The article aims to describe, identify and classify application forms for Open Innovation, delivering specific cases for its justification. The methodology consisted of a critical review of the main theoretical fundamentals presented in the statement about art, the concept of Open Innovation, its evolution and application. The concept of Open Innovation and its implementation is a matter that occurs in practice, where methodologies have not been determined to define the application mechanism that best suits the organization. The document has four sections. The first discusses the evolution of the concept of Open Innovation. The second classifies this concept, then in the third we present specific application fields and its main mechanisms or application tools, application examples and at the end of the last section findings and input on prospective studies are delivered.
