It also owns multiple trademarks incorporating the word “purple” as applied to various goods.  These trademarks are registered with the US Trademark Office Purple was chosen for its association with royalty.  (Historically, purple dye was so expensive to produce that it was used only by royalty.)  Royal Purple’s purple-identified lubricant products are sold in over 20,000 retailers in the United States and Royal Purple claims a strong secondary meaning and substantial goodwill in its trademark as a result of this use.

Liqui Moly GmbH Logo.JPGLiqui Moly sells Liqui Moly and Lubra Moly brand motor oil, both of which have packaging that is supposedly purple prior to sale.  Royal Purple alleges that Liqui Moly’s use of the color purple in conjunction with the sale of motor oil is likely confuse consumers.   According to Liqui Moly’s website, its products are sold in a variety of different containers:


Moly2.JPGRoyal Purple also alleges that Liqui Moly’s use is a purposeful attempt to trade upon Royal Purple’s trademark and that Liqui Moly’s use will dilute the “distinctive quality” Royal Purple’s trademarks.  Finally, it alleges that Liqui Moly’s use removes from Royal Purple its ability to control the quality of products and services provided under Royal Purple’s trademark, by placing them partially under the control of Liqui Moly, an unrelated third party.

The federal claims include trademark infringement, unfair competition and dilution under the Lanham Act; Royal Purple has also alleged dilution, trademark infringement, unfair competition and unjust enrichment under Indiana common law.  Royal Purple seeks a preliminary and permanent injunction, the destruction of all allegedly infringing inventory, treble damages, costs and attorneys’ fees.

Practice Tip: Color can serve as a useful identifier of the source of goods to consumers.  The courts, however, have had to draw some narrow lines to balance the various interests.  On the one hand, companies often invest significant amounts of money in promoting their brands and color is frequently a component of that promotion.  On the other hand, there are a limited number of colors – and an even more limited number of colors that are pleasing and appropriate for any given type of product – and courts are wary of providing a monopoly on any given color to any one company.  After all, if such a monopoly is first provided to one company, all too soon the entire spectrum may be spoken for.

This case has been assigned to The Honorable Judge Sarah Evans Barker and Magistrate Judge Mark J. Dinsmore in the Southern District of Indiana, and assigned Case No. 1:13-cv-0492-SEB-MJD.
