The patent expires in 2017. You don't have all that long to wait.
2018 in the U.S.
The patent for Tysabri (natalizumab) was initially set to expire in 2019, but additional patents related to the drug have been filed and granted, potentially extending its exclusivity. The exact expiration date can vary based on these additional patents and any ongoing litigation. For the most accurate and up-to-date information, checking the latest patent filings or announcements from the manufacturer, Biogen, would be advisable.
Yes. There is a final date on which patent rights eventually do expire, but you will have to do your own research on the patent in question.
