US 8270343

Here's a concise summary of US Patent 8270343:

• Title: Broadcasting of textual and multimedia information
• Assignee: Velocity Communication Technologies LLC (Current Assignee as of 2025-02-10). The original assignee was Freescale Semiconductor Inc.
• Inventors: Pierre Tardy and Laurence Poirier-Clarac
• Filing Date: 2004-12-20
• Issue Date: 2012-09-18
• Abstract: The patent describes a wireless communication system that broadcasts textual and multimedia information to a remote receiver. A signal manipulation function separates the content into multiple bursts of data sub-blocks. Each sub-block contains the textual data and a portion of the multimedia information. This approach aims to provide faster access to the "semantic" (most important) part of the transmitted information.

Plain-Language Overview of Independent Claims:

• Claim 1 (Wireless Communication System): This claim describes a system for broadcasting. It includes a broadcast transmitter and a server. The server receives a complete text file and associated multimedia information. It processes the text file into a single textual data block and divides the multimedia information into multiple smaller multimedia data sub-blocks. The server then sends these to the transmitter as multiple time-sliced packets. A key aspect is that each of these time-sliced packets contains the entire single textual data block along with one or more of the multimedia data sub-blocks. This ensures the textual information is repeatedly available with each packet.

• Claim 8 (Wireless Communication Unit): This claim describes the receiving device. It features a receiver and a signal manipulation circuit. The receiver is configured to receive multiple "time-sliced bursts" of data. The signal manipulation circuit processes these bursts such that from each burst, it can extract a single textual data block (which represents all the textual information from the original file) and one or more multimedia sub-blocks (which are portions of the original multimedia information). This claim describes the receiver-side logic complementing the broadcasting system.

• Claim 10 (Method of Broadcasting): This claim outlines the steps for broadcasting. It involves receiving a text file and multimedia content, then storing the complete text file as a single textual data block. Next, the multimedia information is divided into multiple multimedia data sub-blocks. Finally, the method includes providing these data components—the single textual data block and the multiple multimedia data sub-blocks—to a broadcast transmitter in the form of multiple time-sliced packets for transmission to a receiver.

Uncertainty Note:
The provided patent text includes extensive legal event history and lists several district court litigation cases filed in 2025 related to this patent. However, a search for "CAFC 2026 dockets 8270343" did not return any specific docket entries for patent 8270343 at the U.S. Court of Appeals for the Federal Circuit (CAFC) for the year 2026. This means there is no readily available information indicating active appellate litigation for this specific patent in the CAFC dockets as of April 26, 2026.

As of April 26, 2026, several litigation cases involving US Patent 8270343 have been identified. All listed cases were filed in 2025 by Velocity Communication Technologies LLC. The current status for all cases is "litigation," with no outcome yet specified:

The patent information also indicates "First worldwide family litigation filed," referring to a Darts-ip entry for family 34959917, which includes US8270343B2. However, specific plaintiff, defendant, jurisdiction, case number, filing date, and outcome for this "first worldwide family litigation" are not detailed beyond the fact that it exists and is listed as "litigation".

A search for CAFC dockets for 2026 related to US Patent 8270343 did not yield specific results indicating active appellate litigation for this patent in the CAFC as of April 26, 2026. General information on CAFC cases regarding indefiniteness rulings, inventorship, and infringement verdicts from prior years was found, but none directly related to 8270343. Additionally, information on PACER indicates it provides access to federal court records but does not directly list cases for US8270343 without specific search parameters. Unified Patents provides a portal to search litigation cases, and its records confirm the cases listed above for 8270343.

Proceedings overview

There are no AIA trial proceedings (Inter Partes Review, Post-Grant Review, or Covered Business Method) on file for US Patent 8270343 as of the most recent ingest from the USPTO Open Data Portal API. Web searches for PTAB proceedings related to US8270343 also did not reveal any active or concluded cases. This indicates that the patent's claims have not been challenged in AIA trials before the PTAB.

Strategic summary

As there are no PTAB proceedings on file for US8270343, all claims (1-16) of the patent remain untested by these specific AIA trial mechanisms. This means no claims have been canceled or sustained through IPR, PGR, or CBM trials. Consequently, there is no estoppel landscape established under 35 U.S.C. § 315(e)(2) for any petitioner or their privies regarding prior-art grounds that could have been raised in such proceedings. The patent owner has not been required to defend the patentability of its claims before the PTAB.

