“…For instance, Alcacer and Gittelman (2006) find that examiners add a larger proportion of self-citations than the inventors themselves. Hedge and Sampat (2009) find that examiner citations are more significantly associated with patent value. Without being an indication for knowledge flow, examiners' involvement in the prior art citation process can also be viewed as a smoothing process that insures a thorough citation of prior art.…”

Document publié chez l'éditeur commercial ABSTRACTDiscovering and assessing fields of expertise in emerging technologies from patent data is not straightforward. First, patent classification in an emerging technology being far from complete, the definitions of the various applications of its inventions are embedded within communities of practice. Because patents must contain full record of prior art, co-citation networks can, in theory, be used to identify and delineate the inventive effort of these communities of practice. However, the use patent citations for the purpose of measuring technological relatedness is not obvious because they can be added by examiners. Second, the assessment of the development stage of emerging industries has been mostly done through simple patent counts. Because patents are not all valuable, a better way of evaluating an industry's stage of development would be to use multiple patent quality metrics as well as economic activity agglomeration indicators. The purpose of this article is to validate the use of 1) patent citations as indicators of technological relatedness, and 2) multiple indicators for assessing an industry's development stage. Greedy modularity optimization of the 'Canadian-made' nanotechnology patent co-citation network shows that patent citations can effectively be used as indicators of technological relatedness. Furthermore, the use of multiple patent quality and economic agglomeration indicators offers better assessment and forecasting potential than simple patent counts.

“…For the purpose of delineating a journal set within the domain of the Science Citation Index, patents thus do not seem of much help (HEDGE & SAMPAT, 2005;SAMPAT, 2006: p. 784, note 28;MEYER, 2006). We don't expect that European or Japanese patents would perform much better in this respect except that they would, of course, control for the regional bias in the U. S. database (NARIN et al 1997).…”

The Journal Citation Reports of the Science Citation Index 2004 were used to delineate a core set of nanotechnology journals and a nanotechnology-relevant set. In comparison with 2003, the core set has grown and the relevant set has decreased. This suggests a higher degree of codification in the field of nanotechnology: the field has become more focused in terms of citation practices. Using the citing patterns among journals at the aggregate level, a core group of ten nanotechnology journals in the vector space can be delineated on the criterion of betweenness centrality. National contributions to this core group of journals are evaluated for the years 2003, 2004, and 2005. Additionally, the specific class of nanotechnology patents in the database of the U.S. Patent and Trade Office (USPTO) is analyzed to determine if non-patent literature references can be used as a source for the delineation of the knowledge base in terms of scientific journals. The references are primarily to general science journals and letters, and therefore not specific enough for the purpose of delineating a journal set.

“…Hegde and Sampat (2009) further show that examiner added citations are better predictors of patent renewal than applicant added citations. In addition, examiner citations are more likely to be added when there is technological and geographical distance between citing and cited patent (Criscuolo and Verspagen, 2008).…”

Document publié chez l'éditeur commercialDocument issued by the commercial publisher Mention légale:Legal notice:In all cases accepted manuscripts should link to the formal publication via its DOI AbstractThis article explores whether the relationship between the breath of technological integration (recombination distance) and the breath of an invention's subsequent application (basicness) is moderated by the sector of activity (private or public), sciencelinkage strength and industry characteristics. Our analysis of Canadian nanotechnology patents granted between 1990 and 1997 shows that although private organizations generally yield smaller rates of basic inventions than public organizations, increases to recombination distance by the former increases invention basicness at a higher rate; increasing reliance upon basic science moderates the relationship between recombination distance and basicness; and increases to recombination distance in emerging sciencebased industries increases invention basicness at a higher rate. These findings have implications regarding the debate around the efficiency of the academic enterprise model. organizations, increases to recombination distance by the former increases invention basicness at a higher rate; increasing reliance upon basic science moderates the relationship between recombination distance and basicness; and increases to recombination distance in emerging science-based industries increases invention basicness at a higher rate.
