HP sues ink refillers

News.com reports on the HP lawsuits against Rhinotek and InkCycle. Looks like now HP is just using it's patent arsenal to force refillers to list their cartridges as "used" and "refilled" - which only seems fair, as it allows consumers to make an educated comparison. I just hope it's not foreshadowing of bigger and more sinister things to come, as HP holds 4,000 patents related consumable supplies such as ink and cartridges.
