What this shows Xoma's Innovation Score is 39.0/100 (top 39% 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 Xoma?

Each dot is one of Xoma’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). Xoma’s own 23.9 claims/patent is ABOVE the 14.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Xoma's grants concentrate

Xoma Technology Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 95.5% of grants classified under C07K (Peptides). Peak complete grant year is 2015 (9 grants) versus a trough of 1 in 2016. By volume, Xoma sits between X-body, Inc. and Xiamen Sheep Anti-Fatigue Mat Co., Ltd..

Xoma's three-year grant acceleration

Xoma Technology Ltd. shows 2 grants in 2022–2024 against only 5 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.
