The LexCampus Weekly Newsletter No. 12

24th March, 2021

Hi,

This week we look at a judgement by the Delhi HC where it disposed of an application for injunction filed by Astrazeneca, Inc. The HC held that at the stage of preliminary injunction it is not necessary for the Defendants to conclusively prove invalidity of patent, establishment of a prima facie case is sufficient. This week our patent blogpost discusses the relevance of a lawyer in the realm of patent administration and the areas where lawyers can shine within the same. We offer tips on drafting the transition clause in a patent and conclude with a patent related FAQ answered by Prof. Feroz Ali.

DRAFTING A PATENT – TRANSITION CLAUSE
