US Patent 7664707: System and method for handling peripheral connections to mobile devices

• Title: System and method for handling peripheral connections to mobile devices
• Current Assignee: Malikie Innovations Ltd
• Inventors: Neil P. Adams, Herbert A. Little, Christopher E. S. Pattenden, Michael K. Brown, Michael G. Kirkup
• Filing Date: 2005-02-25 (Application number US11/067,239)
• Issue Date: 2010-02-16
• Abstract: Systems and methods for establishing a data connection between a mobile device and a peripheral are described. The mobile device is configured to determine whether to handle user approval of the data connection between the mobile device and the peripheral. An input mechanism is provided through the mobile device for the user to provide input. This input is then used to determine whether to approve the data connection between the mobile device and the peripheral.

Plain-Language Overview of Independent Claims:

• Claim 1 (Independent): This method describes how a mobile device handles a data connection request from a peripheral. It involves the mobile device receiving a request from the peripheral to manage the approval process itself. The mobile device then presents an input method to the user to get their approval for the connection. Based on this user input, the mobile device decides whether to allow the data connection. A key aspect is that the peripheral itself is unable to show an input prompt to the user for this approval.
• Claim 2 (Independent): Similar to Claim 1, this method also describes a mobile device handling a data connection request from a peripheral. The mobile device receives a request from the peripheral to manage the approval. The mobile device then provides an input mechanism for the user to submit input, which the mobile device uses to decide on approving the data connection. The distinction in this claim is that the peripheral is specifically unable to receive user input for the approval process.

CAFC 2026 Dockets:
As of April 26, 2026, searches of CAFC 2026 dockets did not return any specific litigation or appeals directly involving US patent 7664707. While other patent numbers were mentioned in CAFC decisions from January, March, and July 2026, patent 7664707 was not among them.

As of April 26, 2026, there is no known litigation specifically involving US patent 7664707.

The search results show litigation involving "Malikie Innovations Ltd" (the current assignee of US7664707B2) and "Research in Motion Ltd" (the original assignee). However, none of these cases directly assert US7664707B2.

For example:

• Malikie Innovations Ltd. was involved in a patent infringement lawsuit against SAP America, Inc. (Case No. 2:25-cv-00946, E.D. Texas, filed September 12, 2025, dismissed with prejudice December 15, 2025). The patents asserted in this case were US7685396B2, US9552498B2, US7496606B2, and US10503742B2.
• Malikie Innovations Limited filed a patent infringement lawsuit against Xiaomi Corporation and other Xiaomi entities at the Munich Local Division of the Unified Patent Court (UPC_CFI_1733/2025, filed November 25, 2025). This case alleges infringement of a 5G patent, EP3797535, "Emergency services handling."
• Unified Patents challenged a Malikie Innovations patent (US10778989) related to a video codec method by filing an ex parte reexamination proceeding on May 2, 2025.
• Research In Motion, Ltd. (RIM) was found liable for $147 million in damages for infringing patents held by Mformation Technologies (filed October 2008, verdict July 2012). This case involved wireless management of devices and specifically mentioned BlackBerry Enterprise Server (BES) software. The specific patent numbers for this case were not provided in the search result, but it did not mention US7664707.
• Earlier, in 2006, Research In Motion settled a patent dispute with NTP, Inc. for $612.5 million. The case was filed in November 2001 in the U.S. District Court for the Eastern District of Virginia (Civil Action No. 3:01cv767). The patents-in-suit included US Patents Nos. 5,436,960; 5,625,670; 5,819,172; 6,067,451; and 6,317,592. US7664707 was not among these.

Therefore, based on the provided search results, there is no known litigation directly involving US patent 7664707.

Proceedings overview

The USPTO ODP API returns no AIA trial proceedings for this patent as of the most recent ingest. Web search did not surface any specific AIA trial proceedings (IPR, PGR, or CBM) directly involving US Patent 7,664,707. Therefore, there is no PTAB activity on file for this patent. This gives a defendant no immediate defensive posture based on PTAB invalidation.

