Question

Law in IT

I am an ordinary individual. I want to buy a program on iOS, how to make a purchase so that only I have all the rights and in the future, a year later, the person who wrote this software could not resell it to other people or publish the source code. The owner of the software is also an individual, we are located on different continents. Is it possible to fix all this legally? The cost of the application is not a small amount, so you want to legally secure yourself.

Answer 1

No, because ALL rights to the software cannot be transferred. The contract according to which you obtain the right of authorship will be declared null and void in any court, since the right of authorship is inalienable and non-transferable. In general, you to lawyers.
