Portfolio overview
RAKUTEN KOBO INC. has been granted 64 US utility patents between 2016 and 2025, placing RAKUTEN KOBO INC. at rank #5,395 across all assignees tracked by PlainPatent. This portfolio spans 26 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.4 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a Foreign Corporation, RAKUTEN KOBO INC. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 44.2/100 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 13 grants, compared with 51 in the 2015–2019 window — a -75% 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. RAKUTEN KOBO INC.'s 18.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 26 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark RAKUTEN KOBO INC. against peers pursuing similar technology classes.
