What this shows National University Hospital (singapore) Pte Ltd stamps GRANTS-MICRO, MID-PACK, PHOTO-FINISH, CPC-FOCUS, INNOV-PAR, CLAIMS-DENSE, TYPE-FRNCORP, VEL-SURGE, BOOK-FULL. Volume places it #16,222 of 50,000; Innovation Score 46.6/100 sits in the top 20% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is Nanjing Hydraulic Research Institute (±0 grants).
National University Hospital (singapore) Pte Ltd has been granted 18 US utility patents between 2017 and 2025, placing National University Hospital (singapore) Pte Ltd at #16,222 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 22.0 claims per patent with primary concentration in A61F (FILTERS IMPLANTABLE INTO BLOOD VESSELS; PROSTHESES; DEVICES PROVIDING PATENCY TO, OR PREVENTING COLLAPSING OF, TUBULAR STRUCTURES OF THE BODY, e.g. STENTS; ORTHOPAEDIC, NURSING OR CONTRACEPTIVE DEVICE). As a Foreign Corporation, National University Hospital (singapore) Pte Ltd is one of the more focused assignees in the PatentsView dataset. By volume, National sits between Nanjing Hydraulic Research Institute (18 patents, rank #16,230) and Netskrt Systems, Inc. (18 patents, rank #16,238) - the closest US assignees by grant volume. The composite Innovation Score of 46.6/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 12 grants, compared with 4 in the 2015–2019 window, a +200% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.
Claim depth and technology breadth describe this aggregate record. National University Hospital (singapore) Pte Ltd's 22.0 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 22 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
