they (patents) maybe worth a Billion or toilet paper.... no one knows yet but for you to say they aren't worth the cost is simply foolish....
"foolish" is an understatement! I would say mindless (business 101).
Aside from the absolutely obvious, that patents are necessary, utterly indispensable, and without patents, there is no company!!!! I would say it's still very useful, as a way of assessing the intellectual property as a metric of the achievements in the science arena.
If the patents are granted, it's one more indication that PSTI is onto something original and intellectually defensible as an invention and/or discovery by the company.
