Portfolio overview

Guangzhou Roiskin Technology Company has been granted 10 US utility patents between 2022 and 2024, placing Guangzhou Roiskin Technology Company at rank #26,383 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.3 claims per patent with primary concentration in A45C (PURSES; LUGGAGE; HAND CARRIED BAGS). As a Foreign Corporation, Guangzhou Roiskin Technology Company is one of the more focused assignees in the PatentsView dataset. By volume, Guangzhou sits between Guangdong Yingao Kitchen Utensils Co., Ltd. (10 patents, rank #26,379) and Gagemaker, Lp (10 patents, rank #26,387) - the closest US assignees by grant volume. The composite Innovation Score of 38.8/100 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 2022 through 2024, with 10 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 Roiskin Technology Company's 4.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Guangzhou Roiskin Technology Company against peers pursuing similar technology classes.

How to use this portfolio

Guangzhou's 10 grants land it in the top 40% 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 #26,383 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in A45C - see who else leads that technology area. A45C 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.
