Intellectual property information: A comparative analysis of main information providers

Abstract

After modeling expert user needs with regard to intellectual property information, we analyze and compare the main providers in this specific information area (Thomson DIALOG, Esp@cenet by the European Patent Office, Questel-Orbit, and STN International) in terms of system content and system functionality. The key question is whether the main providers are able to satisfy these expert user needs. For patent information, some special retrieval features such as chemical structure search (including Markush search), patent family references and citations search, biosequence search, and basic informetric functionality such as ranking, mapping, and visualization of information flows are realized. Considering the results of information science research, the practice of patent information shows unexhausted improvement opportunities (e.g., the application of bibliographic patent coupling and co-patent-citation for mapping patents, patent assignees, and technology specialties). For trademark search, users need multiple truncated search (realized) as well as phonetic search and image retrieval (not realized yet).

Mapeamento Tecnológico Em Biodiesel: Pedidos De Patente Depositados No Mundo E Brasil

“…A presente pesquisa consiste na busca por patentes relacionadas ao tema biodiesel, utilizando-se para busca o sistema de base Questel Orbit, (LAMBERT, 2004;DICKENS, 2005;STOCK, STOCK, 2004, 2006FAGUNDES et al, 2014, SEIBOTH et al, 2014DICKEL, et al, 2015;FANTINEL et al, 2015). O sistema de busca Orbit dá acesso à base de dados proprietária da FAMPAT.…”

Espacenet, Patentscope and Depatisnet: A comparison approach

“…5 operators and field identifiers were used to retrieve nanotechnology-related patents with Bayer as an applicant, the keywords "nano" and "tube" in the abstract and 2010 as publication year. When it comes to the number of available search fields in each of the available search interfaces, Patentscope provides the most powerful search interface with 51 search fields available [4], followed by 36 in the command line search of Depatisnet (Expert and Ikofax search) [5], and 16 in Espacenet´s Smart Search [6]. …”

“…Smith [1] compared online host patent databases available in the late eighties, Lambert [2] compared online host databases and the upcoming Internet patent databases in the late nineties and Schwander [3] evaluated patent searching resources comparing professional and free online databases in 2000. The more recent studies are from Stock [4] and González & Zuleta [5], both of which compared some commercial providers with various free providers. None of the studies focused on free of charge sources or gave a direct comparison of their features and functionalities.…”

Are invalid patents still cited?

“…A patent, like an academic paper, can contain citations. Many studies have explored patent citation behavior and patent citation motivation (Azagra-Caro, Mattsson, & Perruchas, 2011;Bhattacharya, Kretschmer, & Meyer, 2003;Lai & Wu, 2005;Stock & Stock, 2006). Patent citations are often used to represent the quality of an innovation and are considered a manifestation of the patent's influence.…”
