What this shows Porifera's Innovation Score is 42.9/100 (top 29% 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 Porifera?

Each dot is one of Porifera’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). Porifera’s own 16.9 claims/patent is ABOVE the 14.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Porifera's grants concentrate

Porifera, Inc. is a focused PatentsView assignee: 14 CPC subclasses with 90.5% of grants classified under B01D (Separation). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2015. By volume, Porifera sits between Piramal Glass—USA, Inc. and Premier Manufacturing Group, Inc..

Porifera's three-year grant acceleration

Porifera, Inc. shows 8 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.
