No, there is no infringment. Do you honestly think tunze had the origional design? No, they modified a powerhead themselves, and have tried to stop other companies from using something similar.
Vortech on the other hand, there is a clear new design development.

If Tunze has sent out a letter, they feel there's an infringement. I couldn't find anything other then talk about the letter, and I really should be working... but at a quick glance it does look like just a cease and desist letter right now. Sometimes that's the prelude to legal action, sometimes it ends with the letter.

Regardless, to me it looks like they've ripped off Tunze's innovation and design; as far as I know, it is Tunze's design. Show me where someone had a powerhead designed like that prior to Tunze and I'll happily eat my words.

What about WP-40 VS MP-40, I wonder if Ecotech is cooking something up?

Big brands always send out letters whenever they sense any form of unavoidable competition ;)

There's no "proof" that jebao stole WP-40 from MP-40's naming style (although it' s obvious). A mere twist of naming should never be considered as "steeling". The vocabulary is limited but the imagination is not and that's where "coincidences" occur.

Maybe, just curious to see if they are cooking up something.

I don't think they will do anything. Ecotech's market is much bigger than just their powerhead. Jebao has not put any sort of mark on their product in terms of anything. And I think ecotech have already responded to it to some extend, by reducing their price a bit. A much better move than tunzi issuing a letter :razz:

I am buying a product sold legally by legit and reputable stores. Get your facts right. Not stolen equipment.

Ok maybe Old timer is the wrong choice. Brand Junkie? Im just sick if reading numerous forums (not just canreef) where people who have been in the hobby for a long time, provide information to newbies such as "You should only use Radion LED's because thats what I use and if you cant use those then nothing else will do"

Or even people reading other threads saying this "letter" is now legal action when its all just rumors floating around forums which have been twisted through the power of the internet into this big problem which its really not. But again because these people wont buy a cheaper product because they have to have the brand name. Then they end up projecting there own feelings onto it and twist it even further for the next guy to read even more false information.

Again just my $0.02
