Contact your lawyers, and register your copyrights before they steal from you. Then after that fact sue them (not the employee who has no money, but the who buy the component), which allows you to collect tripple damanges. You end up making more if they steal your code than you can selling it yourself. Contact a lawyer though, because what I said only applies in narrow cases, you need a lawyer to tell you the specifics. In general I wouldn't worry about it. Most components are specific enough they have no use to anyone outside your company. When they are of use, there is normally a standard componant that is good enough, and if combined with the expirence of all the coders who are using them better.
