Obviously, a writing coach sees a lot of products. In order to protect the coach, it is necessary that the client waives in advance any possible copyright infringement claim or claim of theft of ideas, trademarks, service marks, images, etc. If such an infringement event occurred- and it would only be by accident; obviously the material would be withdrawn from public view by the Coach. This does not apply to material protected by the fair usage doctrine of copyright law. Also, it is best if longer material is being developed- that the user procures effective government copyright in advance- for the purpose of general protection against infringement. This also does not apply to collaborative projects described in a contract or agreement or by joint copyright.
