Portfolio overview

GUANGDONG MEIZHI COMPRESSOR CO., LTD. has been granted 31 US utility patents between 2017 and 2025, placing GUANGDONG MEIZHI COMPRESSOR CO., LTD. at rank #10,041 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.7 claims per patent with primary concentration in F25B (REFRIGERATION MACHINES, PLANTS OR SYSTEMS; COMBINED HEATING AND REFRIGERATION SYSTEMS; HEAT PUMP SYSTEMS). As a Foreign Corporation, GUANGDONG MEIZHI COMPRESSOR CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 40.6/100 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 19 grants, compared with 12 in the 2015–2019 window, a +58% 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. GUANGDONG MEIZHI COMPRESSOR CO., LTD.'s 12.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark GUANGDONG MEIZHI COMPRESSOR CO., LTD. against peers pursuing similar technology classes.

How to use this portfolio

Guangdong's 31 grants land it in the top 35% 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 - Guangdong ranks #10,041 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in F25B - see who else leads that technology area. F25B 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.
