What this shows Enflex's Innovation Score is 45.9/100 (top 22% 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 Enflex?

Each dot is one of Enflex’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). Enflex’s own 8.9 claims/patent is at or below the 19.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Enflex's grants concentrate

EnFlex, Inc. is a focused PatentsView assignee: 14 CPC subclasses with 73.3% of grants classified under F25J (Liquefaction, Solidification OR Separation OF Gases OR Gaseous ; OR Liquefied GASEOUS; Mixtures BY Pressure AND Cold Treatment ; OR BY Bringing Them Into THE Supercritical State). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2021. By volume, Enflex sits between Electro Standards Laboratories and Enlighten Innovations Inc..

Enflex's three-year grant acceleration

EnFlex, Inc. shows 8 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.
