Portfolio overview

Chang Gung Memorial Hospital, Linkou has been granted 32 US utility patents between 2016 and 2024, placing Chang Gung Memorial Hospital, Linkou at #9,733 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 24 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.9 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a Foreign Corporation, Chang Gung Memorial Hospital, Linkou is one of the more focused assignees in the PatentsView dataset. By volume, Chang sits between CPI CARD Group-colorado, Inc. (32 patents, rank #9,735) and Convergent Dental, Inc. (32 patents, rank #9,743) - the closest US assignees by grant volume. The composite Innovation Score of 40.6/100 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 22 grants, compared with 10 in the 2015–2019 window, a +120% 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. Chang Gung Memorial Hospital, Linkou's 9.9 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 24 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
