration in B65G (TRANSPORT OR STORAGE DEVICES, e.g. CONVEYORS FOR LOADING OR TIPPING, SHOP CONVEYOR SYSTEMS OR PNEUMATIC TUBE CONVEYORS). As a Foreign Corporation, Korea Wheel Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Korea sits between KOEI Chemical Company, Limited (9 patents, rank #29,182) and KPS Global Llc (9 patents, rank #29,190) - the closest US assignees by grant volume. The composite Innovation Score of 46.0/100 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 2021 through 2024, with 9 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. Korea Wheel Corporation's 13.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Korea Wheel Corporation against peers pursuing similar technology classes.

How to use this portfolio
Korea's 9 grants land it in the top 22% 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.
