Portfolio overview

Imperial Innovations Limited has been granted 111 US utility patents between 2015 and 2025, placing Imperial Innovations Limited at rank #3,348 across all assignees tracked by PlainPatent. This portfolio spans 100 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.4 claims per patent with primary concentration in A61K (PREPARATIONS FOR MEDICAL, DENTAL OR TOILETRY PURPOSES). As a Foreign Corporation, Imperial Innovations Limited is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Imperial sits between Emitec Gesellschaft Fuer Emissionstechnologie Mbh (111 patents, rank #3,344) and MUSC Foundation For Research Development (111 patents, rank #3,352) - the closest US assignees by grant volume. The composite Innovation Score of 51.8/100 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 15 grants, compared with 96 in the 2015–2019 window, a -84% 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. Imperial Innovations Limited's 15.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Imperial Innovations Limited 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.
