There are several this year (2015). I collected at Autumn Canton Fair one Expandable Hose catalog which shows some new types including those seemingly having different structure of the patented X-Hose.
1) Normal or Conventional expandable hose (X-Hose patented type)
2) Film expandable hose - seems using three tubes not two tubes like X-Hose
3) Durable expandable hose - seems using three tubes like the above Film expandable hose.
4) Snake expandable hose - looks like a suction hose - quite different structure and mechanism from X-Hose. I once considered this and check possibility with some suppliers in China but gave it up as they were concerned more about the negative pressure not extension.
5) Elastic expandable hose - looks like <Uber-Hose> and <G-Hose (Taiwan)> - distinctively different structure and mechanism from X-Hose.
6) Intermittent expandable hose - I do not understand the feature of this hose.
-------
Hoses 4) and 5) have quite different structures from X-Hose and may not infringe the X-hose patents.
