The purpose of this research is to grasp the purpose of patent applications by companies. Based on this, we grasped the purpose of the patent application through consideration of previous research, selected 10 factors through expert Delphi, and conducted a questionnaire survey on these factors among practitioners in charge of patents in Chinese companies. Analysis results, Improve the technological image of your company, For use in negotiation: cross licensing, joint venture, Improve the situation in R&D cooperations, Enhance Reputation, Measure performance, Aacquire venture capital, Prevent patent infringement suits, Licensing Revenue, competitors' patenting and application activities, prevent copying or protect own technology from imitation. We hope that the results of this research will be useful as practical guidelines for understanding and applying factors that companies should prioritize when filing patent applications.

When high carbon steel is heated in an appropriate austenizing temperature range and subjected to austempering, the size and shape of lamellar structure can be controlled. The high carbon steel sheet having the pearlite structure has excellent elastic characteristics because it has strong restoring force when properly rolled, and is applied in a process known as patenting-process using lead bath. In the case of isothermal treatment using lead-medium, it is possible to quickly reach a uniform temperature due to high heat transfer characteristics, but it is difficult to replace it with process technology that requires treatment to remove harmfulness lead. In this study, we intend to develop fluidization technology using garnet powder to replace the lead medium. After heating the high-carbon steel, the cooling rate was changed by compressed air to the vicinity of the nose of the continuous cooling curve, and then maintained for 90 s and then exposed to room temperature. The microstructure of the treated specimens were analyzed and compared with the existing products treated with lead bath. The higher the flow rate of compressed air, the faster the cooling rate to the pearlite transformation temperature, so lamellar spacing decreases and the hardness tends to increase.

Patents often serve as leading indicators of technological change. This patenting activity reflected R&D (Research & Development) of new technology. The purpose of this study is to set up a forecasting model that anticipate the number of domestic patent applications and the number of patents granted relating to R&D inputs (R&D expenditure, R&D manpower) at the level of three industrial sectors in Korea : electrical-electronic, machinery, chemical etc. In this study, forecasting models were used trend extrapolation and a set of regressions. Both Theil's inequality coefficient and MAE(Mean Absolute Error) were utilized to test the precision of predicted value. The patent data and the R&D data were based on Indicators of Industrial Technology data throught 1980 to 1996. The major results obtained in this study are as follows (1) The regression model is more useful for forecasting the trends of the number of patent applications and patents granted than the trend extrapolation method. (2) The variance of Theil's inequality is smaller in patent applications than in patent granted.

미래의 기업 환경은 유형 자산으로서의 물질적인 자산보다는 지적재산권 등의 무형 자산에 대한 중요성이 더욱 강조될 것이다. 지적재산권 중 특허의 가치를 통하여 기업의 성과가 변화함을 보인 많은 선진국의 사례 연구-Machluo(1958)으로부터 시작하여 Mansfield(1965), Beck. R(1976), Parker. J(1978), Rosegger. G(1980), Scherer. F(1980) 등 1990년 이후는 무수히 많음-는 미래 기업 경쟁력이 질적 가치가 우수한 특허를 얼마나 보유하고 이를 얼마나 효율적으로 관리하는가에 달려있음을 보여주고 있다. 본 연구는 국내 화학기업의 특허관리 유형을 5가지 특허 지표들-국내특허출원건수(relative patent applications), 국내특허등록건수(patent granted), 유효특허건수 (valid patents), 집중도(concentration of patents in subclass), 국제특허출원건수(overall international patent applications)-을 통하여 구분하였으며, 이들 변수를 가지고 군집화 하였을 때 각각에 해당하는 클러스터에서 기업성과에 차이가 나타나는지 알아보았다. 본 연구에서 특허를 기업성과와 관련시켜 설명한 점은 기술혁신 능력 내지는 기술경쟁력을 측정하는 척도로서 특허를 바라본 것이며, 특허의 전략적 관리와 활용이 독점적 시장 우위의 확립과 경제적 성과 향상, 통합적인 경쟁력 강화 측면에서 기업의 성공을 가져올 것으로 보기 때문이다.

