- Full Citation: US7376773B2 - Multi-standard protocol storage devices and methods of operating the same.
- Priority Date: 2003-07-04
- Publication Date: 2008-05-20
- Brief Description: This patent describes multi-standard protocol storage devices and methods for operating them, indicating a device capable of communicating using various protocols.
- Potential Anticipated Claims: This reference is highly relevant to Claim 1 due to its focus on multi-standard protocol storage devices. It could anticipate the presence of both USB and I/O ports with their respective controllers, and the ability of a memory card to interface using different protocols as described in Claims 9 and 16.
US20050063540A1
- Full Citation: US20050063540A1 - Digital media cartridge system and method.
- Priority Date: 2003-07-23
- Publication Date: 2005-03-24
- Brief Description: This patent application describes a digital media cartridge system and method, which suggests a portable storage device for media content.
- Potential Anticipated Claims: Similar to US20020186842A1 and US20040083378A1, this could broadly anticipate the memory card's function as a portable media storage device, touching upon the scope of Claims 1, 9, and 16, especially concerning the handling of data (audio/video).
US7287703B2
- Full Citation: US7287703B2 - Removable memory cards including USB and other controllers, connectors, and methods of operating same.
- Priority Date: 2003-07-23
- Publication Date: 2007-10-30
- Brief Description: This patent describes removable memory cards that include USB and other controllers, connectors, and associated methods of operation.
- Potential Anticipated Claims: This is highly relevant to Claim 1, as it explicitly mentions removable memory cards with both USB and "other" (I/O) controllers and connectors. It directly addresses the core hardware components of Claim 1, and the methods of operation would cover the data handling aspects of Claims 9 and 16.
US20060084287A1
- Full Citation: US20060084287A1 - Memory card with two standard sets of contacts and a contact covering mechanism.
- Priority Date: 2004-04-16
- Publication Date: 2006-04-20
- Brief Description: This patent application describes a memory card featuring two standard sets of contacts and a mechanism for covering these contacts.
- Potential Anticipated Claims: This reference directly anticipates aspects of Claim 1 related to a memory card having two distinct sets of pins (e.g., USB and I/O) and how they are exposed or protected. The "same card-insertion direction" feature of Claim 1 might distinguish it, but the fundamental idea of dual-interface contacts is present.
US7433994B2
- Full Citation: US7433994B2 - On-device data compression to increase speed and capacity of flash memory-based mass storage devices.
- Priority Date: 2004-12-07
- Publication Date: 2008-10-07
- Brief Description: This patent describes on-device data compression to enhance the speed and capacity of flash memory-based mass storage devices.
- Potential Anticipated Claims: This reference is highly relevant to Claim 3, which claims decompression circuitry, and to Claim 9 and Claim 18, which involve decompressing data on the memory card. The focus on "on-device data compression" directly relates to the concept of the memory card itself performing compression/decompression.
US20060177064A1
- Full Citation: US20060177064A1 - Secure memory card with life cycle phases.
- Priority Date: 2005-02-07
- Publication Date: 2006-08-10
- Brief Description: This patent application describes a secure memory card that incorporates life cycle phases, likely implying features for managing encrypted or protected data.
- Potential Anticipated Claims: This reference could potentially anticipate Claim 2 (decryption circuitry) and Claim 10 (decrypting encrypted data), as "secure memory card" and "life cycle phases" often involve encryption and decryption mechanisms to protect data access and usage.
US7491076B2
- Full Citation: US7491076B2 - Rotatable memory card with improved locking mechanism.
- Priority Date: 2006-04-18
- Publication Date: 2009-02-17
- Brief Description: This patent describes a rotatable memory card with an improved locking mechanism.
- Potential Anticipated Claims: This patent seems to focus on the mechanical aspects of a memory card's physical form factor and locking mechanism. It does not appear to directly anticipate the electrical or functional claims of US8327051, particularly Claim 1, 9, or 16, beyond the general concept of a "memory card."
US20080071940A1
- Full Citation: US20080071940A1 - Device of identifying host protocol and smart card including the same.
- Priority Date: 2006-07-21
- Publication Date: 2008-03-20
- Brief Description: This patent application describes a device for identifying a host protocol, and a smart card incorporating such a device. This implies a memory card capable of recognizing and adapting to different host interfaces.
- Potential Anticipated Claims: This reference is highly relevant to the concept of a memory card interfacing with different host devices using different protocols, as described in Claim 1 and implied in the methods of Claims 9 and 16. The "identifying host protocol" directly relates to the card's ability to determine which port to use for communication.
