BlackBerry won a key ruling late Friday, blocking the sale of the Typo, a Ryan Seacrest-backed keyboard case for the iPhone. The Canadian phone maker sued in January seeking to halt the sale of the device, which it says infringes on its patents. A federal judge late Friday ruled that BlackBerry was likely to prevail and issued a preliminary injunction halting sales of the case. “BlackBerry has established a likelihood of proving that Typo infringes the patents at issue and Typo has not presented a substantial question of the validity of those patents,” Judge William Orrick wrote in the ruling. “In addition, the balance of equities and the public interest weigh in favor of granting a preliminary injunction.” Typo said in a statement that it was disappointed and plans to appeal, adding that it “will continue to make and sell innovative products that busy people can’t live without.”
