From the past year there has been a huge rise in the sale of the Dual SIM Mobile phones in India which is randing in around 1,00,000 Dual-sim handsets sold every month but now there is a stop on this and you cannot even guess the reason for this. Somasundaram Ramkumar who is a Madurai resident holds a patent for ‘Phones with Plurality of SIM Cards’ which means that whenever someone sells a handset with Dual-SIM facility, they need to pay RamKumar a royalty of Rs35 and this Patent is valid for 5 long years. This Patent can help him become quick rich because the popularity of these handsets is increasing and all the importers and manufacturers have to pay Rs35 before they sell the handset to the consumers.
