Legal analysis: Whether the unmarked r can be determined to be a trademark infringement depends on the specific circumstances. If the trademark name after combining two or three trademarks is used without the circle R, whether it infringes upon the rights of the prior trademark depends on the similarity between the combined trademark and the prior trademark. If there is a large similarity, then even if you do not mark the circle R, it will still infringe the prior trademark rights. If the rights holder pursues the case, you will bear the corresponding consequences of the infringement.
