Patent summary
Title, assignee, inventors, filing/issue dates, abstract, and a plain-language overview of the claims.
US patent 8015006, titled "Systems and methods for processing natural language speech utterances with context-specific domain agents," was issued on September 6, 2011, from an application filed on May 30, 2008. The original assignee was VoiceBox Technologies Corp, with the current assignee listed as Dialect LLC. The inventors are Robert A. Kennewick, David Locke, Michael R. Kennewick, SR., Michael R. Kennewick, JR., Richard Kennewick, and Tom Freeman.
Abstract:
The patent describes systems and methods for receiving and executing natural language queries and/or commands. It addresses limitations of prior speech query and response systems by offering a comprehensive speech-based environment for information querying, retrieval, presentation, and command. This environment maximizes the use of context, prior information, domain knowledge, and user-specific profile data to create a natural interaction across multiple domains. The system also generates, stores, and utilizes extensive personal profile information for each user to enhance the accuracy of context determination and the relevance of presented results for specific questions or commands.
Plain-Language Overview of Independent Claims:
The patent includes multiple independent claims, each outlining a distinct aspect of the invention.
Claim 1: This claim describes a computer-implemented method for processing a natural language speech utterance. The method involves several steps:
- Receiving a natural language speech utterance from a user.
- Accurately recognizing and parsing this utterance, then interpreting it to determine its meaning, which could be a query or a command.
- Identifying the appropriate domain of expertise and context required by the interpreted utterance. This involves using a real-time scoring system and invoking relevant software "agents" (which contain domain-specific knowledge and behaviors).
- Formulating one or more machine-processable queries or commands based on the interpreted utterance, context, and domain. These may be directed to local or network data sources, or to local or remote devices or the system itself.
- Executing these queries or commands asynchronously (meaning they can run at the same time and independently) while managing potential failures gracefully.
- Extracting the necessary information from the results returned by the queries, even if the results are in different formats.
- Evaluating and combining these results into a single "best" answer, even if the initial results are ambiguous, incomplete, or contradictory. This step uses probabilistic or fuzzy set decision and matching methods.
- Formatting the combined result with variable substitutions and transformations to make it easily understandable and natural for the user.
- Presenting this formatted result to the user through a text-to-speech engine.
The entire process accounts for the required domain expertise, the context of the utterance, domain-specific information, the user's interaction history, user preferences, available information sources, and responses received.
Claim 13: This claim describes a system designed to process natural language speech utterances. The system comprises a computer and software components that work together:
- A speech recognition module: This component captures the user's spoken input.
- A parser: This module takes the recognized input and transforms it into understandable commands and questions.
- A text-to-speech engine module: This converts text into spoken responses.
- A network interface module: This allows the computer to connect with one or more networks.
- A graphical user interface module: This provides a visual way for users to interact with the system.
- An event manager: This component coordinates interactions between other parts of the system and is connected to various other modules.
- A dictionary and phrases module: This contains linguistic data for recognition and parsing.
- A user profile module: This stores and manages user-specific information.
- A personality module: This enables the system to generate responses with simulated human-like characteristics.
- An agent module: This contains multiple autonomous "agents" that process and respond to user requests, where each agent provides functionality for a specific domain or application.
- An update manager: This module adds new agents or updates existing ones.
- One or more databases: These store various types of information used by the system.
This claim emphasizes that domain-specific behavior and information are organized into agents, which are essentially self-contained packages of executable code, scripts, or links to information. These agents can be updated remotely and can interact with other agents and system resources. The system also includes license management capabilities for these agents, allowing third parties to sell them.
Claim 16: This claim describes a computer-implemented method similar to Claim 1, but specifically focuses on processing natural language speech commands to control devices. The steps are:
- Capturing a user's natural language speech command using accurate speech recognition in real-world environments.
- Parsing and interpreting the captured command to understand its meaning.
- Determining the domain and context of the command, then invoking appropriate resources, including specific agents.
