What this shows World's Innovation Score is 36.7/100 (top 46% 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 World?

Each dot is one of World’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). World’s own 8.4 claims/patent is at or below the 14.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where World's grants concentrate

World Richman Manufacturing Corporation is a focused PatentsView assignee: 12 CPC subclasses with 35.9% of grants classified under A45C (PURSES; LUGGAGE; Hand Carried Bags). Peak complete grant year is 2015 (8 grants) versus a trough of 1 in 2024. By volume, World sits between Vium, Inc. and Y.E. Hub Armenia LLC.

World's three-year grant acceleration

World Richman Manufacturing Corporation shows 8 grants in 2022–2024 against only 8 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.
