Lawnmower , ha! Very dope. Well here is the thing about patents. A US patent is simply legal protection under the American government that another entity cannot copy your exact design and use it for profit for a certain number of years (I am being vague because you gotta pay me for detailed info
) Patents do take alot of time and money to go through because we have a tremendous backlog. However you can still make and produce technology before your patent goes through you just run the risk of someone copying it , this is why you see alot of products with labels such as "patent pending) . That second patent was granted in 2014 and was more so focused in scope on a flow regulating device not an oil seperator. We do agree on alot of points about this . Catch cans definitely are not a cure all solution. I simply just don't see the harm in addition onto the OEM system to increase effectiveness . From my own testing on my own platform I deem it not effective enough . On the old VW GTI forums similar convos were had. Oil dilution , the technological advancements of VW, etc etc. And the end result was me personally ending up with tons of carbon buildup because I did nothing . As well as on this platform people said I would have to add boost , downpipes , tunes , intakes etc to get this amount of blow by. Now maybe I have more blow-by than most (I have to wait for oil results to come back) but I shouldn't with a new engine that I have taken care of . I guess the cans are more so specific to driving style and location . There are alot of variables here. My statements aren't really directed towards you. But catch cans get a bad rep. People will spend hundreds on blow off valves , intakes , turbo inlets , resonator deletes , cat back exhausts , air filters etc etc and effectively gain ZERO performance AND void there warrenty . But when it comes to a catch can that could assist in preventing the single most expensive component on your vehicle (engine) people are like holy shit 200 dollars for a catch can your doing drugs and wasting money . *Shrug. I would advise every one to do testing on there own vehicle . I'm happy with the performance of my can this far. But again this has alot to do with a multitude of variables like driving style and location . And lastly if Hyundai has had this technology for the past 5 years or so why did it not show up sooner ? Cost to manufacture ? Maybe. Implementation timeline ? Maybe . I just don't trust OEM companies to spend top dollar to eliminate this issue that's all. If they were willing to we would all have port + direct Injection vehicles like the GTIs in Europe.
