Georgia Pacific makes paper towels and paper towel accessories. It's a glamorous life -- especially when you design some spiffy new automatic paper towel dispenser that uses its own proprietary premium paper towels. Of course, premium paper towels come at a premium price, and when that happens, other companies, like von Drehle, rush in to fill the cheap-paper void.
The inevitable result of such competition is litigation. GP accused VD of contributory trademark infringement. Shortly thereafter, they also attempted to enforce their rights against numerous other manufacturers in other venues and jurisdictions. The VD litigation proceeded through summary judgment in their favor, a Fourth Circuit reversal, and a remand before von Drehle sought to amend their answer to reflect preclusion issues.
