It seems it takes 26 months in average to have the patents approved. So make your bet but it is just an average , can be more months. http://www.uspto.gov/corda/dashboards/patents/main.dashxml?CTNAVID=1004 1) PIEZOELECTRIC SENSOR FOR VISION CORRECTION Filing date Feb 13, 2014 + 26 months = April 13 2016 2) SYSTEM AND METHOD FOR CONTACT LENS WIRELESS COMMUNICATION Filing date Mar 25, 2014 + 26 months = May 25 2016 3) ELASTIC CIRCUIT Filing date Jul 8, 2014 + 26 months = September 8 2016 4) PIEZOELECTRIC ENERGY HARVESTING CONTACT LENS Filing date July 21 2014 + 26 months = Sept 21 2016 5) ELECTRONIC MEDICAL DEVICES AND METHODS Filing date Aug 05 2014 + 26 months = Oct 05 2016 6) MEDICAL DEVICE WITH PRE-DEFINED SPACE AND RELATED METHODS Filing date 23.09.2014 + 26 months = November 23 2016 Potentially we can have the results in 2016 for all patents applications. Be prepared.
