The “Quilted Diamond Design” of toilet paper made by Georgia-Pacific is functional and therefore cannot be protected as a registered trademark under federal law. Georgia-Pacific Consumer Products L.P. v. Kimberly-Clark Corp., 7th Cir., No. 10-3519, 7/28/11.
In short: Defendant Kimberly-Clark was entitled to summary judgment on Georgia-Pacific’s trademark and unfair competition claims because the asserted product configuration trademarks reflected functional product features, and were therefore invalid.
