Portfolio overview

Minebea Co., Ltd. has been granted 214 US utility patents between 2015 and 2019, placing Minebea Co., Ltd. at rank #1,878 across all assignees tracked by PlainPatent. This portfolio spans 78 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.8 claims per patent with primary concentration in H02K (DYNAMO-ELECTRIC MACHINES). As a Foreign Corporation, Minebea Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Minebea sits between Glaxosmithkline Intellectual Property Development Limited (214 patents, rank #1,874) and St-ericsson Sa (214 patents, rank #1,882) - the closest US assignees by grant volume. The composite Innovation Score of 49.4/100 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 0 grants, compared with 214 in the 2015–2019 window, a -100% 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. Minebea Co., Ltd.'s 9.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 78 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Minebea 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.
