What this shows Enxl's Innovation Score is 34.5/100 (48th percentile 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 Enxl?

Each dot is one of Enxl’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). Enxl’s own 18.8 claims/patent is ABOVE the 13.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Enxl's grants concentrate

Enxl LLC is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under B01D (Separation). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2022. By volume, Enxl sits between Entuity Limited and Epec OY.

Enxl's three-year grant acceleration

Enxl LLC shows 3 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.
