What this shows Photoscience's Innovation Score is 38.6/100 (top 40% 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 Photoscience's grants concentrate

Photoscience Japan Corporation is a focused PatentsView assignee: 10 CPC subclasses with 57.1% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2018. By volume, Photoscience sits between PFG IP LLC and Ping4 Inc..

Photoscience's three-year grant acceleration

Photoscience Japan Corporation shows 4 grants in 2022–2024 against only 2 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.
