At present, there are 25960 patents related to NFC technology in the world. It was originally a short-range wireless communication technology promoted by Philips, Nokia and Sony. Related patent applications in this field are mainly held by a few large companies that participated in the initial development and standard formulation of NFC. Although the number of patent applications at the beginning was small, they included a large number of basic patents and important patents, which contained high gold content. The defined NFC open technical standard makes it impossible for future generations to bypass its technical threshold. Since then, the number of patent applications in the NFC field has been increasing. During this period, holders of NFC basic patents began to conduct extensive patent layouts in various countries and strive to maintain patent advantages. For example, NXP applied for two basic NFC technology patent applications in China and based on these two patent applications, it is impossible to bypass mobile terminals and card readers based on NFC technology.
At present, the number of patent applications in the NFC field is increasing rapidly. On the China Patent Publication website, relevant NFC patent applications are updated almost every day, and there are currently at least 5,150 patents that have been passed. During this period, mobile payments developed rapidly in various countries. Near-field mobile payment is favored by enterprises because of its security and speed. NFC is recognized as the main communication standard for short-distance mobile payment, and the standard is gradually unified. Major communication companies such as Google, Samsung, Apple, and Apple have successively launched near-field mobile payment solutions based on NFC technology, which has driven the industry to increase the research and development of NFC technology, and the number of patent applications has also greatly increased. The development of mobile payment services has led to the development of NFC technology, as well as the rapid development of NFC in other fields, such as data transmission and electronic tickets.
In the global ranking of patent applications in the NFC field, the top 20 applicants in the number of applications are all companies. Mainly dominated by foreign companies. As the leader of NFC technology, Sony, Nokia, NXP, Qualcomm and Samsung have a large number of basic patents and have patent layouts in various countries. Taking China, the United States, Europe, Japan and South Korea as the scope of analysis, at least 65% of the patents of Sony, NXP and Qualcomm are located in the above three countries or regions at the same time. Samsung's NFC technology has the most patent applications worldwide, and the technology has a relatively good degree of commercialization.
The NFC chip designed and produced by NXP has become industry-wide China's NFC technology mainly started from the rise of mobile payment applications, so it started late, domestic companies have fewer basic patents, and the patent layout is obviously weak. ZTE is the leading company in NFC patents among domestic companies, and domestic companies have the largest number of patent applications. It also has a specific patent layout around core technologies, but its layout is significantly weaker than that of large companies such as Samsung and Sony. As a major domestic NFC application country, it also has a broad mobile payment commercial application market, which provides superior conditions for the development of NFC technology. However, my country's current near-field mobile payment market is still dominated by QR code payments, and NFC technology only has advantages in limited areas such as bus cards. It can be said that the industrial applicability of my country's NFC technology is not yet mature, which presents both a challenge and an opportunity for domestic NFC companies.
In recent years, the number of patent applications for NFC technology in my country has increased rapidly, but most of them are scattered, and the depth and system of technology research and development are insufficient. Related companies should strengthen in-depth and systematic research and development, and strengthen the layout of existing patents and peripheral patents. At the same time, as more and more domestic telecommunications companies move to overseas markets, their understanding of global patent layout must also improve.
