The patents are currently assigned[i] to MES (source: MaxVal’s Assignment Database). MES alleged that defendants are manufacturing and commercializing HTC devices including HTC Inspire, HTC Status and HTC Vivid that are configurable to communicate data received from a first communication network to a second communication network as claimed in the above said patents.
The dispute has reached an end with MES filing motion to dismiss all the claims. Upon MES’s request, the Court ordered all the claims and counterclaims be dismissed without prejudice, thereby concluding the case. However, another case filed by MES against Motorola Mobility asserting the same patents is still pending.
