Portfolio overview

ZHEJIANG TWINSEL ELECTRONIC TECHNOLOGY CO., LTD. has been granted 18 US utility patents between 2020 and 2025, placing ZHEJIANG TWINSEL ELECTRONIC TECHNOLOGY CO., LTD. at rank #16,526 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.4 claims per patent with primary concentration in F21S (NON-PORTABLE LIGHTING DEVICES; SYSTEMS THEREOF; VEHICLE LIGHTING DEVICES SPECIALLY ADAPTED FOR VEHICLE EXTERIORS). As a Foreign Corporation, ZHEJIANG TWINSEL ELECTRONIC TECHNOLOGY CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 38.1/100 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. Historical data spans 2020 through 2025, with 18 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. ZHEJIANG TWINSEL ELECTRONIC TECHNOLOGY CO., LTD.'s 1.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ZHEJIANG TWINSEL ELECTRONIC TECHNOLOGY CO., LTD. against peers pursuing similar technology classes.

How to use this portfolio

Zhejiang's 18 grants land it in the top 42% 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 - Zhejiang ranks #16,526 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in F21S - see who else leads that technology area. F21S 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.
