RetroPie has been trademarked in the USA by a 3rd party. They are using the trademark to issue take down requests to retailers, including those who are just selling hardware listed as “compatible with RetroPie”. Meanwhile they are selling RetroPie via their website and Ebay.
There is a risk that this person may try and use the trademark against us too.
We would like to challenge the trademark – It was filed after we were using the name, and they are using it to associate themselves with our software.
If you are an attorney or think you could help – please drop us an email at retropieproject [at] gmail.com.
