What this shows Saraya's Innovation Score is 40.0/100 (top 37% 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 Saraya?

Each dot is one of Saraya’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). Saraya’s own 10.4 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Saraya's grants concentrate

Saraya Co., Ltd. is a focused PatentsView assignee: 21 CPC subclasses with 50% of grants classified under A61L (Methods OR Apparatus FOR Sterilising Materials OR Objects IN GENERAL; Disinfection, Sterilisation OR Deodorisation OF AIR; Chemical Aspects OF Bandages, Dressings, Absorbent Pads OR Surgical ARTICLES;). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2023. By volume, Saraya sits between Rubius Therapeutics, Inc. and School Juridical Person THE Kitasato Institute.

Saraya's three-year grant acceleration

Saraya Co., Ltd. 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.
