Portfolio overview

Speira Gmbh has been granted 9 US utility patents between 2022 and 2025, placing Speira Gmbh at rank #30,229 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.3 claims per patent with primary concentration in C22F (CHANGING THE PHYSICAL STRUCTURE OF NON-FERROUS METALS AND NON-FERROUS ALLOYS). As a Foreign Corporation, Speira Gmbh is one of the more focused assignees in the PatentsView dataset. By volume, Speira sits between Speakman Company (9 patents, rank #30,225) and Spire, Inc. (9 patents, rank #30,233) - the closest US assignees by grant volume. The composite Innovation Score of 49.9/100 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 2022 through 2025, with 9 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. Speira Gmbh's 15.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Speira Gmbh 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.
