Office Action

§112
DETAILED ACTION 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 2-3 and 12-13 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. Claims 2 and 12 recites the limitation “the SAX process” in line 2 of both claims 2 and 12. This limitation is indefinite and/or unclear to readers. Therefore, “the SAX process” must be defined and spelled out in the claims. Claims 3 and 13 recites the limitation “the S-RLTC algorithm” in line 2 of both claims 3 and 13. This limitation is indefinite and/or unclear to readers. Therefore, “the S-RLTC algorithm” must be defined and spelled out in the claims. Allowable Subject Matter Claims 1, 4-11, and 14-20 are allowed. The following is a statement of reasons for the indication of allowable subject matter: Regarding claims 1 and 4-10, the prior art of record, when taken alone or in combination, cannot be construed as reasonably teaching or suggesting all of the elements of the claimed invention as arranged or provided in the manner as claimed by the applicant. Added for emphasis, the claim recitation “running, at the source, the lossy compression algorithm to obtain a series of raw values, and a sparse series of raw values; and transmitting, by the source to a target, the series of raw values, and the sparse series of raw values” is not found in the prior art of record. Therefore, the claims are allowed. Regarding claims 11 and 14-20, the prior art of record, when taken alone or in combination, cannot be construed as reasonably teaching or suggesting all of the elements of the claimed invention as arranged or provided in the manner as claimed by the applicant. Added for emphasis, the claim recitation “running, at the source, the lossy compression algorithm to obtain a series of raw values, and a sparse series of raw values; and transmitting, by the source to a target, the series of raw values, and the sparse series of raw values” is not found in the prior art of record. Therefore, the claims are allowed. Fauber (US 11,924,069) and Kornmeier et al. (US 11,403,310) are considered as closest relevant art to the claimed invention. Fauber (Fig. 1) discloses “a system architecture 100 comprises: a plurality of computers 102A, 102B, and 102C; communications network 104; and server 106. In turn, the computer 102A comprises time-series telemetry data compression component 108A; the computer 102B comprises time-series telemetry data compression component 108B; the computer 102C comprises time-series telemetry data compression component 108C; and the server 106 comprises time-series telemetry data compression component 108D. The computer 102A, computer 102B, and computer 102C can generate time-series telemetry data about their operation (e.g., processor utilization or memory utilization). This time-series telemetry data can be compressed by time-series telemetry data compression component 108A, time-series telemetry data compression component 108B, and time-series telemetry data compression component 108C, respectively, and transmitted to server 106 via communications network 104. The server 106 can receive this compressed time-series telemetry data, and use time-series telemetry data compression component 108D to process this data, such as by using it to determine whether each of computer 102A, computer 102B, and computer 102C are operating correctly” (line 5 of col. 5 to line 5 of col. 6). Kornmeier et al. (Fig. 4) discloses “a process 400 for enhancing time series data compression for improved data storage and retrieval. The process 400 includes: receiving, from a source device, original time series data to be stored in a data structure (block 410); sorting the original time series data to generate sorted time series data (block 420); identifying an index for the original time series data based on the sorted time series data (block 430); processing the sorted time series data, with a regression model, to generate compressed time series data and parameters associated with the compressed time series data (block 440); encoding the index to generate an encoded index (block 450); and storing the encoded index, the compressed time series data, and the parameters in the data structure (block 460)…” (line 23 of col. 11 to line 25 of col. 12). Contact Information Any inquiry concerning this communication or earlier communications from the examiner should be directed to KHAI M NGUYEN whose telephone number is (571)272-1809. The examiner can normally be reached Mon-Fri: 8:00 am - 4:30pm. Examiner interviews are available via telephone, in-person, and video conferencing using a USPTO supplied web-based collaboration tool. To schedule an interview, applicant is encouraged to use the USPTO Automated Interview Request (AIR) at http://www.uspto.gov/interviewpractice. If attempts to reach the examiner by telephone are unsuccessful, the examiner’s supervisor, Dameon E. Levi can be reached at 571-272-2105. The fax phone number for the organization where this application or proceeding is assigned is 571-273-8300.
