USPTO PatentsView assignee record - 11 granted patents across 13 technology areas, active 2015–2023. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS).
The verdict
Wuhan holds 11 US patents across 13 technology areas, rank #25,526 of 50,000 tracked assignees.
Wuhan Institute OF Physics AND Mathematics, Chinese Academy OF Sciences has been granted 11 US utility patents between 2015 and 2023, placing Wuhan Institute OF Physics AND Mathematics, Chinese Academy OF Sciences at rank #25,526 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.8 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, Wuhan Institute OF Physics AND Mathematics, Chinese Academy OF Sciences is one of the more focused assignees in the PatentsView dataset. By volume, Wuhan sits between Withsecure Corporation (11 patents, rank #25,522) and Waterway Plastics (11 patents, rank #25,530) - the closest US assignees by grant volume. The composite Innovation Score of 27.0/100 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 5 in the 2015–2019 window, a +20% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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 Institute OF Physics AND Mathematics, Chinese Academy OF Sciences's 7.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Wuhan Institute OF Physics AND Mathematics, Chinese Academy OF Sciences against peers pursuing similar technology classes.

How to use this portfolio
Wuhan's 11 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.
