As has already been observed, there are many patent lawyers who will act on a contingency basis, so the mention of the preferred shares does not imply they will be issued, in fact, it would have been unusual for them not to have been mentioned as part of standard disclosure.
Even if finance was required, it has to be remembered that PTSC is NOT the company that could only obtain the S&L-type financing of the past.
