Portfolio overview

SHENZHEN KANGER TECHNOLOGY CO., LTD has been granted 23 US utility patents between 2017 and 2021, placing SHENZHEN KANGER TECHNOLOGY CO., LTD at rank #13,140 across all assignees tracked by PlainPatent. This portfolio spans 8 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.7 claims per patent with primary concentration in A24F (SMOKERS' REQUISITES; MATCH BOXES; SIMULATED SMOKING DEVICES). As a Foreign Corporation, SHENZHEN KANGER TECHNOLOGY CO., LTD is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 27.4/100 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. Between 2020 and 2025 the company received 9 grants, compared with 14 in the 2015–2019 window, a -36% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. SHENZHEN KANGER TECHNOLOGY CO., LTD's 10.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 8 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SHENZHEN KANGER TECHNOLOGY CO., LTD against peers pursuing similar technology classes.

Guides to patent portfolio analysis

How to use this portfolio

Shenzhen's 23 grants land it in the top 76% 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 - Shenzhen ranks #13,140 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in A24F - see who else leads that technology area. A24F 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.
