Portfolio overview

Kubota Corporation has been granted 1,340 US utility patents between 2015 and 2025, placing Kubota Corporation at rank #322 across all assignees tracked by PlainPatent. This portfolio spans 164 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.2 claims per patent with primary concentration in B60K (ARRANGEMENT OR MOUNTING OF PROPULSION UNITS OR OF TRANSMISSIONS IN VEHICLES; ARRANGEMENT OR MOUNTING OF PLURAL DIVERSE PRIME-MOVERS IN VEHICLES; AUXILIARY DRIVES FOR VEHICLES; INSTRUMENTATION OR DASHB). As a Foreign Corporation, Kubota Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Kubota sits between Exxonmobil Chemical Patents Inc. (1,350 patents, rank #318) and Salesforce, Inc. (1,318 patents, rank #326) - the closest US assignees by grant volume. The composite Innovation Score of 64.7/100 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. Between 2020 and 2025 the company received 907 grants, compared with 433 in the 2015–2019 window, a +109% 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. Kubota Corporation's 10.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kubota Corporation against peers pursuing similar technology classes.

How to use this portfolio

Kubota's 1,340 grants land it in the top 1% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Kubota ranks #322 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in B60K - see who else leads that technology area. B60K leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
