    Patent policies issued by standard-setting organizations help resolve the tension between enforcing patent rights and adopting open standards. In this article we examine the application of these policies to patent licensing and enforcement situations. An industry standard consists of a specified set of technologies adopted by an industry group in order to effect compatibility among products. The t... View full abstract»

  • E-commerce patents and shifting balances in patent law

    Publication Year: 2000, Page(s):106 - 110
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (84 KB)

    The rules with respect to the patentability of software and business method inventions have loosened over the last decade to allow a broader range of patentability. Many patents issuing today are in the e-commerce area, and there is often a close relationship between what is being patented and generation of wealth. Critics of the surge of e-commerce patents argue these patents may stifle developme... View full abstract»

    The current processes by which telecommunications standards are adopted are flawed. Certain companies are able to exploit these flaws to extract hundreds of millions of dollars in patent royalties from the telecommunications industry. In particular, companies can: (1) word their patent statements to appear to comply with the bylaws of an organization while not actually doing so; (2) interpret thei... View full abstract»

  • Applying QoS control through integration of IP and ATM

    Publication Year: 2000, Page(s):130 - 136
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (100 KB)

    The article describes the application of the integrated services concept where IP is using ATM as the transport layer for providing QoS control. Integrated services technologies based on IPv6 have been developed and implemented in a pan-European field trial where students are evaluating distance learning applications with QoS control. An overview of the architecture is given, followed by a descrip... View full abstract»

  • Patenting propagated data signals: what hath God wrought?

    Publication Year: 2000, Page(s):98 - 101
    Cited by:  Patents (4)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (72 KB)

    The US Patent Office is now issuing patents on propagated data signals that embody computer programs. Result: patent infringement can now occur in a mouse click. While patents have always been available for new and useful processes, machines, manufactures, and compositions of matter, the extension of patent law to computer data signals is new. After losing a series of battles in the courts, the Pa... View full abstract»

    Cited by:  Papers (8)  |  Patents (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (112 KB)

    Dynamic random access memory has been a viable semiconductor storage medium for more than three decades. Surprisingly, it has only been in the past three years that attempts to combine DRAM with meaningful amounts of Boolean logic, on the same substrate, have occurred. Although much fanfare has accompanied this technological breakthrough, commonly referred to as embedded DRAM, few system designers... View full abstract»
