Wang has filed suit against Netscape and America Online (AOL), alleging patent infringement. The most prominent feature of the Netscape browser potentially affected by the action is the bookmark facility for recording Web addresses.
Netscape claims the patent is invalid as the technology was already in existence before Wang claimed to invent it.
The lawsuit had escaped public attention since it was filed last October, but came to light last week when Netscape posted an appeal to developers, via its Web site, for evidence to back up its counterclaim.
The patent apparently also covers two methods of saving Web pages, which are also used in the America Online service. Neither Wang nor AOL would comment.
