Portfolio overview

JANOME SEWING MACHINE CO., LTD. has been granted 132 US utility patents between 2015 and 2024, placing JANOME SEWING MACHINE CO., LTD. at rank #2,898 across all assignees tracked by PlainPatent. This portfolio spans 28 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.0 claims per patent with primary concentration in D05B (SEWING). As a Foreign Corporation, JANOME SEWING MACHINE CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 42.5/100 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 40 grants, compared with 92 in the 2015–2019 window — a -57% 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. JANOME SEWING MACHINE CO., LTD.'s 8.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 28 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark JANOME SEWING MACHINE CO., LTD. against peers pursuing similar technology classes.
