So basically you give up an unstated x% ahead of time for access to Google+Intertrust's portfolio. A few thoughts. First, this only provides access to the patent portfolio. It doesn't pay the (considerable) litigation bills. Second, this portfolio is already available. If Alice sues Bob, Bob can negotiate just in time with Intertrust or IBM or ... for access to a defensive/offensive portfolio. This acquisition of patents during litigation is common practice. Third, just as Intertrust is going to do their due diligence on you, you are taking a risk that their portfolio is a good match for your risk. You need to do your due diligence on them and on their portfolio. I might go for this, but it would be at a pretty low percentage, like less than a percent.
