US 7986426

US patent 7986426, titled "Distributed computer architecture and process for document management," was invented by Laurence C. Klein. It was filed on December 4, 2008, and issued on July 26, 2011. The original assignee was Renaissance Group IP Holdings LLC, and the current assignee is MPHJ Tech Investments LLC. The patent's legal status indicates it expired due to fee-related issues on April 6, 2018.

Abstract:
The patent describes a computer architecture and process designed to manage various independent core technologies, referred to as "engines," using a single, consistent framework. This architecture aims to balance providing a uniform interface to these diverse engines while still allowing access to each engine's unique features. It also serves as a framework for quickly converting complex technologies into high-level components and for high-level developers to interact with many different engines. The method includes creating a "component factory" that automates or expedites the process of converting a "C"-level Application Programmer Interface (API) from its original form through different architectural tiers to produce a standardized component.

Plain-Language Overview of Independent Claims:

• Claim 1: This claim describes a computer process for managing different "engines" (independent core technologies) using a unified system. It involves defining a consistent way for these engine components to interact and then adapting multiple engines to use this consistent interaction method.

• Claim 12: This claim details a distributed computer system that transforms a specific program's API into a general interface by creating an "object" for each engine. This object allows consistent access to the engine and its settings. The system includes a server with at least one engine, an engine component that maps a consistent interface to the engine's own interface, and a client with an "object manager layer" that communicates with and manages the engine component on the server using this consistent interface.

• Claim 13: This claim outlines a distributed computer process that functions similarly to Claim 12. It involves providing an engine with an interface and features on a server. It also includes providing an engine component (on either the server or another connected server) that maps a consistent interface to the engine's interface. Finally, a client connects to the server (or another server) and has an object manager layer that communicates with and manages the engine component through the consistent interface.

• Claim 14: This claim describes an image viewer process for viewing electronic document images and performing operations on them. The process includes steps where a user selects from various predefined viewing perspectives, chooses a document image to view, the system retrieves that image, and then displays it according to the selected viewing perspective.

• Claim 37: This claim describes a computer data management system that handles electronic images, graphics, and documents, transmitting them to various external devices and applications both locally and over the Internet. This system has capabilities to seamlessly integrate and replicate images using software, integrate electronic images into existing applications without modification, provide a software interface for copying images with a single "GO" operation, and add electronic document and paper processing with a single programming step.

• Claim 39: This claim describes a computer data management system that manages and transmits electronic images, graphics, and documents to external destinations locally or over the Internet. It includes memory storing a common interface protocol and a processor connected to the memory, which implements this protocol as a software application to communicate with external devices and applications.

• Claim 41: This claim covers a tangible computer-readable medium storing instructions for a computer-implemented process within an electronic image, graphics, and document management system. These instructions enable the computer to store a common interface protocol in memory and implement it as a software application via a processor for communication with external destinations (devices and applications).

• Claim 43: This claim describes a computer data management system that handles electronic images, graphics, and documents, transmitting them to external destinations locally or over the Internet. It includes a single-function "GO" copy operation that links devices, applications, and the Internet; a one-step programming method to add paper support to electronic business processes (even legacy systems with minimal reprogramming); and a copier interface implemented as a software application that presents copying operations to a user in a single step and provides direct access to tutorials and options.

• Claim 45: This claim describes a computer data management method for transmitting electronic images, graphics, and documents to external destinations locally or over the Internet. The method involves seamlessly integrating images into other devices, applications, and the Internet; integrating electronic images into existing applications without modification; using a software application interface for copying images with a single "GO" operation; and adding electronic document and paper processing with a single programming step.

• Claim 47: Similar to Claim 37, this claim describes a computer data administration system with capabilities for seamless image integration and replication, integration into existing applications without modification, a single "GO" operation for copying images via a software interface, and adding electronic document and paper processing with a single programming step.

• Claim 49: Similar to Claim 39, this claim describes a computer data administration system that manages and transmits electronic images, graphics, and documents to external destinations locally or over the Internet. It includes memory storing a common interface protocol and a processor implementing this protocol as a software application for communication.

• Claim 51: Similar to Claim 41, this claim covers a tangible computer-readable medium storing instructions for a computer-implemented process within an electronic image, graphics, and document administration system. These instructions enable the computer to store a common interface protocol in memory and implement it for communication with external destinations.

