What this shows Electrophor's Innovation Score is 28.2/100 (26th 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 Electrophor?

Each dot is one of Electrophor’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). Electrophor’s own 14.0 claims/patent is ABOVE the 12.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Electrophor's grants concentrate

Electrophor, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 75% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2020. By volume, Electrophor sits between EKU Power Drives GMBH and Elminda Ltd..

Electrophor's three-year grant acceleration

Electrophor, Inc. shows 1 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.