Strategic summary

As there are no PTAB trial proceedings (IPR, PGR, or CBM) on file for US Patent 7,664,707, all claims (claims 1, 2, and 3) remain untested and presumably valid from a PTAB perspective. This means there are no canceled or sustained claims to report, and all claims are currently untested in an AIA trial setting.

Regarding the estoppel landscape, since no IPRs have been filed, there are no prior-art grounds that would be barred under § 315(e)(2) for future petitioners. All prior-art grounds remain available for a potential future IPR challenge.

There are no pattern signals to discern regarding multiple IPR filings, patent owner appeal aggressiveness, or involvement of defensive aggregators like Unified Patents, as no such proceedings exist for this patent. Malikie Innovations Ltd. (the current assignee) is known as a non-practicing entity that acquired a large patent portfolio from BlackBerry Ltd., and has been active in patent assertion, including against D-Link Corp. and Nintendo, involving other patents from its portfolio. While Malikie Innovations has been involved in litigation and other patent challenges for other patents in its portfolio, there is no indication of such activity for US7664707 specifically.

Recommended next steps

If you are a defendant facing assertion of US Patent 7,664,707, the absence of PTAB activity means that the validity of the claims has not been tested in an AIA trial. Therefore, an IPR filing remains a viable defensive option. Your next steps could include:

• Conducting a thorough prior art search: Since the claims are untested, a robust prior art search is crucial to identify potential grounds for an IPR petition under 35 U.S.C. §§ 102 or 103.
• Considering an IPR petition: If strong prior art is found, filing an IPR petition could be a strategic move to challenge the validity of claims 1, 2, and 3. You would need to analyze the specific language of the claims and the identified prior art to determine the most effective grounds.
• Monitoring for future PTAB activity: Keep a close watch on the PTAB E2E system for any newly filed petitions against US Patent 7,664,707, as such filings could impact your defensive strategy.

NPE / troll-pattern signals

1. Shell-entity transfer — present. The patent moved from BlackBerry Limited, an operating company, to OT Patent Escrow, LLC, and then to Malikie Innovations Limited (Malikie). Malikie Innovations is described as an "IP holding company associated with the former BlackBerry technology portfolio, active in patent assertions across multiple sectors" and a "subsidiary of Irish patent monetization firm Key Patent Innovations Limited (KPI)". Malikie's portfolio relates to licensing various technologies. This indicates a transfer to a licensing-only entity that does not produce products embodying the claims. The transfers are recorded on reel 063471/0474 (BlackBerry to OT Patent Escrow, executed 2023-04-27) and reel 064015/0001 (OT Patent Escrow to Malikie, executed 2023-06-16).
2. Known asserter in the chain — present. Malikie Innovations Limited is the current assignee. Malikie Innovations is recognized as a non-practicing entity (NPE) and a subsidiary of Key Patent Innovations, a patent monetization firm. Malikie actively engages in patent enforcement, including litigation and licensing, across various technology sectors. They have been involved in lawsuits against companies like Acer, ASUSTek, Nintendo, Canon, D-Link, OPPO, and Samsung.
3. Repeat correspondent across the chain — present. Brent D. Reynolds of Law Office of Brent D. Reynolds (P.O. Box 10077, Berkeley, CA 94709) is listed as the correspondent for the assignments from BlackBerry to OT Patent Escrow (reel 063471/0474, executed 2023-04-27) and subsequent transfers involving OT Patent Escrow and Malikie Innovations Limited (reel 064015/0001, executed 2023-06-16, 2023-06-19, 2023-09-05). This recurring correspondent across multiple transfers to an NPE family is a strong signal.
4. Cascading transfers — present. There are multiple consecutive assignments within a short period in 2023. The transfer from BlackBerry to OT Patent Escrow occurred on 2023-04-27 (reel 063471/0474), followed by the assignment from OT Patent Escrow to Malikie Innovations Limited on 2023-06-16 (reel 064015/0001), and a corrective direct assignment from BlackBerry to Malikie on 2023-06-19 (reel 064015/0001). Further corrective assignments occurred on 2023-09-05 (reel 064015/0001). These transactions, all within a few months, represent cascading transfers.
5. Pre-litigation transfer — unclear. While Malikie Innovations is actively involved in litigation with other patents, and has been since March 2024, there is no known litigation specifically involving US7664707. Therefore, it is unclear if these transfers were specifically "pre-litigation" for this particular patent.
6. Bankruptcy fire-sale — not present. Research in Motion Ltd. (now BlackBerry Limited) did not file for bankruptcy. Instead, it strategically shifted its business focus from hardware to software and services and sold its non-core patent portfolio to Malikie Innovations.
7. Privateering — unclear. While BlackBerry sold a significant portion of its patent portfolio to Malikie Innovations, the current information does not explicitly state that Malikie is asserting this patent on BlackBerry's behalf against competitors. It's a general divestment of non-core assets.
8. Defensive aggregator (anti-NPE) — not present. The chain ends with Malikie Innovations Limited, a known patent monetization firm.

