What does it mean that a drug was "repatented"?
From the New York Times:
Albuterol, one of the oldest asthma medicines, typically costs $50 to $100 per inhaler in the United States, but it was less than $15 a decade ago, before it was repatented.
I get that it means the patients will have to pay, however, how can you re-patent something? Intuitively, I believed that once the patent expires, it's over. And that you can only patent novel inventions.
