TORONTO -- Stock in Research in Motion was up five per cent following a report that IBM is interested in some of the company's assets.

According to the Bloomberg news agency, the U.S. technology giant made an informal approach about the possibility of acquiring RIM's enterprise division, which operates a network of secure servers used to support its BlackBerry devices.

However, the report indicated nothing had come of the approach and that no talks between the two companies were underway.

When asked about the story, RIM said it does not comment on rumours and speculation.

Meanwhile, the Waterloo, Ont.,-based company received good news on the legal front Wednesday when a U.S. judge overturned a $147.2-million patent infringement verdict in favour of Mformation Technoligies Inc. The case involved software for managing mobile devices.

On the Toronto Stock Exchange, RIM shares were up 38 cents at $8.10.
