Does more volume mean deeper claims for PSK?
Each dot is one of PSK’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). PSK’s own 13.8 claims/patent is at or below the 14.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where PSK's grants concentrate
PSK Inc. is a focused PatentsView assignee: 7 CPC subclasses with 75% of grants classified under H01J (Electric Discharge Tubes OR Discharge Lamps). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2015. By volume, PSK sits between Permobil AB and Polares Medical Inc..
PSK's three-year grant acceleration
PSK Inc. shows 7 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.
