Portfolio overview

Citizen Holdings Co., Ltd. has been granted 154 US utility patents between 2015 and 2019, placing Citizen Holdings Co., Ltd. at rank #2,524 across all assignees tracked by PlainPatent. This portfolio spans 73 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.2 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Citizen Holdings Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 47.3/100 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 0 grants, compared with 154 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. Citizen Holdings Co., Ltd.'s 8.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 73 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Citizen Holdings Co., Ltd. against peers pursuing similar technology classes.
