In 1999 the Lanham Act was amended in two ways regarding functionality. First,
functionality was added as a basis for canceling incontestable registrations. Second, the statute was amended to clarify that the plaintiff has the burden to prove that an unregistered trade dress is nonfunctional. The Lanham Act was clarified to provide that functional matter is not registrable.All registrations, including those that are incontestable or over five years old, can be cancelled on the ground that the mark is functional.
Here is what the U.S. Supreme Court said in TrafFix Devices, Inc. v. Marketing Displays, Inc
"A prior patent, we conclude, has vital significance in resolving the trade dress claim. A utility patent is strong evidence that the features therein claimed are functional. If trade dress protection is sought for those features the strong evidence of functionality based on the previous patent adds great weight to the statutory presumption that features are deemed functional until proved otherwise by the party seeking trade dress protection. Where the expired patent claimed the features in question,
one who seeks to establish trade dress protection must carry the heavy burden of showing that the feature is not functional, for instance by showing that it is merely an ornamental, incidental, or arbitrary aspect of the device"
The court has also held that a patented product design is strongly presumed to be functional, and indicated that a design may be deemed functional even where alternative designs exist and there is no competitive need for the claimed feature.
On October 30, 1999, the Trademark Law Treaty Implementation Act (TLTIA) became effective in the United States. One of the things this act did was clarify The Lanham Act to provide that functional matter is not registrable. The law also amends Section 43(a) of the Lanham Act to clarify that the plaintiff has the burden to prove that an unregistered trade dress is nonfunctional.
Another Supreme Court Case was Qualitex Co. v. Jacobson Products Co.
The Court held that the mere color of a product alone can be protected as a trademark, provided that it has acquired secondary meaning and is not functional

Look guys, we can go on and on about this, but I believe the evidence shows that function things cannot be trademarked. It seems that the fact that it was originally patented says that it is indeed functional. I believe the evidence also shows that even if the "mark" has gained secondary meaning, its functionality renders it inelligible for trademark protection.
Looking for more opinions here, am I reading this wrong?
