I know I'm new here, so maybe what I found is not news. I'm posting this based on some questions posted here about when other radar detector companies might be able to legally sell their products with the same technology used in the V1 for showing radar direction and bogey counter. I would think if other radar detector companies could find a way of using this technology in their own radar detectors that they would of done so, if they could. The only logical reason is that Mike V. is smart enough to get patents on everything he can. Thus I can only assume there is at least one very important patent that stops others from copying the technology.
I did many searches, and found many patents on the V1, but this link seems to show the most important patent info: Motor vehicle police radar detector for detecting multiple radar sources - US Patent 5300932 Full Text - It covers a lot of stuff! And unless the patent has been extended past the date listed, this source shows the V1 arrow patent might expire in July 20, 2013 ("Estimated Patent Expiration Date").
UPDATE: Another great link with patent diagrams:
I have no way of knowing if this really means that in 2013 we will be flooded with other brands of radar detectors that display arrows and bogey counters. But it does give us a clue that the time may soon come that V1 may lose their big advantage. If anyone has more detailed information about this issue please post it here. I understand that patents can be improved and given a latter expiration date (drug companies often do this) and other rumors have circulated about what year V1 may lose their big advantage.
I welcome all comments.
