Does more volume mean deeper claims for Charm?

Each dot is one of Charm’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). Charm’s own 17.7 claims/patent is ABOVE the 16.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Charm's grants concentrate

Charm Sciences, Inc. is a focused PatentsView assignee: 14 CPC subclasses with 77.8% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2021 (6 grants) versus a trough of 1 in 2018. By volume, Charm sits between Crinetics Pharmaceuticals, Inc. and Chunghwa Telecom Co., Ltd..

Charm's three-year grant acceleration

Charm Sciences, Inc. shows 2 grants in 2022–2024 against only 12 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.
