Exmark's ECS patent. When does it expire?

Anyone know. When it does it's main advantage in WB's will disappear. Already Scag has a very similar system on it's new WB.

Well then go buy something else. There is more to Exmark than ECS to most people who own tjem.

That Scag is nowhere near a Turf Tracer X series. They don't offer a 60" either. Wouldn't even consider purchasing one until they made something as heavy duty as a X series 60". Their current walk behind just would not please me. I also like the height adjustment on the turf tracer even though a lot of people hate it. It allows me to use washers to narrow down the height adjustment to 1/8th of an inch.

If Scag made a walk behind like the X series 60" with their advantage deck and the good ECS style controls, I would take a serious look. It is beyond me why they don't make a machine like this. Exmark owns the walk behind segment by an incredible margin.

I have an eXmark Viking with ECS and I love it.
Have not owned a Scag walk behind, but I don't see a reason to change from the Viking any time soon. I love the ECS controls and the cut from the Tri-Vantage is fantastic

Agree Exmark's WB's are top notch. My TTHP 36" is a workhorse. ECS never wears my hands out.

If only their Z's were half as good.

I have their Z with around 1000 hours on it, and a couple minor repairs. I have had as much downtime on that, as I've had on the 30" I bought this year. I expected some problems with the 30, because it was a new design. I don't have the Turf Tracer. I went the cheaper route with the Viking and agree about the Ecs. I think I am selling the pistol grip Metro because the ECS spoiled me. I am tired of pushing it up hills with wet belts.

More or less a patent term on a design is 20 years.

This isn't always useful because you can design say a battery, but then someone designs a solar energy cell that makes the battery obsolete and even tho you have the patent your aren't making any money because no one is buying it anymore.

(kinda like Beta max/VHS)

I can't recall when ECS first came out exactly, but I doubt the above post has any validity.
Because the 20 years starts from the point when the patent was first filed.
So patent pending status wouldn't extend the patent term.

But for example, audi quattro.
Most AWD systems are based on older versions of audi quattro, the current generation is under patent.
You can improve upon something and patent that.

So once your patent on Generation 1 ECS expires, you come out wit Gen2, and everyone is stuck copying Gen1 (one of the reasons why Audi is so successful)

Although, technically, ECS is so basic there might not be much exmark could do to come out with a gen2 that was different enough to patent.

Scags SWZT controls are already better than ECS.
