I came across this post tonight which would lead you to believe so. It will be interesting to see how this plays out.
Here’s an image from the patent filed:
Here’s a snip from the post at All Facebook
On Tuesday, Facebook was awarded a major patent for “Dynamically providing a news feed about a user of a social network”. This is a huge deal for a number of reasons, most significantly that it grants Facebook the opportunity to pursue other social networks which are infringing on their patent. Included in the patent are additional claims including feed filters, feed advertising, searching the feed, and more. (update We’ve been told that this is about the implicit feed stories. Will update when we have more info.)

Update: there’s a much more detailed post on ReadWriteWeb here with a good discussion on it here. Thanks to Mahendra Palsule for the tip.

So just don't call you facebook style activity feed and activity feed.
Still. This is mighty despicable of them.
We believe we may have some measure of prior art at Nature Network with launched something like implicit activity feeds two months before Facebook.
