I think of it as the 'age filter'.
I tend to agree. However, I myself have not read the actual patent, only synopsis of the patent by various people. But, from the synopsis, and the hints dropped by various experts, particularly at the recent SES conference, it sounds like an age filter to me.
But, I'm pretty sure it's a fairly loose age filter. A new domain that gets good links from an older relevant domain can show up in pretty much the same amount of time that it would have three years ago, before the new patent. (as has been stated in this forum before)
But, if a new domain doesn't get the right type of links, maybe it is "sandboxed". ( age filtered )
I really don't know. I haven't tested it.
I like the idea of an age filter to stop spam. I'm not sure how well it's working, tho.
