Message: Patents' Status/Samsung
Listed below are abstracts of the four patents on which we claimed infringement by Samsung. If my understanding is correct, the first two are still "in play" and claims related to the last two have been dismissed. Isn't '445 MOS? :(
5,491,774 (“the ‘774 Patent”) issued on February 13, 1996
“Handheld Record and Playback Device with Flash Memory.”
A record/playback device for use with a removable, interchangeable, flash memory recording medium which enables extended recording comparable with tape cassette dictating equipment. The device includes a housing, a microphone element, control circuitry and a switch mounted on the housing for selecting desired functional operations. A receiving socket is coupled to memory circuitry associated with the control circuitry and is configured for electrical coupling with a flash memory module adapted for receiving and retaining recorded digital information for storage in nonvolatile forme.
5,742,737 (“the ‘737 Patent”) issued on April 21, 1998 “Method for Recording Voice Messages on Flash Memory in a Hand Held Recorder.” A solid state digital hand held recording device having a multifunctional switch assembly. A printed circuit board including a microcontroller electrically coupled to switch terminals operates to control the processing of sound into electrical signals and store said signals on a digital recording medium. The switch assembly actuates electrical signals coupled to said microcontroller thereby activating a sequence of actions (a program) stored within read-only memory device. A plurality of programs can be activated to instantaneously begin recording a message, verify the integrity of the recording medium, and index a message being recorded for rapid recall. 5,787,445 (“the ‘445 Patent”) issued on July 28, 1998 “Operating System Including Improved File Management For Use in Devices Utilizing Flash Memory As Main Memory.” A method of memory management for a primary memory created from a non-volatile, long-term storage medium, in particular flash memory, which enables direct manipulation of data segments stored therein. The data segments of a single file are typically not stored contiguously in relation to the order in which they are stored and subsequently recalled, yet the method enables recall in the logical order in which the data segments were created. This method is particularly useful for flash memory which has the characteristic of not being able to overwrite data in memory without first erasing previously recorded data. The method comprises the minimum steps of dividing the primary memory into equal size blocks, each block being the smallest amount of data which can be read from or written to memory in a single read or write operation. A cache memory the size of at least one of the read/write blocks is then coupled to the primary memory and provides temporary storage space for data being written to and read from primary memory. 5,839,108 (“the ‘108 Patent”) issued on November 17, 1998 “Flash Memory File System In A Handheld Record And Playback Device.” A record/playback device for use with a removable, interchangeable, flash memory recording medium which enables noise dampened recording of voice data and CD quality stereo recording of music data. The device includes a port for receiving a flash memory module which can record data according to industry standard formats to enable the transfer of data to and from personal computers through swapping of flash memory media. Alternative forms of data input and output also include implementation of a barcode reader and an infra-red transceiver for the transfer of data to and from the device.
