<< Ligand has 200 issued patents >>

The FDA couldn't possibly know all of the complexities when it comes to the science behind all of the new drugs, especially those that are breaking new scientific ground.

Let's assume, for discussion sake, that the science behind Sparta's Retinoid patent overlaps some of Ligand's patents (I assume that this happens occasionally). Does the one holding the first patent win the patent rights, or does it get more complex than that?

In other words, using your comparison between Ligand's many Retinoid patents, and Sparta's one patent: How comfortable can Sparta be about their patent being upheld in the future?

Thanks, Bob
