COVID-19: Impact on the world of patents

Many IP offices around the world have adopted measures in response to the COVID-19 pandemic. For example:

PACTE LAW: New opposition procedure in France

Under the PACTE law, a new opposition procedure came into force on 1 April 2020 in France. Here is a brief overview of this new procedure, which is fairly similar to the European procedure.

Purpose and interest
