ABSTRACT
The aim of this study was to analyze features of thepatent researches of nanotechnology-based drug develop-ment. It has offered the algorithm of thepatent researches, which takes into account thesearchin patentdatabase-sand scientificresources, the use of the InternationalPatent Classification, the European Classification, the United States Patent Classification and specifickeywords, top pharmaceutical company namesin the nanotechnology field. It has found out active patenting of nanoparticles as the pharmacologically active substances and their technolo-gies, nanoparticles for drug delivery. It has established that nanotechnology has used for the drug developments of most pharmaceutical groups. Studies suggest perspective and advantage use of nanotechnology in the drug development in the form of nanoparticles, as well as nanocontainers with high pharmacological activity, bioavaila-bility and safety.
