Title: Memory units with packet processor for decapsulating read write access from and encapsulating response to external devices via serial packet switched protocol interface

Assignee: Edgecomm LLC (Current Assignee as of 2025-10-10) (Original Assignee: Psimast Inc)

Inventor: Viswa Nath Sharma

Filing Date: 2010-10-25

Issue Date: 2012-07-31

Abstract: A computing and communication chip architecture is provided wherein the interfaces of processor access to the memory chips are implemented as a high-speed packet switched serial interface as part of each chip. In one embodiment, the interface is accomplished through a gigabit Ethernet interface provided by protocol processor integrated as part of the chip. The protocol processor encapsulates the memory address and control information like Read, Write, number of successive bytes etc, as an Ethernet packet for communication among the processor and memory chips that are located on the same motherboard, or even on different circuit cards. In one embodiment, the communication over head of the Ethernet protocol is further reduced by using an enhanced Ethernet protocol with shortened data frames within a constrained neighborhood, and/or by utilizing a bit stream switch where direct connection paths can be established between elements that comprise the computing or communication architecture.

Plain-Language Overview of Independent Claims:

• Claim 1 (Apparatus): This claim describes a chip architecture for integrated circuitry. It includes at least one memory device and a unique packet processor associated with each memory device, both co-located on a semiconductor die package. The packet processor provides read and write access to the memory device for an external device. It does this by taking incoming packets (from the external device) that conform to a serial protocol, decapsulating the address, data, and control information, and then encapsulating data (including the decapsulated address and control information) into a new packet conforming to the same serial protocol to send back to the external device in response. This communication occurs over at least one high-speed packet switched serial interface, which is accessible via an external port on the semiconductor die package.

• Claim 6 (Method): This claim outlines a method for implementing the chip architecture described in Claim 1. It involves providing a semiconductor die package with co-located memory devices and associated packet processors. The method includes the steps performed by the packet processor as described in Claim 1: decapsulating information from received serial packets for memory access and encapsulating response data into serial packets for transmission back to the external device, all via a high-speed packet switched serial interface.

• Claim 11 (Computer Readable Media): This claim covers computer-readable media containing instructions for implementing the chip architecture. These instructions define the co-located memory device(s) and associated packet processor(s) on a semiconductor die package, where the packet processor functions to decapsulate and encapsulate information for external device memory access via a high-speed packet switched serial interface, as detailed in Claim 1. The instructions also define at least one external port for accessing this interface.

CAFC 2026 Dockets:
As of April 26, 2026, a search of the CAFC 2026 dockets did not return any specific litigation mentioning US patent 8234483. The search results provided information on other patent cases (e.g., US Patent No. 8,458,689) and general CAFC activity, but not for 8234483.

Proceedings overview

A search of the USPTO's Open Data Portal (ODP) API for US Patent 8234483 indicates no AIA trial proceedings on file as of the most recent ingest. A supplementary web search for IPR, PGR, or CBM proceedings related to US8234483 also did not return any results. Therefore, there are no PTAB proceedings associated with this patent.

Strategic summary

As of 2026-05-26, all claims of US8234483 (Claims 1-16) remain UNTESTED in AIA trial proceedings. There have been no IPRs, PGRs, or CBMs filed against this patent.

Since no PTAB proceedings have been initiated, there is no estoppel landscape established under 35 U.S.C. § 315(e)(2). All prior-art grounds, whether previously raised or not, remain available for a potential petitioner to assert in a new AIA trial.

The absence of PTAB activity is a notable signal. Well-asserted patents often become targets for IPRs by accused infringers or defensive aggregators, especially given the ongoing litigation in district courts as noted in the "Litigation summary" section. The fact that the patent is currently being asserted in multiple lawsuits filed in 2025 without triggering any PTAB challenges to date could imply several things:

• The current defendants may be pursuing other litigation strategies.
• They may be in the early stages of preparing PTAB petitions.
• The claims of the patent, despite the ongoing litigation, might be perceived as robust against obviousness/anticipation challenges based on existing prior art, or the cost-benefit analysis of an IPR has not yet favored filing.

