透过专利看微处理器的技术发展（四）——中国专利中的多核技术演进分析

本文在调研大量专利文献的基础上,通过跟踪具体专利对微处理器的多核技术进行了深入分析。确定了多核关键技术的发展历程,揭示了不同时期技术要素的特征,以及技术要素的变化,为新产品开发提供线索。特别以多核的两大关键技术（维持Cache一致性和核间通信技术）为例,具体阐述了同一技术的技术演进过程;同时结合中国多核技术的发展现状,预测了多核的发展趋势。     

浅谈企业技术标准与专利工作的结合

随着国内内燃机行业的快速发展,以及先进技术、结构在活塞环制造过程中不断创新,出现了技术标准与专利权并进的趋势,技术标准和专利权的结合可以提升二者的市场影响力。本文对活塞环行业技术标准与专利权结合的必要性,结合后容易产生的问题以及行业技术标准与专利权结合的方式进行探讨。

原子荧光法测定中成药中的砷

利用硝酸-高氯酸消解对中成药进行前处理,以盐酸为测定介质,硫脲-抗坏血酸为预还原剂,硼氢化钾为还原剂,用氢化物发生-原子荧光法测定砷含量。结果表明,砷含量在0~100ng.mL-1浓度范围内线性关系良好(r=0.9997),方法的检出限为0.21ng.mL-1,相对标准偏差(RSD)为0.8%~3.4%,回收率为96.8%~102.1%。     

Searching in Cooperative Patent Classification: Comparison between keyword and concept-based search

International patent corpus is a gigantic source containing today about 80 million of documents. Every patent is manually analyzed by patent officers and then classified by a specific code called Patent Class (PC). Cooperative Patent Classification CPC is the new classification system introduced since January 2013 in order to standardize the classification systems of all major patent offices. Like keywords for papers, PCs point to the core of the invention, describing concisely what they contain inside. Most of patents strategies are based on PC as filter for results therefore the selection of relevant PCs is often a primary and crucial activity. This task is considered particularly challenging and only few tools have been specially developed for this purpose. The most efficient tools are provided by patent offices of EPO and WIPO.This paper analyzes their PCs search strategy (mainly based on keyword-based engines) in order to identify main limitations in terms of missing relevant PCs (recall) and non-relevant results (precision). Patents have been processed by KOM, a semantic patent search tool developed by the authors. Unlike all other PC search tools, KOM uses semantic parser and many knowledge bases for carrying out a conceptual patent search. Its functioning is described step by step through a detailed analysis pointing out the benefits of a concept-based search vis-à-vis a keyword-based search. An exemplary case is proposed dealing with CPCs describing the sterilization of contact lenses. Comparison could be likewise conducted on other PCs such as International (IPC), European (ECLA) or United States (USPC) patent classification codes.
