Back in June, Adidas sued Wal-Mart for selling shoes that were similar in design to their own copyrighted shoes. They had sued Wal-Mart before over the same issue. Wal-Mart settled with Adidas instead of letting it go to court, but we haven't heard how much they gave the shoe company. Now Nike is suing for, essentially, the same thing. It is pretty clear that Wal-Mart is continuing their tactic of taking popular products, having them manufactured incredibly cheaply, and undercutting the original product by selling the knockoff for cheaper. Only this time companies are pushing back.

Nike sues Wal-Mart, alleges patent infringement

NEW YORK, Oct 16 (Reuters) - Nike Inc has sued Wal-Mart Stores Inc, saying the world's largest retailer is selling athletic shoes that infringe on its design patents.

In a complaint filed on Monday, Nike claims Wal-Mart is selling shoes that infringe on its Shox line, which is designed with what looks like springs in the heels.

"Wal-Mart knowingly and intentionally sold and continues to sell the infringing Shoes as simulations of Nike shoes," the Nike complaint states.

Nike is seeking an order to bar Wal-Mart from selling items that infringe on its patents and "damages adequate to compensate Nike for the patent infringement that has occurred."

Wal-Mart could not be reached for an immediate comment.

The complaint was filed in the U.S. District Court for the Northern District of Illinois, Eastern Division.
