What this shows Mercer's Innovation Score is 36.6/100 (top 46% 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 Mercer?

Each dot is one of Mercer’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). Mercer’s own 19.6 claims/patent is ABOVE the 15.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Mercer's grants concentrate

Mercer International Inc. is a focused PatentsView assignee: 15 CPC subclasses with 100% of grants classified under D21H (Pulp COMPOSITIONS; Preparation Thereof NOT Covered BY Subclasses D21c OR D21D; Impregnating OR Coating OF PAPER; Treatment OF Finished Paper NOT Covered BY Class B31 OR Subclass D21G; Paper NOT Otherw). Peak complete grant year is 2020 (9 grants) versus a trough of 1 in 2019. By volume, Mercer sits between Medical & Biological Laboratories Co., Ltd. and Metrasens Limited.

Mercer's three-year grant acceleration

Mercer International Inc. shows 3 grants in 2022–2024 against only 11 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.
