Portfolio overview

Kla-tencor Technologies Corp. has been granted 10 US utility patents between 2015 and 2022, placing Kla-tencor Technologies Corp. at rank #26,664 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 45.0 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-tencor Technologies Corp. is one of the more focused assignees in the PatentsView dataset. By volume, Kla-tencor sits between KING LAI Hygienic Materials Co., Ltd (10 patents, rank #26,660) and Kobayashi & Co., Ltd. (10 patents, rank #26,668) - the closest US assignees by grant volume. The composite Innovation Score of 37.8/100 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. Between 2020 and 2025 the company received 3 grants, compared with 7 in the 2015–2019 window, a -57% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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-tencor Technologies Corp.'s 45.0 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kla-tencor Technologies Corp. against peers pursuing similar technology classes.
