"Any fool can read an 8K and memorize its contents."
But apparently not every fool can read an 8K with comprehension.
I agree with you on one thing you say here: there are those who do not believe in RXPC's prospects, and will use the void of news as a means of casting doubt on the merger rumor. I'll go further: I think the void of news means the company is not doing ANYTHING. The patent expiration in two months means they can't sell any more license agreements, IMO, so there is nothing for this company TO do.
The lack of public information certainly does not prove, or even suggest, that someone is secretly trying to take over the company!
