Portfolio overview

Guangzhou China STAR Optoelectronics Semiconductor Display Technology Co., Ltd. has been granted 56 US utility patents between 2023 and 2025, placing Guangzhou China STAR Optoelectronics Semiconductor Display Technology Co., Ltd. at #6,031 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.7 claims per patent with primary concentration in 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). As a Foreign Corporation, Guangzhou China STAR Optoelectronics Semiconductor Display Technology Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Guangzhou sits between Fred Hutchinson Cancer Center (56 patents, rank #6,026) and Integrity Implants Inc. (56 patents, rank #6,034) - the closest US assignees by grant volume. The composite Innovation Score of 58.6/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Historical data spans 2023 through 2025, with 56 total grants over that period. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Guangzhou China STAR Optoelectronics Semiconductor Display Technology Co., Ltd.'s 16.7 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 17 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
