Portfolio overview

Wuhan Changsheng MINE Security Technology Limited has been granted 6 US utility patents between 2017 and 2024, placing Wuhan Changsheng MINE Security Technology Limited at rank #44,025 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.3 claims per patent with primary concentration in G01V (GEOPHYSICS; GRAVITATIONAL MEASUREMENTS; DETECTING MASSES OR OBJECTS; TAGS). As a Foreign Corporation, Wuhan Changsheng MINE Security Technology Limited is one of the more focused assignees in the PatentsView dataset. By volume, Wuhan sits between Wontech Co., Ltd. (6 patents, rank #44,021) and WUXI XIVI Science AND Technology Co., Ltd. (6 patents, rank #44,029) - the closest US assignees by grant volume. The composite Innovation Score of 31.4/100 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 5 grants, compared with 1 in the 2015–2019 window, a +400% 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. Wuhan Changsheng MINE Security Technology Limited's 11.3 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 Wuhan Changsheng MINE Security Technology Limited against peers pursuing similar technology classes.

How to use this portfolio

Wuhan's 6 grants land it in the top 62% 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 - Wuhan ranks #44,025 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G01V - see who else leads that technology area. G01V 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.