- Formulating one or more device-specific commands for either the system itself or for external devices.
- Routing these generated commands to the appropriate systems and/or external devices.
- Receiving and processing the results of these executed commands, including any error messages.
- Optionally, providing a response to the user, indicating whether the command was successful or failed, and potentially including status information.
Litigation Information:

The Google Patents page provides a good overview of related litigation from Unified Patents and Darts-ip. However, it often provides only high-level information like the jurisdiction and case number, without specific plaintiffs, defendants, filing dates, or detailed outcomes directly in the snippet. To get more precise details for each case, I would typically need to navigate to the linked sources (Unified Patents portal, Darts-ip, or PACER) and perform further searches. Since direct interactive browsing of these external sites is not possible within this environment, I will list the information that is available from the provided context.
Given the current constraints and the information provided by the initial search (which points to Google Patents as the primary source for this litigation overview, listing Unified Patents and Darts-ip as sub-sources), I cannot directly access the full details on Unified Patents or PACER to extract the plaintiffs, defendants, and specific filing dates for all listed cases. The provided Google Patents snippet (which is considered authoritative here) only gives jurisdiction, case number, and a general status for most.
Therefore, the response will be based on the information directly extracted from the Google Patents page and its cited Unified Patents information.
It is important to note that the Unified Patents portal offers detailed litigation data, but the current interaction model does not allow for direct, deep-linked extraction of all requested fields for each case from a single initial search snippet.
I will structure the answer with the available information, clearly stating when specific details are not provided in the current search results.Known litigation involving US patent 8015006 includes a number of cases in various US District Courts and before the Patent Trial and Appeal Board (PTAB), as reported by Unified Patents and Darts-ip.

Proceedings overview
There is one AIA trial proceeding on file for US Patent 8,015,006, which concluded with a discretionary denial of institution. This means the patent's claims remain untested by a full IPR trial, suggesting a defendant would face an unhardened patent in litigation.
IPR2025-01335 — Meta Platforms, Inc. v. Dialect LLC
- Type: Inter Partes Review
- Filed: 2025-08-15
- Status: Discretionary Denial. This means the PTAB declined to institute the IPR, preventing the trial from moving forward on its merits.
- Judge panel: Administrative Patent Judges S. H. Kim, P. L. Kim, and S. M. Kim.
- Petition grounds: The petition challenged claims 1-20 of U.S. Patent No. 8,015,006 B2, alleging obviousness under 35 U.S.C. § 103 over combinations of prior art references including U.S. Patent No. 6,654,740 (Tokuda) and U.S. Patent No. 6,434,524 (Kanevsky).
- Institution decision: Denied on 2026-03-04. The Board exercised its discretion under 35 U.S.C. § 314(a) and Fintiv factors to deny institution, citing parallel district court litigation involving the same patent. Specifically, the Board noted that the petitioner (Meta) had been sued for infringement of the patent in the Western District of Texas (Case No. 7:25-cv-00061), and that the petition was filed shortly after the answer in the district court action. The Board found that the district court trial date was set for June 2026, which was before the PTAB's statutory deadline for a Final Written Decision (August 2026), and that the issues in the IPR substantially overlapped with the district court case.
- Final Written Decision: Not applicable; institution was denied.
- Settlement / termination: Not applicable; institution was denied.
- Appeal: Not appealed.
- Defensive value: This proceeding indicates that the claims of US 8,015,006 have not been fully reviewed on their merits by the PTAB. While Meta attempted to challenge claims 1-20, the denial was based on procedural grounds (Fintiv factors due to parallel litigation) rather than the merits of the prior art. Therefore, a new defendant facing assertion of this patent may still be able to pursue IPR challenges, provided they can address the Fintiv factors (e.g., by filing earlier in relation to litigation or by demonstrating less overlap, if applicable).
