What this shows Tamron's Innovation Score is 45.3/100 (top 23% 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 Tamron?

Each dot is one of Tamron’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). Tamron’s own 9.9 claims/patent is at or below the 15.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tamron's grants concentrate

Tamron Co., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 87.4% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2017 (17 grants) versus a trough of 2 in 2018. By volume, Tamron sits between Sumitomo Electric Sintered Alloy, Ltd. and Winview, Inc..

Tamron's three-year grant acceleration

Tamron Co., Ltd. shows 24 grants in 2022–2024 against only 18 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.
