Why would one ever do this as a requirement for patentability is that it doesn't exist as prior art?

#32...I think the actual patent is on moving the cache snooping into the interconnect?
I think all of the figures presented are part of Intel's claim that any processor that implements cache snooping in the interconnect are subject to this patent.

#33Well... AMD can just cite their presentation as prior art, and it will be struck down. If anything, Intel was foolish to waste money on bored lawyers.
Not how it works, actually. The system changed in 2013 and now whoever is first to file gets the patent, even if someone else can demonstrate prior art. https://www.justia.com/intellectual-property/patents/first-t... AMD should have filed their own patents before talking about it publicly - that's how the game is now played. If you don't - it's now possible for someone else to file a patent on your own invention.
They can, but if it is based on industrial espionage, outright theft or plagiarism then that would definitely be a reason for them to lose the patent.

#34Remember the advice of "How to read a patent in 60 seconds" [0]. In this case there are two very short independent claims (1 and 3), all the way at the last page. They both seem to just be talking of some specifics on cache coherency.

#36So... Would the patent claim be a copyright infringement of AMDs presentation?
AMD could invalidate it as prior art pretty easily.
How so? The claims have very little to do with the diagrams. They are only there as an example processor for the claims being presented. The claims are specifically about cache. More specifically clearing/invalidation. What better way to prevent the competition from implementing something similar than using the competitions architecture as the base to show how it could be implemented? It is Intel's prior art against AMD.

#38USPTO will actually search for this kind of thing (assuming the situation is as-described, which I suspect is not assured). Source: this happened to me -- I wrote an internal doc describing a new product feature. That doc was used both our product documentation team has the basis for user documentation; and by our patent team as the basis for a patent application. When the patent was reviewed, the examiner found the user doc on the internet and rejected the application due to prior art. We had to prove to the USPTO that both were derived from an older doc (by finding the older doc with timestamp and sending it to them with associated legal knobs and whistles).

If you don't believe data presented by the guy who was editor for Anandtech for how many years, that's on you.
To be fair not everyone knows who @IanCutress is. The profile description of "Consultant, Chief Analyst, Influencer." doesn't really indicate he's a subject matter expert.

#40That's how the US patent system works now. "The first inventor to file (FITF) provision of the America Invents Act transitions the U.S. to a first-inventor-to-file system from a first-to-invent system and became effective on March 16, 2013" https://www.uspto.gov/patents/first-inventor-file-fitf-resou...
To be clear, first-to-file just means that in the event that the patent is granted, it's awarded to the person who filed first instead of the "actual" inventor. However, the patent can still be invalidated for prior art. The net effect of this is that AMD lost their ability to patent their invention by not filing first.
Perhaps this was the entire point of Intel's work here??? Worst case scenario for Intel they block AMD from patenting (and allowing Intel to use it).
