CD ROM, Inc. today announced the notice of allowance from the US patent and trademark office for their second patent on compression on CD-ROM and DVD discs. This patent, called the CRI-X3 patent, increased the company’s patent portfolio to five awarded patents.
Compression Technology: Notice of Allowance from the US Patent and Trademark Office
The USPTO has issued a notice of allowance on USA’s second patent application for compression on CD-ROM and DVD
Las Vegas, April 25, 2001, CD ROM, Inc. pioneered a new technology that first permitted real-time access to compressed data on optical media in 1993. An application for a patent protecting this technology was filed in 1994 resulting in patent # 5,668,970. A second patent was applied for in 1997 which continued the first set of technical developments and set up a bridge between DOS and early versions of Windows, and the newer 32-bit and higher operating systems.
CD ROM is pleased to announce that this second application will soon mature into an issued United States patent. The United States Patent and Trademark Office, after an exhaustive examination, recently awarded CD ROM with a Notice of Allowance of its patent application. The application is expected to issue as a patent in the next two to three months.
The new patent claims cover processes for accessing compressed data on optical media, including both CD-ROMs and DVD-ROMs. One of the allowed claims, for example, covers:
“.… A method for dynamically generating a file allocation table base upon files storage information on a CD-ROM for retrieving compressed files directly from the CD-ROM…”
CD ROM’s patented technology, currently being marketed under the trademark CRI-X3™, permits standard off-the-shelf or custom compression algorithms commonly used on a read-write magnetic media to be used effectively on read-only optical media. The technology offers at least two significant competitive advantages in the rapidly evolving optical industry. First, the amount of information which can be stored on the DVD increases from a standard 4.7GB of data to on average three times that amount. Second, access to the compressed data on the optical media speeds up in direct proportion to the compression ratio. A CD-ROM or DVD-ROM which has the CRI-X3™ code can be read at double or triple the normal data transfer rate. Compression rates have been achieved in excess of 62 times.
Dr. Roger Hutchison, President and CEO of CD ROM, Inc. said of the patented technology:
“The CRI-X3™ technology offers a more efficient means of first placing and then accessing information from optical media. This is accomplished by utilizing the same fundamental processes which make standard telephony able to place simultaneous digital calls on the same twisted copper wire. Our technology, when widely utilized in the computer and entertainment industry, will offer a fundamentally new and better way of storing, accessing and transmitting data from optical media to the end-user. The implications of our compression and decompression process are far reaching in the telecommunications, broadband industry, and entertainment industry.”
CD ROM, Inc. is the oldest privately-held CD-ROM and optical products company in the industry. The Company has been widely acknowledged as being an industry pioneer. The Company develops technology and provides application solutions to it’s customers. This CRI-X3™ patent award will add to the existing intellectual property portfolio owned by the Company.
