Portfolio overview

GUANGZHOU ISSYZONE TECHNOLOGY CO., LIMITED has been granted 47 US utility patents between 2020 and 2025, placing GUANGZHOU ISSYZONE TECHNOLOGY CO., LIMITED at rank #7,006 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.5 claims per patent with primary concentration in B60J (WINDOWS, WINDSCREENS, NON-FIXED ROOFS, DOORS, OR SIMILAR DEVICES FOR VEHICLES; REMOVABLE EXTERNAL PROTECTIVE COVERINGS SPECIALLY ADAPTED FOR VEHICLES). As a Foreign Corporation, GUANGZHOU ISSYZONE TECHNOLOGY CO., LIMITED is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 44.9/100 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 47 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. GUANGZHOU ISSYZONE TECHNOLOGY CO., LIMITED's 1.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark GUANGZHOU ISSYZONE TECHNOLOGY CO., LIMITED against peers pursuing similar technology classes.

How to use this portfolio

Guangzhou's 47 grants land it in the top 24% 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 — Guangzhou ranks #7,006 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in B60J — see who else leads that technology area. B60J 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.
