Portfolio overview
DIPSOL CHEMICALS CO., LTD. has been granted 20 US utility patents between 2015 and 2025, placing DIPSOL CHEMICALS CO., LTD. at rank #14,562 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.5 claims per patent with primary concentration in C23C (COATING METALLIC MATERIAL; COATING MATERIAL WITH METALLIC MATERIAL; SURFACE TREATMENT OF METALLIC MATERIAL BY DIFFUSION INTO THE SURFACE, BY CHEMICAL CONVERSION OR SUBSTITUTION; COATING BY VACUUM EVAP). As a Foreign Corporation, DIPSOL CHEMICALS CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 31.5/100 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 5 grants, compared with 15 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. DIPSOL CHEMICALS CO., LTD.'s 8.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark DIPSOL CHEMICALS CO., LTD. against peers pursuing similar technology classes.
