Tianma filed an Inter Partes Review (IPR) petition challenging the '394 patent. The USPTO Director denied institution of the review, not on the merits, but because Tianma's standing was questioned due to its relationship with a state-owned Chinese enterprise, concluding it was not an eligible "person" to file an IPR.
