From the point of view of the law, how to properly organize the placement of advertising in your application?

Question

Law in IT

I have created a mobile application for mass use within the city. The application already has a very solid audience. At the moment, in-app advertising is based on Google AdMob, but I would like to start advertising myself from local advertisers.
1. What form of ownership of a legal entity is worth having? OOO?
2. What type of activity to choose in OKVED2? 73.11? Position yourself as an advertising agency?
3. To conclude an agreement with an advertiser, do I need to have a patent for the application code in Rospatent? In general, how to properly write a contract? Do I need any special documents or confirmation of ownership of the software product so that the advertiser can easily conclude an agreement on advertising placement?

Answer 1

1. at least an individual entrepreneur, but it will be less desirable for contractors
2. it’s more for you, it’s better when it matches the real one, but something with the web and programming is also possible
3. think about how intermediaries work, who then buy ads from you, why do they need code in Rospatent?
