What this shows Membrane's Innovation Score is 54.9/100 (top 7% 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 Membrane?

Each dot is one of Membrane’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). Membrane’s own 20.9 claims/patent is ABOVE the 11.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Membrane's grants concentrate

Membrane Technology and Research, Inc. is a focused PatentsView assignee: 22 CPC subclasses with 91.7% of grants classified under B01D (Separation). Peak complete grant year is 2015 (10 grants) versus a trough of 1 in 2020. By volume, Membrane sits between Malaysian Palm Oil Board and Multimatic Inc..

Membrane's three-year grant acceleration

Membrane Technology and Research, Inc. shows 6 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.
