What this shows Saga's Innovation Score is 47.1/100 (top 19% 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 Saga?

Each dot is one of Saga’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). Saga’s own 10.1 claims/patent is at or below the 16.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Saga's grants concentrate

Saga University is a focused PatentsView assignee: 38 CPC subclasses with 24% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2016 (5 grants) versus a trough of 1 in 2017. By volume, Saga sits between Rocky Research and Seari Electric Technology Co., Ltd..

Saga's three-year grant acceleration

Saga University shows 6 grants in 2022–2024 against only 5 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.
