What this shows Robert's Innovation Score is 21.7/100 (9th 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 Robert?

Each dot is one of Robert’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). Robert’s own 1.1 claims/patent is at or below the 15.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Robert's grants concentrate

Robert Welch Designs Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 2.9% of grants classified under A47G (Household OR Table Equipment). Peak complete grant year is 2021 (6 grants) versus a trough of 2 in 2017. By volume, Robert sits between Psomagen, Inc. and Scinopharm Taiwan Ltd..

Robert's three-year grant acceleration

Robert Welch Designs Ltd. shows 5 grants in 2022–2024 against only 13 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.