Verdict

NPE — high confidence

The assignment chain clearly demonstrates a transfer from an operating company (BlackBerry Limited) to a known patent monetization firm (Malikie Innovations Limited), a subsidiary of Key Patent Innovations (reel 063471/0474 executed 2023-04-27 and reel 064015/0001 executed 2023-06-16). This is further supported by the presence of a repeat correspondent, Brent D. Reynolds, across multiple recent transfers (reel 063471/0474 and reel 064015/0001), and cascading transfers within a short timeframe in 2023, all indicative of a structured patent assertion strategy.

Most Relevant Prior Art for US Patent 7,664,707

Here's an analysis of the most relevant patent citations for US Patent 7,664,707, including their publication/filing dates, brief descriptions, and potential anticipation of claims under 35 U.S.C. § 102.

Patent Citations:

1. WO2000072506A1

   • Full Citation: WO2000072506A1, "Method and apparatus for initializing secure communications among, and for exclusively pairing wireless devices," International Business Machines Corporation.
   • Publication Date: 2000-11-30
   • Description: This patent describes a method for securely initializing communications and pairing wireless devices. It focuses on establishing a secure link for data exchange between devices.
   • Potential Anticipation (35 U.S.C. § 102): This reference could potentially anticipate aspects of claims 1 and 2 related to establishing a data connection between devices, particularly if the "pairing" process inherently involves user approval or a mechanism for approving data transfer. The patent's emphasis on "secure communications" and "initializing" connections suggests a process that might involve user interaction or implicit approval for the connection to proceed. However, it's not explicitly stated whether one device handles the approval process when the other cannot provide a prompt/input.

2. WO2001088677A2

   • Full Citation: WO2001088677A2, "Apparatus and method for secure object access," Stefaan De Schrijver.
   • Publication Date: 2001-11-22
   • Description: This patent focuses on an apparatus and method for secure access to objects, likely involving data or resources, between devices.
   • Potential Anticipation (35 U.S.C. § 102): Similar to WO2000072506A1, this patent's focus on "secure object access" implies a connection and potentially an approval process before access is granted. If the "apparatus" or "method" describes one device initiating access and another (e.g., a mobile device) explicitly handling the approval due to limitations of the requesting device, it could potentially anticipate claims 1 and 2.

3. US7333946B1

   • Full Citation: US7333946B1, "Ticketing with printing option," Nokia Corporation.
   • Publication Date: 2008-02-19
   • Filing Date: 2000-09-01
   • Description: This patent describes a system for ticketing with a printing option, likely involving a mobile device interacting with a printer or a ticketing terminal.
   • Potential Anticipation (35 U.S.C. § 102): If the ticketing and printing process involves a mobile device connecting to a peripheral (e.g., a printer) and the mobile device explicitly handles a user approval step for the connection or data transfer (e.g., approving the print job or connection to the printer), and the peripheral itself lacks the ability to prompt for or receive input, it could potentially anticipate claims 1 and 2. The concept of a mobile device initiating and controlling an action with a peripheral, which might lack full input/output capabilities, is relevant.

