What this shows Asahi's Innovation Score is 61.7/100 (top 3% 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 Asahi?
Each dot is one of Asahi’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). Asahi’s own 15.0 claims/patent is ABOVE the 12.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
How Asahi's grant cadence moved
Between 2020–2024, Asahi Kasei Microdevices Corporation received 143 grants versus 84 in 2015–2019 (+70% equal-window velocity, above median growth). Across complete PatentsView years, output peaked in 2022 at 38 grants and bottomed in 2018 at 13. Lead class G01R accounts for 23.4% of the portfolio across 66 subclasses. Volume neighbours: AAC Acoustic Technologies (SHENZHEN) Co., Ltd. (#1,606) and Nexans (#1,614).
Asahi's three-year grant acceleration
From 2019–2021 to 2022–2024, Asahi Kasei Microdevices Corporation moved from 70 to 90 grants (1.29x the prior three-year total, a multiple, not a CAGR). Among 3,296 tracked assignees with ≥100 grants and ≥20 prior-period grants, that multiple ranks #667. See the growth leaderboard.
