From your post-

TPL is authorized to act on behalf of the parties pursuant to the Commercialization Agreement and the Grant referred to therein, including, but not limited to, contacting, pursuing litigation against, or entering into discussions or negotiations with potential infringers, entering into license agreements, settlement agreements, or other similar agreements with respect to the MSD Patents,or selling or otherwise transferring any interest in the MSD Patents

Just read the Commercialization Agreement it contains nothing pertaining to TPL or any other entity authorizing a sale of either T-Newco or P-Newco (now PDS).

There may be buyout someday but it won't happen through PDS alone. Corrections welcome.
