BlackBerry is suing a new company in California called Typo – for infringing on its patents by offering a cellphone case that attaches to an iPhone – to create a physical keyboard.

BlackBerry’s suit is against Typo Products LLC which was founded by entrepreneur Laurence Hallier and TV host and media personality Ryan Seacrest.

The Typo Keyboard is expected to become available later this month.

In a statement, the Waterloo – based smartphone maker says “This is a blatant infringement against BlackBerry’s iconic keyboard, and we will vigorously protect our intellectual property against any company that attempts to copy our unique design.”

BlackBerry does still offer its signature physical keyboard on some of its products but has moved toward touchscreen models on its new devices.
