Department of Management EngineeringFirms participating in printer industries have invested their constrained resources into technology development in order to sustain their competitiveness in the industry. Considering the fast-changing market circumstances, each firm???s own investment decisions on technology portfolio may directly affect their performance. In this study, we analyzed patent data, namely number of forward citations and technological classification data (CPC). Using this data, the technological portfolio of a specific firm can be identified, which can further help our understanding on firms??? R&D investment strategies. Number of studies mainly focused on patent class combinations of individual technology level, but portfolios of patent class at a firm level have been understudied. In this study, we tracked the change of class composition within each firms??? technological patents??? portfolio and attempted to identify practical and theoretical implications to portfolio management. We utilized Entropy Index, Co-occurrence and cosine similarities measurements for each indicating diversification, patent scope and portfolio similarities within each patents??? classification subclasses. Additionally, performance evaluation of each portfolio is conducted using forward citation data. This paper shows that in-depth patent data analysis can allow us to explore deeper insights at various levels, individual technology, products and product lines, and firms sufficing different stories.ope

Supply Portfolio Concentration in Outsourced Knowledge-Based Services

In the extant vertical integration literature, the question of how the firm's portfolio of outsourced work is managed across suppliers has been relatively understudied. We seek to advance this area of research by examining factors that influence how concentrated the firm's outsourcing is among its set of suppliers. Using data on the outsourcing of patent legal services, we find empirical evidence that outsourced knowledge-based service work is concentrated in the hands of fewer suppliers when: (1) it requires greater firm-specific knowledge; (2) there is a higher level of interrelatedness across outsourced projects; (3) the firm's reliance on outsourcing is high; (4) its outsourced projects are focused on a narrower (capability) domain; and (5) the technological dynamism of this domain is low. Our study suggests that examining portfolio-level phenomena in outsourcing is a useful complement to the predominant focus on transaction-level outcomes in prior research because it provides insights into how firms manage tradeoffs across their entire set of outsourced projects.

Empirical Tests Of Optimal Cognitive Distance

This article provides empirical tests of the hypothesis of ‘optimal cognitive distance’, proposed by Nooteboom (1999, 2000), in two distinct empirical settings. Variety of cognition, needed for learning, has two dimensions: the number of agents with different cognition, and differences in cognition between them (cognitive distance). The hypothesis is that in interfirm relationships optimal learning entails a trade-off between the advantage of increased cognitive distance for a higher novelty value of a partner’s knowledge, and the disadvantage of less mutual understanding. If the value of learning is the mathematical product of novelty value and understandability, it has an inverse-U shaped relation with cognitive distance, with an optimum level that yields maximal value of learning. With auxiliary hypotheses, the hypothesis is tested on interfirm agreements between pharmaceutical companies and biotech companies, as well as on interfirm agreements in ICT industries.innovation;organizational learning;ICT;biotechnology;alliances

R&D Portfolios and Pharmaceutical Licensing

We examine how R&D portfolios of drug pipelines affect pharmaceutical licensing, controlling firm size, diversity, and competitors in R&D and product markets. The data collected comprises 329 license-outs and 434 license-ins closed by 54 Japanese pharmaceutical companies between 1997 and 2007. We pay special attention to stage-specific licensing by dividing the innovation process into an early stage and a late stage. Estimates from the fixed-effect GMM model reveal that drug pipelines significantly affect stage-specific licensing. Particularly, the state of drug pipelines is leveled off by license-outs at the early stage and license-ins at the late stage. Theoretical implications are also discussed.R&D portfolios, licensing, pharmaceutical industry, drug pipelines

Technological diversification, coherence and performance of firms.

