How China’s 49.3 Innovation Score adds up

The same four weighted components behind every Innovation Score on PlainPatent: portfolio volume, grant velocity, technology breadth, and claim depth.

What this shows China's Innovation Score is 49.3/100 (top 15% 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 China?

Each dot is one of China’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). China’s own 7.8 claims/patent is at or below the 9.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where China's grants concentrate

China Electronics Technology Group Corporation NO 44 Research Institute is a focused PatentsView assignee: 20 CPC subclasses with 25% of grants classified under Y02D (Climate Change Mitigation Technologies IN Information AND Communication Technologies [ICT], I.E. Information AND Communication Technologies Aiming AT THE Reduction OF Their OWN Energy USE). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2015. By volume, China sits between CHA University Industry-academic Cooperation Foundation and Chuzhou HKC Optoelectronics Technology Co., Ltd..

China's three-year grant acceleration

China Electronics Technology Group Corporation NO 44 Research Institute shows 7 grants in 2022–2024 against only 1 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.
