No, it means if you make noise, your bogus patent gets the approval. Then a bunch of poor suckers get to spend everything they have in court reversing the bad decision.
That kinda goes against your whole "they rubber stamp patents blindly" rant earlier, then.
Keep in mind, the rejections include a big pile of some idiot patenting something that came and went before he was born but he's totally convinced nobody ever thought of it before because he packs the bearings with cat hair plus the ones that are just a vague thought with no reduction to practice at all. That and a pile of zero point energy anti-gravity whoosiewhatsises.
If not, how do you explain this?
I explain that as Slashdot's usual practice of paraphrasing an invention by describing it in known terms, forgetting that 10 seconds ago they just paraphrased the invention, and angrily complaining that the known terms are the invention and that therefore it's old. An article about a patent on the transmission of the Tesla Roadster would probably be "Inventor claims to have patented the Model T plus AA batteries! USPTO insane!"
In your example, the patent claim is:
1. A computer-implemented method comprising:
selecting a file having a path name in a distributed file system, wherein the file is divided into a plurality of chunks that are distributed among a plurality of servers, wherein each chunk has a modification time indicating when the chunk was last modified, and wherein at least two of the modification times are different;
identifying a user profile associated with the file;
determining a memory space storage quota usage for the user profile;
deriving a file time to live for the file from the path name;
determining a weighted file time to live for the file by reducing the file time to live by an offset, where the offset is determined by multiplying the file time to live by a percentage of memory space storage quota used by the user profile;
selecting a latest modification time from the modification times of the plurality of chunks;
determining that an elapsed time based on the latest modification time is equal to or exceeds the weighted file time to live; and
deleting all of the chunks of the file responsive to the determining.
Without needing to go into all of the ways it's different from a simple "expiration date" metadata field, we can simply look at the first step - the file is divided into a bunch of chunks, and they have different modification times. Under the old system, do you delete some of the chunks before deleting others, because they weren't modified? That's bad. There's also that whole weighted file time to live based on storage quotas. Expiration date metadata doesn't even touch that.
So, how do I explain it? Bad Slashdot article, and the patent is certainly valid over what the article thinks is anticipatory prior art. Maybe there's other art out there, but that one sure as shiat ain't it.
