Does more volume mean deeper claims for E-ray?

Each dot is one of E-ray’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). E-ray’s own 11.2 claims/patent is ABOVE the 10.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where E-ray's grants concentrate

E-ray Optoelectronics Technology Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under H10K (Organic Electric Solid-state Devices). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2015. By volume, E-ray sits between Druggability Technologies IP Holdco Limited and Easy Sanitary Solutions B.V..

E-ray's three-year grant acceleration

E-ray Optoelectronics Technology Co., Ltd. shows 1 grants in 2022–2024 against only 2 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.
