The verdict
ECC holds 9 US patents across 6 technology areas, rank #28,619 of 50,000 tracked assignees.
ECC TEC MSJ Incorporated has been granted 9 US utility patents between 2021 and 2025, placing ECC TEC MSJ Incorporated at rank #28,619 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.2 claims per patent with primary concentration in F01N (GAS-FLOW SILENCERS OR EXHAUST APPARATUS FOR MACHINES OR ENGINES IN GENERAL; GAS-FLOW SILENCERS OR EXHAUST APPARATUS FOR INTERNAL-COMBUSTION ENGINES). As a US Corporation, ECC TEC MSJ Incorporated is one of the more focused assignees in the PatentsView dataset. By volume, ECC sits between Earth WALL Products, Llc (9 patents, rank #28,615) and Ecole Nationale Superieure D'arts ET Metiers (ensam) (9 patents, rank #28,623) - the closest US assignees by grant volume. The composite Innovation Score of 44.8/100 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. Historical data spans 2021 through 2025, with 9 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. ECC TEC MSJ Incorporated's 19.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ECC TEC MSJ Incorporated against peers pursuing similar technology classes.

How to use this portfolio
ECC's 9 grants land it in the top 25% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
