21 Unconnected component inclusion technique for patent network analysis: Case study of Internet of Things-related technologies
تکنیک ورودی جزء غیر مرتبط برای تجزیه و تحلیل شبکه های ثبت اختراع: مطالعه موردی فن آوری های مرتبط با اینترنت اشیاء-2016
In this study, we propose an unconnected component inclusion technique (UCIT) for patent citation analysis. Our method generates a cluster solution that includes unconnected and connected components of a direct citation network, enabling a more complete analysis of the technology fields. Case studies of Internet of Things-related technologies were con ducted to test the effectiveness of our proposed method. We observed that UCIT increased the number of nodes especially in relatively small networks. Additionally, we analyzed how the clusters changed by adding unconnected patents to the citation network and identified four types of clustering phenomenon. Our method can be used by patent officers, R&D man agers, and policy makers when they want to understand the technology landscape better.

22 Venture capital investments and the technological performance of portfolio firms
ریسک مبلغ سرمایه گذاری شده سرمایه و عملکرد فن آوری شرکت های بزرگ-2016
What is the relationship between venture capitalists’ selection of investment targets and the effects of these investments on the patenting performance of portfolio companies? In this paper, we set out a modelling and estimation framework designed to discover whether venture capital (VC) increases the patentingperformanceoffirmsorwhetherthiseffectisaconsequenceofpriorinvestmentselectionbased on firms’ patent output. We develop simultaneous models predicting the likelihood that firms attract VC financing, the likelihood that they patent, and the number of patents applied for and granted. Fully accounting for the endogeneity of investment, we find that the effect of VC on patenting is insignificant or negative, in contrast to the results generated by simpler models with independent equations. Our findings show that venture capitalists follow patent signals to invest in companies with commercially viable know-how and suggest that they are more likely to rationalise, rather than increase, the patenting output of portfolio firms.

23 The effect of patent litigation and patent assertion entities on entrepreneurial activity
اثر دادخواهی حق ثبت اختراع و ثبت اختراع ادعا اشخاص در فعالیت های کارآفرینی-2016
Article history:Received 22 June 2014Received in revised form 17 June 2015 Accepted 14 July 2015This paper empirically investigates the statistical relationship between levels of patent litigation and ven- ture capital investment in the U.S. We find that VC investment, a major funding source for entrepreneurial activity, initially increases with the number of litigated patents. However, there is a “tipping point” where further increases in the number of patents litigated are associated with decreased VC investment, which suggests an inverted U-shaped relation between patent litigation and VC investment. This appears strongest for technology patents, and negligible for products such as pharmaceuticals. Strikingly, we find evidence that litigation by frequent patent litigators, a proxy for litigation by patent assertion entities, is directly associated with decreased VC investment, with no positive effects initially.© 2015 Elsevier B.V.

24 Do inventors talk to strangers? On proximity and collaborative knowledge creation
آیا مخترعان صحبت کردن با غریبه؟ در نزدیکی و خلق دانش مشترک-2016
Article history:Received 26 October 2013Received in revised form 15 July 2015 Accepted 16 July 2015JEL classification:O31 O33 R11 R23Keywords: Innovation Patents Proximities RegionsKnowledge spillovers Collaboration EthnicityThis paper examines the characteristics of the collaborations between inventors in the United King- dom (UK) by looking at what types of proximities – geographic, organisational, cognitive, social, and cultural–ethnic – between inventors are prevalent in partnerships that ultimately lead to technological progress. Using a new panel of UK inventors this paper provides an analysis of associations between these ‘proximities’ and co-patenting. The results show that while collaboration within firms, research centres and universities remains crucial, external networks of inventors are key feature of innovation teams. The analysis shows that external networks are highly dependent on previous social connections, but are generally unconstrained by cultural or cognitive factors. Geographical proximity is also weakly linked with external networks. Our results suggest that innovation policies should, rather than focus on spatial clustering, facilitate the formation of open and diverse networks of inventors.© 2015 The Authors.

25 Bridging science and technology through academic–industry partnerships
پل علم و فن آوری از طریق مشارکت صنعت علمی-2016
Article history:Received 18 August 2014Received in revised form 15 July 2015 Accepted 21 July 2015Keywords:Economic development Technological change and growth Technological changeResearch and development Government policyPartnerships that foster the translation of scientific advances emerging from academic research orga- nizations into commercialized products at private firms are a policy tool that has attracted increased interest. This paper examines empirical data from the Danish National Advanced Technology Founda- tion, an agency that funds partnerships between universities and private companies. We assess the effect on participating firms’ innovative performance, comparing patent count, publication count and propor- tion of cross-institutional publications between funded and unfunded firms. Specifically, we measure the impact on each of these variables based on three dimensions – small and medium-sized enterprises (SME), younger firms, and size of the collaboration firms participated in – to establish boundary condi- tions. Our results suggest that receiving funding affects firms’ innovative behavior differently depending on the type of firm, where (1) peer-reviewed publications increased significantly more for SMEs and larger projects, (2) granted patents increased significantly up to 4 years after funding for young firms and those in larger projects, and (3) proportion of cross-institutional publications increased significantly more 3 years after funding for all three sample specifications.© 2015 Elsevier B.V.

26 Chinas R&D explosion—Analyzing productivity effects across ownership types and over time
R & D انفجار تجزیه و تحلیل اثرات بهره وری چین در میان انواع مالکیت و در طول زمان-2016
Article history:Received 21 January 2015Received in revised form 3 June 2015 Accepted 24 July 2015Keywords: Productivity R&DChina Ownership type PatentsJEL classification:O32 O33In the past years, Chinese firms increased their spending on R&D substantially and worked on achieving a higher quality level of R&D. We analyze whether different R&D activities show a positive influence on total factor productivity (TFP) for firms of different ownership types and across two time periods. Our panel dataset with annual information allows us to study listed firms over the two time periods 2001–2006 and 2007–2011. Privately owned enterprises (POEs) not only obtain higher returns from own R&D than majority and minority state-owned enterprises (SOEs), they are also able to increase their leading position. Overall strong increases in the size of patent stocks are related to a decreasingly positive or even vanishing influence on TFP. POEs not only produce R&D of the highest quality but are also the only ownership type profiting from higher quality. Up to now research collaborations allow almost no benefit with the only exception stemming from domestic collaborations with individuals. Our comprehensive analysis depicts strengths but also weaknesses of the corporate sector in China. We derive implications for the further development of economic policies.© 2015 Elsevier B.V.

27 Mapping the technological landscape: Measuring technology distance, technological footprints, and technology evolution
نقشه برداری از چشم انداز فن آوری: اندازه گیری فاصله فن آوری، رد پا و فن آوری و تکامل فن آوری-2016
Article history:Received 29 April 2014Received in revised form 23 July 2015 Accepted 3 August 2015Keywords: Technology landscape Knowledge-spillover Recombinant searchWe develop and apply a set of measures that enable a fine-grained characterization of technological capa- bilities based on the USPTO database. These measures can capture the distance between any two patents, and help to identify outlier patents. They also provide a rich characterization of a firm’s technological footprint, including its depth and breadth. The measures also enable researchers to assess the technolog- ical overlap, similarity, and proximity of the technological footprints of two or more firms. At the level of the macro technology landscape, the measures can be used to explore such dynamics as technology agglomeration, knowledge spillovers, and technology landscape evolution. We show applications of each of the measures and compare the results obtained with those that would be obtained with previously existing measures of firm diversity, similarity and proximity, highlighting the advantages of the measures used here.© 2015 Elsevier B.V.
