What this shows J.h.'s Innovation Score is 52.5/100 (top 10% 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.

Where J.h.'s grants concentrate

J.H. Fletcher & Co. is a focused PatentsView assignee: 20 CPC subclasses with 72.2% 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 2024 (3 grants) versus a trough of 1 in 2016. By volume, J.h. sits between IntraAction Corp. and JDI Design AND Development G.K..

J.h.'s three-year grant acceleration

J.H. Fletcher & Co. shows 7 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.
