RIM wins patent dispute with Motorola

RIM's BlackBerry

A London judge has ruled that BlackBerry maker Research in Motion (RIM) did not infringe Motorola patents for email gateway systems.

According to reports, the judge invalidated the patent, but also said RIM's systems had nothing to do with Motorola's tech. The two firms have been battling it out since an agreement between them ended in 2007.

A RIM spokesperson said: "Motorola has been trying to compensate for its losses in the marketplace and its inability to sell its mobile division by resorting to court actions that are designed to help negotiate unreasonable royalty rates."

"RIM has always been willing to pay a reasonable royalty rate for any required license and today's court ruling is consistent with RIM's longstanding view that Motorola has simply been acting unreasonably," the statement added.

Motorola is yet to respond to our request for comment, but has also asked American regulators to look into five other patents it says RIM has infringed.
