My reason for investing here has and will continue to be the patented technology. I am conviced Smiths and Morpho have no answer, and have vacated the ETD marketplace. Neither are U.S. based, one was recentely involved with a federal lawsuit with our Government. IMSC is a pure play, those other two have many other iron's in the fire. Based on recent PR's from them it seems they are re directing efforts in other areas of technology/servicing of legacy equip etc. Typical progressive movement by TSA, but when sorted out I think it will be worth the wait, which has been a very long one. Rest of the year will be interesting,we should have a pretty good idea where we stand by then.
