You may not know this but Ryan Seacrest is the founder of an iPhone accessory company called Typo. Typo designed and sells an add-on iPhone physical keyboard which Blackberry claims is a copy of its own proprietary design.
Here is a picture of the Typo keyboard installed on an iPhone 5s
A report by CIO magazine says Blackberry has submitted a request to the US District Court in Northern California to block Typo from "making, using, offering to sell, or selling within the United States, or importing into the United States, the Typo Keyboard.”
Blackberry has said it will "vigorously" defend its unique keyboards intellectual property and of course Typo has said ”BlackBerry’s claims against [us] lack merit and we intend to defend the case vigorously.”
The first shipment of Typo keyboards is already sold out and new orders are expected to be delivered in March (each kit costs $99). If you own an iPhone 5s, be aware that you lose the fingerprint capabilities when this case is installed. You can order one directly from Typo keyboard if interested (link).
