Portfolio overview

Mitutoyo Corporation has been granted 820 US utility patents between 2015 and 2025, placing Mitutoyo Corporation at rank #549 across all assignees tracked by PlainPatent. This portfolio spans 88 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.3 claims per patent with primary concentration in G01B (MEASURING LENGTH, THICKNESS OR SIMILAR LINEAR DIMENSIONS; MEASURING ANGLES; MEASURING AREAS; MEASURING IRREGULARITIES OF SURFACES OR CONTOURS). As a Foreign Corporation, Mitutoyo Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Mitutoyo sits between Kaneka Corporation (824 patents, rank #545) and LSIS Co., Ltd. (812 patents, rank #553) - the closest US assignees by grant volume. The composite Innovation Score of 58.9/100 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 384 grants, compared with 436 in the 2015–2019 window, a -12% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Mitutoyo Corporation's 11.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 88 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mitutoyo Corporation 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.
