Portfolio overview
Oki Electric Industry Co., Ltd. has been granted 344 US utility patents between 2015 and 2025, placing Oki Electric Industry Co., Ltd. at rank #1,236 across all assignees tracked by PlainPatent. This portfolio spans 69 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.8 claims per patent with primary concentration in G07D (HANDLING OF COINS OR VALUABLE PAPERS, e.g. TESTING, SORTING BY DENOMINATIONS, COUNTING, DISPENSING, CHANGING OR DEPOSITING). As a Foreign Corporation, Oki Electric Industry Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 58.3/100 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 137 grants, compared with 207 in the 2015–2019 window — a -34% 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. Oki Electric Industry Co., Ltd.'s 10.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 69 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Oki Electric Industry Co., Ltd. against peers pursuing similar technology classes.