Recommended next steps

If you are a defendant facing assertion of US8234483:

• Absence of PTAB activity: Confirm this absence by performing a direct search on the USPTO PTAB E2E Public Search system using the patent number US8234483. This will provide the most up-to-date information.
• Evaluate IPR potential: Given the patent has not been challenged at the PTAB, thoroughly evaluate the potential for filing an IPR (or PGR, if applicable given the priority date and publication date of the original application 12/025,720, which has a publication date of 2008-08-07). The detailed prior art analysis provided in the "Prior art" and "Obviousness" sections of this report should be a starting point. This patent's priority date is 2007-02-02, so it is generally subject to AIA rules for IPR.
• Monitor for new filings: Continuously monitor the PTAB dockets for any newly filed petitions against US8234483, as this landscape can change rapidly, especially with active district court litigation.

NPE / troll-pattern signals

1. Shell-entity transfer — present.

   • 2020-05-26 Assignment to OPTICAL LICENSING LLC: The name "Optical Licensing LLC" strongly suggests a licensing-focused entity.
   • 2021-02-10 Assignment to KIRITIN, INC.: This name does not immediately suggest an operating company.
   • 2025-10-10 Assignment to EDGECOMM LLC: EdgeComm LLC is explicitly identified as having "advanced AI predictions and analytics on patent cases" and focuses on "law firms, opponents, and courts", indicating a business model centered around patent litigation and assertion, rather than product manufacturing.

2. Known asserter in the chain — present. EdgeComm LLC is the current assignee. RPX has identified EdgeComm LLC as a plaintiff in patent litigation, specifically noting complaints filed in the Western District of Texas against Marvell Semiconductor and NVIDIA in October 2025, and earlier complaints in the Eastern District of Texas in May 2025. Additionally, EdgeComm LLC has filed a case against Super Micro Computer, Inc. in May 2026. This confirms EdgeComm LLC as an active patent asserter.

3. Repeat correspondent across the chain — unclear. The provided snippets from Google Patents legal events do not include correspondent information (attorney name, firm, address) for the recorded assignments. Therefore, it is not possible to determine if there is a repeat correspondent.

4. Cascading transfers — present. The patent underwent three consecutive assignments in a relatively short period: from Psimast Inc. to Optical Licensing LLC in May 2020, then to KIRITIN, INC. in February 2021 (within 9 months), and finally to Edgecomm LLC in October 2025. This shows a pattern of transfers between entities, with at least one transfer occurring in under 24 months.

5. Pre-litigation transfer — present. The patent was assigned to Edgecomm LLC on 2025-10-10. EdgeComm LLC filed infringement suits in the Western District of Texas against Marvell Semiconductor and NVIDIA in October 2025, and previously in the Eastern District of Texas in May 2025. This indicates that the assignment to Edgecomm LLC occurred very close to or concurrently with the initiation of litigation, strongly suggesting the transfer was arranged to enable assertion.

6. Bankruptcy fire-sale — not present. There is no information to suggest any of the assignors or assignees have filed for bankruptcy.

7. Privateering — unclear. While the patent has been transferred to a known NPE, there is no explicit information in the provided snippets (such as SEC filings or specific news coverage) to indicate that an operating company transferred the patent to Edgecomm LLC to assert on its behalf against competitors.

8. Defensive aggregator (anti-NPE) — not present. The chain terminates with Edgecomm LLC, which is an active patent asserter, not a defensive aggregator.

Verdict

NPE — high confidence

This verdict is justified by the presence of several strong signals. Edgecomm LLC, the current assignee, is a known patent asserter, as evidenced by multiple infringement suits filed in 2025 and 2026 shortly after acquiring the patent. The assignment chain also exhibits cascading transfers between entities with names suggesting a licensing-only focus (Optical Licensing LLC, KIRITIN, INC.) before reaching Edgecomm LLC. The pre-litigation transfer to Edgecomm LLC in October 2025, closely preceding or coinciding with new infringement filings, further reinforces this conclusion.

Verification of assignment records can be performed at the USPTO Patent Assignment Search portal.

To identify the most relevant prior art for US patent 8234483, I will examine the patent's own cited references as listed on Google Patents, as these are the documents the examiner and inventor considered during prosecution. The information provided in the prompt's "Obviousness" section already lists these citations, which are key for identifying potentially anticipatory prior art under 35 U.S.C. § 102.

Here's an analysis of the patent citations and their potential relevance to anticipating the claims of US8234483:

Cited Prior Art and Potential Anticipation

The patent US8234483 itself lists several prior art references in its "Cited By (Examiner)" and "Patent Citations" sections. For clarity, I will focus on the most relevant references directly discussed in the "Obviousness" section of the provided context, which are explicitly presented as foundational for the invention's background.

