Portfolio overview

Span.io, Inc. has been granted 9 US utility patents between 2022 and 2025, placing Span.io, Inc. at rank #30,224 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 28.2 claims per patent with primary concentration in H02J (CIRCUIT ARRANGEMENTS OR SYSTEMS FOR SUPPLYING OR DISTRIBUTING ELECTRIC POWER; SYSTEMS FOR STORING ELECTRIC ENERGY). As a US Corporation, Span.io, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Span.io sits between Sonomaceuticals, Llc (9 patents, rank #30,220) and Speedata Ltd. (9 patents, rank #30,228) - the closest US assignees by grant volume. The composite Innovation Score of 55.7/100 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 2022 through 2025, with 9 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The US 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. Span.io, Inc.'s 28.2 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Span.io, Inc. against peers pursuing similar technology classes.
