Does more volume mean deeper claims for Koppers?

Each dot is one of Koppers’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). Koppers’s own 26.0 claims/patent is ABOVE the 11.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Koppers's grants concentrate

Koppers Performance Chemicals, Inc. is a focused PatentsView assignee: 15 CPC subclasses with 95% of grants classified under B27K (Processes, Apparatus OR Selection OF Substances FOR Impregnating, Staining, Dyeing, Bleaching OF Wood OR Similar Materials, OR Treating OF Wood OR Similar Materials With Permeant Liquids, NOT Otherwis). Peak complete grant year is 2021 (5 grants) versus a trough of 2 in 2016. By volume, Koppers sits between Kolen Co., Ltd. and KT Health, LLC.

Koppers's three-year grant acceleration

Koppers Performance Chemicals, Inc. shows 2 grants in 2022–2024 against only 7 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.
