The verdict
OTIS holds 1,319 US patents across 146 technology areas, rank #325 of 50,000 tracked assignees.
OTIS Elevator Company has been granted 1,319 US utility patents between 2015 and 2025, placing OTIS Elevator Company at rank #325 across all assignees tracked by PlainPatent. This portfolio spans 146 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.2 claims per patent with primary concentration in B66B (ELEVATORS; ESCALATORS OR MOVING WALKWAYS). As a US Corporation, OTIS Elevator Company is one of the broader-portfolio assignees in the PatentsView dataset. By volume, OTIS sits between Harman International Industries, Incorporated (1,341 patents, rank #321) and Yamaha Hatsudoki Kabushiki Kaisha (1,310 patents, rank #329) - the closest US assignees by grant volume. The composite Innovation Score of 64.4/100 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 833 grants, compared with 486 in the 2015–2019 window, a +71% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. OTIS Elevator Company's 15.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark OTIS Elevator Company against peers pursuing similar technology classes.

How to use this portfolio
OTIS's 1,319 grants land it in the top 2% 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.
