What this shows Seiko's Innovation Score is 44.0/100 (top 27% 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 Seiko's grants concentrate

Seiko PMC Corporation is a focused PatentsView assignee: 16 CPC subclasses with 45.5% of grants classified under C08J (WORKING-UP; GENERAL PROCESSES OF COMPOUNDING; AFTER-TREATMENT NOT COVERED BY SUBCLASSES C08B, C08C, C08F, C08G or C08H). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2017. By volume, Seiko sits between Schottky LSI, Inc. and Semco Llc.

Seiko's three-year grant acceleration

Seiko PMC 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.
