Portfolio overview

Kabushiki Kaisha Toyota CHUO Kenkyusho has been granted 262 US utility patents between 2015 and 2025, placing Kabushiki Kaisha Toyota CHUO Kenkyusho at rank #1,578 across all assignees tracked by PlainPatent. This portfolio spans 145 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.7 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Kabushiki Kaisha Toyota CHUO Kenkyusho is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Kabushiki sits between Mitsuba Corporation (263 patents, rank #1,574) and The Lubrizol Corporation (262 patents, rank #1,582) - the closest US assignees by grant volume. The composite Innovation Score of 52.4/100 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 101 grants, compared with 161 in the 2015–2019 window, a -37% 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. Kabushiki Kaisha Toyota CHUO Kenkyusho's 9.7 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 Kabushiki Kaisha Toyota CHUO Kenkyusho against peers pursuing similar technology classes.

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.
