Portfolio overview

Yunnan Academy Of Tobacco Agricultural Sciences has been granted 7 US utility patents between 2019 and 2025, placing Yunnan Academy Of Tobacco Agricultural Sciences at rank #38,388 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.9 claims per patent with primary concentration in C12N (MICROORGANISMS OR ENZYMES; COMPOSITIONS THEREOF; PROPAGATING, PRESERVING, OR MAINTAINING MICROORGANISMS; MUTATION OR GENETIC ENGINEERING; CULTURE MEDIA). As a Foreign Corporation, Yunnan Academy Of Tobacco Agricultural Sciences is one of the more focused assignees in the PatentsView dataset. By volume, Yunnan sits between Yost Labs Inc. (7 patents, rank #38,384) and Zenith Innovation, Llc (7 patents, rank #38,392) - the closest US assignees by grant volume. The composite Innovation Score of 43.1/100 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 6 grants, compared with 1 in the 2015–2019 window, a +500% 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. Yunnan Academy Of Tobacco Agricultural Sciences's 8.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Yunnan Academy Of Tobacco Agricultural Sciences against peers pursuing similar technology classes.
