I do not read this as PDS is the owner of the MMP patents..

but thru this agreement between TPL/Moore & PTSC, 

PDS has granted TPL the privledge to pursue and license

jmo..  correction welcomed

What do you make of this, please?:

7.3  P-Newco represents and warrants to TPL that:               (a)  It is the sole owner, and for the term of this  Commercialization Agreement will remain the sole owner, of all right, title, and interest in and to those certain rights to the MSD Patents transferred by        Patriot and TPL to P-Newco pursuant to the P-Newco License and T-Newco License;
