We believe that our trademarks, design patents and other proprietary rights are important to our success and our competitive position. We use trademarks on nearly all our products and believe that having distinctive marks that are readily identifiable is an important factor in creating a market for our goods, in identifying us and in distinguishing our goods from the goods of others. We consider our , , , , , Skechers, Skechers Slip-ins, Skechers Hands Free Slip-ins, Skechers Performance™, Skechers GOrun, Skechers GOwalk, Skechers GOgolf, Skechers Viper Court Pro™, Ultra GO, Skechers on-the-GO, Skechers Cali, Skechers Street™, Skechers USA, Skechers Active™, Skechers Sport Active™, Skechers Work™, Skechers Outdoor™, Max Cushioning, Massage Fit, Mark Nason, Skechers Modern Comfort, D'Lites, BOBS, BOBS Sport™, Our Planet Matters, Glide Step, Skech-Air, Skechers Kids™, Twinkle Toes, S Lights, Relaxed Fit, Arch Fit, Hyper Burst, and Air-Cooled Memory Foam trademarks to be among our most valuable assets, and we have registered these trademarks in many countries. In addition, we own many other trademarks that we utilize in marketing our products. We also have a number of design patents and utility patents covering components and features used in various shoes. We believe that our patents and trademarks are sufficient to permit us to carry on our business as presently conducted. While we vigorously protect our trademarks against infringement, we cannot guarantee that we will be able to secure patents or trademark protection for our intellectual property in the future or that protection will be adequate for future products. Further, we have been involved with litigation in the past for patent and trademark infringement and cannot be sure that our activities do not and will not infringe on the intellectual property rights of others. If we are compelled to prosecute infringing parties, defend our intellectual property or defend ourselves from intellectual property claims made by others, we may face significant expenses and liability as well as the diversion of management's attention from our business, which could negatively impact our business or financial condition.
In addition, the laws of foreign countries where we source and distribute our products may not protect intellectual property rights to the same extent as do the laws of the U.S. We cannot be assured that the actions we have taken to establish and protect our trademarks and other intellectual property rights outside the U.S. will be adequate to prevent imitation of our products by others or, if necessary, successfully challenge another party's counterfeit products or products that otherwise infringe on our intellectual property rights on the basis of trademark or patent infringement. Continued sales of counterfeit products could adversely affect our sales and our brand and result in the shift of consumer preference away from our products. We may face significant expenses and liability in connection with the protection of our intellectual property rights outside the U.S., and if we are unable to successfully protect our rights or resolve intellectual property conflicts with others, our business, financial condition, results of operations, and cash flows could be materially and adversely affected.
