Apparently the United States Supreme Court might agree with Slashdotters in an appropriate case. In a decision handed down yesterday, Wal-Mart Stores, Inc. v. Samara Brothers, Inc., the Court held that product design, like color, cannot be inherently distinctive and obtain trademark-like protections, until it has acquired distinctiveness such that the marketplace naturally perceives the design to be a designation of product source, such as in the way that "International Business Machines" is associated with products from a company in Armonk rather than a general description for typewriters sold internationally. Thus, absent a design patent, it has just become substantially tougher to obtain protections for industrial designs. Time will tell how important this decision will be."
