What this shows Stmicroelectronics's Innovation Score is 40.3/100 (top 36% 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 Stmicroelectronics?

Each dot is one of Stmicroelectronics’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). Stmicroelectronics’s own 17.3 claims/patent is ABOVE the 15.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Stmicroelectronics's grants concentrate

Stmicroelectronics (CHINA) Investment Co., Ltd is a focused PatentsView assignee: 13 CPC subclasses with 30% of grants classified under G05F (Systems FOR Regulating Electric OR Magnetic Variables). Peak complete grant year is 2017 (5 grants) versus a trough of 1 in 2018. By volume, Stmicroelectronics sits between SSI Schäfer Automation GmbH (AT) and Swiftlink Technologies Inc..

Stmicroelectronics's three-year grant acceleration

Stmicroelectronics (CHINA) Investment Co., Ltd shows 3 grants in 2022–2024 against only 3 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.
