“…In addition to studies on the knowledge structure in the technological system, other studies seek to apply the patent classification co-occurrence network. In this network, nodes represent classification codes, among them the United States Patent Classification (USPC) and the International Patent Classification (IPC) are most commonly used [24], [25]. These nodes are linked by a tie when they occur together in one patent, and the strength of a tie represents the level of coupling [26], [27].…”

Self-driving vehicle (SDV) has become a new driving force in the automotive industry, but no scholars have yet to dig deep into the competitive technology intelligence in the SDV field. Therefore, this study analyzes technology, competition and cooperation from the perspective of global patents, aiming to provide a reference to governments, enterprises and research institutions to grasp the competition situation and timely find the new investment opportunities. In this study, the Derwent Innovation Index (DII) is selected as the data source, the Jaccard index instead of the International Patent Classification (IPC) co-occurrence frequency is used to reflect the technical correlation, Relative Technology Advantage (RTA) index and the International Business Potential (IBP) are used to represent the competition among enterprises, and multiple network indicators, including macro and micro, are used to measure cooperation. The results show that: 1. Vehicle control system is the most critical technology in SDV field; 2. Different types of companies show different competitive advantages. Auto manufacturing companies rely on their strong comprehensive strength to maintain their position, but component suppliers are most likely to become a powerful group to shake the existing industry order. 3. As far as global cooperation is concerned, the partnership led by core leaders is taking shape, but it is still in the early stage.

“…Therefore, as when determining the relationships between members of a social network, the relationship between CPC technologies (nodes) and their application frequency (sides) in a same patent can be used for the construction of a technology network. A node, or player, situated at the center of a technology network is a key player, or key technology [33].…”

With the development of 5G, 5G optical networks have gradually received increasing attention from scholars. However, most studies have focused on discussing the technical or market aspect. Furthermore, their findings have not provided a panorama of the technologies in the 5G domain, nor have they provided a detailed understanding of the key technologies and development trends. An optical network is an indispensable type of infrastructure for the development of 5G. Therefore, defining key technologies in this domain is particularly crucial. The present study used patents for 5G optical networks as the basis of its analysis and constructed a technology network using a network analysis method. Research results indicated that the key technologies provided by 5G optical networks include wireless communication network facilities and local resource management (H04W88 and H04W72), selection arrangements for multiplex systems (H04Q11), and arrangements enabling multiple uses of the transmission path (H04L5). The maturation of optical component technology has paved the way for multiplex communication system technology to flourish and made it one of the key technologies in the development of 5G. Additionally, an analysis of top patentees revealed that information technology companies are the main force in developing 5G optical network technologies. Thus, driven by the market, 5G optical communication has become the technical focus of the private sector. In this study, the researchers constructed a technology network model to explore the technology development trends, and the results may serve as a reference for the government in observing emerging technologies.

“…This is because patents are considered a good proxy for identifying the link and transfer of technological information 9 , especially those that contain more than 90% of the latest technological information in the world 10 . One such method focuses on patent citation networks 11 , where the idea is that a ‘patent cited by subsequent patents has a strong possibility of containing important ideas upon with the later patents are built’ 12 .…”

“…Thus, patent citations networks help not only identify but also predict emerging technologies and their trends 13 to illustrate dynamically changing patterns, evolving knowledge flows in a specific technology and to monitor converging technology phenomena 12 . Box 5 shows the SPARQL query to retrieve the number of patent citations according to the patent categories (i.e.…”

A linked open data representation of patents registered in the US from 2005–2017

Patents are widely used to protect intellectual property and a measure of innovation output. Each year, the USPTO grants over 150,000 patents to individuals and companies all over the world. In fact, there were more than 280,000 patent grants issued in the US in 2015. However, accessing, searching and analyzing those patents is often still cumbersome and inefficient. To overcome those problems, Google indexes patents and converts them to Extensible Markup Language (XML) files using Optical Character Recognition (OCR) techniques. In this article, we take this idea one step further and provide semantically rich, machine-readable patents using the Linked Data principles. We have converted the data spanning 12 years − i.e. 2005−2017 from XML to Resource Description Framework (RDF) format, conforming to the Linked Data principles and made them publicly available for re-use. This data can be integrated with other data sources in order to further simplify use cases such as trend analysis, structured patent search & exploration and societal progress measurements. We describe the conversion, publishing, interlinking process along with several use cases for the USPTO Linked Patent data.
