Portfolio overview

Angel Co., Ltd. has been granted 221 US utility patents between 2021 and 2025, placing Angel Co., Ltd. at rank #1,827 across all assignees tracked by PlainPatent. This portfolio spans 32 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.1 claims per patent with primary concentration in G07F (COIN-FREED OR LIKE APPARATUS). As a Foreign Corporation, Angel Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Angel sits between Leviton Manufacturing Co., Inc. (222 patents, rank #1,823) and Royal Bank Of Canada (221 patents, rank #1,831) - the closest US assignees by grant volume. The composite Innovation Score of 68.9/100 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. Historical data spans 2021 through 2025, with 221 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Angel Co., Ltd.'s 17.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 32 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Angel 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.