1. US5613071A: Method and apparatus for providing remote memory access in a distributed memory multiprocessor system

• Full Citation: US5613071A
• Publication/Filing Date: Filed: 1995-07-14 / Granted: 1997-03-18
• Brief Description: This patent by Intel Corporation describes a method and apparatus for remote memory access in a distributed memory multiprocessor system. It focuses on providing efficient access to memory that is not locally attached to a processor.
• Potential Anticipated Claim(s) (under 35 U.S.C. § 102): This patent establishes the concept of remote memory access in a multiprocessor system, which is a foundational element. However, it does not explicitly detail the packet-switched serial interface as a co-located component with the memory and its specific encapsulation/decapsulation functions as defined in Claim 1 of US8234483. It might provide context for the general problem of memory access, but its detailed anticipation of the specific mechanism in US8234483 is less direct without further analysis of its communication protocols.

2. US20040019704A1: Multiple processor integrated circuit having configurable packet-based interfaces

• Full Citation: US20040019704A1
• Publication/Filing Date: Filed: 2002-05-15 / Published: 2004-01-29
• Brief Description: This patent application by Barton Sano describes a multiple processor integrated circuit with configurable packet-based interfaces. It addresses using packet-based communication within an integrated circuit environment.
• Potential Anticipated Claim(s) (under 35 U.S.C. § 102): This reference is highly relevant. It explicitly teaches an "integrated circuit having configurable packet-based interfaces" and "multiple processors." This directly bears on the "packet processor" and "high-speed packet switched serial interface" aspects of Claim 1 of US8234483, especially the use of packets for communication within a chip. If the interfaces described are serial and are used for memory access in a manner that includes decapsulation/encapsulation, it could potentially anticipate Claim 1 and its dependent method/computer-readable media claims (Claims 6 and 11). The degree of anticipation would depend on whether it teaches the specific co-location of the packet processor with the memory device on the same semiconductor die and the explicit function of decapsulating address, data and control information for memory access.

3. US6850998B2: Disk array system and a method for controlling the disk array system

• Full Citation: US6850998B2
• Publication/Filing Date: Filed: 2001-09-06 / Granted: 2005-02-01
• Brief Description: This patent by Hitachi, Ltd. concerns a disk array system and its control method. It deals with data management and access in storage systems.
• Potential Anticipated Claim(s) (under 35 U.S.C. § 102): While this patent deals with data access in storage systems, its primary focus on disk arrays makes it less directly relevant to the processor-memory interface with an integrated packet processor on a semiconductor die for main memory access as described in US8234483. It is unlikely to anticipate Claim 1 directly as it operates in a different functional domain (disk storage vs. processor-main memory).

4. US6928505B1: USB device controller

• Full Citation: US6928505B1
• Publication/Filing Date: Filed: 1998-11-12 / Granted: 2005-08-09
• Brief Description: This patent by Edwin E. Klingman describes a USB device controller.
• Potential Anticipated Claim(s) (under 35 U.S.C. § 102): A USB device controller manages serial communication, but it is typically for peripheral devices and does not address the core problem of high-speed processor-to-main memory access with co-located packet processors on a semiconductor die, as claimed in US8234483. It is unlikely to anticipate Claim 1.

5. US7352763B2: Device to receive, buffer, and transmit packets of data in a packet switching network

• Full Citation: US7352763B2
• Publication/Filing Date: Filed: 2000-06-26 / Granted: 2008-04-01
• Brief Description: This Intel Corporation patent describes a device for receiving, buffering, and transmitting data packets in a packet switching network.
• Potential Anticipated Claim(s) (under 35 U.S.C. § 102): This patent is very relevant as it deals with "packet switching networks" and "receiving, buffering, and transmitting packets." It could potentially anticipate elements of Claim 1, particularly the general concept of a packet processor handling packetized data. The key differentiating factor for US8234483 would be the explicit co-location with the memory device on a semiconductor die and the specific function of decapsulating memory address and control information for direct memory access, rather than just general network packet handling. Further analysis would be needed to see if it teaches all limitations of Claim 1.

