二、国际风电技术专利分析世界能源消耗量的持续增加，使全球范围内的能源危机形势愈发明显，缓解能源危机、开发可再生能源、实现能源的可持续发展成为世界各国能源发展战略的重大举措。
风能作为可再生能源的重要类别，在地球上是最古老、最重要的能源之一，全球范围内的巨大蕴藏量、可再生、分布广、无污染的特性，使风能发电成为世界可再生能源发展的重要方向。
1、国外风电专利的技术竞争2008年3月7日，路透社报道称，GE公司向美国国际贸易委员会（ITC）提起诉讼，指控三菱重工（MHI）公司侵犯了其风力发电涡轮机的相关专利，并要求在美国地区禁止进口三菱产风力涡轮机。
GE称被侵犯的专利是有关提高发电机运行效率的变速控制技术（variable speed control technology），专利号：US5083039 和US6921985。
MHI方面的回复则是否认侵犯专利权。
风电产业中的又一场专利之战正拉开序幕。
GE：美国市场的老大地位不可撼动美国最大的风力机制造商GE风能（GE Wind Energy），是GE集团近年来的重要新增业务。
继2002年5月收购安然（Enron）的风能部门之后，于2002年起正式成立并投入运营，总裁Steve Zwolinski走马上任。
此后，对风机技术及风能业务进行整合和提升式的战略管理，机组的建造和设计主要在加利福尼亚、佛罗里达、西班牙、德国和荷兰等地完成，产品主要满足国内科罗拉多（Colorado）、加利福利亚（California）等州风电场建设之需，也有部分出口至英国、比利时等国。
随着市场需求的激增，GE的风力涡轮机产量猛增。
GE公司在2007年提供了2.3GW的新建风力发电项目，相比前一年增加了100%，占据美国市场新增总量的45%，几乎是整个美国在2006年风力发电业的总装机容量。
GE集团更计划在2010年前把可再生能源领域投资增加一倍，至60亿美元。
GE集团的金融子公司认为，在两年内，风能和太阳能等替代能源将占到其能源及水项目总投资的近四分之一，而2006年的比例还是10%。
展会2008；115京■策划／执行本刊报道组国际风能大会开幕啦在中国可再生能源学会风能专业委员会副理事长施鹏飞的日程安排表里，2008年10月29日一51日用红笔重重的圈了起来，在他看来，在这几天里举办的“第四届全球风能大会”是不容错过的。
近年来，在中国大力倡导发展可再生能源的大背景下，风力发电市场呈现井喷之势，风电装机容量连续保持高速增长，“2008年上半年新增风电装机容量超过200万kw，到年底累计装机容量将超过100077kW。
”施鹏飞向记者介绍。
风电事业的迅速发展，也催生了行业展会的火爆行情。
一年下来大大小小的风电展会不计其数，各个展会之间的明争暗斗愈演愈烈，然而这次由全球风能理事会(G W EC)．中国资源综合利用协会可再生能源专业委员会、中国可再生能源学会风能专业委员会主办的2008北京国际风能大会暨展览会、第四届全球风能大会还是吸引了众多眼球。
施鹏飞认为这届展会拥有其它展。
参展企业展示中国可再生能源学会风能专业委员会副理事长施鹏飞会不可比拟之处，“这是全球风能理事会的年会，每年在不同国家举办，2008年轮到北京。
由于世界上主要风电机组制造商都是G W E c的成员，代表了国际风电产业的主流，无论是国外还是国内风能界都能够在这个平台上进行更深层次的交流。
”这也正是此次展会吸引国内外主要整机和部件制造商、风电咨询机构参展的理由，由此可见，这届展会的代表面将更广、展会上展示的技术也埃斯倍传动系统(青岛)有限公司德国埃斯倍传动系统公司是世界知名的电子传动系统制造商，也是风力发电工业重要的电子控制系统供应商，在风力能源设备的运用领域拥有世界领先的生产能力和先进的技术水平，主522008．10电力系统装备I 要提供设备制造、销售和服务。
2005年在青岛市高新技术产业区投资成立埃斯倍传动系统(青岛)有限公司，从事风力能源设备驱动和控制系统的生产和销售，以满足亚洲风电市场。
将代表业界最高水平。
我们常常用一些数字来描述一届展会举办的是否成功，比如参展商和观众人数，然而在目前我国风力发电事业发展的关键时期，这些简单数字背后蕴藏了哪些更为深远的意义?。
律师帮您办门户:从无叶风扇知识产权问题谈起知识产权管理律师郑志锐浙江东孚律师事务所一直在关注无叶风扇产品知识产权问题的相关信息,最近就有两篇相关报道：英国《金融时报》报道的《山寨无叶风扇令戴森公司头痛》与《信息时报》报道的《怎么我们都在“山寨”？》。
这两篇报道都使用了“山寨”一词，且都作为贬义使用，本文不以道德来评判，同时也认为没有事实基础的道德评判是会令人展开不理智的推断，更何况涉及无叶风扇产品问题的事实更多的依赖于法律事实的确定，他与行为品德的判断具有很大的差异。
《山寨无叶风扇令戴森公司头痛》报道中指出：“据戴森公司表示，他们2008年就在中国申请气流倍增器的专利，但至今没有得到批复。
”这似乎在批判中国的专利保护制度，实际上，对发明专利的授权时间而言，这是很正常的，全世界很多国家都如此。
在几个月之前，我甚至有个观点：戴森公司对无叶风扇产品保护乏力，完全是源于对中国专利制度的无知和掌握、利用技能上的匮乏。
现今来看，戴森公司意识到了这个问题，但在行动上还仍不免乱抛牌，同时处处抱怨。
报道中同时指出：“在德国等许多地区，戴森公司不得不寻求销毁反工程仿冒产品，以保护自身品牌。
”说明在中国之外的德国等地，戴森公司遇到的问题也是差不多的。
