Does more volume mean deeper claims for Lotte?
Each dot is one of Lotte’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). Lotte’s own 8.3 claims/patent is at or below the 16.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Lotte's grants concentrate
Lotte Fine Chemical Co., Ltd. is a focused PatentsView assignee: 21 CPC subclasses with 33.3% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2016 (7 grants) versus a trough of 1 in 2019. By volume, Lotte sits between Lisnr, Inc. and LiTL LLC.
Lotte's three-year grant acceleration
Lotte Fine Chemical Co., Ltd. shows 4 grants in 2022–2024 against only 6 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.
