Does more volume mean deeper claims for Enfield?

Each dot is one of Enfield’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). Enfield’s own 30.0 claims/patent is ABOVE the 15.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Enfield's grants concentrate

Enfield Engine Company, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under F16C (SHAFTS; Flexible SHAFTS; Elements OR Crankshaft MECHANISMS; Rotary Bodies Other Than Gearing ELEMENTS; Bearings). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2016. By volume, Enfield sits between Energenesis Biomedical Co., Ltd. and Enmotus, Inc..

Enfield's three-year grant acceleration

Enfield Engine Company, Inc. shows 1 grants in 2022–2024 against only 3 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.
