The patent period for a drug begins upon the original filing of the patent application. This is a crucial aspect of pharmaceutical development because it protects the intellectual property of the drug during the research and development phase. The patent provides exclusive rights to the developer to manufacture, use, and sell the drug without competition for a certain number of years, typically 20 years from the date of filing.

This period is essential for pharmaceutical companies to recover the significant investments they make in research and development, which can include the costs of failed trials and lengthy development processes. Although the drug may not be available on the market immediately after the filing, the protection starts from that moment, allowing the company to secure its invention while it works through the necessary regulatory processes.

The other options reference milestones in the drug development lifecycle that occur after the patent filing, such as FDA approval or market release, but those do not affect the commencement of the patent period itself.
