In what can be termed as another instance of mobile manufacturers being taken to the courts over patent violations, Motorola and Research in Motion (RIM) have been sued by Klausner Technologies for violating its patent.
Klausner Technologies, a company which has 25 patents pertaining to visual voicemail technology, has apparently filed the lawsuit in the U.S. District Court for the Eastern District of Texas. It is important to note that Judah Klausner, the inventor of PDA and electronic organizer, is the founder of Klausner Technologies.
The company has charged Motorola with using its patents without its permission in its Cliq phone which apparently is based on Android OS whereas RIM has been charged with patent infringement for using the technology in the 3G BlackBerry Bold 9700 phone without its permission.
Interestingly Klausner has also filled lawsuits against companies like Cox Communications, Google, LG, Apple and Verizon, seeking damages for patent infringement.
Visual Voicemail, which was first popularized with iPhone, is a technology which allows its users to view a list of voice messages in turn allowing them to choose the ones they wanted to listen to. The technology today has become available in some smartphones and many upcoming handsets are expected to carry features based on similar technology.
Klausner, unlike many other so called patent trolls, has indeed helped to invent the personal digital assistant. The patent for the latter was granted in September 1978, well before Apple was interested in getting the Newton up and running.
