很多软件侵权案件需要对原、被告的程序进行技术鉴定。在简单的原样拷贝的情况下,可直接对目标程序进行比较;但如果被告对源程序做了改动,那怕是少量的改动,都会引起目标代码大段大段地变化与错位。而由于目标代码难以阅读,代码改变及错位后往往难以区分究竟是“实质性”差异还是“表面”的差异。因此,不少法院和鉴定专家要求当事人必须提供软件的源代码,否则即认为证据不足,或者不具备鉴定条件,不能得出鉴定结论。我们知道,软件的源程序企业一般都是保密的,上市销售的是软件的目标程序,多数情况下,权利人很难获得被告的源程序。这就使得相当一部分权利人的权益得不到司法救济。
A lot of software infringement cases need technical appraisal of the original and defendant's procedures. In the case of a simple copy of the original, the target program can be compared directly; but if the defendant made changes to the source code, even a small amount of changes will cause the target code to change and dislocate large sections. However, since the target code is hard to read, it is often hard to distinguish whether the difference is “substantial” or “superficial” after code changes and misplaced. Therefore, many courts and accreditation experts require the parties to provide the source code of the software. Otherwise, they think that the evidence is not sufficient, or they do not have the qualification conditions and can not reach the conclusion of appraisal. We know that the source software companies are generally confidential, the market is the target software program, in most cases, the rights of people is difficult to obtain the source of the defendant. This makes a considerable part of the rights of rights holders without judicial relief.
