Porta Est Nascetur Proin: Understanding U.S. Intellectual Property Law

The concept of 'porta est nasciturus' is a Latin phrase that translates to "there comes into being by way of the mother". In the context of U.S. Intellectual Property Law, this phrase has significant implications for patents and copyrights.

At its core, the doctrine of "nascetur propter partem" (or "nasciturus") refers to a parent-child relationship between an invention or literary work and its author. This principle is rooted in U.S. law and has been interpreted through various court decisions.

Case Law Interpretations

In the landmark case of KSR v. Teva Pharmaceutical Industries, Inc., 550 U.S. 427 (2007), the Supreme Court clarified the scope of the "nasciturus" doctrine by establishing that it only applies to parent-child relationships between an invention or literary work and its author.

This decision marked a significant shift in the interpretation of the "nasciturus" principle, as it has far-reaching implications for the protection of intellectual property rights.

International Comparison

The concept of " porta est nasciturus" is not unique to U.S. law and can be found in various international patent and copyright agreements, such as the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS). However, the application of this principle varies significantly between countries.

For example, in Canada, the "nasciturus" doctrine is not recognized at all, while in some European Union member states, it is used to protect certain types of inventions.
