^ The problem, for me, is that I'm no patent attorney.
In as far as I understand things, as a total layman, as long as two ideas have sufficient differences, a separate patent can be made.
Perhaps the different products are just sufficiently different, as to allow for unique patents?
Or, alternatively, it's also possible that what's in the rumor mill is true - that back in the day, Lidatek was in the same position as Blinder/Escort is in, now: that for whatever reason (most likely one of cost/effort), they simply chose not to pursue enforcement of the patent(s), knowing that pursuing such would likely mean themselves more economic hardship than the results would be worth.
Independent hobbyists like me, on the outside, will, I suspect, never know the extent of background handshakes that happen in this industry.
^ That was understood from day one. No worries.
^ I think you've been around enough that you wouldn't need to hide behind such multiple identities.
that has been my point from day one, none of us are patent attorneys, we are not the court system, it is not up to us to judge any company. What we think is just an opinion. As a hard core enthusiast, I just want to use the best and most reliable product. If it is Lidetek then fine. If it is LPP fine. If it is AL fine. If it is Blinder fine. If it is Belscort fine. If it is LI fine. Just leave us out of the politics.

It has nothing to do with "ideas". The U.S. Patent Office does not patent ideas. You need more than just an idea, you need proof that it would work in the real world. That is why they make you do what is called "reducing it to practice".
Not to get off subject but does anyone have a cliff notes version of why Lidatek went out of business? Is there any reason to believe that Lidatek would not start up operations again?
