USPTO PatentsView assignee record - 7 granted patents across 3 technology areas, active 2015–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES).
The verdict
Guangzhou holds 7 US patents across 3 technology areas, rank #35,498 of 50,000 tracked assignees.
Guangzhou Wondfo Biotech Co., Ltd. has been granted 7 US utility patents between 2015 and 2025, placing Guangzhou Wondfo Biotech Co., Ltd. at rank #35,498 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.9 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a Foreign Corporation, Guangzhou Wondfo Biotech Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Guangzhou sits between Guangdong Marshell Electric Vehicle Co., Ltd. (7 patents, rank #35,494) and Gadsden Coffee Company (7 patents, rank #35,502) - the closest US assignees by grant volume. The composite Innovation Score of 27.1/100 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 2 in the 2015–2019 window, a +150% 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. Guangzhou Wondfo Biotech Co., Ltd.'s 11.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Guangzhou Wondfo Biotech Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Guangzhou's 7 grants land it in the top 78% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
