I have an idea for a social network site. I know Facebook has many patents and I'm afraid of violating one of some of them. I'm not located in the US, main questions:
Do you think I should talk with a lawyer and ask him to check the patent of Facebook and other companies before I start to work on the idea? I think that to do that I'll need a few thousand dollars and this is something I don't have now. What I really want is to start working on the idea and then receive funding and then pay for things like a lawyer and patent.
Will a lawyer in my country be enough to check patents in the US?
Thanks!