6. US7848825B2: Master/slave mode for sensor processing devices

• Full Citation: US7848825B2
• Publication/Filing Date: Filed: 2007-01-03 / Granted: 2010-12-07
• Brief Description: This [Apple Inc.](/litigations/by-plaintiff/Apple%20Inc.) patent relates to master/slave mode operation for sensor processing devices.
• Potential Anticipated Claim(s) (under 35 U.S.C. § 102): This patent's focus on sensor processing devices and master/slave modes appears unrelated to the core aspects of packet-switched serial interfaces for processor-memory access as claimed in US8234483. It is unlikely to anticipate Claim 1.

Most Relevant Prior Art for Anticipation (under 35 U.S.C. § 102):

Based on the descriptions, US20040019704A1 (Multiple processor integrated circuit having configurable packet-based interfaces) and US7352763B2 (Device to receive, buffer, and transmit packets of data in a packet switching network) are the most likely candidates to potentially anticipate elements of Claim 1 of US8234483.

• US20040019704A1 is particularly strong because it describes packet-based interfaces within an integrated circuit for multiple processors, which directly relates to the context of US8234483. The extent of anticipation hinges on whether it explicitly teaches the co-location of a packet processor with memory on a semiconductor die for providing read/write access via decapsulation/encapsulation of memory access specific information.
• US7352763B2 covers the general operation of packet processing in a network. Its anticipatory strength would depend on whether this general packet handling device is also taught to be co-located with memory on a die and configured for memory access requests (address, data, control) via decapsulation and encapsulation.

Obviousness Analysis (35 U.S.C. § 103) for US8234483

This analysis identifies combinations of prior art references that would render the claims of US patent 8234483 obvious to a person having ordinary skill in the art (POSA) at the time of the invention (priority date 2007-02-02), and articulates the motivation for such combinations.

The independent claims of US8234483 (Claims 1, 6, and 11) focus on a chip architecture where a packet processor is co-located with a memory device on a semiconductor die. This packet processor decapsulates serial packetized memory access requests (address, data, control) from an external device and encapsulates responses back to the external device, all via a high-speed packet switched serial interface.

Claim 1: Apparatus Obviousness

Combination 1: US20040019704A1 (Sano) in view of general knowledge of packet processing and serial interfaces.

• US20040019704A1 (Sano): This reference discloses a "multiple processor integrated circuit having configurable packet-based interfaces". Sano teaches using packet-based communication within an integrated circuit environment for communication between processors. This reference provides the core concept of packet-based interfaces on a chip.

  • Sano explicitly teaches an "integrated circuit having configurable packet-based interfaces" and "multiple processors". This covers the "semiconductor die package" and "packet processor" aspects of Claim 1 in a broad sense, and packet-based communication within the chip.
  • It also teaches "configurable" interfaces, implying the ability to define packet protocols.

• Motivation to Combine/Modifications: A POSA, seeking to improve processor-memory communication efficiency and overcome the "memory wall" or "memory gap" problem (as described in the background of US8234483), would have been motivated to apply Sano's packet-based on-chip communication to memory access. The background of US8234483 itself notes that the "memory gap problem is further compounded by the need to address a large memory capacity" and that "One solution employed in the prior art to overcome the memory wall/memory gap problem is to eliminate the parallel bus interface between the processor and memory and use a serial backplane interface instead of a parallel bus". This highlights a recognized problem and a known general solution (serial interfaces).

  • Co-location of packet processor with memory: Given that Sano teaches packet-based interfaces on an integrated circuit with multiple processors, a POSA would readily extend this to include memory devices (which are fundamental components in any processor system) co-located on the same die or package. This is a logical design choice to minimize latency and improve performance by bringing the interface logic closer to the resource it serves, consistent with the objective of addressing the memory wall problem.
  • High-speed packet switched serial interface: The background of US8234483 also highlights the trend of migrating to serial interfaces for I/O and backplanes due to the limitations of parallel buses at high speeds. The combination of packet-based communication (Sano) with high-speed serial interconnects was a known trend in computing architectures (e.g., PCI-Express, Infiniband, Gigabit Ethernet, all mentioned in the background of US8234483 as "industry standard I/O protocols" or "hierarchical packet-based interconnection fabric"). A POSA would have known to implement the packet-based interfaces taught by Sano using a high-speed serial connection to achieve the performance benefits desired for memory access.
  • Decapsulating/Encapsulating memory access information: The functions of decapsulating address, data, and control information from a packet and encapsulating response data into another packet are standard operations for any packet-based communication system interfacing with a resource. When adapting a packet-based interface for memory access, it would be obvious to a POSA to define a packet format that includes memory address, data, and control commands (like Read/Write) and to implement logic to extract (decapsulate) and insert (encapsulate) this information. This is a routine engineering design choice for communicating with memory over a packet-switched medium.