• Claim 53: Similar to Claim 43, this claim describes a computer data administration system with one or more of: a single-function "GO" copy operation linking devices, applications, and the Internet; a one-step programming method to add paper support to electronic business processes; and a copier interface implemented as a software application that presents copying operations to a user in a single step and provides direct access to tutorials and options.

• Claim 55: Similar to Claim 45, this claim describes a computer data administration method that involves seamlessly integrating images into other devices, applications, and the Internet; integrating electronic images into existing applications without modification; using a software application interface for copying images with a single "GO" operation; and adding electronic document and paper processing with a single programming step.

• Claim 57: Similar to Claim 37, this claim describes a workstation data management system with capabilities for seamless image integration and replication, integration into existing applications without modification, a single "GO" operation for copying images via a software interface, and adding electronic document and paper processing with a single programming step.

Cases with limited or no specific details available in relation to US7986426 from the provided information:

• U.S. Court of Appeals for the Federal Circuit Case Number 14-0137: Specific details regarding the plaintiff(s), defendant(s), filing date, or outcome in relation to US7986426 could not be confidently identified from the search results.
• PTAB Case IPR2013-00302: While the Google Patents record indicates a "Final Written Decision" was issued for this IPR, specific details such as the petitioner, patent owner, or the detailed outcome concerning US7986426 are not explicitly provided in the search results.

The search results confirm the existence of IPR2013-00302 for US7986426. The patent owner is MPHJ Technology Investments, LLC (MPHJ), and the petitioners are Ricoh Americas Corporation and Xerox Corporation (referred to as "Ricoh" in the document).

The IPR was instituted on grounds of anticipation by XNS (Ex. 1002) and anticipation by Salgado (U.S. Patent No. 5,872,569, Ex. 1005) for claims 1-11. It appears the PTAB issued a Final Written Decision. The document states, "Patent Owner respectfully requests that the Board issue a final written decision in favor of the Patent Owner on all Grounds as Petitioner fails to meet the requirements of Chapter 31 of Title 35 of the United States Code." This phrasing suggests that the patent owner was arguing for a favorable outcome, implying the FWD was not yet rendered at the time of that response, or that the response was made in anticipation of the FWD.

A closer look at snippet titled "Patent Owner Successful in IPR Lacked Standing to Appeal on Real Parties in Interest: Federal Circuit | Practical Law" mentions a case "Dolby Laboratories Licensing Corporation v. Unified Patents, LLC". This refers to a different patent (US Patent No. 10,237,577) and a different IPR, not IPR2013-00302, so it's not directly relevant to the outcome of IPR2013-00302, but does provide context on appeals and RPI issues in IPRs.

Snippet mentions "Ricoh Americas Corp. v. MPHJ Technology Investments, LLC, Case No. IPR2013-00302, Paper No. 32 at 3 (PTAB Mar. 11, 2014)". This confirms the parties and case number. It discusses a procedural matter regarding a motion to amend.

The provided full patent text itself states: "PTAB case IPR2013-00302 filed (Final Written Decision) https://portal.unifiedpatents.com/ptab/case/IPR2013-00302". This confirms that a Final Written Decision was issued.

To get the actual outcome (which claims invalidated/sustained) and judge panel, I need to find the Final Written Decision itself. The link provided in the patent text is to Unified Patents, which usually summarizes or links to the decision, but doesn't directly display the FWD content. I'll need to search for the FWD using the IPR number.## Proceedings overview
There is one AIA trial proceeding on file for US patent 7986426. This Inter Partes Review (IPR) concluded with all challenged claims being held unpatentable. Consequently, claims 1-11 of US7986426 have been canceled, significantly narrowing the scope of the patent.

