DETAILED ACTION
Notice of Pre-AIA or AIA Status
1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
2. Claims 28–47 are presented for examination in PCT international application filed on 03/26/2021 (PCT/CN2021/083178), and entered the national stage on 09/20/2023.
Claims 1–27 are cancelled.
Drawings
3. The drawings were received on 09/20/2023 (upon national stage entry). These drawings are acceptable.
Claim Objections
4. Claim 38 is objected to because of the following informalities:
Claim 38 appear to be dependent from claim 37 (as opposed to the currently recited claim 10 which is cancelled.).
For purposes of examination, they will be construed to be dependent upon claim 37.
APPROPRIATE CORRECTION ARE REQUIRED.
Claim Rejections - 35 USC § 101 (Computer Medium)
35 U.S.C. 101 reads as follows:
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
5. Claims 46–47 are rejected under 35 U.S.C. 101 because it is directed to non-statutory subject matter and thus do not fall within at least one of the four categories of patent eligible subject matter.
6. As to claims 46–47, they are directed to a “machine-readable medium having program code executed thereon.”
Under current Office examination procedure, and absent clear definition or exclusion by the Applicant to the contrary, the broadest reasonable interpretation of a machine-readable medium can encompass non-statutory, transitory forms of signal transmission, such as a propagating electrical or electromagnetic signal per se. See MPEP § 2106.03, Eligibility Step 1: The Four Categories of Statutory Subject Matter.
(see Applicant’s Specification, paragraph 192: “Such electronic devices store and communicate (internally and/or with other electronic devices over a network) code and data using computer machine-readable media, such as non-transitory computer machine-readable storage media ( e.g., magnetic disks; optical disks; random access memory; read only memory; flash memory devices; phase-change memory) and transitory computer machine-readable communication media (e.g., electrical, optical, acoustical or other form of propagated signals-such as carrier waves, infrared signals, digital signals, etc.” — which describes a type of “machine-readable” media as transitory).
Accordingly, the claimed “machine-readable medium” is directed to non-statutory subject matter.
Applicant is advised to amend this portion of the claim to recite a “non-transitory machine-readable medium” to overcome the 101 rejection.
Allowable Subject Matter
7. Claims 28–45 are allowed.
Claims 46–47 would be allowable if rewritten to overcome the applied 101 rejections set forth in this action.
The following is the Examiner’s statement of reasons for allowance:
The prior art of record, when viewed individually or in combination, does not expressly teach nor render obvious the features of independent claims 28, 37, and 46 when viewed as a whole, specific to the limitation(s) of:
“accessing, by the IOMMU, an entry in a first translation table using at least the first address space identifier to determine that the memory access request is directed to the first private memory region which is not directly accessible to the IOMMU,
generating, by the IOMMU, an address translation request associated with the memory access request,
wherein based on the address translation request, a virtual machine monitor (VMM) running on one or more of the plurality of cores is to initiate a secure transaction sequence with trust domain manager to cause a secure entry into the first trust domain to translate the GVA to a physical address based on the address space identifier.”
