Swirlate IP has filed a lawsuit in the District of Delaware against AudioCodes Inc., an advanced voice networking software company, for patent infringement alleging that the defendant infringed its automatic repeat ReQuest Transmission patent.
The plaintiff alleges that the defendant infringed its patents-in-suit with United States Patent No. 7,154,961 (the ’961 patent) and 7,567,622 (the ’622 patent) covering Constellation Rearrangement for ARQ Transmit Diversity Schemes.
The plaintiff reportedly said that the patent covers a method for transmitting data using transmit diversity schemes in which data packets are transmitted using a first and second transmission based on a repeat request and the bit-to-symbol mapping is performed differently for different transmitted diversity branches.
The plaintiff reportedly said that the defendant infringed the ’961 patent through its Instrumentality which uses an ARQ retransmission method in a wireless communication system in which data packets are transmitted from a transmitter to a receiver using a first transmission and at least a second transmission based on a repeat request.
The plaintiff reportedly accused the defendant of direct, indirect, contributory, and induced infringement.
The plaintiff is seeking a declaratory judgment in its favor, an order enjoining the defendant from further
infringement, an award for damages, pre-and post-judgment interest and costs, and other relief.
The case is ongoing.
