Portfolio overview

Beijing Tiantan Hospital, Capital Medical University has been granted 6 US utility patents between 2021 and 2025, placing Beijing Tiantan Hospital, Capital Medical University at rank #39,174 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.7 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a Foreign Corporation, Beijing Tiantan Hospital, Capital Medical University is one of the more focused assignees in the PatentsView dataset. By volume, Beijing sits between Beewise Technologies Ltd (6 patents, rank #39,170) and Benefitfocus.com, Inc. (6 patents, rank #39,178) - the closest US assignees by grant volume. The composite Innovation Score of 27.6/100 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. Historical data spans 2021 through 2025, with 6 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Beijing Tiantan Hospital, Capital Medical University's 10.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Beijing Tiantan Hospital, Capital Medical University against peers pursuing similar technology classes.
