I totally agree I felt the same way. There is no real argument here. If a company thinks they have something novel, they should protect their intellectual property. If they don't, it is their own fault. If it is on the market and it wasn't protected -- then everybody under the sun has the right to manufacture something that is functionally "similar". The only caveat to this is what lawyers refer to as "Trade Dress". The "other" product can fill the same niche -- but it can't confuse the consumer to the point at which they thought it came from the original company. So in many cases, the knock off lights are just fine. But, I agree the one that looks like an Ecotech -- very well may have a "trade dress" issue. In reality, all they have to do is change the labeling to be clear. That is why every milk jug looks the same but has different labeling.