Recommended next steps

Since no PTAB activity exists for US8270343, a potential defendant currently facing assertion of this patent has a full range of prior-art grounds available if they consider filing an AIA trial petition (e.g., IPR or PGR, depending on eligibility). The absence of PTAB activity suggests that the patent has not yet undergone the scrutiny of these post-grant review processes.

NPE / troll-pattern signals

1. Shell-entity transfer — Present. The transfer on 2025-02-10 (recorded 2025-02-10) to Velocity Communication Technologies, LLC (Reel 063683/0273, inferred) is a transfer from an operating company (NXP) to an entity identified in search results as a "patent assertion entity" and "non-practicing entity (NPE) or patent troll". This entity is described as owning a large patent portfolio from other companies and immediately engaging in litigation.

2. Known asserter in the chain — Present. Velocity Communication Technologies, LLC (assignee on 2025-02-10, Reel 063683/0273, inferred) is widely identified as an NPE. RPX, a defensive aggregator, tracked Velocity's collection of patents from NXP and its subsequent litigation launch. Multiple sources confirm its status and extensive litigation activity since 2025.

3. Repeat correspondent across the chain — Unclear. The provided Google Patents legal events do not include correspondent information (attorney name, firm, address) for any of the assignments. Therefore, it is impossible to determine if a single correspondent appears multiple times across the chain.

4. Cascading transfers — Not present for ownership. While there are many security interest transfers and releases, the actual ownership transfer from NXP to Velocity Communication Technologies, LLC is a single, direct event on 2025-02-10. The preceding events are primarily security agreements and their releases, not consecutive ownership changes.

5. Pre-litigation transfer — Present. The patent was assigned to Velocity Communication Technologies, LLC on 2025-02-10. Litigation against various companies (e.g., OnePlus, TP-Link, Dell, Netgear, HP, D-Link, Cisco, Acer, ASUSTek, Juniper Networks, Lenovo, LG Electronics) commenced in July 2025. This means the first infringement suits began approximately five months after the patent was transferred to Velocity, falling within the 6-month window for a "pre-litigation transfer."

6. Bankruptcy fire-sale — Not present. The original assignee, Freescale Semiconductor Inc., was acquired by NXP, not dissolved or in bankruptcy. The transfer to Velocity was from NXP, not a bankruptcy trustee.

7. Privateering — Unclear. While NXP sold patents to Velocity, there's no explicit information in the provided text or search results detailing a specific agreement where NXP benefits from Velocity's assertions against NXP's competitors. The search results simply indicate Velocity acquired patents from companies like NXP.

8. Defensive aggregator (anti-NPE) — Not present. The chain ends with Velocity Communication Technologies, LLC, which is an NPE, not a defensive aggregator.

Verdict

NPE — high confidence

This verdict is strongly supported by two key signals: the transfer of the patent to Velocity Communication Technologies, LLC on 2025-02-10 (Reel 063683/0273, inferred), which is a known patent assertion entity, and the subsequent filing of multiple patent infringement lawsuits approximately five months later in July 2025, indicating a clear pre-litigation transfer. This pattern is characteristic of a patent being acquired for assertion purposes.

USPTO Assignment Center search for US8270343: https://assignmentcenter.uspto.gov/

Here's an analysis of the most relevant prior art for US Patent 8270343, based on its patent citations. The analysis will focus on whether each cited patent potentially anticipates claims 1, 8, or 10 of US8270343 under 35 U.S.C. § 102, noting the core inventive concept of US8270343: the separation of textual and multimedia information, and the repeated inclusion of the entire textual data block in each time-sliced packet/burst, alongside multimedia sub-blocks, for faster access to semantic data.

It is important to note that without direct access to the full text and claims of each cited prior art patent, the assessment of "potential anticipation" is based primarily on the title and the general understanding of the technology area, compared against the specific claims of US8270343 as provided in the patent summary.

US Patent 8270343 Key Independent Claim Elements to Assess for Anticipation:

• A system/method/unit that:
  • Separates a text file (textual information) from multimedia information.
  • Treats the entire text file as a single textual data block.
  • Divides the multimedia information into multiple multimedia data sub-blocks.
  • Broadcasts/receives these in multiple time-sliced packets/bursts.
  • Crucially, each time-sliced packet/burst comprises the single textual data block and one or more multimedia data sub-blocks.

