Czech Small Arms protects its products and related innovations in a variety of ways including, without limitation, patent, trademark, and copyright protection throughout the world. To comply with the marking requirements especially under U.S. patent law promulgated under 35 U.S.C. § 287, Czech Small Arms has marked all or at least substantially all of its products with the word "patent" located adjacent a uniform resource locator (URL) that directs the public to this particular Web page. U.S. patents claiming subject matter currently owned by Czech Small Arms (or for which Czech Small Arms has one or more licenses) are listed below. Additionally, patent application serial numbers for published U.S. patent applications owned by Czech Small Arms (or for which Czech Small Arms has one or more licenses) that have not issued yet as patents are also listed. Website visitors are reminded that damages can be sought and recovered for infringing activity covered by a claim of a patent retroactively back to at least the publication date of such application under certain circumstances. Therefore, just because a patent may not have issued yet on subject matter claimed in one or more patent applications listed below, unlicensed parties are NOT free from potential patent infringement liability to make, use, sell, offer for sale, and/or import such claimed subject matter. Czech Small Arms and its licensor(s) take infringement of their respective intellectual property rights very seriously and will not hesitate to enforce such rights if necessary.
