Portfolio overview

Blue Danube Systems, Inc. has been granted 25 US utility patents between 2015 and 2023, placing Blue Danube Systems, Inc. at rank #11,946 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.8 claims per patent with primary concentration in H04B (TRANSMISSION). As a US Corporation, Blue Danube Systems, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Blue sits between Bicyclerd Limited (25 patents, rank #11,942) and Brentwood Industries, Inc. (25 patents, rank #11,950) - the closest US assignees by grant volume. The composite Innovation Score of 38.5/100 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 12 grants, compared with 13 in the 2015–2019 window, a -8% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Blue Danube Systems, Inc.'s 20.8 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Blue Danube Systems, Inc. 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.
