Our Trade Dress

The Hammer-Schlagen® Stump

Hammer-Schlagen® engages in commerce under a specific configuration of shapes, designs, and materials that compose a specific visual appearance. Our trade dress[1], which gives rise to the elements found in our logo[2], is commonly referred to as the "Stump." Officially, the Stump is described as a three-dimensional trademark comprised of a cylindrical cross-section of a tree with nails positioned around the outer circumference of its upward facing flat circular surface and a cross-peen hammer[3]. Generally, the Hammer-Schlagen® Stump uses 16d common bright nails with a 3-pound hammer and plains cottonwood (which is Minnesota's largest diameter tree[4]). Note, however, that our Stump need not encompass these exact elements; anything confusingly similar may also be considered our trade dress. Beginning in the in the 20th century, our widespread use of this distinctive decor created an environment that generated recognition in the eye of the public to immediately affiliate our Stump with Hammer-Schlagen® and our other trademarks.
