Patent Application for Biodegradable Particles Delivering Therapeutic Agents

This document is a publication of a patent application filed with the USPTO, specifically application US20260083830A1. It describes biodegradable microparticles and nanoparticles made from polymers like PLGA or PLA, designed to deliver positively charged therapeutic agents, such as proteins or peptides, with extended and controlled release at neutral pH. The application also covers methods for making and administering these particles.

As this is a patent application, it does not impose immediate regulatory obligations or compliance deadlines on regulated entities. However, it represents potential future intellectual property in the field of drug delivery systems. Companies involved in pharmaceutical development, particularly those working with protein or peptide therapeutics and advanced delivery mechanisms, should be aware of this filing for competitive intelligence and potential licensing opportunities.
