Portfolio overview

Chengdu Vistar Optoelectronics Co., Ltd. has been granted 17 US utility patents between 2021 and 2025, placing Chengdu Vistar Optoelectronics Co., Ltd. at #16,679 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.3 claims per patent with primary concentration in H10H (INORGANIC LIGHT-EMITTING SEMICONDUCTOR DEVICES HAVING POTENTIAL BARRIERS). As a Foreign Corporation, Chengdu Vistar Optoelectronics Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Chengdu sits between Cellular Dynamics International, Inc. (17 patents, rank #16,690) and Chr. Hansen HMO Gmbh (17 patents, rank #16,698) - the closest US assignees by grant volume. The composite Innovation Score of 52.0/100 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 2021 through 2025, with 17 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. Chengdu Vistar Optoelectronics Co., Ltd.'s 16.3 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 12 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

How to use this portfolio

Chengdu's 17 grants land it in the top 11% 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 - Chengdu ranks #16,679 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H10H - see who else leads that technology area. H10H 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.
