29. Any party, which intends to launch CTPR post the expiry of the product/process patent, would be forced to examine this complex maze of patents and patent applications, even after the product and the process claimed in IN‟332 has fallen in public domain.

30. Admittedly, the Markush patent and both the product and process patents relating to CTPR have expired in August 2022 and there can be no exclusivity in the same. However, if one goes by the list of granted and pending patents applications, the various components, intermediates and manufacturing processes of CTPR, if granted/validated, would result in the Plaintiffs monopoly and exclusive rights till 2041 i.e., a further period of 19 years.
