What this shows Opto's Innovation Score is 32.9/100 (43rd percentile 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 Opto?

Each dot is one of Opto’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). Opto’s own 12.4 claims/patent is ABOVE the 9.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Opto's grants concentrate

Opto Tech Corp. is a focused PatentsView assignee: 11 CPC subclasses with 71.4% of grants classified under H10H (Inorganic Light-emitting Semiconductor Devices Having Potential Barriers). Peak complete grant year is 2018 (6 grants) versus a trough of 1 in 2015. By volume, Opto sits between OIL Crops Research Institute, Chinese Academy OF Agricultural Sciences and Osaka GAS Chemicals Co., Ltd..

Opto's three-year grant acceleration

Opto Tech Corp. shows 2 grants in 2022–2024 against only 3 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.
