Overall rank by patents
#13,582
of 50,000 tracked assignees
USPTO PatentsView assignee record - 22 granted patents across 27 technology areas, recorded in grant years 2015–2025. Grant-trend analysis is cross-referenced to USPTO Patent Public Search; it does not measure application filings, current R&D, or legal strength. Primary class: C10G (CRACKING HYDROCARBON OILS; PRODUCTION OF LIQUID HYDROCARBON MIXTURES, e.g. BY DESTRUCTIVE HYDROGENATION, OLIGOMERISATION, POLYMERISATION ; RECOVERY OF HYDROCARBON OILS FROM OIL-SHALE, OIL-SAND, OR GAS).
The verdict
According to USPTO PatentsView, Nippon ranks #13,582 of 50,000 tracked US assignees by granted-patent volume, with 22 patents across 27 technology areas.

What this shows Nippon Steel Engineering Co., Ltd stamps GRANTS-SMALL, MID-PACK, PHOTO-FINISH, CPC-FOCUS, INNOV-PAR, CLAIMS-PAR, TYPE-FRNCORP, VEL-DROP, BOOK-FULL. Volume places it #13,582 of 50,000; Innovation Score 41.8/100 sits in the top 32% of the PatentsView-derived corpus. Closest grant-volume peer on this plate is Naber Holding Gmbh & Co. (±0 grants).
Nippon Steel Engineering Co., Ltd has been granted 22 US utility patents between 2015 and 2025, placing Nippon Steel Engineering Co., Ltd at #13,582 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 27 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.8 claims per patent with primary concentration in C10G (CRACKING HYDROCARBON OILS; PRODUCTION OF LIQUID HYDROCARBON MIXTURES, e.g. BY DESTRUCTIVE HYDROGENATION, OLIGOMERISATION, POLYMERISATION ; RECOVERY OF HYDROCARBON OILS FROM OIL-SHALE, OIL-SAND, OR GAS). As a Foreign Corporation, Nippon Steel Engineering Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Nippon sits between Newlight Technologies, Inc. (22 patents, rank #13,568) and Nan Juen International Co., Ltd. (22 patents, rank #13,576) - the closest US assignees by grant volume. The composite Innovation Score of 41.8/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 6 grants, compared with 14 in the 2015–2019 window, a -57% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.
Claim depth and technology breadth describe this aggregate record. Nippon Steel Engineering Co., Ltd's 9.8 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 27 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
