Publici Juris Law and Legal Definition

Publici juris means a right of a public. When a right belongs to the public it is called publici juris. Publici juris refers to common resources. For example, roads and bridges regulated by a state for general public benefit relates to publici juris. States can grant franchise to private parties to maintain such general resources. However, these grants remain under state supervision to preserve public right access.

Now, publici juris is used in intellectual property rights cases. In some cases patent rights are not granted to certain invention on the basis of publici juris. This means that there was no novelty in the invention and it had always belonged to the public.
