What this shows Xl-protein's Innovation Score is 36.3/100 (top 47% 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 Xl-protein?

Each dot is one of Xl-protein’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). Xl-protein’s own 25.8 claims/patent is ABOVE the 9.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Xl-protein's grants concentrate

Xl-protein GMBH is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under C07K (Peptides). By volume, Xl-protein sits between Xiamen Kingqueen Industrial Co., Ltd. and Xuzhou Zhirun Mining Equipment Science AND Technology Co., Ltd.

Xl-protein's three-year grant acceleration

Xl-protein GMBH shows 2 grants in 2022–2024 against only 2 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.
