RE:One little observation from the ALE/Gatekeeper website infonot sure I agree with your TM analysis. Trade marks are for brand names only so in GSI's case ALE is a trade mark. The system ALE represents is not covered by any protection unless it was a patented item. I doubt it would be patented since other companies have similar products. The protection GSI would have is for anyone else trying to use the ALE name on their product. This is the way I understand the use of trade marks.
