What this shows Birmingham's Innovation Score is 44.7/100 (top 25% 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 Birmingham's grants concentrate

Birmingham Technologies, Inc. is a focused PatentsView assignee: 21 CPC subclasses with 72.7% of grants classified under H01J (ELECTRIC DISCHARGE TUBES OR DISCHARGE LAMPS). Peak complete grant year is 2021 (4 grants) versus a trough of 2 in 2020. By volume, Birmingham sits between Biolife, L.l.c. and Bloomaker USA, Inc..

Birmingham's three-year grant acceleration

Birmingham Technologies, Inc. shows 5 grants in 2022–2024 against only 6 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.
