Portfolio overview

Kolon Plastics, Inc. has been granted 7 US utility patents between 2016 and 2023, placing Kolon Plastics, Inc. at rank #36,095 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.9 claims per patent with primary concentration in C07D (HETEROCYCLIC COMPOUNDS). As a Foreign Corporation, Kolon Plastics, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Kolon sits between Klueber Lubrication Muenchen SE & Co. KG (7 patents, rank #36,091) and KORE Wireless Group, Inc. (7 patents, rank #36,099) - the closest US assignees by grant volume. The composite Innovation Score of 39.3/100 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 1 in the 2015–2019 window, a +500% 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. Kolon Plastics, Inc.'s 10.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kolon Plastics, Inc. 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.
