    This paper studies how IT investments shape the geography of firm innovation. We focus on the role of investments by US firms in basic internet technology on the organization of innovation. We combine establishment-level IT investment data with data on US patenting activity at the MSA level. Our difference-in-difference econometric estimation approach compares the citationweighted count of co-invented patents among two firm locations before basic Internet technology diffused (i.e., 1992) to the count of patents after its diffusion (i.e., 1998). Our results show that when two firm locations adopt Internet technology, the number of cross-location collaborative patents between them increases compared to an otherwise identical pair without Internet technology. We further find that the link between Internet adoption and cross-location patenting is greatest for firm pairs that have previously been successful innovators, have not collaborated before, and which have different research foci

    International patent families: from application strategies to statistical indicators

    This paper provides an in-depth analysis of the characteristics of international patent families, including their domestic component. We exploit a relatively under-studied feature of patent families, namely the number of patents covering the same invention within a given jurisdiction. Using this information, we highlight common patterns in the structure of international patent families, which reflect both the patenting strategies of innovators and the peculiarities of the different patent systems. While the literature has extensively used family size, i.e. the number of countries in which a given invention is protected, as a measure of patent value, our results suggest that the number of patent filings in the priority country within a patent family as well as the timespan between the first and last fillings within a family are other insightful indicators of the value of patented innovations

    Foreign applications at the Japan Patent Office - An empirical analysis of selected growth factors

    This article aims to evaluate some of the possible factors which could have had a significant role in the increase in the yearly number of foreign patent applications at the Japan Patent Office. The analysed period ranges from 1991 to 2005. In the years considered, foreign applications increased constantly while the number of domestic filings remained almost the same or even decreased. The increase is more striking when compared to analogous figures of the US Patent and Trademark Office and the European Patent Office, where the corresponding ratio did not change too much in the same period. Building on previous literature, this paper analyses the impact of some macroeconomic and structural characteristics of the extending countries, on one side, and, on the other side, some features specific to the receiving country and its Patent Office (here Japan and the JPO). This work tries to capture the relevance of such drivers in the increased amount of foreign patent applications at the JP

    University patenting and technology commercialization – legal frameworks and the importance of local practice

    Get PDF
    The impact of national legislative frameworks on the higher education sector's contribution to technological innovation is heavily disputed. This paper argues that legislative frameworks may stimulate the development of local practices for the management and exploitation of intellectual property (IP), which in turn determine the level of academic patenting. We present case studies of two comparable universities in each of four selected European countries with different histories of national IP legislation. A within-country analysis shows that a wider range and earlier development of local IP management and exploitation practices are accompanied by higher levels of academic patenting, and that increasing similarity of IP practices is associated with decreasing differences in patenting outputs. A preliminary cross-country analysis reveals an expansion in and increasing similarity of practices for IP management and exploitation in countries with different national IP framework histories. We conclude that adopting Bayh-Dole-like legislation may trigger the development of local IP practices, which stimulate patenting. However, it is not always sufficient and definitely not always necessary. The study concludes with some policy recommendations

    From transporter to transceptor: Signaling from transporters provokes re-evaluation of complex trafficking and regulatory controls: Endocytic internalization and intracellular trafficking of nutrient transceptors may, at least in part, be governed by their signaling function

    Get PDF
    When cells are starved of their substrate, many nutrient transporters are induced. These undergo rapid endocytosis and redirection of their intracellular trafficking when their substrate becomes available again. The discovery that some of these transporters also act as receptors, or transceptors, suggests that at least part of the sophisticated controls governing the trafficking of these proteins has to do with their signaling function rather than with control of transport. In yeast, the general amino acid permease Gap1 mediates signaling to the protein kinase A pathway. Its endocytic internalization and intracellular trafficking are subject to amino acid control. Other nutrient transceptors controlling this signal transduction pathway appear to be subject to similar trafficking regulation. Transporters with complex regulatory control have also been suggested to function as transceptors in other organisms. Hence, precise regulation of intracellular trafficking in nutrient transporters may be related to the need for tight control of nutrient-induced signaling

    Systematic Mutational Analysis of the Intracellular Regions of Yeast Gap1 Permease

    Get PDF
    The yeast general amino acid permease Gap1 is a convenient model for studying the intracellular trafficking of membrane proteins. Present at the plasma membrane when the nitrogen source is poor, it undergoes ubiquitin-dependent endocytosis and degradation upon addition of a good nitrogen source, e.g. ammonium. It comprises 12 transmembrane domains (TM) flanked by cytosol-facing N- and C-terminal tails (NT, CT). The NT of Gap1 contains the acceptor lysines for ubiquitylation and its CT includes a sequence essential to exit from the endoplasmic reticulum (ER).Journal ArticleResearch Support, Non-U.S. Gov'tSCOPUS: ar.jinfo:eu-repo/semantics/publishe
