What this shows ECC's Innovation Score is 44.8/100 (top 25% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for ECC?

Each dot is one of ECC’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). ECC’s own 19.2 claims/patent is ABOVE the 11.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where ECC's grants concentrate

ECC TEC MSJ Incorporated is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under F01N (Gas-flow Silencers OR Exhaust Apparatus FOR Machines OR Engines IN GENERAL; Gas-flow Silencers OR Exhaust Apparatus FOR Internal-combustion Engines). Peak complete grant year is 2024 (3 grants) versus a trough of 2 in 2021. By volume, ECC sits between Earth Wall Products, LLC and Ecole Nationale Superieure D'arts ET Metiers (ENSAM).

ECC's three-year grant acceleration

ECC TEC MSJ Incorporated shows 5 grants in 2022–2024 against only 2 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
