What this shows Epsitau's Innovation Score is 28.9/100 (29th 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 Epsitau?

Each dot is one of Epsitau’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). Epsitau’s own 24.0 claims/patent is ABOVE the 15.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Epsitau's grants concentrate

Epsitau Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under H01F (MAGNETS; INDUCTANCES; TRANSFORMERS; Selection OF Materials FOR Their Magnetic Properties). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2024. By volume, Epsitau sits between Epic Solutions, Inc. and Eric Beare Associates Limited.

Epsitau's three-year grant acceleration

Epsitau Ltd. 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.
