Doh, I picked one that flew too close to the sun! That doesn’t mean I am incorrect about style not being copyrightable.
Again depends on what is meant by style… Anyway, many Russian works would be considered copyright infringement in other countries. The country however has minimal interest in respecting foreign copyrights. So if that’s your benchmark I can see why you might assume more leeway than actually exists.
Otherwise I would have done the bare minimum of reading the Wikipedia entry on the book. All I did was Google for “Harry Potter knockoff”, saw that the book was on Amazon, and thought that was enough.
Reading the Wikipedia article it is clear that this series took much more than just the idea of a wizardry school and copied verbatim plot elements. It was not the right example to use.
Here’s what I mean by style. Reggae music. How different is one reggae song from another? What about when a reggae musician sells the rights to one song and then write another song in their own style? Are they infringing on the previous work they just sold to a music publisher?
Here’s what happened when John Fogerty was sued for sounding like John Fogerty:

This logic seemed pretty sound to the jury. It only took two hours of deliberation for the jury to determine that the two songs didn’t meet the legal standard of being “substantially similar” that would have constituted copyright infringement. The Fogerty camp let out a collective “huzzah!”
