What this shows Semiconductor's Innovation Score is 62.2/100 (top 2% 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 Semiconductor?

Each dot is one of Semiconductor’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). Semiconductor’s own 15.3 claims/patent is at or below the 17.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Semiconductor's grant cadence moved

Between 2020–2024, Semiconductor Manufacturing International (Shanghai) Corporation received 506 grants versus 853 in 2015–2019 (-41% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2019 at 228 grants and bottomed in 2024 at 35. Lead class H01L accounts for 66.5% of the portfolio across 81 subclasses. Volume neighbours: Sabic Global Technologies B.V. (#307) and Qorvo US, Inc. (#315).

Semiconductor's three-year grant acceleration

From 2019–2021 to 2022–2024, Semiconductor Manufacturing International (Shanghai) Corporation moved from 504 to 230 grants (0.46x 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 #2,784. See the growth leaderboard.
