What this shows World's Innovation Score is 32.4/100 (41st 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 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 17.9 claims/patent is ABOVE the 10.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where World's grants concentrate

World Energy Systems Incorporated is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2015. By volume, World sits between Whole Bath, LLC and Wuyi Hongling Indusry and Trade Co., Ltd..

World's three-year grant acceleration

World Energy Systems Incorporated shows 1 grants in 2022–2024 against only 1 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.
