Does more volume mean deeper claims for Lier?

Each dot is one of Lier’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). Lier’s own 30.3 claims/patent is ABOVE the 16.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Lier's grants concentrate

Lier Chemical Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under C07F (Acyclic, Carbocyclic OR Heterocyclic Compounds Containing Elements Other Than Carbon, Hydrogen, Halogen, Oxygen, Nitrogen, Sulfur, Selenium OR Tellurium). Peak complete grant year is 2024 (3 grants) versus a trough of 2 in 2023. By volume, Lier sits between LGC US Asset Holdings, LLC and Light Polymers Holding.

Lier's three-year grant acceleration

Lier Chemical Co., Ltd. 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.