The rising pace of technological change in information and communications technology (ICT) has provoked technological convergence by providing a new mode of diversification. This paper investigates the nature of ICT-based converging technologies by examining comparative empirical evidence on converging versus nonconverging technologies in relation to the following issues: patent application trends, concentration across technologies, the concentration of patenting activity across firms, R&D efforts, and a technology impact index. For this study, a new operational definition of ICT-based converging technology is derived, and a massive quantity of patents, up to around 600,000, is analyzed. This study follows the International Patent Classification as well as the modified European Commission's industry classification system for the classification of technologies and industries, respectively.

Effects of manufacturing conditions, such as austenitizing temperature, patenting temperature and carbon content in steels, on mechanical properties, especially on reduction of area (RA), of hyper-eutectoid steel wires were investigated. RA increased and then decreased with transformation temperature. This was attributed to the presence of abnormal structures in steels transformed at low transformation temperatures and the occurrence of shear cracking during tensile testing of steels transformed at high transformation temperatures. The increase of austenitizing temperature resulted in the increased austenite grain size and consequently the decrease of RA. The decrease of RA with increasing the carbon content in steels was attributed to the increased fraction of cleavage fracture in tensile fractured surfaces.

이 연구에서는 어머니의 자녀 양육 행동에 대한 청소년과 어머니간의 지각 차이와 청소년의 적응을 연관시켜 고찰하였다. 자료 수집은 질문지를 통해 이루어졌으며, 참여자들은 미국 동부 소도시에 거주하는 82명의 9 학년 남녀 학생과 어머니들이었다. 자료 분석 결과, 평균적으로는 어머니들이 청소년 자녀들보다 자신의 자녀 양육 행동을 더 긍정적으로 지각했다. 청소년의 적응을 어머니와의 지각 차이에 따라 살펴 본 결과, 어머니의 양육 행동을 어머니 보다 긍정적으로 지각하는 청소년들이 어머니 보다 부정적으로 지각하는 청소년 보다 문제 행동을 하는 경향이 낮았으며, 자신감은 높았다. 또한, 어머니의 양육행동을 어머니 보다 긍정적으로 지각하는 청소년들이 그렇지 못한 청소년들에 비해 어머니와 원활한 의사소통을 하는 것으로 나타났다. 이 연구의 결과들은 청소년과 어머니간의 지각 차이가 측정 상의 문제만이 아닌 청소년 발달과 연관 있는 요인임을 지적한다. 그리고, 지각 차이를 연구할 때는 그 차이의 크기 뿐 아니라 청소년과 어머니 중 어느 편의 지각이 더 부정적인지도 고려해야 한다는 점을 지적한다.

Patents are widely used in the literature as a measure of firm-level innovation. It is regarded that patents improve a firm's operational environment and ultimately increase the value of the firm. However, the relationship between patents and firm value in Korea is under-explored in the literature due to the difficulty of constructing datasets. This paper examines whether patents in Korea increase the market value of a firm. To do this, I exploit novel data on firm-level patents and financial information of all listed Korean companies during the period of 1993-2015 and estimate the non-linear production-function type of Tobin's q equations on R&D, patents, and citations. Surprisingly, I find that patents and citations are weakly associated with firm value, while R&D is strongly associated with an increase in firm value. These results direct imply that policymakers in Korea should enhance patenting incentives to encourage firms to innovate.

We decompose the patent increase over the period 1982 through 2000 using the data provided by KIPO(Korean Intellectual Property Office) and also compare our results to U.S. experiences. First, we show that the contribution of the increase in the R&D spending accounts for $71\%$ of patent increase between 1982 and 2000. Second, an overall increase in patent intensity measured by patent-R&D ratio between 1982 and 2000 is explained by $234\%$ of the changes in the patent yields in individual industries rather than by the reallocation of resources. Third, we find that there is structural change in patent intensity and patenting between 1994 and 1995. The patent yields in individual industries account for $86.4\%$ of patent increase between 1994 and 1995. Fourth, two high tech fields, electrical machinery and precision instrument, account for about $80\%$ of the patent increase.

Using panel data, this paper investigates the impacts of the strengthening of intellectual property rights (IPRs) on innovative activity. The estimation results indicate the following important implications. First, IPRs alone do not play a significant role. Second, the effect of IPRs is strong and significant only when it is interacted with complementary environments for innovation. This finding suggests that IPRs play a significant role only via a specific channel of interaction such as the stage of economic development, institutional environment and trade openness. Third, the significant correlation is not identical across countries implying that some countries were positively affected while others were negatively affected. Those countries are identified as well.
