How can I provide to Google I do not violate any intellectual property?
I had to reject it because of an unauthorized use of copyrighted content.
Remove any content owned by a third party from your app. For exmaple; your app's store listing contains official images of Thor in the Phone Screenshots and Feature Graphics Read through the Unauthorized Use of Copyrighted Content article for more details and examples. Make sure your app is compliant with the Impersonation and Intellectual Property policy and all other policies listed in the Developer Program Policies. Remember that additional enforcement could occur if there are further policy issues with your apps. Sign in to your Developer Console and submit your app.
