Does more volume mean deeper claims for Exfo?
Each dot is one of Exfo’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). Exfo’s own 18.4 claims/patent is ABOVE the 12.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Exfo's grants concentrate
Exfo Solutions SAS is a focused PatentsView assignee: 7 CPC subclasses with 83.3% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2022 (8 grants) versus a trough of 1 in 2024. By volume, Exfo sits between EPC Natural Products Co., Ltd. and Eliantte Group Inc..
Exfo's three-year grant acceleration
Exfo Solutions SAS shows 13 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.
