It’s been a busy week in the world of patents and lawsuits:

Facebook patents the newsfeed:  http://mashable.com/2010/02/25/facebook-news-feed-patent/

Google patents location based ads:  http://digital.venturebeat.com/2010/03/01/google-location-ads/

Apple suing HTC + Google over patent infringement:  http://techcrunch.com/2010/03/02/google-htc-apple-lawsuit/, http://techcrunch.com/2010/03/02/the-complaint-apples-patent-lawsuit-against-htc-is-all-about-android/

So are these warranted?  Bluffs?  Encouraging or stifling innovation?  Chime on in…