Prior Art Reference: US20020078451A1

• Full Citation: US20020078451A1, Sony Corporation, "Transmitter system and transmitting method, receiver system and receiving method and transmission media"
• Publication/Filing Date: Publication Date: 2002-06-20. Filing Date: 1997-07-18.
• Brief Description: This patent broadly describes systems and methods for transmitting and receiving data, as well as the transmission media used.
• Potential Anticipation Analysis (35 U.S.C. § 102): While this patent is prior art due to its earlier filing date, its title is very general. It is unlikely to specifically disclose the unique data structuring of US8270343, which involves separating a complete textual data block from multimedia data sub-blocks and repeatedly including the entire textual data block in each time-sliced transmission packet. Therefore, it is unlikely to anticipate independent claims 1, 8, or 10 of US8270343 directly based on the information available.

Prior Art Reference: US20010000194A1

• Full Citation: US20010000194A1, Sequeira William J., "System and method for a master scheduler"
• Publication/Filing Date: Publication Date: 2001-04-05. Filing Date: 1998-08-21.
• Brief Description: This patent appears to describe a system and method for a master scheduler, which would typically manage tasks or resource allocation.
• Potential Anticipation Analysis (35 U.S.C. § 102): This patent is prior art. While a master scheduler could potentially influence data transmission timing, its title does not suggest the specific inventive concept of separating textual and multimedia content and repeatedly embedding the entire textual block in each time-sliced packet. Thus, it is unlikely to anticipate independent claims 1, 8, or 10 of US8270343.

Prior Art Reference: US6987980B1

• Full Citation: US6987980B1, Robert Bosch Gmbh, "Transmission frame and radio unit for transmitting short messages with different data format"
• Publication/Filing Date: Publication Date: 2006-01-17. Filing Date: 1998-12-08.
• Brief Description: This patent describes a transmission frame and radio unit designed for transmitting short messages that may have different data formats.
• Potential Anticipation Analysis (35 U.S.C. § 102): This patent is prior art. While it deals with transmitting data of different formats, the focus on "short messages" and the absence of any explicit mention of separating an entire textual data block for repetitive inclusion with multimedia sub-blocks in time-sliced bursts make direct anticipation of US8270343's independent claims 1, 8, or 10 unlikely.

Prior Art Reference: US6961346B1

• Full Citation: US6961346B1, Cisco Technology, Inc., "System and method for converting packet payload size"
• Publication/Filing Date: Publication Date: 2005-11-01. Filing Date: 1999-11-24.
• Brief Description: This patent covers systems and methods for adjusting or converting the size of packet payloads.
• Potential Anticipation Analysis (35 U.S.C. § 102): This patent is prior art. While US8270343 involves handling data within packets, the inventive step of US8270343 lies in the content organization within those packets (i.e., the repeated entire textual data block and split multimedia), not primarily in the conversion of payload size. Therefore, it is unlikely to anticipate independent claims 1, 8, or 10 of US8270343.

Prior Art Reference: US20020156804A1

• Full Citation: US20020156804A1, International Business Machines Corporation, "Displaying text of video in browsers on a frame by frame basis"
• Publication/Filing Date: Publication Date: 2002-10-24. Filing Date: 2001-04-19.
• Brief Description: This patent focuses on displaying text synchronized with video within web browsers, possibly on a frame-by-frame basis.
• Potential Anticipation Analysis (35 U.S.C. § 102): This patent is prior art. While it deals with the combination of text and video, its emphasis appears to be on the display aspect in a browser, rather than the specific broadcasting methodology of US8270343. The inventive step of US8270343 is the efficient transmission technique (time-slicing with repetitive entire textual data blocks) in a digital broadcast system. Without explicit disclosure of this specific transmission and packet structure, it is unlikely to anticipate independent claims 1, 8, or 10 of US8270343.

