In temporary: There are numerous examples of applied sciences that the patent holder might by no means transfer past the design desk. There are maybe much more filed simply to stop rivals from patenting one thing an organization may work on sooner or later. However, as a latest Intel patent illustrates, there are additionally some patents full of plagiarized content material.
On Wednesday, a Twitter consumer going by Underfox revealed an interesting-looking patent lately awarded to Intel. Underfox suspects the patent could also be associated to Intel’s Ocean Cove CPU structure, which is anticipated to be the successor of the Golden Cove structure used within the efficiency cores of twelfth technology Alder Lake processor designs.

More importantly, a superficial inspection reveals it comprises blocks of textual content and diagrams that look strikingly much like these used to explain AMD’s Zen processor structure throughout a presentation on the Hot Chips 28 occasion in 2016. So it seems as if Intel utilized for a patent for AMD’s tech in August 2018 when it submitted the appliance.
However, upon nearer inspection, the 122-page doc describes a number of architectural options of x86 and Arm CPUs, GPUs, RISC-V, and extra. Hardware analyst and former AnandTech senior editor Dr. Ian Cutress notes that it’s largely help supplies for a generic CPU structure that Intel wished to explain within the patent — a technique to clear a cache line that is not vulnerable to side-channel assaults of the Spectre selection.
Yeah, that is positively:
(a) An intern’s summer time mission to ‘describe how a CPU works’
(b) Said intern took generic CPU arch slides from web, and ended up with AMD
(c) Actual patent covers some minor factor to do with safety and monitoring
(d) 122 pages.

Interestingly, the doc cites an article written by Dr. Cutress again in 2016 and makes use of black-and-white variations of the AMD slides mentioned in his evaluation of the first-generation Zen structure. Intel and AMD have a cross-licensing settlement signed in 2009 that stops the 2 corporations from suing one another for patent infringement, however this does not apply to the doc in query.
It seems to be a case of a poorly-designed patent doc with plagiarized content material. Intel would not declare to have invented AMD’s Zen microarchitecture, however reasonably the precise patented tech is buried in copy-pasted content material. The amateurish job has invited hypothesis that Intel produced this patent with malicious intent, however we now have but to see proof to help this. If something, it seems like Intel has been engaged on methods to enhance the safety of its processors, despite the fact that it (formally) believes its designs are safe sufficient as they’re.
