No lawsuit, because everything was out there.
You're likely correct that the low market cap would discourage most of the law firms that start these class action stock-related lawsuits from issuing their usual slew of PRs after something like this, but there's another issue that would prevent them from initiating action.
COIN's balance sheet basically implied bankruptcy for nearly a year now, and they've been surviving on convertible debt.
Any shareholder who looked at the filings would know this, and any investor would have likely exited sometime in 2012.
Those who were left were speculators making money on swing trades, and likely knew that one day, the ride would end. They'll take their losses in stride.
This deal with Finjan avoided BK, which would have instantly driven the share price to zero, and folks who bought shares in January still own shares with a value a little higher than what they paid. Those who bought in Feb through March and have held will be losers, but again, they still have a small amount of value left.
Even those people will have opportunities to sell at a price above $0.50 until Finjan files its next 10-Q, which will show the number of outstanding shares at 268M. When that happens, the financial websites like Yahoo Finance, the OTCBB and OTCMarkets, which now show only the roughly 1M post-reverse shares (because they show the number shown in the 10-Qs and 10-Ks,) will update the OS to reflect what most of us here now know, and unless Finjan shows some dramatic revenue and income increases, the reality of 268M shares will tank the price.
Because COIND was disclosing its problems and likely inability to continue operations for quite awhile now, there's nobody willing to go to the expense of a lawsuit.