Prior Art Reference: US20020199148A1

• Full Citation: US20020199148A1, Koninklijke Philips Electronics N.V., "Cross media error protection method and system"
• Publication/Filing Date: Publication Date: 2002-12-26. Filing Date: 2001-06-20.
• Brief Description: This patent describes a method and system for error protection that can be applied across different media types.
• Potential Anticipation Analysis (35 U.S.C. § 102): This patent is prior art. While error correction is a component of robust digital broadcasting (as acknowledged by MPE-FEC in US8270343), the core inventive concept of US8270343 is not error protection itself, but the specific structuring and repetitive transmission of content for faster semantic updates. Therefore, it is unlikely to anticipate independent claims 1, 8, or 10 of US8270343.

• Brief Description: This patent describes a device and method for downloading web pages using distributed data flows.
• Potential Anticipation Analysis (35 U.S.C. § 102): This patent is prior art, as its filing date (2004-10-14) predates the priority date of US8270343 (2004-12-20). The concept of a "web page downloading device with distributed data flows" is potentially relevant, as web pages typically comprise textual and multimedia elements, and US8270343 mentions its applicability to "web-site broadcasting." If this patent teaches the separation of a web page's textual and multimedia components, and the repetitive transmission of the entire textual component within each portion of the distributed data flows alongside multimedia sub-blocks for faster access, it could potentially anticipate claims 1, 8, or 10. Without examining its detailed claims, it is not possible to state with high confidence, but it stands as one of the more conceptually aligned citations due to the nature of web content and distributed delivery.

The obviousness of US patent 8270343 under 35 U.S.C. § 103 can be analyzed by combining elements from the prior art references cited within the patent itself. The core inventive concept of US8270343, as defined by its independent claims, involves a system, unit, and method for broadcasting textual and multimedia information where a complete textual data block is packaged into each time-sliced packet (or burst) along with portions of multimedia information, allowing for faster updates of critical textual content in DVB-H environments.

A Person Having Ordinary Skill in the Art (PHOSITA) in DVB-H content delivery, at the time of the invention (priority date 2004-12-20), would have been motivated to efficiently deliver electronic service guides (ESGs) and similar rich content over wireless broadcast networks, particularly for mobile devices where bandwidth is limited and user experience demands quick access to essential information.

Problem Recognized in the Art

The patent's background explicitly highlights the problem: "as the data content becomes richer, the size of files on the data carousel increases to such an extent that transmission time becomes excessive." [cite: "However, as the data content becomes richer, the size of files on the data carousel increases to such an extent that transmission time becomes excessive."] It notes that "multimedia content significantly increases the size of the complete document," leading to "a need to deliver large amounts of data content in an efficient manner." [cite: "The addition of such multimedia content significantly increases the size of the complete document, which can typically require up to several MBytes in current data systems. Therefore, there is a need to deliver large amounts of data content in an efficient manner."] Furthermore, it states that "bandwidth is expensive," and content providers "do not want to allocate large amounts of bandwidth to the broadcasting of such documents" like ESGs. [cite: "In addition, in a wireless environment, bandwidth is expensive. Content Providers who provide electronic service guides (ESGs), such as television guides, do not want to allocate large amounts of bandwidth to the broadcasting of such documents."] Crucially, the patent identifies that "semantic data is more critical for the user than presentation data, as semantic (TV-related) data is essential and sufficient to begin watching TV whereas presentation data is provided to make the DVB-H guide more attractive." [cite: "Furthermore, semantic data is more critical for the user than presentation data, as semantic (TV-related) data is essential and sufficient to begin watching TV whereas presentation data is provided to make the DVB-H guide more attractive."] This clearly establishes a motivation for prioritizing the delivery of semantic (textual) data.

It discloses an "optimized carousel configuration technique" that utilizes "hierarchical data separation, with custom transport parameters, a custom repetition rate for the starting phase and caching of HTML EPG files for faster display." [cite: "In the art of data carousel networks, a paper by OtaDigi Herrero, C. Cesar, P. and Vuorimaa, P., published in the 6th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service, volume: 1, 1-3 Oct. 2003, discloses on pages: 231-234 an optimized carousel configuration technique. The proposed technique discloses a method whereby files required at a starting phase of a carousel operation are sent into the object carousel five times more often than a typical carousel operation. In particular, the paper discloses a mechanism of hierarchical data separation, with custom transport parameters, a custom repetition rate for the starting phase and caching of HTML EPG files for faster display."] This reference teaches the concept of prioritizing and frequently repeating essential data (like EPG information) in a data carousel for faster display.

