What this shows Ems-chemie's Innovation Score is 51.8/100 (top 11% 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 Ems-chemie?

Each dot is one of Ems-chemie’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). Ems-chemie’s own 20.0 claims/patent is ABOVE the 12.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ems-chemie's grants concentrate

Ems-chemie AG is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under C08L (Compositions OF Macromolecular Compounds). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2015. By volume, Ems-chemie sits between Election Systems & Software, LLC and EOS of North America, Inc..

Ems-chemie's three-year grant acceleration

Ems-chemie AG shows 5 grants in 2022–2024 against only 0 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.
