The way I understand this issue, if a pattern has a copyright, you cannot sell a finished product from the pattern legally. I know the larger and even some of the smaller pattern companies specifically state you cannot produce their product for sale.
I've done a little research on this issue, and from what I read, you cannot just add a ruffle or some minor adjustment and call that pattern your own. The exact wording I remember was that your "creation" cannot be recognizable as the pattern you used if it is a copyrighted pattern.
Hope this helps
