Portfolio overview

UACJ Corporation has been granted 178 US utility patents between 2015 and 2025, placing UACJ Corporation at rank #2,216 across all assignees tracked by PlainPatent. This portfolio spans 59 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.9 claims per patent with primary concentration in C22C (ALLOYS). As a Foreign Corporation, UACJ Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, UACJ sits between Rockley Photonics Limited (178 patents, rank #2,212) and Bright DATA Ltd. (177 patents, rank #2,220) - the closest US assignees by grant volume. The composite Innovation Score of 56.6/100 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 107 grants, compared with 71 in the 2015–2019 window, a +51% 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. UACJ Corporation's 9.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 59 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark UACJ Corporation 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.
