Gartenberg said large enterprises, which make up the most valuable customer base for RIM, would likely start looking at competing devices from the likes of Microsoft, Good Technology, Palm and Visto if the legal proceedings drag on.

However, in a statement, RIM insisted demand for its products remained high. "RIM's business generated higher than expected revenue during the summer months resulting in a record quarter. The top-line growth together with prudent expense management also allowed us to significantly exceed our profitability targets," said RIM chief financial officer Dennis Kavelman.

In a statement, Kavelman said global demand for BlackBerry accelerated in both enterprise and consumer market segments. He said RIM fulfilled orders to its carrier partners during the most recent quarter to satisfy new subscriber growth, hardware upgrade sales and retail channel expansion requirements.

Separately, RIM announced the availability of its S/MIME Support Package v1.5 for BlackBerry. The company said the software add-on would provide S/MIME (define) authentication support for Java-based BlackBerry devices.

S/MIME, or Multipurpose Internet Mail Extensions, is a standards-based protocol for formatting non-ASCII messages so that they can be sent over the Internet. It uses public key cryptology to provide writer-to-reader security features such as authentication and confidentiality message integrity.
