Motorola officially announced that Symbol Technologies and Wireless Valley Communications, two of its subsidiary companies, have filed on 27th of August a patent infringement lawsuit against the Californian company Aruba Networks. The Lawsuit was filed in the United States District Court for the District of Delaware and it's about Aruba Networks' infringements of WLAN communication technologies patents.

Motorola, Symbol Technologies and Wireless Valley Communications are leaders in network communication technologies and have several patents directly related to wireless local area network technologies. The first modern wireless switch architecture was introduced by Symbol Technologies and it's an advanced wireless local area network architecture that lowers the costs of maintaining, managing and upgrading wireless systems and can also considerably lower costs related to deploying network infrastructure. Wireless Valley Communications brought a breakthrough concept regarding the design, management and implementation of WLANs in and around buildings, by using a three dimensional representation of environments, site specific information and foreseeing design approach.

Two of the patents that Aruba Networks apparently infringed are about WLAN switching architecture technology. Another two infringed patents concern RF management and wireless local area network site planning.

Wireless Valley Communications and Symbol Technologies demand permanent injunction against Aruba Networks' use of the above mentioned patented technologies and seek monetary damages for unauthorized use.

Aruba Networks Inc. is a company based in Sunnyvale, California. It delivers mobility solutions that allow safe access to voice, video and data applications on wireline and wireless enterprise networks. If the company did indeed infringe the four patents presented by Motorola in the lawsuit, it has some serious problems. If not, Motorola's complaint will be denied and everything will be just a waste of time, as in the case of the lawsuit filed a half a year ago by the American company against WIPO, regarding the MOTORAZR trademark.
