Portfolio overview

Nikkeikin Aluminium Core Technology Company, Ltd. has been granted 11 US utility patents between 2015 and 2022, placing Nikkeikin Aluminium Core Technology Company, Ltd. at rank #24,894 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 4.9 claims per patent with primary concentration in B60R (VEHICLES, VEHICLE FITTINGS, OR VEHICLE PARTS, NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Nikkeikin Aluminium Core Technology Company, Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Nikkeikin sits between Nexus Medical, Llc (11 patents, rank #24,890) and Northeast Institute Of Geography And Agroecology, Chinese Academy Of Sciences (11 patents, rank #24,898) - the closest US assignees by grant volume. The composite Innovation Score of 26.0/100 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 3 grants, compared with 8 in the 2015–2019 window, a -62% 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. Nikkeikin Aluminium Core Technology Company, Ltd.'s 4.9 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 Nikkeikin Aluminium Core Technology Company, Ltd. against peers pursuing similar technology classes.
