Answer:
1- "Copyright infringement" is the intelectual property involved in the case.
2- CCS would probably try to allegue "fair use" of the material associated with a "first sale" right to proceed (both very weak arguing considering strong evidence against CCS).
3- Court would probably rule the situation in favor of the demander Deep Topics - although situation looks commonplace -, for reasons as below:
Explanation: What grounds legal appeal to the case is the fact that CCS not only copies (enough infringing, but somehow tolerable depending on the limit), but compiles - from different sources of the same editorial company - and sells these materials: these are aggravating circumstances, for it reveals the "purpose" is simply profit, the "amount" of material copied and distributed vast, causing at least microregional "sale loss/decrease" to the original producer.
Also, it is unsustainable to argue that CCS copying was not "intentional", nor appropriate is to say that it was "first selling" lawfully copies (as dozens were made) neither could it even speculate Deep Topics INC. made a "late claim" violating legal prescriptional deadline. Lasts practically no legal appeal except, maybe, for an off-court settlement on "cease and desist" talk, but seems unprobable once the demander has already filed a suit to claim for its losses (and agreements do not result in any extraordinary financial compensation), leading an observer to believe that Deep Topics would not decline judicialization.
