Portfolio overview

Guangxi Liugong Machinery Co., Ltd. has been granted 25 US utility patents between 2017 and 2025, placing Guangxi Liugong Machinery Co., Ltd. at rank #12,027 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.6 claims per patent with primary concentration in E02F (DREDGING; SOIL-SHIFTING). As a Foreign Corporation, Guangxi Liugong Machinery Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 35.7/100 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 21 grants, compared with 4 in the 2015–2019 window, a +425% 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. Guangxi Liugong Machinery Co., Ltd.'s 11.6 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 Guangxi Liugong Machinery Co., Ltd. against peers pursuing similar technology classes.

Guides to patent portfolio analysis

How to use this portfolio

Guangxi's 25 grants land it in the top 48% 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 - Guangxi ranks #12,027 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in E02F - see who else leads that technology area. E02F 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.
