What this shows ENF's Innovation Score is 38.0/100 (top 42% 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 ENF?

Each dot is one of ENF’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). ENF’s own 11.4 claims/patent is at or below the 12.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where ENF's grants concentrate

ENF Technology Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 83.3% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2017. By volume, ENF sits between Embraco Industria DE Compressores E Solucoes EM Refrigeracao Ltda. and Essai, Inc..

ENF's three-year grant acceleration

ENF Technology Co., Ltd. shows 7 grants in 2022–2024 against only 6 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.
