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.
