What this shows Siltectra's Innovation Score is 43.8/100 (top 27% 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 Siltectra?

Each dot is one of Siltectra’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). Siltectra’s own 16.5 claims/patent is ABOVE the 7.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
