Portfolio overview
OIL CHEM Technologies has been granted 5 US utility patents between 2017 and 2023, placing OIL CHEM Technologies at rank #49,264 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.6 claims per patent with primary concentration in C09K (MATERIALS FOR MISCELLANEOUS APPLICATIONS, NOT PROVIDED FOR ELSEWHERE). As a US Corporation, OIL CHEM Technologies is one of the more focused assignees in the PatentsView dataset. By volume, OIL sits between Officine Metallurgiche G. Cornaglia S.p.a. (5 patents, rank #49,260) and OM Digital Solutions Corporation (5 patents, rank #49,268) - the closest US assignees by grant volume. The composite Innovation Score of 22.2/100 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 4 grants, compared with 1 in the 2015–2019 window, a +300% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The US 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. OIL CHEM Technologies's 14.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark OIL CHEM Technologies against peers pursuing similar technology classes.

- Most of this portfolio concentrates in C09K - see who else leads that technology area. C09K leaders
- Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works
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.
