Interesting, just came across another patent application for Kevetrin that just went live on USPTO site. It seems it is just a continuation of prior application? Can anyone clarify for me as I started to read through it but get lose in the heavy science.

Here is a link:

Here is a snippet that I think explains it :

This application is a continuation of U.S. patent application Ser. No. 12/780,132 filed May 14, 2010, which claims the benefit of U.S. Provisional Patent Application Ser. No. 61/180,121 filed May 20, 2009, the content of which is incorporated herein by reference.
