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 Krazati's patents.

delaying the generic
launch. Given below are details of the exclusivities granted to
Krazati.

Clinical Trials
Recent Clinical Trials on Krazati:
Sometimes companies keep conducting clinical trials even after the drug's approval to discover new formulations, methods of use, or new treatment indications, so they could file for additional patents or receive regulatory exclusivity extensions, such as pediatric exclusivity, potentially delaying generic competition.

These strategic moves by the drug owner might delay generic substitution or lead to additional sales of the brand drug, even after patent expiry.
