Trends in Research and Technology Development Related to Zoonosis Control Based on Bibliometric and Patent Analyses–Taking Rabies as an Example

s and claims to identify patent applications related to rabies control. The following analysis was based on results, which included 237 patent applications. 3.3. Annual change in the number of patent applications by country We regrouped the patent applications and applicants for each country to identify possible differences in technology development among various countries. The numbers of PCT applications and applications in each country were stable during 2001–2011, except in China where the number increased relatively. The US had the most patent applications until 2007, but was overtaken by China in 2008. We found that China had a remarkable increase in patent Search formula Number of patent applications retrieved* Survey content 1 PRD = 2001:2011 11,315,347 Priority year 2 (US OR EP OR GB OR DE OR ES OR FR OR IT OR NL OR JP OR CN OR KR OR IN)/PC 20,081,126 Country or patent administration office (the US, the European Patent Office, the UK, Germany, Spain, France, Italy, the Netherlands, Japan, China, Korea, and India) 3 (RABIES OR RABIC OR RABID OR LYSSA)/TI/AB/EAB 1,317
