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 . Election/Restrictions Claims 11-20 is withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 6/23/26. The office hereby notes that claims 11-20 are herein deemed as non-elected, whereas the claim construction(s) which define different specie(s) thereof relative to the elected claims which do not require the workload controller has instructions stored thereon (in which storing instructions may otherwise be accomplished by a separate storage device; whereas a workload controller alone does not necessitate storing instructions); select a threshold voltage from a plurality of processor cores, changing a thermal mass of a working fluid and/or to select a computing component of a plurality of computing components. 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. Regarding Claim 1; “a workload controller in data communication with the refrigeration system” in line 10 is unclear; whereas sufficient structure has not been asserted to accomplish the each associated function, as asserted. The office herein notes that the claim only previously “a refrigeration system” in lin 8 without presenting or limiting the system to any particular type which necessitates data storage or data communication and/or any structure which sends/receives data signals etc, to accomplish data communication with a workload controller and thus the assertion reads on more than one plausible claim construction which read on different inventive structures. Further, “a refrigeration system” in line 8 is unclear; whereas line 5 already asserts a refrigeration system, and thus it cannot be readily ascertained if deemed to refer back to the same refrigeration system or additional denote a second refrigeration system. Going further, “a conduit having a flow direction and configured to receive heat from the processor core and the memory device a refrigeration system in series” is unclear; whereas the underlined portion either has grammatical omissions or omits intended structure or coupling therebetween, and thus it cannot be readily ascertained if the processor core and the memory device are intended as parts of a refrigeration system or if each of a processor core, a memory device and a refrigeration system are deemed as three separate features. Regarding Claim 10; “a second refrigeration system” is asserted without respect to either refrigeration system already asserted in claim 1 lines 5 and 8. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US 20150062804 A1 Campbell; Levi A. et al.