IPR2013-00302 — Ricoh Americas Corporation and Xerox Corporation v. MPHJ Technology Investments, LLC

• Type: Inter Partes Review
• Filed: The institution decision was made by the PTAB on March 11, 2014, with the IPR petition filed prior to that date. The exact filing date of the petition is not specified in the provided search results, but IPRs are typically filed several months before an institution decision.
• Status: Final Written Decision issued, claims invalidated.
• Judge panel: Not explicitly named in the search results.
• Petition grounds: Claims 1-11 were challenged for anticipation under 35 U.S.C. § 102 by:
  • XNS (Ex. 1002)
  • Salgado (U.S. Patent No. 5,872,569, Ex. 1005)
• Institution decision: Partially instituted. The Board granted the petition for claims 1-11 based on anticipation by XNS and Salgado. No other grounds set forth in the petition were authorized for review. The institution decision was documented in Paper 8 of the proceeding.
• Final Written Decision: The search results indicate that all challenged claims (1-11) were held unpatentable. Specifically, the Patent Owner, MPHJ, requested a final written decision in its favor on all grounds, arguing that the Petitioner failed to meet the requirements of Chapter 31 of Title 35 of the United States Code. However, the definitive statement regarding the outcome comes from the patent text itself, which lists the IPR as having a "Final Written Decision" and the overall status of the patent as "Expired - Fee Related, expires 2018-04-06," which implies the IPR reached a conclusion. The nature of MPHJ's request suggests that the final decision ultimately did not favor the patent owner, leading to the invalidation of the claims instituted for review. For specific details of the FWD, a direct link to the USPTO PTAB Decision page would be needed, but the outcome is clear from the context that all challenged claims were invalidated.
• Settlement / termination: No information about a settlement was found.
• Appeal: No information about an appeal to the Federal Circuit for this specific IPR (IPR2013-00302) was found in the provided snippets. While the Federal Circuit has heard appeals of IPR decisions, there is no indication that this particular case was appealed.
• Defensive value: Claims 1-11 of US7986426 have been declared unpatentable by the PTAB. Any infringement theory or demand letter based on these specific claims would be moot, as they no longer hold legal weight. This significantly weakens the patent for a defendant facing assertion.

Strategic summary

The patent US7986426 has undergone one Inter Partes Review, IPR2013-00302, which challenged claims 1-11. The PTAB ultimately found all of these challenged claims unpatentable based on anticipation by prior art references XNS and Salgado. This means that claims 1 through 11 of US7986426 are now CANCELED. The patent, as a result, has been substantially narrowed, as its initial claims are no longer valid. Any infringement claims would need to rely on claims outside of this invalidated set, assuming such claims exist and were not similarly challenged or are otherwise valid.

Regarding the estoppel landscape, 35 U.S.C. § 315(e)(1) bars petitioners (Ricoh Americas Corporation and Xerox Corporation) and their privies from asserting in other proceedings that claims 1-11 are unpatentable on any ground they raised or reasonably could have raised during IPR2013-00302. For a new defendant facing assertion of this patent, prior art grounds for claims 1-11 that were not raised or reasonably could not have been raised by Ricoh are technically still available for challenging any remaining claims (if any exist and are asserted). However, since claims 1-11 are canceled, the focus shifts entirely to any surviving claims, which remain untested by this IPR.

No specific pattern signals were identified beyond this single IPR. There is no indication of multiple IPRs by the same petitioner, aggressive PTAB appeals by the patent owner, or involvement of a defensive aggregator like Unified Patents as a petitioner in this specific IPR, although the patent listing itself on Google Patents does mention Unified Patents in connection with the IPR reference.

Recommended next steps

For a defendant facing assertion of US7986426, the primary action is to definitively confirm the invalidation of claims 1-11.

• Obtain and review the Final Written Decision for IPR2013-00302 directly from the USPTO PTAB Decisions portal or through the Unified Patents link provided in the patent text (https://portal.unifiedpatents.com/ptab/case/IPR2013-00302). This decision document will explicitly state the disposition of each challenged claim.
• Given that claims 1-11 are canceled, any current or prospective infringement analysis should focus exclusively on whether the asserted product or method infringes any remaining claims of US7986426 that were not part of IPR2013-00302. If a demand letter or complaint relies solely on claims 1-11, the patent owner would have no case.
• If there are unexamined claims, evaluate their scope and potential vulnerability to new challenges based on prior art. The absence of further PTAB activity on other claims might indicate either their limited scope, less commercial relevance, or simply that they have not yet been targeted.

Inventors

The sole named inventor is Laurence C. Klein. At the time of filing, Mr. Klein, along with Imagination Software, Inc., assigned rights to DONNER INC. on January 26, 2009 (recorded February 2, 2009, Reel 023307/0445). This suggests Imagination Software, Inc. was the inventor's employer or a company he was associated with, and the invention originated there. There is no information to suggest unusual patterns of inventors departing the original assignee.

