Portfolio overview
Alpha and Omega Semiconductor (Cayman) Ltd. has been granted 133 US utility patents between 2015 and 2025, placing Alpha and Omega Semiconductor (Cayman) Ltd. at rank #2,872 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.6 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Alpha and Omega Semiconductor (Cayman) Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 45.0/100 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 72 grants, compared with 61 in the 2015–2019 window — a +18% 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. Alpha and Omega Semiconductor (Cayman) Ltd.'s 16.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, 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 Alpha and Omega Semiconductor (Cayman) Ltd. against peers pursuing similar technology classes.
