The verdict
Yamazaki holds 49 US patents across 32 technology areas, rank #6,861 of 50,000 tracked assignees.
Yamazaki Mazak Corporation has been granted 49 US utility patents between 2015 and 2025, placing Yamazaki Mazak Corporation at rank #6,861 across all assignees tracked by PlainPatent. This portfolio spans 32 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.5 claims per patent with primary concentration in B23Q (DETAILS, COMPONENTS, OR ACCESSORIES FOR MACHINE TOOLS, e.g. ARRANGEMENTS FOR COPYING OR CONTROLLING ; MACHINE TOOLS IN GENERAL CHARACTERISED BY THE CONSTRUCTION OF PARTICULAR DETAILS OR COMPONENTS; CO). As a Foreign Corporation, Yamazaki Mazak Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Yamazaki sits between W&H Dentalwerk Bürmoos Gmbh (49 patents, rank #6,857) and AC Immune Sa (48 patents, rank #6,865) - the closest US assignees by grant volume. The composite Innovation Score of 55.5/100 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 30 grants, compared with 19 in the 2015–2019 window, a +58% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Yamazaki Mazak Corporation'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 32 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Yamazaki Mazak Corporation against peers pursuing similar technology classes.

How to use this portfolio
Yamazaki's 49 grants land it in the top 7% 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.