Technological diversification at the level of the firm, i.e. the expansion of a firm’s technology base into a wide range of technology fields, is found to be a prevailing phenomenon in all three major industrialized regions: US, Europe and Japan, prompting the term multi-technology corporation. Whereas previous studies have provided insights into the composition of technology portfolios of multi-technology firms, little is known about the link between technological diversification and firms’ technological performance. Against a backdrop of the technology and innovation management literature, this article investigates the relationship between technological diversification and technological performance, taking into account the moderating role of technological coherence in firms’ technology portfolios. Hereby, technological coherence is defined as the degree to which technologies in a technology portfolio are technologically related. In order to measure the technological coherence of portfolios, a measure of technological relatedness of technology fields is constructed based on patent citation patterns found in 450,000 EPO patent grants. Two hypotheses are presented in this article: (1) Technological diversification has an inverted U-shaped relationship with technological performance; and (2) Technological coherence moderates the relationship between technological diversification and technological performance positively. These hypotheses are tested empirically using a panel dataset (1995-2003) on patent portfolios pertaining to 184 US, European, and Japanese firms. The firms selected are the largest R&D actors in five industries: Pharmaceuticals & Biotechnology, Chemicals, Engineering & General Machinery, IT Hardware (computers and communication equipment), and Electronics & Electrical Machinery. Empirical results, obtained by fixed-effects negative binomial regressions, support both hypotheses in this article. Technological diversification has an inverted U-shaped relationship with technological performance. While technological diversification offers opportunities for cross-fertilization and technology fusion, high levels of diversification may yield few marginal benefits as firms risk lacking sufficient levels of scale to benefit from wide-ranging technological capabilities, and firms may encounter high levels of coordination and integration costs. Further, the results show that the net benefits of technological diversification are higher in technologically coherent technology portfolios. If firms build up a technologically coherent diversified portfolio, the presence of sufficient levels of scale is ensured and coordination costs are limited. This article clearly identifies the important role of technological coherence and points out in the discussion session the relevance of future research on interface management practices directed to the realization of the benefits of technological diversification.technology diversification; technology relatedness; innovation; firm performance;

Technological activities and their impact on the financial performance of the firm: Exploitation and exploration within and between firms.

This article analyzes the financial performance consequences of technology strategies categorized along two dimensions: (1) explorative versus exploitative and (2) solitary versus collaborative. The financial performance implications of firms’ positioning along these two dimensions has important managerial implications, but has received only limited attention in prior studies. Drawing on organizational learning theory and technology alliances literature, a set of hypotheses on the performance implications of firms’ technology strategies are derived. These hypotheses are tested empirically on a panel dataset (1996-2003) of 168 R&D-intensive firms based in Japan, the US and Europe and situated in five different industries (chemicals, pharmaceuticals, ICT, electronics, non-electrical machinery). Patent data are used to construct indicators of explorative versus exploitative technological activities (activities in new or existing technology domains) and collaborative versus solitary technological activities (joint versus single patent ownership). The financial performance of firms is measured via a market value indicator: Tobin’s Q index. The analyses confirm the existence of an inverted U-shape relationship between the share of explorative technological activities and financial performance. In addition, it is observed that most sample firms do not reach the optimal level of explorative technological activities. These findings point to the relevance of creating a balance between exploitation and exploration in the context of technological activities. Moreover, they suggest that, for the majority of R&D intensive firms, reaching such a balance between exploration and exploitation implies investing additional efforts and resources in exploring new knowledge domains. The analyses also show that firms, engaging more intensively in collaboration, perform relatively stronger in explorative activities. At the same time, a negative relationship between the share of collaborative technological activities and a firm’s market value is observed. Contrary to our expectations, it is collaboration in explorative technological activities, rather than collaboration in exploitative technological activities, that leads to a reduction in firm value. These findings question the relevance of open business models for technological activities. In particular, they suggest that the potential advantages of collaboration for (explorative) technological activities (i.e. access to complementary knowledge from other partners, sharing of technological costs and risks) might not compensate for the potential disadvantages, such as the incurred increase in coordination costs and the need to share innovation rewards across innovation partners.

Productivity and Heterogeneous Knowledge: Exploring the Relationship in a Sample of Drug Developers

This paper aims to investigate the effect of knowledge characteristics on the total factor productivity of firms developing drugs in the pharmaceutical industry. We decompose knowledge into knowledge associated with the technological firm portfolio and knowledge related to R&D projects, which represent drug development at the clinical testing stage. The latter is attributed to the knowledge of relevant markets where the drugs will be sold. The results show that the effect of technological coherence vs. market coherence and of accumulated knowledge on the productivity of firms differs. Productivity increases with the number of patents and decreases with the patent diversity and project portfolio coherence. When considering only the project knowledge, the diversity of the project portfolio positively affects productivity.total factor productivity, diversity,,coherence, knowledge

Patent Strategies of Small High-tech Firms in a Broader Context: the Case of International Learning

