Portfolio overview

Educational Testing Service has been granted 110 US utility patents between 2015 and 2025, placing Educational Testing Service at rank #3,369 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.7 claims per patent with primary concentration in G09B (EDUCATIONAL OR DEMONSTRATION APPLIANCES; APPLIANCES FOR TEACHING, OR COMMUNICATING WITH, THE BLIND, DEAF OR MUTE; MODELS; PLANETARIA; GLOBES; MAPS; DIAGRAMS). As a US Corporation, Educational Testing Service is one of the more focused assignees in the PatentsView dataset. By volume, Educational sits between Albert-ludwigs-universitaet Freiburg (110 patents, rank #3,365) and Fuelcell Energy, Inc. (110 patents, rank #3,373) - the closest US assignees by grant volume. The composite Innovation Score of 44.6/100 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 52 grants, compared with 58 in the 2015–2019 window, a -10% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. Educational Testing Service's 20.7 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Educational Testing Service against peers pursuing similar technology classes.

How to use this portfolio

Educational's 110 grants land it in the top 25% 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 - Educational ranks #3,369 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G09B - see who else leads that technology area. G09B 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.
