怎样对计算机软件进行更恰当的法律保护，这是一个国际性的问题，但至今各国的保护模式尚不统一，争论不断。这种争论源于软件本身的特殊性，它既具有明显的作品性又具有工具性。由于在软件产业发展初期，美国采用著作权法对其进行法律保护并否认软件的专利性，而后利用其在国际上的霸权地位强制其他国家和地区推行此保护模式，这是长期以来软件被多数国家作为著作权法保护的客体而被排斥在专利保护范围之外的一个重要原因。经过最近几十年的发展变化，美国逐渐放开了对计算机软件的专利保护限制，从最初的否定态度，转变为后来承认并加强软件的专利保护，欧盟、日本也基本于此一致，通过相关立法或者司法判例逐步扩大对软件的专利保护。 目前，计算机软件的专利保护模式已经被很多国家采用，我国旧的《专利审查指南》对有计算机软件的专利审查条件非常严格，规定计算机程序只有能使硬件设备在技术上产生创造性的改进，才可能被授予专利权。当时软件只是作为硬件的附属物得到专利保护，软件本身无论如何都不具有专利性。后来为了适应第一次专利法的修改，国家知识产权局在1993年颁布了新的《专利审查指南》以技术效果和技术方案作为审查计算机软件是否具有专利性的关键标，相对于1985年的第一部审查标准明显比较宽松，与当时的国际主流标准基本一致，我国后来的几次专利审查指南的修改也基本沿袭了这个标准。 在我国，放宽计算机软件专利审查标准也是一个基本的变化趋势，但是，在专利法的条文中，仍然没有关于软件可专利性的规定。目前，我国还不承认计算机软件本身的专利性，软件与智力活动的规则和方法的区分标准还未明确，这些问题的存在势必影响软件的保护力度和软件产业的健康发展。本论文的主旨就在于通过比较的方式，论证计算机软件的可专利性，以及对其加强专利保护的必要性。 笔者最关注的是我国软件保护制度的发展，不得不承认，我国相关的软件立法以及司法实践明显的受到了西方软件发达国家立法进程的影响。虽然在全球经济一体化的时代背景下，中国的软件立法不可能脱离世界，但无论如何我们不能简单的照搬其他国家的立法，因为，我国软件产业的发展有自己的特点，盲目吸收必然会造成法律适用的困难。 目前，我国的软件法律保护制度还不完善，一些规定还需要进一步解释或者细化。对于计算机软件的专利保护程度和审查标准，笔者认为我国应该在保持司法独立的基础上，以保护好我国的软件产业为基本宗旨，从我国软件行业发展的实际情况出发，针对软件本身的特殊性，认真进行调研，经过相关各界广泛讨论之后确定，以保证我国软件产业的健康发展，这也是本论文选题的意义所在。在文章最后针对如何完善我国计算机软件的专利保护制度，笔者提出了自己的几点建议。

How to give more appropriate legal protection to computer software is a global issue. Because of the special attribute of computer software, it can be the object of patent, copyright and trade secret protection, but the software has long been protected in most countries as the object of the copyright law, rather than Patent law. Owing to the development and changes of recent decades, the United States, European Union, Japan and other developed countries and regions have liberalized patent protection limitations of computer software in varied degrees, granted patent right to computer software through the relevant legislation or judicial precedents. Currently, patent protection of computersoftware is being accepted in most countries, our country's old patent examination on computer software is very strict, a computer program only to make hardware devices emerge creative technology improvements can be Granted patents，the software only as an adjunct of hardware, software itself is not patentable in any case. In order to adapt to the first recension of patent law, the State Intellectual Property Office issued a new patent examination guidelines in1993, the revised patent examination guidelines use technology effect and technology scheme to determine whether to grant patent right, which is adaptive to theu international mainstream standards, and More liberal than old examining standard, and later several recensions to the patent examination guidelines are basically followed this standard. In China, loosening restrictions to patent examination standard of computer software is a basic trend, however, there is a lack of provision about the patentability of software in the patent law. at present, we does not recognize the patentability of computer software itself, and the scope of the software patent is still unclear, these problems will certainly affect the protection of software and the healthy development of software industry. The purpose of this paper is demonstrating the patentability of computer software and strengthening the necessity of patent protection to it. I am most concerned about our country's development of software protection regulations, we have to admit that our country's relevant legislation and judicial practice are obviously affected by the Western countries and regions. In the background of global economic integration, Our software protection mode should accord with the world trend, but in any case we can not simply learn from other countries. Because the development of China's software industry has its own characteristics, the blind absorption of the foreign law will definitely lead to problems of application At present, our country's legal protection system of software is still not perfect, some provisions need to be further explained or detailed, for the degree and examining standard of patent protection for computer software, I believe that China should remain the basis of judicial independence, follow the specificity of the software itself, launch in-depth research and extensive discussions.Based on this, I give proposals to improve our country's patent protection system of computer software at the end of the paper.
