In the technical arena, we routinely deal with trademarks and their validity. A basic tenet of
trademark law is that if the thing that is being trademarked is "functional", i.e. useful for the product to function, it can not be the subject of a trademark. We recently wrote about a case with which we disagreed that found that the image of Betty Boop on a purse was functional and therefore could be used on the purse without infringing.
Another case involving functionality in a trademark setting was recently decided by the Seventh Circuit and this case involved toilet paper. The initial line in Georgia-Pacific Consumer Products LP v. Kimberly-Clark Corporation et al (Seventh Circuit Court of Appeals, No. 10-3519, Decided July 28, 2011) states: "Toilet paper. This case is about toilet paper. Are there many other things most people use every day but think very little about? We doubt it."
The case is a decision on a summary judgment motion filed by Kimberly-Clark that, inter alia, alleged that the "Quilted Diamond Design" on Georgia-Pacific's Quilted Northern was functional and therefore, Georgia-Pacific couldn't enforce an infringement action against Kimberly-Clark using a similar design on their Cottonelle product, even though the quilted design was the subject of a registered trademark.
The decision rested in large part on the fact that Georgia-Pacific had several utility patents on the design and the Court found that this was "strong evidence" that the design was functional, particularly if the "central advance" claimed in the utility patent matches the "essential feature" of the trademark.
The Court also engaged in what passes for ribald humor in an opinion. In addition to their explosive first line described above, the puns flowed freely in the opinion: e.g. "Georgia-Pacific unrolled this suit against Kimberly-Clark", "...despite the fact that the judge dutifully plied her opinion, we now wipe the slate clean...", "[this] claim...does not hold water" and the "...judge was spot-on". Riotous humor for a judicial opinion.
In the end [see what I did with that?] the Court held that "...if a design is functional the owner cannot trademark the design and block innovation. Georgia-Pacific, whether intentionally or not, patented their Quilted Diamond Design and claimed it to be functional. They must now live with that choice and can benefit only under the protection of a patent, not that of a trademark."
So the Court got to the bottom of the matter, flushed Georgia-Pacific's trademark claim and dispensed a double roll of justice.
Please, may I be excused for this?
