The Window To File A Compulsory Licensing Petition Closes After How Many Years From Filing?

The Window To File A Compulsory Licensing Petition Closes After How Many Years From Filing?

• A. 3 Years
• B. 5 Years
• C. 4 Years
• D. 6 Years

Answer: (C)

This question tests the timing window for bringing a compulsory licensing petition. Compulsory licensing exists to balance rewarding invention with public access, but most laws impose a clear deadline to prevent endless challenges. In this framework, the petition must be filed within four years from the filing date; after that four-year window, the petition isn’t entertained under that provision. That four-year limit provides a predictable, finite period for applicants while still giving patent holders a reasonable exclusive term. The other timeframes don’t align with this rule, so four years is the correct cutoff in this context.
