Prior art

US Patent 8457145, titled "Method and apparatus for bandwidth request/grant protocols in a wireless communication system," was granted on June 4, 2013, from an application filed on June 1, 2012, and claims priority from May 21, 1999.

Based on the provided patent text for US8457145, the following are the cited references and their potential relevance as prior art under 35 U.S.C. § 102. The earliest priority date for US8457145 is May 21, 1999, derived from U.S. patent application Ser. No. 09/316,518.

Identified Patent Citations for US8457145:

1. U.S. Pat. No. 5,675,573 (Karol et al.)

• Full Citation: U.S. Pat. No. 5,675,573 to Karol et al., issued October 7, 1997.
• Publication/Filing Date: Issued: October 7, 1997. The filing date would necessarily be prior to this issue date. This date precedes the priority date of US8457145.
• Brief Description: Karol et al. describe a bandwidth allocation system where packets or cells from different traffic flows contend for access to a shared processing fabric. Access is determined primarily by individual guaranteed bandwidth requirements associated with each traffic flow, and data packets are queued in separate logical buffers.
• Potential Anticipation under 35 U.S.C. § 102: This patent is discussed in the "BACKGROUND OF THE INVENTION" section of US8457145 as existing prior art. While it pertains to bandwidth allocation and queuing, it does not appear to disclose the specific combination of incremental and aggregate bandwidth requests, the detection of lost incremental requests, or the resetting of base station records based on aggregate requests, which are key features of independent claims 1 and 11 of US8457145. Therefore, it would likely not directly anticipate claims 1 or 11 under 35 U.S.C. § 102, but rather provides context for general bandwidth allocation challenges.

2. U.S. Pat. No. 6,016,311

• Full Citation: U.S. Pat. No. 6,016,311, issued January 18, 2000.
• Publication/Filing Date: Issued: January 18, 2000. This issue date is after the priority date of US8457145 (May 21, 1999). However, US8457145 states that US6016311 describes "one exemplary broadband wireless communication system" and is "commonly assigned", suggesting its effective filing date (which would determine its prior art status under § 102(e)) likely precedes May 21, 1999, making it a foundational reference.
• Brief Description: This patent describes a broadband wireless communication system (exemplified by system 100 in FIG. 1) that facilitates two-way communication between base stations and Customer Premises Equipment (CPEs). This system provides "bandwidth-on-demand" where CPEs request bandwidth based on service type and quality. It lays out the general architecture and the concept of bandwidth request/grant protocols in such a system.
• Potential Anticipation under 35 U.S.C. § 102: U.S. Pat. No. 6,016,311 describes the general wireless communication system and the basic idea of bandwidth request/grant protocols in a demand-driven environment. However, the descriptions within US8457145 regarding US6016311 do not indicate that it discloses the novel "self-correcting" aspects of US8457145, such as the combined use of incremental and aggregate bandwidth requests, the detection of lost requests, or the resetting of base station records. Therefore, it would likely not directly anticipate claims 1 or 11 of US8457145 under 35 U.S.C. § 102, as it does not appear to disclose all elements of these claims related to the specific self-correcting protocol.

Related Applications (Generally Not Anticipatory Prior Art under § 102 for Shared Priority)

The following patents are cited in the "RELATED APPLICATIONS" section of US8457145 and are continuations or continuation-in-parts (CIPs) that claim priority back to the same U.S. patent application Ser. No. 09/316,518, filed May 21, 1999. Since they share the same earliest effective filing date as US8457145 (for claims supported by that original application), they are generally not considered anticipatory prior art under 35 U.S.C. § 102 against claims in US8457145 that are fully supported by that common priority application. They represent different patent grants stemming from the same inventive lineage.
