of 50,000 tracked assignees
USPTO PatentsView assignee record - 27 granted patents across 43 technology areas, recorded in grant years 2021–2025. Grant-trend analysis is cross-referenced to USPTO Patent Public Search; it does not measure application filings, current R&D, or legal strength. Primary class: A61L (METHODS OR APPARATUS FOR STERILISING MATERIALS OR OBJECTS IN GENERAL; DISINFECTION, STERILISATION OR DEODORISATION OF AIR; CHEMICAL ASPECTS OF BANDAGES, DRESSINGS, ABSORBENT PADS OR SURGICAL ARTICLES;).
The verdict
According to USPTO PatentsView, Korea ranks #11,315 of 50,000 tracked US assignees by granted-patent volume, with 27 patents across 43 technology areas.
Korea Institute OF Materials Science has been granted 27 US utility patents between 2021 and 2025, placing Korea Institute OF Materials Science at #11,315 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 43 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.0 claims per patent with primary concentration in A61L (METHODS OR APPARATUS FOR STERILISING MATERIALS OR OBJECTS IN GENERAL; DISINFECTION, STERILISATION OR DEODORISATION OF AIR; CHEMICAL ASPECTS OF BANDAGES, DRESSINGS, ABSORBENT PADS OR SURGICAL ARTICLES;). As a Foreign Corporation, Korea Institute OF Materials Science is one of the more focused assignees in the PatentsView dataset. By volume, Korea sits between KIP CR P1 Lp (27 patents, rank #11,302) and Keeson Technology Corporation Limited (27 patents, rank #11,310) - the closest US assignees by grant volume. The composite Innovation Score of 58.1/100 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. Historical data spans 2021 through 2025, with 27 total grants over that period. 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. Korea Institute OF Materials Science's 12.0 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 43 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

How to use this portfolio
Korea's 27 grants land it in the top 5% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
