As a Foreign Corporation, CHINA TOBACCO HUNAN INDUSTRIAL CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 59.7/100 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 52 grants, compared with 3 in the 2015–2019 window — a +1633% shift in five-year velocity.

CHINA TOBACCO HUNAN INDUSTRIAL CO., LTD.'s 15.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 21 subclasses balances depth with breadth.
