Ex, you are absolutely correct, that the patent filed, has a priority date and filing date "before" Ramon decides to work with Peregrine Pharmaceuticals on a full time basis, though one must dig just a tad bit deeper.... to realize what happened.
Actually, this is a nice beginners version of puzzle solving and at the same time, it really makes one ask the question why one would try to diffuse the following facts and here is my quick summary:
1) Ramon Valencia was studying to become a Patent Agent as he begain working with Burstein Technologies as a Scientist in Dec of 1999.
2) Ramon was handed responsibility to work with Peregrine Pharmaceuticals during employment at Burstein and Peregrine liked what they say, obviously... because what does a company do after completion of all the paperwork, interviews..etc to examine prior art..etc by Ramon ... and after priority date submitted on Sept 3, 2003 and filing date finally submitted on Sept 2, 2004
3) So what does a company do...I'll tell what a company does... they hire them and bring them on board for obvious reasons. So yes, the final date to key in on is the hiring date at Peregrine, which shows Jan of 2004 (just a few months after the filing date of Sept 2, 2004)
Now think about it, there is NO WAY that the Ramon Valencia patent does not pertain to Peregrine, but Ex, you are still correct: in that the patent I'm talking about goes back to BEFORE Peregrine hired Ramon.
So digging deeper... Ramon passes Patent Agent exam in 2002 and officially makes use of it in 2003, just as Ramon takes "Effective Negotiations" in 2015 and may also make very good use of it immediately re: Dr. Jedd Wolchok..etc and maybe, those are all just little stepping stones to a much BIGGER deal that one would also try and diffuse.
... and for an added Friday night bonus: Ramon Valencia recommends Taylor Schreiber for Immunology, Molecular Biology, Cancer..etc...etc...and etc... all just pieces to the much bigger puzzle but have touched on this before.. with Rahul(the PS Targeting pro analyst that jumps on BOD of Pelican...) Taylor Schreiber, Josiah Hornblower...
