Protexis' Fifth and Sixth Patents Approved, Further Expanding Its E-commerce IP Portfolio

    VANCOUVER, BRITISH COLUMBIA, December 20 /CNW/ - Protexis, the leader in
digital content distribution for retailers, today announced that the U.S.
Patent and Trademark Office issued U.S. Patent No. 7,200,760 to Protexis, as
well as approved the claims of a forthcoming patent that expand the company's
patent holdings surrounding its product activation-based system of copy
protection, digital rights management, electronic licensing, and e-commerce
services for software and digital content. Four other patents covering
fundamental aspects of the Protexis platform have already been issued, with
eleven additional patents pending.

    "U.S. Patent No. 7,200,760 covers persistent encryption of software data
to control the operation of an executable. The approved claims in the
forthcoming patent cover additional unique product activation technology for
publishers of digital content to market and license their software," said Karl
Hirsch, CEO of Protexis. "Users also benefit from this technology which
affords simplified and efficient real-time digital packaging of multiple
protected items and decryption of these items."

    "Protexis is committed to building an intellectual property portfolio
around our proven expertise in online content distribution, electronic
software distribution, digital rights management, and product activation,"
added Hirsch. "The patent portfolio we have developed spans more than a
decade. Our company launched the world's first commercial product activation
based anti-piracy technology following those early patents, and now we are
building further on that IP foundation to change the face of digital content
distribution with our latest services breakthrough, RED(SM) - Retail
Electronic Distribution.

    "Receiving these new patents further validates the strength and scope of
Protexis' patent portfolio and its vision to provide the infrastructure for
efficient global distribution of digital content for publishers and their
retail partners," added Hirsch.
