The patent is one of the carriers of scientific research and development, and an indicator of technical innovation. As a promising approach for modeling complex systems, complex networks could provide the sound theoretical framework for developing proper simulation models. Many researchers use the relations of patent citations and transfers to study knowledge propagate and output in the network. However, knowledge flow in patents should be fully considered by substantial and fruitful connections, both in the process of knowledge application and knowledge output. In this paper, we present a two-boundary network model with knowledge application boundary and knowledge output boundary to reveal the patent citation patterns in knowledge flow. The feasibility and effectiveness of the two-boundary network model are proved with theory and experiment. Utilizing 578,678 patents from the United States Patent and Trademark Office between 2015 and 2018 with the two-boundary network model, we put up a fixed effect ordinary least square equation to reveal the patent impacts of different structural patterns. Experimental results show that, in the perspective of structural patterns, the highly impacted patents without assigning are greatly influenced by their scientific literature references and provide knowledge for other assigned patents. However, considering all the fixed effect factors, patents that transfer knowledge from other patents to assigned patents are more likely to become highly impacted patents. Besides, we find the two-boundary network model fits the real patent knowledge flow well by comparing it with the other models. INDEX TERMS Two-boundary network model, knowledge flow, regression equation, fixed effect.

“…Still looking at Figure 8, it is possible to note that the ratio between the quantity of retrieved documents to (i) "forward citation" and (ii) "backward citation" outnumbers the unit by 2.3 times, thus indicating that the 301 "breakthrough inventions" documents analyzed in this study presented a strong impact on subsequent technology generations [25]. Technological Trajectories Studies of Sugarcane Ethanol Production Using Patent Citation DOI: http://dx.doi.org /10.5772/intechopen.88428 Moving on, the 3506 patent documents in "forward citation" were treated and filtered through extended family, resulting in 2406 original documents of patent family (no document doubling).…”

The production of ethanol from sugarcane has migrated from the first to the second-generation thanks to the biotechnological advancement in the production process. From the survey of patent documents in the area, it is possible to highlight the most relevant patents according to the impact index, measured by the number of citations, and to evaluate the technological trajectories involved in the production of ethanol using a patent citation as a methodology. In addition, it is possible to identify the main actors involved in the technological field, as well as the network of international collaborators. In this context, the study of patent citations will help better understand the main technological advances and global geopolitics in an environment of globalization of technological innovations.

“…Researchers have created countless patent quality indicators to determine the potential impact of a given invention (Kapoor et al, 2015). Despite the existence of different patents quality indicators, citation-based indicators are the most used by researchers (Aristodemou & Tietze, 2018;Chang et al, 2018;Kapoor et al, 2015). Citation-based indicators allow to identify the links between patents and helps to evaluate the originality and relevance of the innovation (Chang et al, 2018).…”

There is an intense discussion on the impact of the quality of patents on innovation and economic development. Consequently, measuring the quality of patents becomes an essential issue to understand how it affects the innovation system (IS). This paper shows a systematic review of patent quality indicators and their contribution to the literature. Additional to the systematic review, a dynamic behaviour hypothesis is developed to comprise how patent value indicators can be used to create a set of strategies to improve the innovation of the renewable energy sector. Our results show a novel framework for analysing the effects of patent value on the IS that could be useful for renewable energy diffusion in Latin-America.
