Research In Motion has produced a workaround for systems covered by the patents it is disputing in the US.
The product, Blackberry Multi-Mode, will be pre-loaded onto all new Blackberry handsets and is being incorporated into Blackberry Enterprise Server software.
Existing users can install the workaround but RIM said it was continuing to fight its patent dispute with NTP, which could lead to the USBlackberry network being shut down.
Meanwhile, Microsoft is improving intellectual property dispute protection on its rival mobile platform.
Microsoft has extended its intellectual property protection programme for companies that develop hardware and software powered by Microsoft Windows Embedded and Windows Mobile software. The extended cover means Microsoft will defend manufacturers and distributors against intellectual property claims in every country in which it distributes or markets its Windows Mobile and Windows Embedded products.
