J.R. Simplot Co. has filed a patent infringement suit against McCain Foods USA, Inc. alleging McCain copied Simplot’s twisted potato fries product, Sidewinders®. J.R. Simplot Co. v. McCain Foods USA, Inc., No. 16-0449 (D. Idaho, filed October 7, 2016). Simplot asserts that its patent, “Spiral Potato Piece,” covers the ornamental features of Sidewinders®, including its “inherently distinctive and nonfunctional” shape, and that side-by-side comparisons indicate “McCain copied Simplot’s patented Sidewinders® design in developing its Twisted Potato products.”

Simplot alleges patent and trade dress infringement and seeks damages, an injunction and attorney’s fees.
