The verdict
KLA holds 503 US patents across 64 technology areas, rank #892 of 50,000 tracked assignees.
KLA Corporation has been granted 503 US utility patents between 2020 and 2025, placing KLA Corporation at rank #892 across all assignees tracked by PlainPatent. This portfolio spans 64 distinct Cooperative Patent Classification (CPC) subclasses, averaging 23.8 claims per patent with primary concentration in G03F (PHOTOMECHANICAL PRODUCTION OF TEXTURED OR PATTERNED SURFACES, e.g. FOR PRINTING, FOR PROCESSING OF SEMICONDUCTOR DEVICES; MATERIALS THEREFOR; ORIGINALS THEREFOR; APPARATUS SPECIALLY ADAPTED THEREFOR;). As a US Corporation, KLA Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, KLA sits between Nicoventures Trading Limited (511 patents, rank #888) and Airbus Helicopters (501 patents, rank #896) - the closest US assignees by grant volume. The composite Innovation Score of 80.7/100 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 2020 through 2025, with 503 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. KLA Corporation's 23.8 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 64 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark KLA Corporation against peers pursuing similar technology classes.

How to use this portfolio
KLA's 503 grants land it in the top 0.1% 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.
