What this shows Powerphotonic's Innovation Score is 40.1/100 (top 36% 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 Powerphotonic?

Each dot is one of Powerphotonic’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). Powerphotonic’s own 14.8 claims/patent is ABOVE the 8.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Powerphotonic's grants concentrate

Powerphotonic Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 50% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2015. By volume, Powerphotonic sits between Polymics, Ltd. and Powervision Tech Inc..

Powerphotonic's three-year grant acceleration

Powerphotonic Ltd. shows 2 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.
