标准必要专利的许可谈判对于促进标准的广泛实施并促进市场竞争和创新至关重要。明确标准必要专利权人与标准实施方进行善意许可谈判的义务并制定相关规则有助于解决“专利劫持”和“专利反向劫持”等问题,促进许可谈判顺利进行,提高标准实施效率。本文明确了建立标准必要专利许可善意谈判规则的必要性,分析了标准必要专利善意谈判规则的基础原则,梳理了美国、欧盟和日本关于标准必要专利善意谈判规则的实践模式,基于上述考虑提出了标准必要专利善意谈判制度框架的建构。 相似文献

如何协调处理服务标准化和个性化之间的矛盾,是长期以来困扰服务企业的重要难题之一。服务标准化有益于改进管理,提升服务效率,保证服务质量,服务个性化则有助于实现更高的顾客满意度。然而简单的服务标准化或是服务个性化在实践中都会存在一定的障碍。为了更好促进效率和质量的提升,应该积极促进统一的国家标准、行业标准和地方标准向更高规格、更具个性的企业标准转化,促进以企业为导向的服务标准向以顾客为中心的服务标准转化,促进个性化服务向标准化服务转化,要以企业服务标准化实现顾客眼中个性化。 相似文献

A method is proposed for estimating the parameters of a mixture of exponential and Weibull distributions for which the accuracy of preliminary estimates obtained by graphical analysis is refined in accordance with the criterion of maximum likelihood. The efficiency of the proposed method is supported by the results of statistical modeling. 相似文献

A novel method for the determination of the optical properties of tissue from time-domain measurements is presented. The data analysis is based on the evaluation of the first moment and the second centralized moment, i.e., the mean time of flight and the variance of the measured distribution of times of flight (DTOF) of photons injected by short (picosecond) laser pulses. Analytical expressions are derived for calculation of absorption and of reduced scattering coefficients from these moments by application of diffusion theory for infinite and semi-infinite homogeneous media. The proposed method was tested on experimental data obtained with phantoms, and results for absorption and reduced scattering coefficients obtained by the proposed method are compared with those obtained by fitting of the same data with analytical solutions of the diffusion equation. Furthermore, the accuracy of the moment analysis was investigated for a range of integration limits of the DTOF. The moment analysis may serve as a comparatively fast method for evaluating optical properties with sufficient accuracy and can be used, e.g., for on-line monitoring of optical properties of biological tissue. 相似文献

An approximate analytical expression is derived for the velocity of the front of the wave of change of boiling modes on a
rod and on a plate. The impact of the Thomson effect and of the heater orientation in the gravity field is included. Adequate
agreement is demonstrated between the derived relations and experimental data. 相似文献

Conventional methods for summation of direct measurement errors are considered. Conditions under which these methods provide consistent results are stated. It is proposed to utilize for characteristic of the total error, its interval estimator or the half-sum of the value obtained by adding up its arithmetic and geometric random errors.Translated from Izmeritel'naya Tekhnika, No. 4, pp. 10–12, April, 1995. 相似文献
