What this shows Sanyo's Innovation Score is 57.1/100 (top 5% 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 Sanyo?

Each dot is one of Sanyo’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). Sanyo’s own 10.3 claims/patent is at or below the 11.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Sanyo's grant cadence moved

Between 2020–2024, Sanyo Chemical Industries, Ltd. received 39 grants versus 49 in 2015–2019 (-20% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2016 at 13 grants and bottomed in 2020 at 4. Lead class C08G accounts for 35.1% of the portfolio across 52 subclasses. Volume neighbours: Mitsuboshi Belting Ltd. (#3,853) and SoundHound, Inc. (#3,861).

Sanyo's three-year grant acceleration

Sanyo Chemical Industries, Ltd. shows 29 grants in 2022–2024 against only 19 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.
