Prior art

US Patent 9667751, titled "Data feed acceleration," was granted on May 30, 2017, from an application filed on September 14, 2015. The patent generally describes systems and methods for accelerating data transmission, particularly for broadcast data like financial information and news feeds, by using real-time data compression and decompression to increase effective bandwidth and reduce latency.

The patent explicitly incorporates several other patents and patent applications by reference. These directly related documents are the most relevant prior art for US9667751.

Here's an analysis of the most relevant prior art cited within US9667751:

1. U.S. Pat. No. 6,195,024

• Full Citation: U.S. Pat. No. 6,195,024, issued on Feb. 27, 2001. [cite: The entire patent document, specifically the "CROSS REFERENCE TO RELATED APPLICATIONS" and "DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS" sections.]
• Publication/Filing Date: Issued Feb. 27, 2001. The filing date is Oct. 3, 2000, for U.S. Provisional Patent Application No. 60/237,571, which 6,195,024 claims benefit from.
• Brief Description: This patent is titled "Content Independent Data Compression Method and System." It describes a compression system that uses multiple different encoders to compress an input data stream, selecting the best compressed block based on compression ratios, regardless of the data content. [cite: The entire patent document, specifically the "DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS" section, under the sub-heading "a content-independent data compression system".]
• Potential Anticipation (35 U.S.C. § 102): This patent directly informs the "content-independent" compression aspects discussed in US9667751. Claims in US9667751 that relate to employing multiple encoders and selecting an optimal compressed block, or switching between compression schemes based on efficiency, could potentially be anticipated. Specifically, methods described in US9667751 that switch to a content-independent scheme when a content-dependent scheme's efficiency drops (as mentioned in the "DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS" section), or generally employing a plurality of different encoders for optimal compression (FIG. 5 and its description), would find this patent highly relevant.

2. U.S. Pat. No. 6,309,424

• Full Citation: U.S. Pat. No. 6,309,424, issued on Oct. 30, 2001. [cite: The entire patent document, specifically the "CROSS REFERENCE TO RELATED APPLICATIONS" and "DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS" sections.]
• Publication/Filing Date: Issued Oct. 30, 2001. The filing date is Oct. 3, 2001, for U.S. patent application Ser. No. 09/969,987 which 6,309,424 claims benefit from.
• Brief Description: US9667751 explicitly states that the concept of "acceleration" may be applied to the storage and retrieval of data to any memory or storage device using the compression methods disclosed in 6,309,424. [cite: The entire patent document, specifically the "DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS" section, under the sub-heading "a fundamental premise".] While the full text of 6,309,424 is not provided here, its description in US9667751 implies it covers data compression methods applicable to data storage and retrieval.
• Potential Anticipation (35 U.S.C. § 102): Claims in US9667751 that broadly cover data compression for accelerating data handling, especially those not strictly limited to network transmission but also encompassing storage and retrieval, could be anticipated by 6,309,424.

3. U.S. patent application Ser. No. 10/016,355

• Full Citation: U.S. patent application Ser. No. 10/016,355, filed on Oct. 29, 2001. [cite: The entire patent document, specifically the "CROSS REFERENCE TO RELATED APPLICATIONS" and "DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS" sections.]
• Publication/Filing Date: Filed Oct. 29, 2001.
• Brief Description: This application is referenced in US9667751 in relation to applying the concept of "acceleration" to data storage and retrieval, and also mentions a compression system employing both content-dependent and content-independent schemes. [cite: The entire patent document, specifically the "DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS" section, under the sub-heading "a fundamental premise" and "a compression system".]
• Potential Anticipation (35 U.S.C. § 102): Claims in US9667751 pertaining to the combination of content-dependent and content-independent compression schemes, or to the application of acceleration to data storage and retrieval, could be anticipated by this application.

4. U.S. patent application Ser. No. 09/481,243

• Full Citation: U.S. patent application Ser. No. 09/481,243, filed on Jan. 11, 2000. [cite: The entire patent document, specifically the "CROSS REFERENCE TO RELATED APPLICATIONS" and "DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS" sections.]
• Publication/Filing Date: Filed Jan. 11, 2000.
• Brief Description: This application is cited in US9667751 as disclosing "storage acceleration techniques." [cite: The entire patent document, specifically the "DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS" section, under the sub-heading "a fundamental premise".]
• Potential Anticipation (35 U.S.C. § 102): Any claims in US9667751 related to accelerating data storage or retrieval processes through compression or similar techniques would find this application relevant.

5. U.S. patent application Ser. No. 09/266,394

• Full Citation: U.S. patent application Ser. No. 09/266,394, filed on Mar. 11, 1999. [cite: The entire patent document, specifically the "CROSS REFERENCE TO RELATED APPLICATIONS" and "DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS" sections.]
• Publication/Filing Date: Filed Mar. 11, 1999.
• Brief Description: Similar to Ser. No. 09/481,243, this application also discloses "storage acceleration techniques." [cite: The entire patent document, specifically the "DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS" section, under the sub-heading "a fundamental premise".]
• Potential Anticipation (35 U.S.C. § 102): Claims in US9667751 that cover methods or systems for accelerating data storage and retrieval, particularly through compression, could be anticipated by this application.

It is important to note that the patent 9667751 itself provides the most explicit description of these prior art documents and their relevance, particularly within the "DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS" section, where it discusses the background and how its inventions build upon or incorporate aspects of these earlier filings.
