Portfolio overview

Changzhou Patent Electronic Technology Co., Ltd has been granted 71 US utility patents between 2018 and 2025, placing Changzhou Patent Electronic Technology Co., Ltd at rank #4,870 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.6 claims per patent with primary concentration in A24F (SMOKERS' REQUISITES; MATCH BOXES; SIMULATED SMOKING DEVICES). As a Foreign Corporation, Changzhou Patent Electronic Technology Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Changzhou sits between Bionime Corporation (71 patents, rank #4,866) and Domo, Inc. (71 patents, rank #4,874) - the closest US assignees by grant volume. The composite Innovation Score of 46.8/100 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. Between 2020 and 2025 the company received 48 grants, compared with 23 in the 2015–2019 window, a +109% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Changzhou Patent Electronic Technology Co., Ltd's 10.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Changzhou Patent Electronic Technology Co., Ltd against peers pursuing similar technology classes.

How to use this portfolio

Changzhou's 71 grants land it in the top 20% 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 - Changzhou ranks #4,870 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.
