Portfolio overview

Hankookin Inc has been granted 16 US utility patents between 2017 and 2025, placing Hankookin Inc at #17,732 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.9 claims per patent with primary concentration in A61C (DENTISTRY; APPARATUS OR METHODS FOR ORAL OR DENTAL HYGIENE). As a US Corporation, Hankookin Inc is one of the more focused assignees in the PatentsView dataset. By volume, Hankookin sits between Hycor Biomedical, Llc (16 patents, rank #17,745) and Henniges Automotive Sealing Systems North America, Inc. (16 patents, rank #17,753) - the closest US assignees by grant volume. The composite Innovation Score of 49.4/100 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 6 grants, compared with 9 in the 2015–2019 window, a -33% 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 US Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Hankookin Inc's 13.9 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 17 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
