U.S. District Judge William Orrick in San Francisco said that the Canadian mobile phone maker had established a "likelihood" of proving that Typo infringed its patents, while mentioning that Typo had not sufficiently challenged the patents in question.

The preliminary injunction prohibits Typo from the sale of its keyboard, which is a part of the relief sought by Blackberry.
"BlackBerry is pleased that its motion for a preliminary injunction against Typo Products LLC was granted. This ruling will help prevent further injury to BlackBerry from Typo's blatant theft of our patented keyboard technology," a spokeswoman for BlackBerry said in an email.
Typo said it was disappointed and plans to appeal the decision.
"Typo will continue to make and sell innovative products that busy people can't live without," the company said in a statement.
In January, BlackBerry had filed a lawsuit against a company co-founded by "American Idol" host Seacrest that offers a physical keyboard that can be attached to some of Apple Inc's touch screen iPhone 5 models.

Typo had later said that it believed that the lawsuit filed by Blackberry lacked merit.
The BlackBerry complaint is case no. 14-cv-00023-WHO in the United States District Court for the Northern District of California.
