In the spirit of openness, we have posted a public patent license for the XMP specification on the XMP Developer Center. In the past we have received many inquires about the patent position on XMP, especially from larger corporations looking to implement the XMP specification.
What this public document provides is an open and free public license to develop and distribute compliant implementations of XMP:
Adobe grants every individual and organization in the world the right, under all Essential Claims that Adobe owns, to make, have made, use, sell, import and distribute Compliant Implementations.
This will further remove barriers to the adoption and use of XMP and a metadata standard across our partner solutions and ecosystems. Which is really exciting because better interoperability results in a better customer experience when media is exchanged across applications and services.
