Where are the patent wars? Links?

Arcam is the only one that can legally do powder EBM, DDD is using a powder EBM, so the most likely scenario here is that DDD is quietly using at least one Arcam machine. They may not mention Arcam in the patent but that in no way implies DDD has made their own powder EBM.
