TiVo's stock price is dependent on the actions of stock pickers.
TiVo is being sued and TiVo is suing. I don't see the balance being a big factor in TiVo's future. TiVo won't lose the right to make its products, and it won't win big market share or damages from those it's suing. Most likely, they'll all trade IP portfolios and be done with it for the cost of the lawyers.
Meanwhile, the company is fielding major new products over the next several months. And because of that, the stock has been going up consistently for the past several days. The upward bias from that will continue until the products are shipping, and probably until the first reports of revenue and profit are released.
