What this shows Shenzhen's Innovation Score is 27.4/100 (24th percentile 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 Shenzhen?
Each dot is one of Shenzhen’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). Shenzhen’s own 5.8 claims/patent is ABOVE the 4.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
