Portfolio overview

Daicel Corporation has been granted 517 US utility patents between 2015 and 2025, placing Daicel Corporation at rank #874 across all assignees tracked by PlainPatent. This portfolio spans 160 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.8 claims per patent with primary concentration in B60R (VEHICLES, VEHICLE FITTINGS, OR VEHICLE PARTS, NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Daicel Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Daicel sits between Micromass UK Limited (519 patents, rank #870) and DISH Network L.l.c. (516 patents, rank #878) - the closest US assignees by grant volume. The composite Innovation Score of 59.1/100 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 343 grants, compared with 174 in the 2015–2019 window, a +97% 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. Daicel Corporation's 11.8 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 Daicel Corporation against peers pursuing similar technology classes.

How to use this portfolio

Daicel's 517 grants land it in the top 4% 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 - Daicel ranks #874 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in B60R - see who else leads that technology area. B60R 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.
