I also dont think I have to prove anything to the company, they should be the ones to prove they are fake if they are accusing it.
well, this gets into semantics. If they sue you, they would be able to require you to submit the product for their review and authentication. So, bottom line, do you have the funds or the legal acumen to be able to even respond to a suit? If not, it might be in your best interest to do what it takes to prove the items are authentic.

So if I buy a item directly from them I can sell it but if I get it from someone else that bought it from them I cant, even if they are the exact same item?
it would depend, ultimately, how they were originally obtained.

but they arent saying they are fake now anyway.
Oh, so now the story changes. This is from your first post:

It got pulled because the makers of the item said it was a fake,
They cant claim they are fakes cause they tried that before
what? If they want to sue you, they surely can claim they are not authentic.

They refuse to bring court action against me. I listed the items on craigslist, the exact same ad from Ebay and sent the link to their lawyer, its been a week, no court hearing yet.
Oh, that's brilliant; poke the bear to see if he will bite you.

a week? Heck, it will take them more time than that to just get the info assembled and to write a complaint.

They refuse to bring court action against me.
yet. They have time...lot's of time.
