What this shows Csignum's Innovation Score is 29.9/100 (33rd 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 Csignum?

Each dot is one of Csignum’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). Csignum’s own 13.2 claims/patent is ABOVE the 12.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Csignum's grants concentrate

CSignum Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 83.3% of grants classified under H04B (Transmission). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2023. By volume, Csignum sits between CSB-System AG and Cuchen Co., Ltd..

Csignum's three-year grant acceleration

CSignum Ltd. shows 3 grants in 2022–2024 against only 3 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.