4. US20020062385A1

   • Full Citation: US20020062385A1, "Negotiated wireless peripheral systems," Dowling Eric Morgan.
   • Publication Date: 2002-05-23
   • Description: This application describes systems for negotiating connections with wireless peripherals.
   • Potential Anticipation (35 U.S.C. § 102): The term "negotiated" suggests a process for establishing a connection, which could involve an approval step. If this negotiation process includes scenarios where a mobile device handles user approval for a peripheral that cannot perform this function itself, it could potentially anticipate claims 1 and 2.

5. GB2370383A

   • Full Citation: GB2370383A, "Access to personal computer using password stored in mobile phone," Hewlett Packard Co.
   • Publication Date: 2002-06-26
   • Filing Date: 2000-12-22
   • Description: This patent describes a system where a mobile phone's stored password is used to access a personal computer.
   • Potential Anticipation (35 U.S.C. § 102): This reference is highly relevant. It directly describes a mobile device (mobile phone) being used to provide a password for access to another device (personal computer). If the personal computer (peripheral) is in a state where it cannot prompt for the password or receive it directly from the user (e.g., if the PC is locked or in a specific mode), and the mobile phone is explicitly used to provide the input that approves the connection or access, then it could potentially anticipate claims 1, 2, and 3. Claim 1 specifies the peripheral not being capable of providing an input prompt, and Claim 2 specifies the peripheral not being capable of receiving an input. If the mobile phone is the mechanism through which the user provides the password to the PC, this could align.

6. US20040092231A1

   • Full Citation: US20040092231A1, "Communication system and method, information processing terminal and method, and information processing apparatus and method," Yuji Ayatsuka.

   • Description: This is a continuation-in-part or related application to US20040092231A1, also describing a communication system with information processing terminals.
   • Potential Anticipation (35 U.S.C. § 102): Given its relation to US20040092231A1, it would likely cover similar ground. If it teaches the mobile device handling user approval for a peripheral connection when the peripheral lacks the ability to prompt for or receive user input, it could anticipate claims 1, 2, and 3.

10. US7337229B2

    • Full Citation: US7337229B2, "Method and apparatus for authorizing internet transactions using the public land mobile network (PLMN)," Telefonaktiebolaget Lm Ericsson (Publ).
    • Publication Date: 2008-02-26
    • Filing Date: 2001-11-08
    • Description: This patent describes a method and apparatus for authorizing internet transactions using a mobile network.
    • Potential Anticipation (35 U.S.C. § 102): While focusing on "internet transactions," the underlying principle of authorization involves a user approving an action. If this authorization process, when mediated by a mobile device for a peripheral, incorporates the mobile device handling the approval when the peripheral has input/output limitations, it could potentially anticipate claims 1, 2, and 3.

11. US20030095521A1

    • Publication Date: 2005-02-24
    • Description: This application describes a wireless printer access point designed for visitor safety.
    • Potential Anticipation (35 U.S.C. § 102): The concept of "visitor safe" implies access control and likely an approval process. If a mobile device connects to this wireless printer access point (peripheral) and the mobile device handles the user approval for printing (a data connection), particularly when the access point itself is designed with limited user interface for security reasons (i.e., not capable of providing a prompt or receiving input), it could potentially anticipate claims 1, 2, and 3. This reference's publication date is February 24, 2005, which is before the filing date of US7664707 (February 25, 2005), making it a direct prior art reference. This is a critical point.

