What this shows Teika's Innovation Score is 41.5/100 (top 33% 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 Teika?

Each dot is one of Teika’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). Teika’s own 16.3 claims/patent is at or below the 16.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Teika's grants concentrate

Teika Pharmaceutical Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 85.7% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2021. By volume, Teika sits between Technological Educational Institute OF Crete and Teloip Inc..

Teika's three-year grant acceleration

Teika Pharmaceutical Co., Ltd. shows 2 grants in 2022–2024 against only 1 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.
