Portfolio overview

BEIJING SMTP TECHNOLOGY CO., LTD. has been granted 33 US utility patents between 2020 and 2024, placing BEIJING SMTP TECHNOLOGY CO., LTD. at rank #9,445 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.0 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a Foreign Corporation, BEIJING SMTP TECHNOLOGY CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 27.3/100 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 2024, with 33 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. BEIJING SMTP TECHNOLOGY CO., LTD.'s 6.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark BEIJING SMTP TECHNOLOGY CO., LTD. against peers pursuing similar technology classes.

How to use this portfolio

Beijing's 33 grants land it in the top 77% 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 #9,445 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in A61B - see who else leads that technology area. A61B 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.
