If she hasn't already, the owner/designer of the pattern needs to fill out a VeRO form with eBay, and they'll shut down any copycats in a heartbeat.
Here's a link describing the VeRO program:

And here's a link to the form she'll need to fill out:
http://pages.ebay.com/vero/notice.html
If you'd like to pass this information along to her, that'll be great. :)
Sometimes it's harder for a "regular" eBayer to get eBay's attention regarding copyright infringement, but from my experience, once the copyright owner steps up and fills out the VeRO form, they'll shut down the listings so fast the seller's head will be spinning. ;-)
