Portfolio overview
TOKIN CORPORATION has been granted 61 US utility patents between 2015 and 2025, placing TOKIN CORPORATION at rank #5,633 across all assignees tracked by PlainPatent. This portfolio spans 39 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.5 claims per patent with primary concentration in H01F (MAGNETS; INDUCTANCES; TRANSFORMERS; SELECTION OF MATERIALS FOR THEIR MAGNETIC PROPERTIES). As a Foreign Corporation, TOKIN CORPORATION is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 47.7/100 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 43 grants, compared with 18 in the 2015–2019 window — a +139% 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. TOKIN CORPORATION's 10.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 39 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark TOKIN CORPORATION against peers pursuing similar technology classes.
