Does more volume mean deeper claims for Nooter/eriksen?

Each dot is one of Nooter/eriksen’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). Nooter/eriksen’s own 26.8 claims/patent is ABOVE the 13.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Nooter/eriksen's grants concentrate

Nooter/Eriksen, Inc. is a focused PatentsView assignee: 25 CPC subclasses with 38.9% of grants classified under F22B (Methods OF Steam GENERATION; Steam Boilers). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2016. By volume, Nooter/eriksen sits between Ningbo VGR Electric Appliance Co., Ltd. and OCuSOFT, Inc..

Nooter/eriksen's three-year grant acceleration

Nooter/Eriksen, Inc. shows 11 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.
