What this shows Electrophoretics's Innovation Score is 39.4/100 (top 38% 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 Electrophoretics?

Each dot is one of Electrophoretics’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). Electrophoretics’s own 20.8 claims/patent is ABOVE the 14.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Electrophoretics's grants concentrate

Electrophoretics Limited is a focused PatentsView assignee: 13 CPC subclasses with 83.3% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2021. By volume, Electrophoretics sits between EBM Papst Landshut GmbH and En2core Technology Inc..

Electrophoretics's three-year grant acceleration

Electrophoretics Limited shows 3 grants in 2022–2024 against only 5 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.
