A patent's expiry date may change depending upon legal activities going on that patent. Critical
activities like
abandoning of a patent, term extension of a patent or amendment of its claims can increase or decrease
the life of a
patent hence affecting its expiry date and in turn affecting the generic launch date of that drug.
Tracking these
ongoing activities on a patent application helps to keep an eye on the latest developments in the
patent process of
the drug which can give an idea of how early a drug's generic could be available. The next section
provides a list of
recent legal activities on Vosevi's patents.

Several oppositions have been filed on Vosevi's European patents.
EP oppositions
can significantly impact the timeline for the generic launch of drugs. If an opposition results in the
revocation or
amendment of a patent, it can shorten the exclusivity period of the original drug. This can lead to an
earlier entry
of generic versions into the market. To help you estimate the potential early arrival of Vosevi's generic, the next section provides detailed information on
ongoing and past
EP oppositions related to Vosevi patents.