Conclusion for Claim 1: US20040019704A1, combined with the general knowledge in the art regarding the advantages of high-speed serial communication, the need to address the memory wall problem, and standard packet processing techniques for resource access, would render Claim 1 obvious.

Claim 6: Method Obviousness

Combination 1: The method inherent in the apparatus of Claim 1, as rendered obvious by US20040019704A1 and general knowledge.

• Claim 6 describes a method comprising steps that directly correspond to the functions of the apparatus in Claim 1: "providing a semiconductor die package having co-located thereon at least one memory device with at least one packet processor...adapted to provide an external device read and write access...by decapsulating address, data and control information...and encapsulating data...".

• Motivation to Combine/Modifications: If the apparatus of Claim 1 is obvious, then the method of operating that apparatus (Claim 6) using its inherent functions would also be obvious. The steps of providing the components and utilizing the interface for decapsulating/encapsulating memory access packets are directly dictated by the structure and intended function of the obvious apparatus. It is a well-established principle that if an apparatus is obvious, the method of using that apparatus for its intended purpose is also obvious.

Conclusion for Claim 6: The method steps described in Claim 6 are the inherent functions of the apparatus described in Claim 1. Since the apparatus of Claim 1 is rendered obvious by US20040019704A1 and general knowledge, the method of Claim 6 is likewise obvious.

Claim 11: Computer Readable Media Obviousness

Combination 1: The instructions defining the apparatus and method of Claims 1 and 6, as rendered obvious.

• Claim 11 describes a computer readable media having recorded thereon "instructions defining" the components and functions of the apparatus described in Claim 1 and the method described in Claim 6.

• Motivation to Combine/Modifications: It would have been obvious for a POSA to implement the obvious apparatus and method (from Claims 1 and 6) using computer-readable instructions. The development of software or firmware to control and configure hardware components is a routine engineering task. If the underlying hardware architecture and its operational steps are obvious, then storing instructions to create or control such an architecture on computer-readable media would also be obvious. This is particularly true given the programmable nature implied by "configurable packet-based interfaces" in Sano and the "on the fly programmable bit stream processor" mentioned in US8234483's description.

Conclusion for Claim 11: As the apparatus and method of Claims 1 and 6 are obvious, generating computer-readable instructions to implement or define these obvious structures and functions would be a straightforward and obvious step for a POSA.

Further Considerations for Dependent Claims

The dependent claims (2-5, 7-10, 12-16) add specific features such as a switch interface (Claim 2), programmable bit stream processor implementation (Claim 3), transfer to external packet-switched network (Claim 5), and implementation on FPGA/ASIC (Claims 15, 16).

• Switch Interface (Claim 2): The use of switches to mediate communication between multiple components on a chip or in a system, particularly in packet-switched networks, was well-known in the art. The background of US8234483 mentions "Advanced Switching Interconnect (ASI) switching fabrics" and other hierarchical packet-based interconnection fabrics like "Ethernet, RapidIO, PCI Express or Infiniband". US7352763B2 teaches a "device to receive, buffer, and transmit packets of data in a packet switching network", inherently implying switching capabilities. A POSA would find it obvious to integrate a switch with multiple packet processors on a die to manage traffic between them and an external port, especially in a multi-memory or multi-processor context.
• Programmable Bit Stream Processor (Claim 3): The concept of programmable logic and bit stream processors for protocol handling was also known. US20040019704A1 teaches "configurable packet-based interfaces", which suggests programmability. The general idea of using programmable components (like FPGAs, which are explicitly mentioned in Claim 15) for flexible protocol handling was a known engineering approach to adapt to various standards.
• Transfer to External Packet-Switched Network (Claim 5): The core idea of using packet-switched protocols like Ethernet for I/O and network communication was prevalent. If the on-chip memory access uses a packet-switched serial interface, it is a logical extension to use the same or compatible interface for communication with external packet-switched networks.

In conclusion, the independent claims of US8234483 are rendered obvious by combinations of existing prior art, particularly US20040019704A1, supplemented by common general knowledge in the field regarding serial communication advantages, the memory wall problem, and standard packet processing and switching techniques. The motivations for these combinations are rooted in improving system performance, addressing known bottlenecks, and integrating known elements in a logical manner to achieve predictable results.