Summary of Most Relevant Prior Art & Potential Anticipation:

Based on the descriptions, GB2370383A (Access to personal computer using password stored in mobile phone) and US20050044479A1 (Visitor safe wireless printer access point) appear to be particularly strong candidates for anticipating the claims of US7664707.

• GB2370383A directly describes using a mobile device for password entry to access a PC, which aligns closely with the core inventive concept of a mobile device handling user input for a peripheral connection, especially if the PC is a peripheral lacking full input/output capabilities for that specific authentication.
• US20050044479A1 is particularly significant due to its publication date of February 24, 2005, which is one day prior to the filing date of US7664707 (February 25, 2005). This makes it direct prior art under 35 U.S.C. § 102(a). The concept of a "visitor safe wireless printer access point" implies controlled access and an approval process where the mobile device likely handles user authentication or approval, and the access point (peripheral) itself would inherently have limited or no user input/prompt capabilities for security and simplicity. This scenario directly maps to the conditions set forth in claims 1, 2, and 3.

Other references like WO2000072506A1, WO2001088677A2, EP1239630A2, US7296149B2, and US20040162027A1 also show strong potential, as they discuss secure communication, authentication, pairing, and user selection in the context of device connections, often involving mobile devices and other apparatuses. A detailed examination of their specific disclosures regarding which device handles user input for connection approval when the peripheral is limited would be necessary for a definitive assessment.

Obviousness Analysis under 35 U.S.C. § 103

A patent claim is considered obvious if "the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains." This analysis involves several factual inquiries, including determining the scope and content of the prior art, ascertaining the differences between the prior art and the claims, and resolving the level of ordinary skill in the pertinent art. A motivation to combine prior art references is crucial for establishing obviousness. This motivation can stem from the knowledge of those skilled in the art, from the prior art references themselves, or from the nature of the problem to be solved.

The effective filing date for US Patent 7,664,707 is April 30, 2004, based on its priority claim to U.S. Provisional Application Ser. No. 60/566,774. Therefore, the obviousness analysis considers what would have been obvious to a person having ordinary skill in the art (PHOSITA) before this date.

Obviousness Combinations and Rationale

The independent claims of US Patent 7,664,707 center on a mobile device handling user approval for a data connection with a peripheral, specifically when the peripheral itself cannot provide an input prompt or receive user input for approval.

A PHOSITA in the field of mobile device communications and security, as of April 30, 2004, would have been aware of the need for secure connections between mobile devices and peripherals, as well as various methods for user authentication and managing device access.

Combination 1: GB2370383A in view of common general knowledge and the problem of peripherals lacking input capabilities.

• GB2370383A (Hewlett Packard Co): This patent describes "Access to personal computer using password stored in mobile phone." This reference clearly demonstrates the concept of a mobile phone being used for authentication, specifically involving a password. While it focuses on accessing a PC using the mobile phone, it establishes the idea of the mobile device acting as an authentication factor.
• Motivation to Combine: A PHOSITA, recognizing the security risks associated with peripheral connections to mobile devices (as highlighted in the background of US7664707) and the varying capabilities of different peripherals, would have been motivated to adapt existing mobile device security features to address the problem of peripherals lacking user input mechanisms. If a peripheral (e.g., a memory card, a specialized hardware crypto token, or even some early camera models, as listed in US7664707's description) lacked a display or keyboard, the logical solution for secure connection approval would be to shift that responsibility to the mobile device itself, leveraging its inherent input/output capabilities. GB2370383A provides the foundational concept of a mobile device handling password-based authentication for external access. Extending this to a scenario where the mobile device itself prompts for the password to approve a peripheral's connection is a predictable application of known security principles to a known problem (peripheral security). The desire to improve the security and usability of peripheral connections, especially for devices without rich user interfaces, would provide the motivation.

