Portfolio overview

Kone Corporation has been granted 677 US utility patents between 2015 and 2025, placing Kone Corporation at rank #662 across all assignees tracked by PlainPatent. This portfolio spans 99 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.7 claims per patent with primary concentration in B66B (ELEVATORS; ESCALATORS OR MOVING WALKWAYS). As a Foreign Corporation, Kone Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Kone sits between Bayer Healthcare Llc (681 patents, rank #658) and National Taiwan University (671 patents, rank #666) - the closest US assignees by grant volume. The composite Innovation Score of 63.3/100 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 343 grants, compared with 334 in the 2015–2019 window, a +3% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Kone Corporation's 15.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 99 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kone Corporation against peers pursuing similar technology classes.

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.