总结相关的信息，对戴森公司而言，有以下三点：1、专利授权存在问题，包括能否授权与授权时间的快慢的问题；2、在世界各地大量存在非戴森公司出品的无叶风扇；3、戴森公司的维权情况不容乐观。
《怎么我们都在“山寨”？》报道中说及：“为什么在今年春交会上20余家工厂都有摆放（无叶风扇），但是遇到组委会检查就纷纷撤柜规避？”可以得出如下信息：1、全国至少有20余家工厂在生产销售无叶风扇（当然具体多少，不去查证，这并不不影响本文的分析）；2、可能有无叶风扇相关权利人在展会上进行投诉；3、组委会的检查是发生一定作用的，结合投诉人是否出具有效权利凭证、是否提供侵权信息即是否进行有效的投诉，展会的情况一定会不同。
关于热敏电阻控制风扇的专利英文回答：In my opinion, a patent related to controlling a fan using a thermistor can be a valuable asset. This technology has the potential to improve energy efficiency and enhance the overall performance of cooling systems. By using a thermistor, the fan can automatically adjust its speed based on the temperature, ensuring optimal cooling without wasting excessive energy.One example of such a patent is a system that utilizes a thermistor to monitor the temperature of an electronic device, such as a computer or a server. The thermistor is strategically placed near the heat-generating components of the device. When the temperature exceeds a certain threshold, the thermistor triggers the fan to increase its speed, effectively dissipating the heat and preventing overheating.Additionally, the patent can include a control mechanism that allows the user to set specific temperature thresholds and fan speed levels. This way, the fan can be customized to meet the specific cooling requirements of different devices and environments. For example, in a noisy office environment, the user may prefer to set the fan speed to a lower level to minimize noise disturbance, while still maintaining adequate cooling.Furthermore, the patent can incorporate intelligent algorithms to optimize the fan control based on real-time temperature readings. For instance, the algorithm can analyze the rate at which the temperature is increasing or decreasing and adjust the fan speed accordingly. This dynamic control mechanism ensures that the fan responds quickly to temperature changes and provides efficient cooling.Overall, a patent related to controlling a fan using a thermistor can have significant commercial value. It can be applied in various industries, including electronics, automotive, and HVAC systems. The ability to automaticallyadjust fan speed based on temperature not only improves energy efficiency but also prolongs the lifespan of electronic devices by preventing overheating.中文回答：我认为，与使用热敏电阻控制风扇相关的专利可以成为一项有价值的资产。
