What this shows Mersen's Innovation Score is 31.6/100 (38th 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 Mersen?

Each dot is one of Mersen’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). Mersen’s own 12.7 claims/patent is at or below the 12.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Mersen's grants concentrate

Mersen France SB SAS is a focused PatentsView assignee: 10 CPC subclasses with 58.3% of grants classified under H01H (Electric SWITCHES; RELAYS; SELECTORS; Emergency Protective Devices). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2015. By volume, Mersen sits between Melitta Single Portions GMBH & Co. KG and Micro Matic A/S.

Mersen's three-year grant acceleration

Mersen France SB SAS shows 3 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.
