Portfolio overview

Stratus Technologies Ireland Ltd. has been granted 11 US utility patents between 2020 and 2025, placing Stratus Technologies Ireland Ltd. at rank #25,193 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.4 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a Foreign Corporation, Stratus Technologies Ireland Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Stratus sits between Stemrim Inc. (11 patents, rank #25,189) and SUN Medical Co., Ltd. (11 patents, rank #25,197) - the closest US assignees by grant volume. The composite Innovation Score of 45.8/100 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 2020 through 2025, with 11 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. Stratus Technologies Ireland Ltd.'s 18.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Stratus Technologies Ireland Ltd. against peers pursuing similar technology classes.
