Portfolio overview

Nippon Pillar Packing Co., Ltd. has been granted 112 US utility patents between 2015 and 2025, placing Nippon Pillar Packing Co., Ltd. at rank #3,329 across all assignees tracked by PlainPatent. This portfolio spans 42 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.9 claims per patent with primary concentration in F16L (PIPES; JOINTS OR FITTINGS FOR PIPES; SUPPORTS FOR PIPES, CABLES OR PROTECTIVE TUBING; MEANS FOR THERMAL INSULATION IN GENERAL). As a Foreign Corporation, Nippon Pillar Packing Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Nippon sits between Global Trademarks, Inc. (112 patents, rank #3,325) and Sandisk 3D Llc (112 patents, rank #3,333) - the closest US assignees by grant volume. The composite Innovation Score of 53.0/100 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 74 grants, compared with 38 in the 2015–2019 window, a +95% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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 Pillar Packing Co., Ltd.'s 5.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 42 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nippon Pillar Packing 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.
