I've been a REFR shareholder since 2001 and am currently increasing my position. I see from your posts that you're a new shareholder, and also that you expect all 40 of RFI's licensees to become actively involved in the SPD industry in the near future.
I suggest you stop relying on this board as a place to find accurate information on RFI's prospects, because everyone posting here, myself included, has something at stake that influences what they say. As to the licensees' participation, this is from the latest Annual Report released this past March:
"Due to their bankruptcy filings or other termination of their general business activities or for other reasons, the Company does not believe that Polaroid Corporation, Kerros Limited, ThermoView Industries, BRG Group, SPD Technologies, SPD Systems, and Film Technologies International are pursuing business activities with respect to SPD technology. Also the Company and licensee N.V. Bekaert, S.A mutually agreed to terminate their license agreement during 2008 for reasons unrelated to SPD technology. Some of the Company’s other licensees are currently inactive with respect to SPD technology, but may hereafter become active again."
I suggest you study the company's filings or contact the company and licensees directly with your questions before investing more of your net worth. Good luck!
