If it is just a service concept, then the intellectual activity rules and methods stipulated in Article 25, paragraph 1, item 2 of the Patent Law are not the subject of authorization and no patent right can be granted.
However, if this method is combined with corresponding equipment (such as servers, networks, etc.) to form a technical solution, it is an authorized object.
For example, a three-way chess rule/method is not an authorization object; however, a three-way chess game that uses this rule is an authorization object.
To put it bluntly, this is largely a word game.
