Patents do not mean anything anymore. Chinese companies will steal and copy them (not all, but most) with no recourse. This has taken away innovation from the pump and other equipment market and I expect it to with lights as well. If you really love Kessil, you need to hope that people do not buy the alternative for less money even though it is inferior and just keep a backup on the shelf for a rainy day (ala Jeabo vs Tunze).
If this disgusts you that Kessil could lose market share and not be around to make the next generation of good lights, then it should... but then also apply this same logic and reasoning to other equipment.
The people who do not care (mostly just like that it is cheap) will point out the slightest difference and say that there is not copyright issue - everybody is a copyright expert... only unless you have given testimony in Texas Court (where most IP Infringement cases go), then you have absolutely no idea what you are talking about. The ones who get that this is one of the real serious issues facing the US and EU will stay way completely.
It will not be long until Kessil, EcoTech, Pacific Sun, etc. are all overrun with 1/3 price blatant knockoffs. Ask EcoTech how much Chinese copyright/IP theft has hurt their pump business.
