Ideas have little value. Technology, traction, and team have value. Look at many of the high-value applications (Instagram, WhatsApp, etc.) and see exactly how far they had to get prior to being interesting to Facebook. Making an assumption you know what the execution plan for an $11 B company may be is a fast way to being ignored. Design the system, file for patents (but do not be delusional about the time, cost, and actual grant - these are years in process and cost hundreds of thousands in many cases - and often get gutted or rejected). Even then, 5% (or even 1%) of a company that has revenues of $11 B is simply a non starter. Patents will not protect you - there are many ways around that, particularly with that kind of capital.
