Problem with Dual Sim Mobile Phones in India
Fron 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.
This Notice is active for all the major manufacturers like Samsung, LG, MIRC Electronics, Spice Mobile & Fly Mobile , out of which Fly is going to be the biggest sufferer as they have launched many handsets with Dual-Sim capability and since in many international countries you cannot run your country based SIM everywhere so there is always a need for alternative number and these mobile phones can be very helpful. Seems like Ramkumar can become a rich guy if you calculate the Royalty fees he may earn on every handset.
Well nice article but is this patent only valid in india or all over the world if it then tell me i will take patent to three sim and four sim mobile before some one takes patent for it

@Balaji, balaji, see the matter here is, that this guy S.Ramkumar can get the royalty only from the sales of dual sims in India only. he cannot avail it offshore. so sales outside India is not affected. or this guy would have been filthy rich by now. the next problem is that the patent he has acquired is for phones with plurality of sim cards. So be it a dual sim mobile or quadra sim mobile, if you are using his technology then you will have to pay him for that. if you want a new patent then you have got to find a new technology fo the multi sim mobiles.
