This question appears to be off-topic. The users who voted to close gave this specific reason:

  • "Production and Technology Questions Are Off Topic — Ask Patents is a community-run website to ask about the patent process or to help find Prior Art on US Patents or Applications. Unfortunately, questions about the underlying technology or production of products covered by these patents is outside the scope of this site. Sorry about the confusion." – Matthew Haugen
If this question can be reworded to fit the rules in the help center, please edit the question.

From what I have read elsewhere, the medicine mentioned in the patent didn't really work, and the patent has been abandoned.

It would help if you could include a link to an article where you may have read this. Questions like this are off-topic for the site, but it's still a good general goal to include as much verifiable information as possible in your answer. – Matthew Haugen Sep 9 '15 at 1:44
