Duplicate Content for Product Descriptions

[mjhonson]

If yo do want the content in-page and are worried that it may cause some sort of duplication issue, then you could have it dynamically loaded in JavaScript.

I personally think Google is clever enough to realize it's common content and treat it appropriately. Just like it does with headers, footers and sidebars.
Does anyone  have clever suggestions?

eCommerce websites should have  their own product descriptions if they can manage it (it will be beneficial for their SERPs rankings) but the ones who cannot won't be penalized by having the same product descriptions (or part of the same descriptions) if it is only a "small" part of their content (user reviews, similar products, etc).
