Portfolio overview
WUHAN CHINA STAR OPTOELECTRONICS TECHNOLOGY CO., LTD. has been granted 1,572 US utility patents between 2016 and 2025, placing WUHAN CHINA STAR OPTOELECTRONICS TECHNOLOGY CO., LTD. at rank #272 across all assignees tracked by PlainPatent. This portfolio spans 113 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.2 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, WUHAN CHINA STAR OPTOELECTRONICS TECHNOLOGY CO., LTD. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 61.7/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Filing cadence tells the strategic story. Between 2020 and 2025 the company received 838 grants, compared with 734 in the 2015–2019 window — a +14% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.
Claim depth and technology breadth together indicate competitive posture. WUHAN CHINA STAR OPTOELECTRONICS TECHNOLOGY CO., LTD.'s 13.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark WUHAN CHINA STAR OPTOELECTRONICS TECHNOLOGY CO., LTD. against peers pursuing similar technology classes.
