What this shows N.e.'s Innovation Score is 43.3/100 (top 28% 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 N.e.?

Each dot is one of N.e.’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). N.e.’s own 14.1 claims/patent is ABOVE the 9.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where N.e.'s grants concentrate

N.E. Chemcat Corporation is a focused PatentsView assignee: 21 CPC subclasses with 81.8% of grants classified under B01J (Chemical OR Physical Processes, e.g. Catalysis OR Colloid CHEMISTRY; Their Relevant Apparatus). Peak complete grant year is 2016 (10 grants) versus a trough of 2 in 2017. By volume, N.e. sits between Mainspring Energy, Inc. and NTT Communications Corporation.

N.e.'s three-year grant acceleration

N.E. Chemcat Corporation shows 9 grants in 2022–2024 against only 11 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.
