QUORUM FILES DECLARATORY JUDGMENT ACTION AGAINST APPLE COMPUTER; SUIT SEEKS RELIEF FROM ALLEGATIONS OF COPYRIGHT, PATENT INFRINGEMENT

 QUORUM FILES DECLARATORY JUDGMENT ACTION AGAINST APPLE COMPUTER; SUIT SEEKS RELIEF FROM ALLEGATIONS OF COPYRIGHT, PATENT INFRINGEMENT
 MENLO PARK, Calif., May 12 /PRNewswire/ -- Quorum Software Systems Inc. today announced it has brought legal action against Apple Computer Inc. (Cupertino, Calif.) to counter unsupported allegations of patent and copyright infringement. Quorum's lawsuit stems from recent letters in which Apple accused Quorum of infringing its intellectual property rights, and revoked Quorum's privileges as an Apple Certified Developer.
 Additionally, the complaint seeks redress for Apple's accusation that Quorum, in helping independent software developers (ISVs) migrate their Macintosh-compatible applications to other platforms, induced those ISVs to violate licensing and confidentiality agreements with Apple. Apple's assertion implies that developers have knowingly or unknowingly included Apple proprietary information in their independent source code. Quorum believes Apple cannot assert any ownership of application source code created by independent software developers.
 The complaint centers on the allegation that Quorum Latitude, a cross-platform compatibility tool that enables Macintosh-compatible applications to run on other computer platforms, violates Apple patents on "pull-down menus" and "Color QuickDraw" and Apple's copyrights. Latitude relies solely on the use of Motif or Open Look for pull-down menus and uses Adobe Display PostScript or SunSoft NeWS for screen rendering, and therefore could not infringe on Apple's patents or copyrights.
 Quorum asks the United States District Court for the Northern District of California to rule that Quorum has not infringed any copyrights or patents of Apple and to prohibit Apple from making further assertions that Latitude violates any Apple intellectual property rights.
 "From the very beginning of our technology development, we have carefully avoided any perceived or actual infringement of Apple's intellectual property rights," said Sheldon Breiner, president and co- founder of Quorum. "For Apple to accuse us of impropriety is to discredit the technical innovations we have achieved in our Quorum Compatibility Engine and Latitude product."
 "Like any other independent developer, we read publicly available information such as Inside Macintosh and then wrote some innovative software," said R. Martin Chavez, co-founder and chief technical officer. "The Compatibility Engine simply liberates Macintosh- compatible applications to run on other platforms without touching any of Apple's Macintosh technology."
 Quorum Latitude is based on a core technology called Quorum Compatibility Engine. When an original Macintosh-compatible application makes a call to any systems facility, the Compatibility Engine responds by rerouting the request to a similar service resident on computers using the UNIX operating system. For screen display, the Compatibility Engine redirects Macintosh-proprietary QuickDraw calls directly into Display PostScript or NeWS. The PostScript language is a hardware-independent imaging language that supports any range of display, resolution and output devices.
 Quorum Software Systems was founded in 1989 to develop and market cross-platform compatibility tools for a variety of computer environments. Quorum licenses its technologies to system vendors, software developers and end users.
