Tracking patent submissions via RSS

Via GNC and Scoble, we have PatentMojo - RSS feeds for patent submissions. I found it quite interesting that big pharma is in their demo list (with software and telecomm) - reasonable target markets, but a more interesting patent watch would be against biotech. Also, their selection of 5 companies was probably by brand recognition - what about JNJ (#2 in market cap), or ABT (#5 in market cap)? Ok, AMGN is #2 in biotech, what about good 'ol DNA? Monitoring patent action on all the biotechs is probably fascinating reading - that site/service is actually pretty dynamite stuff!
