Google Patents Staple of '70s Mainframe Computing
theodp writes "'The lack of interest, the disdain for history is what makes computing not-quite-a-field,' Alan Kay once lamented. And so it should come as no surprise that the USPTO granted Google a patent Tuesday for the Automatic Deletion of Temporary Files, perhaps unaware that the search giant's claimed invention is essentially a somewhat kludgy variation on file expiration processing, a staple of circa-1970 IBM mainframe computing and subsequent disk management software. From Google's 2013 patent: 'A path name for a file system directory can be "C:temp\12-1-1999\" to indicate that files contained within the file system directory will expire on Dec. 1, 1999.' From Judith Rattenbury's 1971 Introduction to the IBM 360 computer and OS/JCL: 'EXPDT=70365 With this expiration date specified, the data set will not be scratched or overwritten without special operator action until the 365th day of 1970.' Hey, things are new if you've never seen them before!"
Here is the crux of the first claim: "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."
Can we please have an end to the stupid articles where someone intentionally mis-interprets the abstract or even just the title of a patent and pretends it's some simple thing that's been done for decades to try to drum up anti-patent sentiment? There seems to be one a week or so.
E pluribus unum
If you actually read the patent, it is specifically for a similar method, but designed for Distributed File Systems.
Ahhhh... that's good.
You see, I was scared shitless that we are still quibbling over patents granted with the only claimed difference over some old methods (patented or not) being "on a computer".
I see now how wrong I was: we stepped in the glorious era of the "in the cloud" claims.
Questions raise, answers kill. Raise questions to stay alive.
It's still a dumb patent; a trivial weighting addition doesn't change this. I mean, seriously, that's less complicated than your average photoshop filter, and it's an obvious "innovation" that any engineer would think up if they were to be asked to implement file expiration on Google's platforms.
For every problem, there is at least one solution that is simple, neat, and wrong.
Yes; maybe; and the whole summary is stupid. From claim one of the patent; the very first paragraph:
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
So; where the mainframes of the 70s had single consolidated disks stores this is talking about doing this on a distributed filesystem. The area of application is indeed new completely opposite to the claim of the summary.
Patents are not supposed to control what you do; instead they control how you do it. Since the way that Google is claiming to do this is by going around comparing the timestamps on a bunch of different distributed chunks of a file, this is something that no mainframe of the 70s is likely to have had to to so it may even be a new way to automatically delete temporary files. I wish people would begin to understand this and commenters would point it out every time. I wonder if this isn't a bunch of patent lawyers trying to make us look silly.
Having said that; If you had a distributed file which kept a timestamp on each of several separate chunks, how would you go about deciding when to automatically delete it? My guess is that the solution you would come up with quickly is basically the one in the patent. You certainly wouldn't have great difficulty in deciding how you do it; suddenly think "maybe there's a patent that might tell me how to do this"; go to the patent office and read the patent then come back inspired and manage to solve your problem only because Google was so nice as to publish their solution. Patents are supposed to record valuable secrets that companies might otherwise keep to themselves in a way that helps humanity. This one is failing at that.
What this comes down to is that the whole idea of patents on things as abstract as software is stupid and is an illegal interference in free speech a right everyone should have under the universal declaration of human rights. The patent officers of the USPTO and the congressmen who put them there should be arrested.

The USPTO is supposed to support itself with fees. The largest fee is for reexamination, creating a financial incentive to grant bad patents (which are likely to be reexamined). -da
