| Summary: | The most of the scientific literature shows that the studies on biopolymer-based hydrogels have a bright future. This work, in the form of a patentability study, englobes information present within patents (i.e., patent applications and granted patents) related to biopolymer-based hydrogels. The patentability study describes the state of the art by introducing what has been patented in relation to biopolymer-based hydrogels regarding the preparation methods/process, formulations and applications. A detailed analysis is then given regarding the publication year, international patent classifications, inventors, applicants, owners, and jurisdiction. Furthermore, this work gives a competitive analysis of the past, present, and future trends in the biopolymer-based hydrogels and leads to various recommendations that could help one to plan and innovate a research strategy. The classification of patents reveals that most inventions intended for medicinal preparations characterized by special physical form, as well as materials characterized by their function or physical properties, such as hydrogels or hydrocolloids.
