Patenting 'Invited Pull'

talon sent us this link talking about a small company's attempt to get 'invited pull' patented. What this means is that the tech that Netcaster, Backweb, Channels etc etc would all fall under this patent, and that the companies involved would be liable to pay money to the company in question, which has patented "Netdelivery". The patent was issued August 4, making me wonder about the timing, and how many of the "62 companies" have knowingly infringed upon their patent.
