Office Action

§112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-20 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. The claims recite migrating “data stored in the first zone”. The claims need to clarify which “first zone” they are referring to. Examiner’s Note The closest prior art of record, “Franceschini” discloses flash device write in figure 1. Claims 1-20 may be allowable if the 112 issue is fixed. The primary reasons for allowance of claim 1 in the instant application is the combination with the inclusion in these claims that “plurality of memory blocks configured in the first memory area with a write speed and a read speed that are faster than a write speed and a read speed of the plurality of memory blocks in the second memory area; and a controller configured to set a first zone to store cold data in the first memory area when the controller receives a first write booster type from a host; set the first zone to store cold data in the second memory area when the controller receives a second write booster type from the host; set a second zone in the second memory area; and migrate cold data stored in the first zone to the second zone when the first memory area is full”. The prior art of record neither anticipates nor renders obvious the above recited combination. The primary reasons for allowance of claim 11 in the instant application is the combination with the inclusion in these claims that “a plurality of memory blocks configured in the first memory area with a write speed and a read speed that are faster than a write speed and a read speed of the plurality of memory blocks in the second memory area; setting a first zone to store cold data in the first memory area when a controller receives a first write booster type from a host; setting the first zone to store cold data in the second memory area when the controller receives a second write booster type from the host; setting a second zone in the second memory area; and migrating cold data stored in the first zone to the second zone when the first memory area is full”. The prior art of record neither anticipates nor renders obvious the above recited combination. The primary reasons for allowance of claim 20 in the instant application is the combination with the inclusion in these claims that “a plurality of memory blocks configured in the first memory area with a write speed and a read speed that are faster than a write speed and a read speed of the plurality of memory blocks in the second memory area; and a controller configured to set a first zone to store cold data in the first memory area when the controller receives a first write booster type from a host; set the first zone to store cold data in the second memory area when the controller receives a second write booster type from the host; set a second zone and a third zone in the second memory area; store hot or warm data in the second zone; and migrate data stored in the first zone to the third zone when the first memory area is full”. The prior art of record neither anticipates nor renders obvious the above recited combination. As allowable subject matter has been indicated, applicant's response must either comply with all formal requirements or specifically traverse each requirement not complied with. See 37 C.F.R. § 1.111(b) and § 707.07(a) of the MPEP.