The current paper explores the patenting behavior of small high-tech firms in a wider strategic context. It particularly addresses why small high-tech firms apply for patents and what makes them not to do so, and connects this with international learning. The general idea is that small high-tech firms suffer from shortage in resources causing them to be reluctant in application for patents. However, not having protected their inventions by patents may weaken their position in attracting investment capital and in establishing strategic relationships, including learning relationships abroad. Drawing on the literature and on survey data of 100 academic spin-off firms, the influence of patent behavior (among other factors) on adoption of international learning is estimated. It appears that half of the spin-off firms works with inventions protected by patents and that a slightly larger share (60%) has adopted the strategy of international learning. Our explorative analysis using a logit model of international learning indicates that not having protected inventions through patents tends to block learning in international networks.Artykuł porusza istotną rolę ochrony patentowej firmach technologicznych. Autorzy stawiają pytania: Jakie są przesłanki wnioskowania o ochronę patentową w małych firmach? Dlaczego jedne firmy starają się działać w oparciu o ochronę własności przemysłowej a drugie nie?, na które starają się udzielić odpowiedzi w oparciu o badania. Ważnym zagadnieniem poruszanym w rozdziale jest międzynarodowy proces uczenia się firm ochrony własności intelektualnej. Generalna idea publikacji podkreśla niechęć małych firm technologicznych w aplikowaniu o ochronę patentową. Jednakże można wyraźnie zauważyć, w przypadku braku strategii ochrony patentowej, utratę atrakcyjności inwestycyjnej małych firm ukierunkowanych na rynek międzynarodowy. Artykuł opiera się na analizie źródeł wtórnych i pierwotnych. 100 firm akademickich zostało zbadanych by zidentyfikować wpływ strategii ochrony patentowej na zachowanie się na rynku międzynarodowym. Analiza oparta jest o model wykładniczy uczenia się na rynkach międzynarodowych. Połowa małych firm technologicznych chroni swoją własność przemysłowa patentem a wśród nich trzy na pięć firm adoptuje wiedzę z rynków międzynarodowych. Te firmy, które nie stosują ochrony patentowej niewątpliwie blokują sobie możliwości uczenia się na rynkach zagranicznych.Druk materiałów sfinansowano ze środków Ministerstwa Nauki i Szkolnictwa Wyższego w ramach projektu „Kreator innowacyjności – wsparcie innowacyjnej przedsiębiorczości akademickiej”

Unbundling dynamic capabilities for inter-organizational collaboration

Purpose The purpose of this paper is to explore two distinct subsets of dynamic capabilities that need to be deployed when pursuing innovation through inter-organizational activities, respectively, in the contexts of broad networks and specific alliances. The authors draw distinctions and explore potential interdependencies between these two dynamic capability reservoirs, by integrating concepts from the theoretical perspectives they are derived from, but which have until now largely ignored each other – the social network perspective and the dynamic capabilities view. Design/methodology/approach The authors investigate nanotechnology-driven R&D activities in the 1995–2005 period for 76 publicly traded firms in the electronics and electrical equipment industry and in the chemicals and pharmaceuticals industry, that applied for 580 nanotechnology-related patents and engaged in 2,459 alliances during the observation period. The authors used zero-truncated Poisson regression as the estimation method. Findings The findings support conceptualizing dynamic capabilities as four distinct subsets, deployed for sensing or seizing purposes, and across the two different inter-organizational contexts. The findings also suggest potential synergies between these subsets of dynamic capabilities, with two subsets being more macro-oriented (i.e. sensing and seizing opportunities within networks) and the two other ones more micro-oriented (i.e. sensing and seizing opportunities within specific alliances). Practical implications The authors show that firms differ in their subsets of dynamic capabilities for pursuing different types of inter-organizational, boundary-spanning relationships (such as alliances vs broader network relationships), which ultimately affects their innovation performance. Originality/value The authors contribute to the growing body of work on dynamic capabilities and firm-specific advantages by unbundling the dynamic capability subsets, and investigating their complex interdependencies for managing different types of inter-organizational linkages. The main new insight is that the “linear model” of generating more innovations through higher inter-firm collaboration in an emerging field paints an erroneous picture of how high innovation performance is actually achieved

Heterogeneity in learning processes and the evolution of dynamic managerial capabilities as a response of emergence of biosimilar market: evidence from the Indian pharmaceutical industry

This paper examines heterogeneity in the response of Indian firms to the emergence of a new segment in the pharmaceutical generics market – biosimilars. The necessary diversity of the knowledge base and regulatory requirements underlying biosmilar products have created significant technological capability and market access challenges for Indian firms. This is but the latest development which adds to an existing catalogue of challenges including the decline of the traditional generics markets, regulatory hurdles in advanced country markets and failures in managing new drug development. Using case studies of three Indian firms we show that dynamic managerial capability is a key driver of heterogeneity in learning processes involved in acquisition of technological capabilities for biosimilars and market access strategies. It further highlights the important role of pre-existing capabilities in enabling and constraining the development of new biosimilar capabilities
