Portfolio overview

Korea Pallet Pool Co., Ltd has been granted 9 US utility patents between 2017 and 2023, placing Korea Pallet Pool Co., Ltd at rank #29,216 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 3.8 claims per patent with primary concentration in C08K (Use of inorganic or non-macromolecular organic substances as compounding ingredients). As a Foreign Corporation, Korea Pallet Pool Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Korea sits between Kobe Bio Robotix Co., Ltd. (9 patents, rank #29,212) and Kronoplus Limited (9 patents, rank #29,220) - the closest US assignees by grant volume. The composite Innovation Score of 26.2/100 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 6 grants, compared with 3 in the 2015–2019 window, a +100% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Korea Pallet Pool Co., Ltd's 3.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Korea Pallet Pool Co., Ltd against peers pursuing similar technology classes.

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.
