Heightening the tension is Apple's response to these copyright violations. The Cupertino company says it does not have the resources to scan every app submission for copyright violations. Its current policy is to remove the app when a copyright violation is reported. This apparently is not sufficient for the Japanese publishers who claim this is "a wholly unconvincing explanation."
This dispute is reminiscent of the ongoing legal between YouTube and Viacom over copyrighted material that appears on the popular video website. From the start, Viacom has pushed YouTube to improve its pre-approval screening process to detect and filter out copyrighted material before it is published.
As the iPad and the iPhone continue to gain in popularity, look for this App Store copyright problem to continue. Right now the Japanese publishers are willing to talk, but other publishers may not be so amicable in the future. Let's hope Apple can work out any kinks before it's forced to duke it out in court.
