What this shows Tower's Innovation Score is 56.2/100 (top 6% 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 Tower?

Each dot is one of Tower’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). Tower’s own 17.6 claims/patent is at or below the 18.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tower's grants concentrate

Tower Partners Semiconductor Co., Ltd. is a focused PatentsView assignee: 43 CPC subclasses with 38.1% of grants classified under H10D (Inorganic Electric Semiconductor Devices). Peak complete grant year is 2016 (15 grants) versus a trough of 3 in 2019. By volume, Tower sits between Soclean, Inc. and Xiamen Tianma Display Technology Co., Ltd..

Tower's three-year grant acceleration

Tower Partners Semiconductor Co., Ltd. shows 17 grants in 2022–2024 against only 16 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.
