Portfolio overview

Zuiko Corporation has been granted 126 US utility patents between 2015 and 2025, placing Zuiko Corporation at rank #3,031 across all assignees tracked by PlainPatent. This portfolio spans 38 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.9 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, Zuiko Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Zuiko sits between THE Hillman Group, Inc. (126 patents, rank #3,027) and Fingerprint Cards AB (125 patents, rank #3,035) - the closest US assignees by grant volume. The composite Innovation Score of 52.2/100 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 74 grants, compared with 52 in the 2015–2019 window, a +42% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Zuiko Corporation's 8.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 38 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Zuiko Corporation against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
