What changed
The EPO published European patent application EP4186545A1, filed by Antares Pharma, Inc., covering needle-assisted jet injection administration of testosterone compositions. The application includes nine IPC classifications spanning medical injection devices (A61M 5/20, 5/32, 5/42, 5/30) and pharmaceutical compositions (A61K 31/568, 31/56, 47/00, 9/00), indicating a combination drug-device product.
Pharmaceutical and medical device companies developing testosterone delivery systems or jet injection technologies should review the patent claims for potential overlap with their own R&D programs. The designation of 31 European contracting states means the patent, if granted, would provide protection across major European markets.
