Duplicate content problem?

[sanamonteiro]

There should be no duplicate content with in website otherwise PR will be very low in search engine's result. Content should be different and unique.No duplications will be there in our website.

Its bad.. you should add some unique content in there to make it unique than the other products.

All of the content is unique. The problem is the duplicate content is showing from our old website. It was at www.widgets.com/325235235 now it redirects to www.widgets.com/itemname. It is a 301 redirect so it shows that it has been permanently moved, but still shows as a duplicate. It dropped the last few weeks on a regular basis but I come in today and it is right back to where it was a month ago. Any more ideas?