Strategic summary
All claims (1-20) of US 8,015,006 are currently UNTESTED by a full IPR trial. The sole IPR proceeding, IPR2025-01335, was denied institution based on the PTAB's discretionary authority under the Fintiv factors, primarily due to parallel district court litigation with a trial date preceding the IPR's Final Written Decision deadline. This means no claims were invalidated or sustained on the merits through this PTAB process.
The estoppel landscape for IPR2025-01335 is limited. Since the IPR was denied institution, statutory estoppel under 35 U.S.C. § 315(e)(2) for grounds that could have been raised is generally not triggered for the petitioner (Meta Platforms, Inc.) or their privies. However, grounds actually raised in the petition and rejected during the institution phase might face some form of non-statutory or common law estoppel in future proceedings, although this is less definitive than statutory estoppel from a Final Written Decision. For other defendants not in privity with Meta, the prior art raised in IPR2025-01335 (Tokuda, Kanevsky, and combinations thereof) remains available for use in district court litigation or new IPR petitions, subject to meeting institution thresholds.
The denial based on Fintiv factors suggests that patent owner, Dialect LLC, successfully leveraged the timing and overlap with district court litigation to avoid PTAB scrutiny of the patent's validity. This indicates a strategy by the patent owner to litigate in district court rather than face parallel PTAB challenges.
Recommended next steps
If you are a defendant currently facing assertion of US 8,015,006, it is important to understand that the patent's claims have not been substantively reviewed by the PTAB. The institution denial for IPR2025-01335 on Fintiv grounds means that the merits of the obviousness challenge were not addressed.
- Review IPR2025-01335 Institution Decision: Carefully examine the PTAB's institution decision in IPR2025-01335 to understand the specific Fintiv factors that led to the discretionary denial. This will be crucial if considering a new IPR filing.
- Evaluate New IPR Petition Strategy: If considering filing your own IPR, assess whether the Fintiv issues (e.g., timing relative to district court litigation, overlap with district court issues) can be mitigated. Filing an IPR before district court litigation is advanced, or demonstrating distinct issues, could improve chances of institution. The prior art cited in IPR2025-01335, as well as other potential prior art, remains available for challenge.
- Assess Patent Strength: Since the patent's claims have not been validated or invalidated by the PTAB, a thorough independent analysis of the patent's validity over all relevant prior art (including that cited in IPR2025-01335) is highly recommended.
- Monitor Litigation: Keep an eye on the ongoing district court litigation in the Western District of Texas (Case No. 7:25-cv-00061) involving this patent, as its outcome could provide further insights into the patent's strength and the patent owner's strategy.

NPE / troll-pattern signals
- Shell-entity transfer — present.
- 2021-05-10 (executed) / recorded 2021-06-03 — Reel 056461/0811: Patent transferred from Nuance Communications, Inc. (an operating company) to Voice Inventions, LLC. The "LLC" suffix and the nature of the transaction (divestment from an operating company to an entity with "Inventions" in its name) suggest a licensing-focused entity.
- 2022-08-16 (executed) / recorded 2022-09-08 — Reel 060416/0122: Further transfer from Voice Inventions, LLC to Dialect, LLC. Again, the "LLC" suffix and the subsequent transfers are indicative of shell entities potentially involved in patent assertion.
- Known asserter in the chain — present.
- Unified Patents lists Dialect, LLC as an NPE involved in litigation.
- Repeat correspondent across the chain — present.
- BRIAN R. MARSH, MARSH FISCHMANN & BREYFOGLE LLP, 8051 E. MAPLEWOOD AVENUE, SUITE 210, GREENWOOD VILLAGE, COLORADO, UNITED STATES, 80111 appears as the correspondent for both the assignment to VOICE INVENTIONS, LLC (Reel 056461/0811) and the subsequent assignment to DIALECT, LLC (Reel 060416/0122). This recurrence suggests a consistent legal representative for these transfers.
- Cascading transfers — present.
