World’s second largest information technology company apple is setting targets to double its iphone sales with more focus on ecommerce. This is one of the challenges that the company is facing in Smartphone markets. An Indian company called iVoice Enterprises is intensifying its battle against the Cupertino giant over the claim to the ‘iPhone’ brand. It had plans to make affordable smartphones under the ‘iFon’ brandname. “Apple’s original opposition to ‘iFon’ trademark caused insurmountable challenges and irrevocable losses in ramping our business during 2008/2009. Given the rejuvenated Indian economy, we’re on our way to revamp our business model and one key metric to regain investor confidence is to secure unencumbered rights to our ‘iFon’ intellectual property in India.Ivoice MD said.