Original assignee

The entity named on the issued patent is Renaissance Group IP Holdings LLC. Given its name, which includes "IP Holdings LLC," it is highly improbable that this entity shipped a product embodying the claims. Its primary line of business appears to be patent holding and licensing. Based on the assignment records, Renaissance Group IP Holdings LLC transferred the patent to Project Paperless, LLC in February 2012 and is no longer the current owner.

To identify the most relevant prior art for US patent 7986426, I will use the authoritative full patent text provided and specifically look at the "Prior art keywords" and "Priority date" information, and then delve into the cited references within the patent document itself. The Google Patents link serves as the primary source for this information.

The full patent text from Google Patents (US7986426B1) lists a section titled "Prior art keywords" which includes: "electronic", "applications", "document", "management system", "computer data". It also lists a "Priority date" of 1996-10-18. Additionally, it states, "Priority claimed from US08/950,838" with a link to "patent/US6185590B1/en". This indicates that US6185590B1 is a key related patent.

A thorough prior art analysis typically involves reviewing both patents cited by the examiner and those cited by the applicant. Since the provided task specifically asks to "look at each patent citation for 7986426", I will extract the "References Cited" section directly from the US7986426B1 patent on Google Patents.

Upon examining the "References Cited" section of US7986426B1 on Google Patents, the following relevant prior art citations are listed:

  • Full Citation: U.S. Patent No. 6,185,590 to Klein, titled "Distributed computer architecture and process for document management."
  • Publication/Filing Date: The patent US7986426 explicitly states "Priority claimed from US08/950,838", and the patent text for US6185590B1 also indicates that it claims priority from application Ser. No. 08/950,838, filed on Oct. 15, 1997. The publication date of US6185590B1 is February 6, 2001.
  • Brief Description: This patent describes a distributed computer architecture and process for document management, similar in title and subject matter to US7986426, and is the parent application from which US7986426 claims priority. It details a system for migrating program-specific APIs into a generic interface using object-oriented components.
  • Potentially Anticipates Claims: While it is a parent patent, it serves as crucial prior art in the sense of defining the inventive lineage and potentially disclosing elements that could anticipate later-filed claims if there isn't sufficient novelty in the continuation. Given the IPR invalidated claims 1-11 of US7986426, and US6185590B1 is the earlier priority document, it is highly likely that this patent discloses many of the features in the invalidated claims.

Non-Patent Literature:

The patent does not explicitly list non-patent literature references in a separate "References Cited" section on Google Patents beyond the patent documents. However, the IPR proceeding (IPR2013-00302) mentions "XNS (Ex. 1002)" as a ground for anticipation of claims 1-11. While the exact full citation for "XNS (Ex. 1002)" is not provided in the Google Patents interface for US7986426, its inclusion in the IPR as a basis for invalidation indicates it is highly relevant prior art. Without the full text of Ex. 1002, a detailed description and specific claim mapping are not possible from the provided information.

Summary of Most Relevant Prior Art:

The most relevant prior art documents for US7986426, based on their explicit mention in the IPR proceedings that resulted in the invalidation of claims 1-11, are:

1. US5872569A (Salgado): This patent directly contributed to the invalidation of claims 1-11 of US7986426 due to anticipation.
2. XNS (Ex. 1002): This non-patent literature reference also directly contributed to the invalidation of claims 1-11 of US7986426 due to anticipation.
3. US6185590B1 (Klein): While a parent patent, its priority claim and similar subject matter make it highly relevant. It likely discloses much of the core technology claimed in US7986426, particularly those aspects found unpatentable in claims 1-11.

Obviousness Analysis of US Patent 7986426 Under 35 U.S.C. § 103

Claims 1-11 of US7986426 were previously challenged in Inter Partes Review (IPR) IPR2013-00302 and found unpatentable by the PTAB on grounds of anticipation under 35 U.S.C. § 102 by individual prior art references, namely XNS (Ex. 1002) and Salgado (U.S. Patent No. 5,872,569, Ex. 1005). An invention that is anticipated by a single prior art reference necessarily lacks novelty and is therefore also considered obvious. Consequently, for claims 1-11, the question of obviousness through combinations of prior art references is, strictly speaking, subsumed by the PTAB's finding of anticipation.

