RIM announced that net profit was $329 million (£208 million) for the three months to 27 August, down from $797 million in the same period a year earlier, wireless communication device users may be among those interested to learn.
Some 10.6 million BlackBerry smartphones and around 200,000 Blackberry PlayBook tablets were shipped during the quarter - which is significantly below analysts' expectations.
The announcement saw RIM's shares fall by ten per cent in after-hours trading in New York.
In other industry news, Samsung recently filed a patent complaint against Apple in France, arguing that its US rival infringed on three mobile technology patents in the iPhone and iPad.
A Samsung spokeswoman confirmed that the French case is based on "three technology patents, and not on the design of the tablets".
