“…As for the studies of research impact, citation count is used as an indicator to present the level of impact (Moed 2000;Albert and Plaza 2004). Except for the cited patent count, counting numbers of shared patent citations, as well as patent coupling, were applied to establishing the technological relationships among countries, assignees, inventor and techniques (Lo 2007(Lo , 2008.…”

This paper provides an overview of the progression of technology structure based on patent co-citation networks. Methods of patent bibliometrics, social network analysis and information visualization are employed to analyze patents of Fortune 500 companies indexed in Derwent Innovations Index, the largest patent database in the world. Based on the co-citation networks, several main technology groups are identified, including Chemicals, Petroleum Refining, Motor Vehicles, Pharmaceuticals, Electronics, etc. Relationships among the leading companies and technology groups are also revealed.

“…Firms in the pharmaceutical industry are critically dependent on the patent system for appropriation of returns from R&D. Narin (1994) applied bibliometric methods, including patent citation analysis, to establish the use of patent bibliometric methods, and patent bibliometrics have been used to investigate several technology fields (Acosta et al 2009;Bhattacharya and Meyer 2003;Lo 2007Lo , 2008Van Looy et al 2007;Wang et al 2010;Yuan et al 2010). Most studies use patent bibliometrics primarily to address issues of patent or citation count to obtain an overall view of the sample (Lo 2007(Lo , 2008McMillan and Hamilton 2007). For the patent count, the number of patents indicates the productivity.…”

“…This indicator may be applied to country-, assignee-, inventor-and technology-level analysis (Acosta et al 2009;Lo 2007Lo , 2008Yuan et al 2010). For the citation count, the forward citation counts indicate the level of impact or the quality of a firm's patents, since the frequent citation of a patent provides useful technological knowledge for other patents (Acosta et al 2009;Lo 2007Lo , 2008McMillan and Hamilton 2007). Drawing on previous studies, it is appropriate to depict the pattern of drug patents in the Orange Book by measuring patent and citation count.…”

Tracking R&D behavior: bibliometric analysis of drug patents in the Orange Book

2011

View full text Add to dashboard Cite

The Publication Approved Drug Products with Therapeutic Equivalence Evaluations (commonly known as the Orange Book) identifies drug products approved by the United States Food and Drug Administration (USFDA) for safety and effectiveness, and provides substantial information on new drug applications (NDAs) with patent data. To explore the patterns among drug patents in the Orange Book, this study used patent bibliometric analysis. The productivity and impact are presented at the assignee level and applicant level, respectively, and the applicant's patent portfolio is further discussed. 2,033 drug patents are identified in this current study. Our findings indicate that the applicant's patent portfolio in the Orange Book is helpful in revealing the technological capability and patent strategy of the pharmaceutical incumbents. By linking drug data and patent information, this current study sheds light on patent research in the pharmaceutical industry.

“…By counting the number of patents filed/granted each year, the growth of the research productivity could be drawn. The method was applied to analyze the productivity on countries (Fu et al 2009;Tseng 2009;Sternitzke 2009;Sharma et al 2008;OECD 2000;Zhou et al 2008;Lo 2007;Chen et al 2005;Bhattacharya 2004;Barroso et al 2003;Trajtenberg 1968;Narin et al 1987Narin et al , 1988, assignees, inventors (Narin 1994;Azagra-Caro et al 2007;Banerjee et al 2000) and technology levels (Yu et al 2009;Lee et al 2009;Sakata et al 2009;Breitzman et al 2002;Grupp et al 1999;Garg et al 1998;Courtial et al 1995). Many researchers have applied patent analysis at national level to show the technology innovation and trend, in this study, not only patent counting on countries and on assignees but also patent counting on technology field and on timeline are used for in-depth analysis of patent information.…”

This research intends to investigate the patent activity on water pollution and treatment in China (1985China ( -2007, and then compares the results with patents data about Triadic patents, South Korea, Brazil and India over the same periods, patents data were collected from Derwent World Patents Index between 1985 and May 2008. For this study, 169,312 patents were chosen and examined. Total volume of patents, technology focus, assignee sector, priority date and the comparison with other countries are analyzed. It is found that patents on water pollution and treatment filed at China have experienced a remarkable increase and the increase rate of patents filed at China change simultaneous with the percentage of domestic applications. However, the number of high quality Triadic patents with priority country as China remains small. Furthermore, in addition to individual patent assignees, both Chinese universities and enterprises also play important roles in patent activity of water pollution and treatment. In addition, the pattern of South Korea's development can provide short-term implications for China and the regularity in Triadic patents' development can provide some guidance to China's long-term development. In contrast, the development pattern of Brazil and India is less influential to China's development. Furthermore, China's technology focuses on water pollution and treatment seem to parallel global and triadic patent trends. This research provides a comprehensive picture of China's innovation capability in the area of water pollution and treatment. It will help China's local governments to improve their regional S&T capability and will provide support the National Water Pollution Control and Treatment Project in China.