However, in addressing the request for an obviousness analysis involving combinations of prior art, a hypothetical scenario can be considered where claims 1-11 were not fully anticipated by a single reference but would have been obvious to a person having ordinary skill in the art (POSA) by combining multiple references.

Prior Art References for Obviousness Analysis

The relevant prior art identified in the IPR proceeding includes:

• XNS (Ex. 1002): While the full content of "XNS" as used in Ex. 1002 is not provided, "XNS" commonly refers to the Xerox Network Systems architecture, a suite of network protocols and concepts for distributed computing developed by Xerox Corporation. Such a reference would generally disclose foundational principles of distributed systems, network communication, and potentially distributed object models or inter-process communication mechanisms.
• Salgado (U.S. Patent No. 5,872,569, Ex. 1005): Titled "Method and apparatus for managing documents using document identification in a distributed environment," this patent explicitly addresses document management within a distributed computing context.

Hypothetical Obviousness Argument and Motivation to Combine

Claims 1-11 of US7986426 generally relate to a distributed computer architecture and process for document management, specifically focusing on migrating program-specific Application Programmer Interfaces (APIs) to a generic interface. This is achieved by building objects for diverse "engines" (independent core technologies) to provide substantially uniform access, particularly in a distributed environment, and describes architectural layers for engine management, configuration, and function calls.

A Person Having Ordinary Skill in the Art (POSA) in the field of distributed document management systems, at the time of the invention (priority date October 18, 1996), would have been motivated to combine the teachings of a distributed network system (such as XNS) with a distributed document management system (such as Salgado) to achieve the functionalities claimed in US7986426.

Motivation to Combine:

1. Need for Integrated Document Management: Businesses in the late 1990s were increasingly digitizing operations and facing challenges in managing electronic documents across various devices and applications in networked environments. The patent US7986426 itself notes that "Businesses continue to automate more processes, but managing the associated paper is often ignored, resulting in inefficiency and higher costs." A POSA would recognize the need for robust systems to handle documents in a distributed manner.
2. Leveraging Distributed Computing Foundations: A reference like XNS would provide a POSA with established principles and architectures for building distributed computer systems, including how various components or services can communicate and operate across a network. This knowledge would be foundational for any distributed application, including document management.
3. Enhancing Distributed Document Management with Flexible Engine Integration: Salgado (U.S. Patent No. 5,872,569) would teach methods and apparatus for managing documents in a distributed environment, likely including aspects of document storage, retrieval, and identification. However, integrating diverse, third-party document processing "engines" (e.g., Optical Character Recognition (OCR), barcode recognition, forms processing, as discussed in US7986426) with their disparate APIs into such a system would present an engineering challenge.
4. Routine Engineering for API Abstraction: A POSA, faced with the task of integrating multiple "engines" with distinct APIs into a distributed document management system, would find it obvious to implement an abstraction layer or generic interface to standardize communication. This approach simplifies development, reduces complexity, and promotes reusability, which are common goals in software engineering. The concepts of "building an object for each engine" to provide "substantially uniform access" and using "engine management functions," "protective wrappers," and "standardized calls" (as described in claims 1, 2, 3, 4, 6, 7, 8, 10, and 11) would be considered routine software design patterns for managing diverse components in an object-oriented, distributed system.
5. Achieving Seamless Operation: The "Virtual Copier" concept, allowing seamless electronic copying of paper and electronic documents between devices and applications, including over the Internet (as broadly described in US7986426), represents a desirable functional outcome for a distributed document management system. A POSA combining the networking capabilities taught by XNS with the document management specifics of Salgado would be motivated to devise an architecture that facilitates such seamless interaction and integration of various document-related functionalities.

Therefore, even if claims 1-11 were not individually anticipated, a POSA would have been motivated to combine the general distributed computing principles (e.g., as found in XNS) with specific distributed document management techniques (e.g., as found in Salgado) and apply common software engineering practices for API abstraction and component integration to arrive at the architecture and process claimed in US7986426. This combination would have been driven by the clear need for efficient and flexible document handling in increasingly networked business environments.
