The application, database and Windows management specialist expects revenue to show a 27% increase to a range of $90m to $91m, compared with its prediction in April of $87m to $89m. Pro forma earnings are also expected to be at the top end of earlier guidance of $0.07 to $0.09, though they could be hit by legal costs from its battle with CA.

Quest says it has now received an order from the US District Court for the Northern District of Illinois indicating it will grant CA’s motion for a preliminary injunction to stop it selling its Quest Central for DB2.

Irvine, California-based Quest said that compliance with a preliminary injunction pending trial will not have a material effect on future operations, because the products at issue represent 3% to 4% of total revenue and have not been profitable.

CA launched a lawsuit against Quest in 2002, accusing it and four named employees of copyright infringement and trade secret misappropriation. It claimed that the four employees, who had previously worked for Platinum Technologies Inc, used the source code from Platinum products to create the Quest Central database management system after they joined Quest in 1999. CA acquired Platinum earlier that year for $3.5bn.

According to court filings, CA said that in developing Quest Central, the four developers used the source code for what is now CA’s Enterprise Database Administration product. CA asked the court to order the destruction of Quest’s products that infringe its property and also demanded profits and damages.
