Patent prospecting in advanced wound healing technologies: an overview of the innovation landscape for wound treatment

Dressings are essential medical devices in the treatment of wounds. The great diversity of skin lesions has led to the development of different therapeutic approaches involved in optimizing re-epithelialization. Advances in the field's technologies have led to an increase in therapeutic patents with various applications, including complex lesions that are difficult to heal. This article presents an analysis of patents and scientific publications on the development of innovative dressings for the treatment of complex dermal lesions, using Derwent World Patents Index (DWPI) database. The study provides an overview of materials, drugs, and nanotechnologies used in dressings, as well as their applications. Finally, the patent analysis enabled a comprehensive examination of trends, places of protection, market dynamics, and technological domains, providing valuable information on the advances and therapeutic potential of dressings. The development of new technologies associated with wound dressings applied to the treatment of injuries demonstrates the expressive interest of the scientific community, indicating advances in the sector. The incorporation and combination of diverse technologies employed in currently developed and investigational dressings demonstrate the emergence of increasingly efficient products, enhancing accessibility to therapies and contributing to the population's quality of life.
