Portfolio overview

Tan Tock Seng Hospital Pte Ltd has been granted 8 US utility patents between 2016 and 2025, placing Tan Tock Seng Hospital Pte Ltd at rank #33,596 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.3 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a Foreign Corporation, Tan Tock Seng Hospital Pte Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Tan sits between Tagworks Pharmaceuticals B.v. (8 patents, rank #33,592) and Tap Systems Inc. (8 patents, rank #33,600) - the closest US assignees by grant volume. The composite Innovation Score of 46.8/100 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 2 in the 2015–2019 window, a +200% 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. Tan Tock Seng Hospital Pte Ltd's 14.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Tan Tock Seng Hospital Pte Ltd against peers pursuing similar technology classes.

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.
