Intellectual property rights have become the commanding heights in the context of economic globalization. It can enable enterprises to obtain excess profits and has become the focus of competition among enterprises and even countries. IBM's total profit for the year was US$8.1 billion, and patent transfer revenue alone was US$1.7 billion. This means that the money IBM makes from selling patents in one year is equivalent to more than two years of fiscal revenue in Xi'an. Qualcomm, headquartered in San Diego, USA, has more than 1,400 mobile communication CDMA patents inlaid on the wall at its entrance. With these patents, Qualcomm has transformed from a manufacturing company into an intellectual property store. Nowadays, the role of intellectual property barriers in occupying and protecting the market is constantly emerging, and is becoming one of the dominant forms of non-tariff barriers. At the same time, it is also a new means and a weapon to solve international economic relations. We have entered an era in which we rely on intellectual property rights to participate in international competition. The first is the DVD incident. In the early 1990s, my country's Wanyan Company successfully developed the VCD, a video playback device that uses digital compression technology. However, because the company did not pay attention to the protection of this technology, that is, intellectual property rights, almost overnight, people from all over the country have begun to produce VCDs, and foreign companies have developed higher-definition DVDs based on this and applied for patents to protect them. Now the six major DVD technology developers, Hitachi, Panasonic, Mitsubishi Electric, Time Warner, Toshiba, and JVC, have formed an alliance, known as 6C, to attack about 100 Chinese DVD manufacturers that have not paid patent licensing fees and demand high royalties. Previously, another DVD technology patent alliance, 3C (an alliance formed by three major technology developers, Philips, Sony, and Pioneer), has used customs in the EU to seize DVD products exported from China that have not paid patent taxes on a large scale. Although a notice was issued as early as June 1999, requiring manufacturers to purchase the right to use patents, domestic companies at that time lacked awareness of intellectual property rights and did not pay sufficient attention. China had just joined the WTO, and the other side took decisive actions to withhold goods, catching these manufacturers off guard. Not long ago, our country just reached an agreement with them, paying 5 US dollars to 6C and 4 US dollars to 3C for each DVD sold. The annual output of DVDs in our country exceeds 10 million units, which means that Chinese companies have to pay nearly 1 billion yuan to foreign companies every year for DVD products alone. ?
