With the landmark judgement against Research in Motion (RIM), a Canadian Company and the providers of the Blackberry PDA, for patent infringement in 2006 and an award of US$612.5 Million in favour of NTP Inc, a Virginia based company, it seems safe to say that the technology of push email was pioneered by NTP and not RIM as widely believed. Even as at the time of filing in this report, there is an existing suit filed against Apple, Google, HTC, LG, Microsoft and Motorola for infringement of wireless email patents.
Not withstanding, the initial setback, it is a fact that RIM has been able to create a niche for itself in the wireless email sector, so much that its Blackberry product has become synonymous with Push email. They hold the ace and all other push email providers we will discuss in this write-up only try to attain the standards set by this company.
There are many solutions available and each uses a slightly different approach. However, most mobile solutions do not use a true push-model but employ a pull-model whereby the clients pull emails from the server at set intervals instead of having the mails pushed to the device from the server.
