Portfolio overview

Kennametal Inc. has been granted 512 US utility patents between 2015 and 2025, placing Kennametal Inc. at rank #886 across all assignees tracked by PlainPatent. This portfolio spans 79 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.5 claims per patent with primary concentration in B23B (TURNING; BORING). As a US Corporation, Kennametal Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Kennametal sits between CFPH, Llc (514 patents, rank #882) and Entegris, Inc. (509 patents, rank #890) - the closest US assignees by grant volume. The composite Innovation Score of 60.1/100 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 184 grants, compared with 328 in the 2015–2019 window, a -44% 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. Kennametal Inc.'s 15.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 79 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kennametal Inc. against peers pursuing similar technology classes.

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.
