legal question:
I have a client with a content engine that he wants modified. the content engine was developed by another company, he says he has purchased the engine but no longer wants to use that company for $$ reasons.

can I modify (add components) the content engine or is that infrenging on the copyright of the original creator?

example he wanted the database expanded, and new functions added, he also wants to remove all the references to the company that designed it, ie: remove footer with link to original creators site.

Gasolene, This is a question that should be asked of an attorney. Unless someone here is an attorney, or has gone through this exact same thing, you'll not be garanteed acurate advice.

I suggest you read the terms and conditions set forth by the company your client originally purchased the script from. There are many different types of licenses companies issue, such as GNU GPL and other open source licenses which would most likely allow you to modify the code. However, there are many companies that issue licenses that would not permit you to modify the code in any way.

Here are many types of licenses that are commonly used by software companies:

I would concur with BigWeb that it depends on the license under which the software was modified...

However, if they have paid for a license for the software, I'm sure the "fair use" section of the Copyright laws allows them to modify it for their own personal use at least, although they can't re-release/resell it (unless it's under a compatible license, such as the GPL - although original copyright notices would still have to be held in place, even in this case).
