Portfolio overview

Beijing Sevenstar Electronics Co., Ltd. has been granted 7 US utility patents between 2015 and 2023, placing Beijing Sevenstar Electronics Co., Ltd. at rank #34,414 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.3 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Beijing Sevenstar Electronics Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Beijing sits between Beijing Institute FOR Cancer Research (7 patents, rank #34,410) and Bekaert Combustion Technology B.v. (7 patents, rank #34,418) - the closest US assignees by grant volume. The composite Innovation Score of 29.4/100 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 1 grants, compared with 6 in the 2015–2019 window, a -83% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Beijing Sevenstar Electronics Co., Ltd.'s 10.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Beijing Sevenstar Electronics Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio

Beijing's 7 grants land it in the top 69% 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 - Beijing ranks #34,414 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H01L - see who else leads that technology area. H01L 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.
