Portfolio overview

Starklab has been granted 6 US utility patents between 2021 and 2023, placing Starklab at rank #42,986 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 24.3 claims per patent with primary concentration in B01D (SEPARATION). As a Foreign Corporation, Starklab is one of the more focused assignees in the PatentsView dataset. By volume, Starklab sits between STAR BP, Inc. (6 patents, rank #42,982) and State GRID Jibei Electric Power Company Limited (6 patents, rank #42,990) - the closest US assignees by grant volume. The composite Innovation Score of 47.4/100 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. Historical data spans 2021 through 2023, with 6 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. Starklab's 24.3 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Starklab against peers pursuing similar technology classes.

How to use this portfolio

Starklab's 6 grants land it in the top 19% 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 - Starklab ranks #42,986 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in B01D - see who else leads that technology area. B01D 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.
