Portfolio overview

Hankook Tire Co., Ltd. has been granted 114 US utility patents between 2015 and 2023, placing Hankook Tire Co., Ltd. at rank #3,280 across all assignees tracked by PlainPatent. This portfolio spans 27 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.5 claims per patent with primary concentration in B60C (VEHICLE TYRES; TYRE INFLATION; TYRE CHANGING; CONNECTING VALVES TO INFLATABLE ELASTIC BODIES IN GENERAL; DEVICES OR ARRANGEMENTS RELATED TO TYRES). As a Foreign Corporation, Hankook Tire Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 38.5/100 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 28 grants, compared with 86 in the 2015–2019 window — a -67% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Hankook Tire Co., Ltd.'s 4.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 27 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hankook Tire Co., Ltd. against peers pursuing similar technology classes.
