Hey @BillyJF, if you think that the material that you are using might be infringing upon somebody else's idea or content, we would suggest not including it in your course. The easiest way to check whether it is ok for you to use somebody else's content in your course is to contact them directly and ask for their permission. You can always reach out to firstname.lastname@example.org for more information.
Hope this helps!
