Successful defense against a lawsuit concerning patent infringement (court of first instance)

On October 27, 2011, the Osaka District court rejected a claim by the plaintiff concerning unjust enrichment in favor of our client.
In this case, the plaintiff, which is a manufacturer of communication devices, electrical equipment, etc., claimed that our client's acts of manufacturing and selling certain products infringed their patent regarding "the transmitter and receiver switching device of networking equipment," however, the court sustained our contentions and rejected all of the plaintiff's claims.
Hiroshi Suga, Mitsuru Shishido and Yumi Ueda represented the defendant in the case, which our client won.
