USPTO PatentsView assignee record - 9 granted patents across 5 technology areas, active 2017–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS).
The verdict
Guangzhou holds 9 US patents across 5 technology areas, rank #28,854 of 50,000 tracked assignees.
Guangzhou Maxinovel Pharmaceuticals Co., Ltd. has been granted 9 US utility patents between 2017 and 2025, placing Guangzhou Maxinovel Pharmaceuticals Co., Ltd. at rank #28,854 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.4 claims per patent with primary concentration in A61P (SPECIFIC THERAPEUTIC ACTIVITY OF CHEMICAL COMPOUNDS OR MEDICINAL PREPARATIONS). As a Foreign Corporation, Guangzhou Maxinovel Pharmaceuticals Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Guangzhou sits between Guangdong Travelmall Health Technology Co., Ltd. (9 patents, rank #28,850) and Gunite Corporation (9 patents, rank #28,858) - the closest US assignees by grant volume. The composite Innovation Score of 30.2/100 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 6 grants, compared with 3 in the 2015–2019 window, a +100% 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 Maxinovel Pharmaceuticals Co., Ltd.'s 19.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Guangzhou Maxinovel Pharmaceuticals Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Guangzhou's 9 grants land it in the top 67% 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.
