USPTO PatentsView assignee record - 11 granted patents across 7 technology areas, active 2016–2024. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: C10M (LUBRICATING COMPOSITIONS ; USE OF CHEMICAL SUBSTANCES EITHER ALONE OR AS LUBRICATING INGREDIENTS IN A LUBRICATING COMPOSITION).
The verdict
KH holds 11 US patents across 7 technology areas, rank #24,623 of 50,000 tracked assignees.
KH Neochem Co., Ltd. has been granted 11 US utility patents between 2016 and 2024, placing KH Neochem Co., Ltd. at rank #24,623 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.5 claims per patent with primary concentration in C10M (LUBRICATING COMPOSITIONS ; USE OF CHEMICAL SUBSTANCES EITHER ALONE OR AS LUBRICATING INGREDIENTS IN A LUBRICATING COMPOSITION). As a Foreign Corporation, KH Neochem Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, KH sits between Kapman AB (11 patents, rank #24,619) and Kitamura Machinery Co., Ltd. (11 patents, rank #24,627) - the closest US assignees by grant volume. The composite Innovation Score of 26.3/100 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 4 grants, compared with 7 in the 2015–2019 window, a -43% 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. KH Neochem Co., Ltd.'s 6.5 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 KH Neochem Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
KH's 11 grants land it in the top 80% 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.
