EPO published patent application EP3538077A1 titled 'Preparation of Coated Cranberry Granules with Stable Proanthocyanidins Content' filed by Dompé farmaceutici S.p.A. (Italy). The invention relates to pharmaceutical formulations using cranberry-derived proanthocyanidins with coating technology to maintain compound stability. IPC classifications indicate A61K applications (A61K 9/50, A61K 9/16, A61K 36/45). Designated states cover all EU member states and additional European patent convention countries.

Pharmaceutical and nutraceutical companies developing cranberry-based products should review the patent claims to assess freedom-to-operate implications. Drug manufacturers creating similar proanthocyanidin formulations may need to license the technology or design around the claims. No immediate compliance action is required as patents grant rights rather than impose regulatory obligations.
