Your question is lacking a lot of additional detail that would make it easier to make a suggestion.

My first question is, why do you think you're going to just "walk in" to a job at these companies? It would seem that if you can just get a job at the companies you listed you should also have sufficient connections to raise some money for your startup on agreeable terms.

So, I'm not sure that your options as listed are realistic.

Regarding any patent you've filed on work that you've already done, these should be no issue to any new employer. You would want to ensure they are aware of this beforehand to make sure any patent-grant clauses in an employment agreement have proper exceptions, just to eliminate potential future confusion.
