摘要：证据保全是指在诉讼前或诉讼中，由法院或公证机关对可能灭失或以后难以取得的证据及时加以收集，固定和保护的法律制度。由于知识产权侵权诉讼证据本身具有隐蔽性、易毁性、不稳定性等特点，较之普通的民事诉讼证据更难以取得和容易灭失，故在知识产权侵权诉讼中证据保全尤为重要。而近年来，当事人申请证据保全的知识产权侵权案件数量呈逐年上升趋势，充分分析和把握现有制度，立足不同类型知识产权的特点解决证据保全过程中存在的问题成为提高知识产权侵权案件审判质量和效率的重要一环。

Abstract：The preservation of evidences refers to the collection, settlement and protection of evidences which are apt to vanish or will be hard to collect later by the court or notary public office before or during the relevant lawsuits. As the evidences in intellectual property lawsuits of infringement are unobvious, unstable and fragile, they are easier to vanish and hander to collect. So the preservation of evidences is more important in intellectual property lawsuits of infringement than common civil lawsuits. In recently years, the number of applications by parties in intellectual property lawsuits of infringement for preservation of evidences increases year by year. As a result, it plays an important role in improving the quality and efficiency of intellectual property judicial procedures to make sufficient analysis of the current system, and solve relevant problems.
