Portfolio overview

Citizen Finedevice Co., Ltd. has been granted 25 US utility patents between 2015 and 2025, placing Citizen Finedevice Co., Ltd. at rank #11,958 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.9 claims per patent with primary concentration in G01L (MEASURING FORCE, STRESS, TORQUE, WORK, MECHANICAL POWER, MECHANICAL EFFICIENCY, OR FLUID PRESSURE). As a Foreign Corporation, Citizen Finedevice Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Citizen sits between Capcom Co., Ltd. (25 patents, rank #11,954) and Component Hardware Group, Inc. (25 patents, rank #11,962) - the closest US assignees by grant volume. The composite Innovation Score of 36.6/100 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 14 grants, compared with 11 in the 2015–2019 window, a +27% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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 Finedevice Co., Ltd.'s 10.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Citizen Finedevice Co., Ltd. against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
