I would consult an attorney. If I remember correctly, the actual date that your product has been known publicly (the day that you do business basically) by others, is an important factor to patents as well. If basically you can prove that your invention was out their before theirs even if they file a patent for it, and your idea was publicly known and used, I remember my attorney saying something that you can argue your case. I'd also place my money on empty threat- but you should seriously look into filing your own patent. I'd also email the guy to ask him what his online service is for some more background information.
