I have no idea about kvant going after people from what I read it should only be arctos?
If they are though they are indeed in the wrong.
Kvant's modules are compact yes but the methods used to combine and compose the modules are basic techniques we all use.. you can't claim something like that.. they put work in production but didn't have to invest in research in coming up with the product because the techiques were already there. Defending the creativity and combating people who do not have put money into research that needs to be covered with sales that's where a patent is majorily for. I'm all for defending creative minds but it's within reason.
At max lightspace or whatever cloned the enclosure look.. but lets be honest a heatsink shaped anodized module block isn't really some "New technology" "Wow this is a reason to go after people" No it's seeking ways to be greedy and get money and combat competition the childish way. If they are doing it for that then they seriously need to get their act right and not act like a bully or some form of patent troll.
I do want to see any proof of kvant going after this though and not just arctos and not just assumptions... Kvant? Input please???
