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. By volume, Wuhan sits between Henkel Ag & Co. Kgaa (1,592 patents, rank #268) and Goodrich Corporation (1,557 patents, rank #276) - the closest US assignees by grant volume. 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.

How to use this portfolio

Wuhan's 1,572 grants land it in the top 3% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Wuhan ranks #272 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G02F - see who else leads that technology area. G02F leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