Application to Claims 1 and 2:

• Claim 1: The combination would render Claim 1 obvious because GB2370383A teaches using a mobile device for password-based access, and a PHOSITA would readily understand that if a peripheral "is not capable of providing an input prompt," the mobile device could handle this by providing its own input mechanism (prompting for the password on its screen and accepting input via its keyboard).
• Claim 2: Similarly, for Claim 2, if the peripheral "is not capable of receiving an input," the mobile device taking on the responsibility of providing an input mechanism and receiving the user's input (e.g., a password) to approve the connection is a logical and obvious design choice to ensure security in such a scenario.

Combination 2: US20020062385A1 (Negotiated wireless peripheral systems) in view of EP1239630A2 (Method and apparatus for increasing the security of wireless data services) or US7296149B2 (Secure user and data authentication over a communication network).

• US20020062385A1 (Dowling Eric Morgan): This reference discusses "Negotiated wireless peripheral systems," implying that a connection between a mobile device and a peripheral might involve some form of handshake or agreement. This sets the stage for dynamic handling of connection parameters.
• EP1239630A2 (Telefonaktiebolaget L M Ericsson (Publ)) or US7296149B2 (Ubs Ag): Both of these references address increasing the security of wireless data services or secure user and data authentication over a communication network. They would make a PHOSITA aware of the general need for secure data connections and various methods for authentication.
• Motivation to Combine: A PHOSITA faced with the problem of securing connections in "negotiated wireless peripheral systems" (US20020062385A1), where the peripheral might not have the necessary input/output capabilities for user approval, would be motivated to integrate existing security and authentication mechanisms (from EP1239630A2 or US7296149B2) into the mobile device's control. The unpredictable nature of peripheral capabilities in "negotiated" systems would prompt a PHOSITA to centralize security approval on the more robust mobile device. The general goal of enhancing security for data connections, particularly with the rise of various peripherals, would drive this combination. It would be an obvious design choice to ensure that even simple peripherals could establish secure connections by delegating the user approval step to the mobile device, where advanced authentication methods (like passwords) could be easily implemented.

Application to Claims 1 and 2:

• The combination teaches the principle of a mobile device being responsible for security in a peripheral connection scenario, especially when the peripheral has limited capabilities. The "negotiation" aspect in US20020062385A1 could easily encompass the peripheral requesting the mobile device to handle the approval. The security mechanisms from EP1239630A2 or US7296149B2 would provide the actual input and determination steps on the mobile device.

Combination 3: US20040249994A1 (Microsoft Corporation - Method and system for providing a peripheral service to a host computing device) in view of the background discussion in US7664707 regarding the attacker scenario.

• US20040249994A1: This patent application discusses providing a "peripheral service to a host computing device." While it focuses on a host computer, the underlying principle of managing services for a peripheral is relevant.
• Background of US7664707: The background explicitly states: "If the user has a Trojan horse application on their handheld, then an attacker can pickpocket the device, attach a laptop, connect with the Trojan horse application, and then the application can transfer the user's data from the device or inject a rogue application. Accordingly, some type of approval should be used when dealing with peripherals for mobile devices."
• Motivation to Combine: The explicit problem stated in US7664707's background, concerning unauthorized data transfer via peripheral connections due to a lack of approval, directly provides the motivation to combine. A PHOSITA, aware of systems like US20040249994A1 that manage peripheral services and keenly aware of the described security vulnerability, would find it obvious to implement a user approval step directly on the mobile device. This step would be triggered when a peripheral connects, especially if the peripheral itself cannot handle secure user input, to prevent the "Trojan horse" attack scenario. The motivation here is driven by the clear and present security problem and the general understanding that user approval is essential for sensitive data access.

Application to Claims 1 and 2:

• Given the security concerns, implementing an approval process on the mobile device, as claimed, to protect against unauthorized peripheral access (especially from peripherals that cannot handle authentication themselves) would be an obvious solution to a known problem.

It is important to note that secondary considerations, such as commercial success, long-felt but unsolved needs, and failure of others, can be used to weigh against an obviousness finding. However, without such evidence, the combinations described above present a strong case for obviousness.
