YES. This.

I cannot even begin to describe how many times I've heard commenters here spout advice like they are experts in patent law when they simply don't have the most basic grasp about them. It's terribly frustrating and scary to see people taking this often horribly wrong advice.

Sure, some people here are right, you probably don't have much to fear, they're probably just bullying you, but please, please, please don't take legal advice from a random forum. That's like taking advice on rails development from a forum full of lawyers. They just won't know what they're talking about much of the time and it can be very dangerous.
