Q: Is Guangzhou China Star Optoelectronics Semiconductor Display Technology Co., Ltd.'s patent grant rate increasing or decreasing?

Insufficient historical data is available to calculate a velocity trend for Guangzhou China Star Optoelectronics Semiconductor Display Technology Co., Ltd..

Q: How is the Guangzhou China Star Optoelectronics Semiconductor Display Technology Co., Ltd. patent data sourced?

All patent data comes from USPTO PatentsView, a public research dataset maintained by the United States Patent and Trademark Office covering US granted utility patents from 2015 to 2025.

USPTO PatentsView assignee record - 56 granted patents across 17 technology areas, recorded in grant years 2023–2025. Grant-trend analysis is cross-referenced to USPTO Patent Public Search; it does not measure application filings, current R&D, or legal strength. Primary class: G02F (Optical Devices OR Arrangements FOR THE Control OF Light BY Modification OF THE Optical Properties OF THE Media OF THE Elements Involved THEREIN; Non-linear OPTICS; Frequency-changing OF LIGHT; Optica).

What this shows Guangzhou's Innovation Score is 58.6/100 (top 4% 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 Guangzhou?

Each dot is one of Guangzhou’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). Guangzhou’s own 16.7 claims/patent is at or below the 17.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Guangzhou's grants concentrate

Guangzhou China Star Optoelectronics Semiconductor Display Technology Co., Ltd. is a focused PatentsView assignee: 17 CPC subclasses with 51.8% of grants classified under G02F (Optical Devices OR Arrangements FOR THE Control OF Light BY Modification OF THE Optical Properties OF THE Media OF THE Elements Involved THEREIN; Non-linear OPTICS; Frequency-changing OF LIGHT; Optica). Peak complete grant year is 2024 (16 grants) versus a trough of 3 in 2023. By volume, Guangzhou sits between Fred Hutchinson Cancer Center and Integrity Implants Inc..

Guangzhou's three-year grant acceleration

Guangzhou China Star Optoelectronics Semiconductor Display Technology Co., Ltd. shows 19 grants in 2022–2024 against only 0 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.