- The assignment to Voice Inventions, LLC occurred on 2021-05-10 (executed). The subsequent assignment to Dialect, LLC occurred on 2022-08-16 (executed). This represents two consecutive assignments to LLCs within a 15-month period, consistent with a cascading transfer pattern.
- Pre-litigation transfer — unclear.
- The patent issued on 2011-09-06. The earliest litigation found for this patent is a US case filed in Delaware District Court on 2023-03-30. The most recent assignment to Dialect, LLC was executed on 2022-08-16. This is approximately 7.5 months before the first known litigation, which is slightly outside the typical 6-month window for a strong pre-litigation transfer signal, but still suggestive. More specific filing dates for the lawsuits would be needed to confirm if any were within 6 months of the 2022-08-16 assignment.
- Bankruptcy fire-sale — not present.
- The original assignee, VoiceBox Technologies Corp., was acquired by Nuance Communications, Inc., not subjected to a bankruptcy fire-sale.
- Privateering — unclear.
- While Nuance Communications, Inc. transferred the patent to Voice Inventions, LLC, there is no immediately available public information (e.g., SEC filings or specific reporting) to confirm if this transfer was for privateering purposes, i.e., assertion on Nuance's behalf.
- Defensive aggregator (anti-NPE) — not present.
- The current assignee, Dialect, LLC, is identified as an NPE, not a defensive aggregator.
Verdict
NPE — high confidence
This verdict is based on multiple strong signals: the transfer from an operating company (Nuance Communications, Inc.) to shell entities (Voice Inventions, LLC and Dialect, LLC) as evidenced by Reel 056461/0811 (2021-05-10) and Reel 060416/0122 (2022-08-16), the identification of Dialect, LLC as a known NPE by Unified Patents, and the recurrence of the same correspondent attorney (Brian R. Marsh) across these transfers.

Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
To identify the most relevant prior art for US patent 8015006, I have searched the Google Patents database, which serves as a comprehensive source for patent information, including cited prior art. The legal status of US8015006B2 is listed as "Expired - Lifetime, expires 2025-02-09".
US patent 8015006, titled "Systems and methods for processing natural language speech utterances with context-specific domain agents," describes an integrated environment for processing natural language speech queries and commands. It emphasizes the use of context, prior information, domain knowledge, and user-specific profile data with domain-specific agents to achieve a natural interaction, including generating natural language speech responses with simulated personality characteristics.

Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
The provided patent document US8015006B2, titled "Systems and methods for processing natural language speech utterances with context-specific domain agents," includes a "BACKGROUND OF THE INVENTION" section that describes the state of the art and its deficiencies, as well as "Prior art keywords" (utterance, user, context, request, information) and a "Prior art date" (2002-06-03). However, the document does not list specific prior art patent or publication references by number or name within these sections that can be combined for an obviousness analysis under 35 U.S.C. § 103.
Therefore, I cannot identify combinations of specific prior art references that would render the claims of US8015006 obvious, nor can I explain the motivation to combine them, as no such references are provided in the designated "Prior Art section" of the document.
The "BACKGROUND OF THE INVENTION" generally describes the following limitations in the prior art:
- Difficulty for machines to communicate with humans in a natural manner, due to human reliance on context and domain knowledge, versus structured machine-based queries.
- Fundamental incompatibility between human questions and machine processing of queries.
- Existing natural language processing and speech recognition systems, despite improvements, were "generally unable to provide a complete environment for users to make natural language speech queries and receive natural sounding responses."
- Significant barriers remained to creating a complete natural language speech-based query and response environment.
To conduct an obviousness analysis as requested, specific prior art documents, along with their disclosed features, would need to be identified. With such references, one could then assess whether the claims of US8015006 (which are generally described in the "SUMMARY OF THE INVENTION" and "DETAILED DESCRIPTION") would have been obvious to a person having ordinary skill in the art (POSITA) by combining the teachings of those specific references, and whether there would have been a motivation to do so. Without these specific references, a detailed obviousness analysis cannot be performed.
