Portfolio overview
Callaghan Innovation has been granted 7 US utility patents between 2016 and 2025, placing Callaghan Innovation at rank #34,628 across all assignees tracked by PlainPatent. This portfolio spans 9 distinct Cooperative Patent Classification (CPC) subclasses, averaging 26.4 claims per patent with primary concentration in A63F (CARD, BOARD, OR ROULETTE GAMES; INDOOR GAMES USING SMALL MOVING PLAYING BODIES; VIDEO GAMES; GAMES NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Callaghan Innovation is one of the more focused assignees in the PatentsView dataset. By volume, Callaghan sits between Cablecam, Llc (7 patents, rank #34,624) and Camlin Italy S.r.l. (7 patents, rank #34,632) - the closest US assignees by grant volume. The composite Innovation Score of 32.8/100 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. Between 2020 and 2025 the company received 3 grants, compared with 4 in the 2015–2019 window, a -25% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Callaghan Innovation's 26.4 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 9 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Callaghan Innovation against peers pursuing similar technology classes.
