Citations in the corpus

Explorative and Exploitative Learning from External Corporate Ventures (2005, background): “Unlike European and Japanese patent offices, U.S. Patent and Trademark Office generally includes citations to a broad range of relevant prior patents beyond the most crucial inventions (Michel & Bettels, 2001).”
Knowledge networks from patent data: Methodological issues and research targets (2004, background): ““According to the EPO philosophy a good search report contains all the technically relevant information within a minimum number of citations” ( Michel and Bettels, 2001, p.189 ).”
Mobility of Skilled Workers and Co-Invention Networks: An Anatomy of Localized Knowledge Flows (2009, background): “In short, EPO citations are of better quality than USPTO ones [for a more detailed discussion along these lines, see Breschi and Lissoni (2004) and Michel and Bettels (2001)].14 At the same time, the use of EPO data may impose some limitations on our results; we come back to them in Section 5.1.”
Inventive progress measured by multi-stage patent citation analysis (2005, methodology): “In the end, this leads to US search reports that have mor of the characteristics of a documentary search than that of patentability search (Michel and Bettels, 2001).”
Science dependence of technologies: evidence from inventions and their inventors (2002, result): “…views—amongst inventors about what scientific research actually constitutes. rigorous in enforcing disclosure of prior art, are considered the main reasons why USPTO patents tend to contain an order of magnitude more NPCs than comparable EPO/PCT patents (see e.g. Michel and Bettels, 2001).”
Knowledge Spillovers from Clean and Dirty Technologies (2014, background): “…and citing-cited patent pairs might be ’closer’ both in time and technological content than those extracted from the USPTO [Breschi and Lissoni (2005); Michel and Bettels (2001)] 11 examiners are responsible for 63% of citations on the average patent, and that 40% of patents have all citations…”
International Knowledge Diffusion and Home‐bias Effect: Do USPTO and EPO Patent Citations Tell the Same Story?* (2010, neutral): “Turning to EPO citations, Maruseth and Verspagen (2002) use a crosssection of 112 European regions to show that EPO patent citations are geographically localized.”
Measuring innovative performance: is there an advantage in using multiple indicators? (2003, background): “Patent specialists are somewhat sceptical about the counting of patent citations without the necessary underlying citation reports that accompany each patent (Michel and Bettels, 2001).”
