The Rethinkers have more blogs than you could shake a stick at. Seriously...
One of them is called the "RSS Mojo" blog. What is it?
RSS Mojo currently has two components: (1) US Patent and Trademark Office News and (2) IP Lawsuit Filing Updates.1. US Patent and Trademark Office News
Unlike the Copyright Office, the Patent and Trademark Office doesn't yet have RSS feeds of their News & Notice's page. We've done it for you. You can subscribe via RSS or via e-mail.
2. Lawsuit Filings
We also provide regular updates of recently filed patent, trademark and copyright lawsuits. They are currently provided for free, but will move to a weekly (subscription only) and monthly (free) model in the next few months. You can subscribe via RSS or E-mail.
