Prior art

The USPTO provides a Patent Public Search tool that allows searching its database of patents and patent application publications. Using this tool, I will identify the most relevant prior art for US patent 8515765. Prior art generally refers to publicly available information about inventions that existed before the effective filing date of the claimed invention, which can include previously patented inventions, descriptions in printed publications, or inventions already in public use or on sale.

The provided patent text for US8515765 explicitly mentions three U.S. patent applications as prior art within its detailed description. Since the full "Claims" section was not provided, and web searches for "US8515765 claims" did not yield results that include the specific wording of the claims, I cannot definitively state which claims are potentially anticipated. However, based on the descriptions provided in US8515765 for these prior art references, I can infer general areas of overlap.

Here are the prior art references explicitly cited within US8515765:

1. U.S. Patent No. 7,634,409

   • Full Citation: U.S. patent application Ser. No. 11/513,269, entitled “Dynamic Speech Sharpening,” filed Aug. 31, 2006, which issued as U.S. Pat. No. 7,634,409 on Dec. 15, 2009.
   • Publication/Filing Date: August 31, 2006 (Filing Date).
   • Brief Description: This patent describes techniques of phonetic dictation to recognize a phoneme stream, used by the speech recognition engine in US8515765.
   • Potentially Anticipated Claims (Inferred): Claims related to the initial processing of an utterance by a speech recognition engine to generate preliminary interpretations, particularly those focusing on phonetic dictation and phoneme stream recognition.

2. U.S. Patent No. 7,640,160

   • Full Citation: U.S. patent application Ser. No. 11/197,504, entitled “Systems and Methods for Responding to Natural Language Speech Utterance,” filed Aug. 5, 2005, which issued as U.S. Pat. No. 7,640,160 on Dec. 29, 2009.
   • Publication/Filing Date: August 5, 2005 (Filing Date).
   • Brief Description: This patent describes how one or more context domain agents compete to determine the most appropriate domain for a given utterance, a process used within the context determination process of US8515765.
   • Potentially Anticipated Claims (Inferred): Claims related to the determination of context for a request, specifically those involving competing context domain agents to identify the most appropriate domain for an utterance.

3. U.S. Patent No. 7,949,529

   • Full Citation: U.S. patent application Ser. No. 11/212,693, entitled “Mobile Systems and Methods of Supporting Natural Language Human-Machine Interactions,” filed Aug. 29, 2005, which issued as U.S. Pat. No. 7,949,529 on May 24, 2011.
   • Publication/Filing Date: August 29, 2005 (Filing Date).
   • Brief Description: Similar to U.S. Patent No. 7,640,160, this patent also describes methods for supporting natural language human-machine interactions, particularly in mobile systems, and likely covers aspects of how context domain agents function.
   • Potentially Anticipated Claims (Inferred): Claims related to supporting natural language human-machine interactions, especially within mobile systems, and the use of context domain agents to interpret utterances and manage conversational flow.
