Drug patents generally provide market exclusivity for a period, often 20 years from the filing date of the patent application [5]. However, various factors can affect the actual duration of market exclusivity, including regulatory review times and patent litigation [5]. For specific patent expiry dates of drugs, resources like DrugPatentWatch.com can provide detailed information [6].
