The highest court the case would likely reach is the BGH. The EU courts aren't really courts of appeals, but concern the interpretation of EU directives etc. If there was an unclear EU directive in this case, the LG should have sent the case straight to the EuGH. Nevertheless even the decision of the LG itself isn't final, but it concerns a "preliminary injunction". However in cases like these, it is unlikely the end result would be different.
