About this source
USPTO classification A61M covers devices that introduce or withdraw fluids from the body: infusion pumps, catheters, syringes, inhalers, wound drainage, dialysis equipment, and fluid-handling microfluidics. Every newly published application in A61M lands in this feed, around 205 a month. Applications publish 18 months after filing. Watch this if you compete in infusion therapy or drug delivery, file freedom-to-operate analyses for medical device startups, scout acquisition targets in cardiovascular or respiratory devices, or track hospital R&D arms that are quietly patenting clinical innovations.
What changed
Belhaven BioPharma Inc. filed a new patent application with the USPTO covering intranasal dry powder epinephrine compositions. The application (filed June 18, 2025; published April 23, 2026) claims compositions combining epinephrine with citric acid-based stabilizing agents for nasal delivery, targeting conditions affecting alpha and beta-adrenergic receptors including anaphylaxis and MACE.
Pharmaceutical and drug delivery companies developing epinephrine products or intranasal formulations should review this application to assess potential blocking positions or freedom-to-operate concerns. Competitors in the anaphylaxis treatment space may face future patent exclusivity on dry powder intranasal epinephrine delivery if the application proceeds to grant.
