the risks and uncertainties associated with the litigation with TPL which may negatively impact the ability to generate revenues from future licensing transactions.

I guess it would depend on when this was written, but because it states future licensing I would be more inclined to believe that the litigation with TPL is still on. I would think if the litigation was settled it would also be a PR event and we would know. Because the statement above is in the PR I would bet the Litigation with TPL is still going on.
