Do you have any experience with patent litigation? It seems not.
Every single named defendant has the right to file reviews with the PTAB and have their chance in ruling a patent that is directly effecting their sustainability as a company null and void. As a matter of fact big tech normally hires 3rd parties that specialize in bringing patents to the cleaners in the PTAB process (see companies like RPX). Even a 3rd party which has no affiliation to the effected party can challenge a patent in the PTAB process.
With that being said, it is near an obligation for named defendants to challenge the patent to at least have a mere shot at invalidating claims, or if anything delay the case against them.
This is very standard in this process. The good thing here is that they have already been through the PTAB process and the initial precedent set through rulings almost always prevail.
Good luck on the continued effort to grab cheap shares.
Really should cover any opened position. The downward of the dubya (W) will be complete when NLST gets pushed down..... then the Gee Dubya ensues. Could be back up to $3..... just a guess at what may be.
DTCC rules coming very soon. Daily reporting instead of monthly or bi-monthly reporting. Payment must be made when payment demanded.... within on hour. I'd take the loss and cover..... but if you must.... be stubborn.
