Delrina was a Canaian software company based in Toronto, that existed between 1988 and 1995, prior to being bought by the American software firm Symantec. Delrina started out by producing a set of electronic form products known as PerForm and later, FormFlow. However, the company was best known for its WinFax software package of the early- to mid-1990s, which enabled computers equipped with fax-modems to communicate faxes to stand-alone fax machines or other similarly-equipped computers. Delrina also produced a set of popular screensavers, including one that resulted in the well-publicized "flying toasters" lawsuit for copyright and trademark infringement (Berkeley Systems Inc. v. Delrina); the case set a precedent in American law that satiric commercial software products were not subject to the same First Amendment exemptions as parodic cartoons or literature.
