Portfolio overview

Cancer Hospital, Chinese Academy OF Medical Sciences has been granted 9 US utility patents between 2017 and 2025, placing Cancer Hospital, Chinese Academy OF Medical Sciences at rank #28,324 across all assignees tracked by PlainPatent. This portfolio spans 11 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.9 claims per patent with primary concentration in C12Q (MEASURING OR TESTING PROCESSES INVOLVING ENZYMES, NUCLEIC ACIDS OR MICROORGANISMS ; COMPOSITIONS OR TEST PAPERS THEREFOR; PROCESSES OF PREPARING SUCH COMPOSITIONS; CONDITION-RESPONSIVE CONTROL IN MICR). As a Foreign Corporation, Cancer Hospital, Chinese Academy OF Medical Sciences is one of the more focused assignees in the PatentsView dataset. By volume, Cancer sits between Calyxia (9 patents, rank #28,320) and Car-ber Investments Inc. (9 patents, rank #28,328) - the closest US assignees by grant volume. The composite Innovation Score of 41.7/100 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 7 grants, compared with 2 in the 2015–2019 window, a +250% 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. Cancer Hospital, Chinese Academy OF Medical Sciences's 8.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 11 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Cancer Hospital, Chinese Academy OF Medical Sciences against peers pursuing similar technology classes.
