Dear Mr Murthy, I feel really proud about the way Infy has worked to sustain itself on top in the world market. As a professional in the same field, I also feel that Infosys should strongly focus on core technologies by coming up with patented products than just being a solution/services vendor. Thats the only way we can compete with the top players in the US and other parts of the world. I am sure that infy definitely has what it takes to invest in world class R&D in some of the core computer science technologies. I wish that you give a serious thought on this matter as Infy is now 25 yrs, pretty stable and can afford to get into core product business.
