i saw what you said, i believe what you are saying, but I'm talking about something different: if you independently with no knowledge of other logos, inadvertently, purely by chance, recreate an already existing logo, the person who deploys this logo is liable for trademark and/or copyright infringement.

I'm asking "when does the trademark and copyright search take place, who does it, if it uncovers that your work is not what a court would consider to be "original/unique", then what happens?" I'm expecting you would accept liability, but are you even aware this issue exists? are you at a bare minimum offering a do-over?

it's a mistake to deploy a new logo with no consideration of the intellectual property issues. sure, if you're small, you'll get a cease and desist and you'll switch to a new one. but if you achieve any type of success and are then sued, it's a major headache to deal with.
