What this shows Prologium's Innovation Score is 42.0/100 (top 32% 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 Prologium?

Each dot is one of Prologium’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). Prologium’s own 15.6 claims/patent is ABOVE the 15.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Prologium's grants concentrate

Prologium Holding Inc. is a focused PatentsView assignee: 13 CPC subclasses with 97.7% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2024 (8 grants) versus a trough of 1 in 2016. By volume, Prologium sits between OTI Lumionics Inc. and Pivotal Commware, Inc..

Prologium's three-year grant acceleration

Prologium Holding Inc. shows 17 grants in 2022–2024 against only 17 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.
