Office Action

§103
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 . Claim Rejections - 35 USC § 103 2. 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 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. 3. Claims 1 – 20 are rejected under 35 U.S.C. 103 as being unpatentable over Kumar et al. (US Publication Number 2016/0335196, hereinafter “Kumar”) in view of Fraction (US Patent Number 11,618,592). 4. As per claims 1, 10, and 13, Kumar teaches an electronic device, system and method adapted to implementing a communication comprising a first memory (OTP 140, figure 1) adapted to storing first software adapted to initializing the communication (first software consists of firmware installed by the manufacturer for initialization of the device, paragraph 11), the first software being different from second software adapted to implementing the communication (the second software is that store in the static memory 150 comprised of commands used for communication, paragraph 13). Kumar does not appear to explicitly disclose the structure of the preamble where communication is by means of a serializer/deserializer. However, Kumar discloses communication by means of a serializer/deserializer (column 7, lines 29 and 44). Kumar and Fraction are analogous art because they are from the same field of endeavor. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, having the teachings of Kumar and Fraction before him or her, to modify the communication mechanism of Kumar to include the configuration of Fraction because it would enhance robustness of memory functionality. One of ordinary skill would be motivated to make such modification in order to enhance integration functionality (column 1, lines 60 – 67). Therefore, it would have been obvious to combine Fraction with Kumar to obtain the invention as specified in the instant claims. 5. Kumar modified by the teachings of Fraction as seen in claim 1 above, as per claims 2 and 14, Kumar teaches a device and method, wherein the first memory is a programmable read-only memory (OTP memory, figure 1, paragraph 10). 6. Kumar modified by the teachings of Fraction as seen in claim 1 above, as per claims 3 and 15, Kumar teaches a device and method, wherein the first software is an abbreviated version of the second software (the first software contains linking information for the second more robust software, paragraphs 11 and 12). 7. Kumar modified by the teachings of Fraction as seen in claim 1 above, as per claims 4 and 16, Kumar teaches a device and method, wherein, once the first software has been used, the electronic device is adapted to receiving the second software (software in OTP is used for initialization and software in static memory is used for functionality for commands, paragraphs 12 and 13). 8. Kumar modified by the teachings of Fraction as seen in claim 1 above, as per claims 5 and 17, Kumar teaches a device and method, wherein the second software is sent by a first control circuit external to the electronic device (static memory seen to receive external commands via 110, figure 1, paragraph 21). 9. Kumar modified by the teachings of Fraction as seen in claim 1 above, as per claims 6 and 18, Kumar teaches a device and method, wherein the second software is stored in a second memory of the electronic device (static memory 150, figure 1 and 606, figure 6). 10. Kumar modified by the teachings of Fraction as seen in claim 1 above, as per claim 7, Fraction teaches a device, wherein the second memory is a static random-access memory (SRAM 104, figure 1) of a serializer/deserializer module of the electronic device. 11. Kumar modified by the teachings of Fraction as seen in claim 1 above, as per claim 8, Kumar teaches a device, wherein the first software is adapted to initializing the communication having a first data rate lower than a second data rate of the communication when it is implemented by the second software (OTP and first software speed is lower than that of SRAM and second software, paragraphs 11 – 13, figure 1). 12. Kumar modified by the teachings of Fraction as seen in claim 1 above, as per claim 8, Kumar teaches a device, wherein the first software is adapted to initializing the communication having first functionalities different from second functionalities of the communication when it is implemented by the second software (first and second software have different functionality where SRAM is utilized to avoid filling OTP from manufacturer to enhance streamlining, paragraphs 11 – 13). 13. Kumar modified by the teachings of Fraction as seen in claim 1 above, as per claims 11 and 19, Kumar teaches a device and method, wherein the first software and the second software are microcodes adapted to directly send commands to one or more electronic circuits and components responsible for implementing a communication by serializer/deserializer (sent to 130 virtual OTP memory manager component, figure 1). 14. Kumar modified by the teachings of Fraction as seen in claim 1 above, as per claims 12 and 20, Fraction teaches a device and method, wherein initialization of the communication corresponds to triggering of one or more electronic circuits and components responsible for implementing a communication by serializer/deserializer (boot code processing in slower memory allows for SERDES handling in SRAM, column 7, lines 26 – 46). Conclusion 15. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. ATTa/Garnett/Gueller/Lee/Lu/Mirzaei/Moschopoulos/Park/Shi have teachings of two memories utilized first one being for boot/initialization and second for operating software for communication.
