Questão jurídica principal
Whether the Obergericht violated the right to be heard by not addressing all arguments in detail.
Decisão extraída
The reasoning was sufficient because the decisive considerations were identifiable and the defendant could challenge the judgment effectively.
Fundamentação extraída
A court need not address every submission individually; it may focus on the decisive points. The appellate judgment clearly showed why third-party authorship was rejected and why authorship by the defendant was accepted.
