Rhamnolipid compositions with antibiotics, UNC Chapel Hill patent

The USPTO issued a patent grant (B2 kind code) for compositions containing rhamnolipid biosurfactants combined with antibiotics, particularly aminoglycosides like tobramycin, designed to potentiate antibiotic effects against bacterial infections. The patent covers methods, kits, and compositions using pore-forming biosurfactants with cell wall-hydrolyzing enzymes.

Affected parties including pharmaceutical manufacturers, antibiotic developers, and biotechnology companies should evaluate whether their research and development activities may require licensing from UNC Chapel Hill. Generic drug manufacturers and developers of novel antimicrobial combination therapies should conduct thorough freedom-to-operate analyses to avoid potential infringement claims.
