We consider each of these patents to be of value and aggressively protect our rights throughout the world against infringement. Because we are involved with many product lines, the loss or expiration of any particular patent would not materially affect our sales and profits. We own or have licensed numerous trademarks which are registered in many countries, enabling us to market our products worldwide. Our Spicer, Victor Reinz, Wix, Clevite, Glacier and Vandervell trademarks, among others, are widely recognized in their respective industries. 6 http://www.sec.gov/Archives/edgar/data/26780/000095015204001384/105571ael0vk.htm 8/1/2004