They teach key features such as time-slicing (regrouping data into bursts to save power, where a receiver is only activated when a burst is sent) and Multi-Protocol Encapsulation-Forward Error Correction (MPE-FEC) for robust data transmission in mobile environments. The patent explicitly states that DVB-H utilizes time-slicing and MPE-FEC, and that "bursts and MPE-FEC frames correspond." [cite: "The preferred embodiment also utilises multiple-protocol encapsulation (MPE) and forward error correction (FEC), to efficiently transfer data files over a wireless interface. Generally, bursts and MPE-FEC frames correspond. This means there are typically an integer number of complete MPE-FEC frame per burst."]

Obviousness Analysis

Motivation to Combine:
A PHOSITA, aware of the bandwidth constraints and the need for rapid updates of essential ESG information in DVB-H systems (as highlighted by US8270343's background), would be motivated to combine Herrero's optimized data carousel techniques with the DVB-H broadcast standard. The motivation would be to apply the principle of prioritizing and frequently repeating critical data (as taught by Herrero for EPGs) to the specific time-sliced, burst-based transmission environment of DVB-H. The IBM patent would further reinforce the known advantage of separating and rapidly displaying textual information.

Combination and Obviousness:

• Separating Textual (Semantic) and Multimedia (Presentation) Information: Herrero teaches "hierarchical data separation" within an EPG context to prioritize certain files for "faster display." A PHOSITA would readily recognize that textual information (e.g., program titles, schedules) constitutes the "semantic" or critical "starting phase" data, while images or video are "presentation" data. The IBM patent further underscores the general concept of separating text from multimedia for display prioritization.

• Storing the Text File as a Single Textual Data Block: Once the textual information is identified as critical and deserving of priority (following Herrero), storing it as a coherent data block for efficient handling and repetition is a straightforward engineering implementation.

• Partitioning Multimedia Information into Multiple Sub-Blocks: Given the problem of large multimedia files causing excessive transmission times (as per US8270343's background), and the goal of optimizing carousel performance (Herrero), a PHOSITA would find it obvious to break down large multimedia content into smaller, manageable sub-blocks. This is especially true when integrating with DVB-H's burst-based transmission, where data is transmitted in discrete, limited-size bursts.

• Transmitting/Receiving in Multiple Time-Sliced Packets/Bursts: This element is directly taught by the DVB-H standards. The patent itself explicitly leverages DVB-H's time-slicing and MPE-FEC technologies.

• Each Time-Sliced Packet Comprising the Single Textual Data Block and One or More Multimedia Data Sub-Blocks: This is the most distinctive feature of the claims. Herrero teaches sending "files required at a starting phase... five times more often" for faster display of EPGs. If the "single textual data block" (the semantic ESG content) is identified as such a "starting phase" or critical file, then a PHOSITA, applying Herrero's principle to a DVB-H time-sliced environment, would find it obvious to include this complete textual data block in each time-sliced burst. This ensures that the essential textual information is delivered with maximum frequency and immediacy.

  Furthermore, DVB-H bursts (MPE-FEC frames) typically have a minimum size (e.g., at least 512 Kbits). If the complete semantic data block is relatively small (e.g., 50 Kbits, as mentioned in the patent), simply sending it alone in a 512 Kbit burst would be inefficient and waste valuable bandwidth. To address the problem of "expensive bandwidth" and the need to "deliver large amounts of data content in an efficient manner," a PHOSITA would be motivated to fill the remaining capacity of each time-sliced burst with portions of the less critical multimedia (presentation) data. This efficient use of bandwidth within predefined burst structures would be a routine design choice.

Conclusion:
The combination of Herrero et al. (teaching hierarchical data separation and frequent repetition of critical EPG files for faster display in data carousels) with the DVB-H standards (teaching time-slicing, bursts, and MPE-FEC in wireless broadcast) would render claims 1, 8, and 10 of US8270343 obvious to a PHOSITA. The motivation stems from the clear problem of efficient and rapid delivery of essential information in rich-content ESGs over bandwidth-constrained DVB-H networks, leading to the predictable design choice of embedding the frequently updated, critical textual data block in each burst, and then filling the remaining burst capacity with multimedia sub-blocks to maximize bandwidth utilization. The IBM patent provides additional general motivation for separating and prioritizing textual information in multimedia contexts.
