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 § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis ( i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale , or otherwise available to the public before the effective filing date of the claimed invention. Clai ms 1-20 are rejected under 35 U.S.C. 102 (a)(1) as being anticipated by Eilert (20050010725) Regarding Claim 1, in Fig s . 1 and 2 and paragraphs 0005, 0017 and 0028, Eilert discloses an apparatus comprising: a die stack 104/106 ; and a plurality of signals 116 arranged across the die stack, wherein the plurality of signals are manipulated to form a unique identifier for each die included in the die stack (see paragraphs 0017 and 0025) . Regarding Claim 2, in Eilert, the plurality of signals comprise a plurality of immutable binary signals that are manipulated at least in part by swizzling to form the unique identifier for each die included in the die stack. Regarding Claim 3, in Eilert, wherein the unique identifiers comprise: a first unique identifier for a first die included in the die stack, the first unique identifier being formed by a first pattern of the plurality of signals; and a second unique identifier for a second die included in the die stack, the second unique identifier being formed by a second pattern of the plurality of signals. Regarding Claim 4, in Eilert, the plurality of signals are manipulated at least in part by digital logic to form the unique identifier for each die included in the die stack. Regarding Claim 5, in Eilert, the unique identifiers collectively amount to a number that is at least twice as high as a total number of signals included in the plurality of signals. Regarding Claim 6, in Eilert, the digital logic comprises at least one of: a linear-feedback shift register; a digital adder; or a digital subtractor. Regarding Claim 7, in Eilert, the plurality of signals comprises: a first signal that is shifted in one direction relative to a certain sequence between a first die and a second die included in the die stack; and second and third signals that are shifted in another direction opposite the one direction between the first die and the second die. Regarding Claim 8, in Eilerts, wherein: the certain sequence comprises a first position, a second position, and a third position aligned across the die stack; and the plurality of signals comprises: a first signal coupled to the first position on the first die; a second signal coupled to the second position on the first die; and a third signal coupled to the third position on the first die. Regarding Claim 9, in Eilert, the first signal is shifted to a final position in the certain sequence on the second die; the second signal is shifted to the first position on the second die; and the third signal is shifted to the second position on the second die. Regarding Claim 10, in Eilert, the final position in the certain sequence is the third position. Regarding Claim 11, in Eilert, the plurality of signals comprises a fourth signal that is coupled to a fourth position in the certain sequence on the first die and is shifted to the third position on the second die. Regarding Claim 12, in Eilert, the first signal is shifted to the third position on a third die included in the die stack; the second signal is shifted to the final position on the third die; the third signal is shifted to the first position on the third die; and the fourth signal is shifted to the second position on the third die. Regarding Claim 13, in Eilert the first signal is shifted to the second position on a fourth die included in the die stack; the second signal is shifted to the third position on the fourth die; the third signal is shifted to the final position on the fourth die; and the fourth signal is shifted to the first position on the fourth die. Regarding Claim 14, in Eilert, wherein the first die, the second die, the third die, and the fourth die are duplicates of one another. Regarding Claim 15, in Eilert, the certain sequence is arranged at a specific location relative to the first die; and the certain sequence is arranged at the specific location relative to the second die. Regarding Claim 16, in Eilert, a base die that is coupled to the die stack, wherein a number of dies included in the die stack corresponds to a number of signals included in the plurality of signals. Regarding Claim 17, in Eilert, Figs 1 and 2 and in paragraphs 0005, 0017 and 0028, a base die; a die stack; and a plurality of signals arranged across the die stack, wherein the plurality of signals are manipulated to form a unique identifier for each die included in the die stack. Regarding Claim 18, in Eilert, the plurality of signals comprise a plurality of immutable binary signals that are manipulated at least in part by swizzling to form the unique identifier for each die included in the die stack. Regarding Claim 19, in Eilert, the plurality of signals are manipulated at least in part by digital logic to form the unique identifier for each die included in the die stack. Regarding Claim 20, in Figs 1 and 2 and paragraphs 0005, 0017 and 0028, Eilert discloses coupling a base die to a die stack; arranging a plurality of signals across the die stack; and manipulating the plurality of signals to form a unique identifier for each die included in the die stack. Examiner is including Nakanishi 20140241022 (Fig. 7, paragraphs 0063 and 0064) , Johson 2010031684, paragraphs 0028, 0030 and 0037 , Funaba (20050082664) paragraphs 0031 and 0064, Vandebriel (20190165791) (paragraph 0003) as pertinent prior art references that are not relied upon on this rejection but that do disclose uniquely identifying individual dies on a stacked die configuration.
