Portfolio overview

Nippon Paint Marine Coatings Co., Ltd. has been granted 9 US utility patents between 2015 and 2024, placing Nippon Paint Marine Coatings Co., Ltd. at rank #29,544 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.6 claims per patent with primary concentration in C09D (COATING COMPOSITIONS, e.g. PAINTS, VARNISHES OR LACQUERS; FILLING PASTES; CHEMICAL PAINT OR INK REMOVERS; INKS; CORRECTING FLUIDS; WOODSTAINS; PASTES OR SOLIDS FOR COLOURING OR PRINTING; USE OF MATERI). As a Foreign Corporation, Nippon Paint Marine Coatings Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Nippon sits between Ningbo Wentai Sport Equipment Co., Ltd. (9 patents, rank #29,540) and NKT Cables Group A/s (9 patents, rank #29,548) - the closest US assignees by grant volume. The composite Innovation Score of 28.8/100 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 6 in the 2015–2019 window, a -50% 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. Nippon Paint Marine Coatings Co., Ltd.'s 11.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nippon Paint Marine Coatings Co., Ltd. against peers pursuing similar technology classes.

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.
