What's the owner of the durock
system's name??
I can look up the patent, see when it expires, what exactly it covers, and how many patents he has.
Edit, THINK I found them.
Crash course in patent law. These patents have what is called CLAIMS. The claims define the legal protection. The body and drawings of the patent explain the background and give support to the claims. In order for someone to infringe the patent they need to make, sell, or offer to sell (in the US) each and EVERY element of the claim. Without going down the rabbit hole of law, these are the basics. Take the patent immediately below. It lists slotted openings. If you did not have slotted opening you cannot infringe that claim. There may be other claims in the patent, but if they refer back to claim 1, and you don't infringe claim 1, then you do not infringe the patent. Now would something as simple as square openings instead of slots "get around" the patent? I would have to research it, but likely yes, it would get around the patent.

1. A combination for plumbing fixtures comprising: a substantially planar
shower tray bonding disk on a flooring substrate and surrounded by a prefabricated polymer foam
shower tray on said flooring substrate and at the circumference of said bonding disk; said disk including an interior rim that defines a drain opening and a plurality of slotted openings for permitting mortar to penetrate the disk; and said drain opening in said disk being positioned at a drain cutout in said flooring substrate.

1. A combination for plumbing fixtures comprising: a substantially planar
shower tray bonding element that defines a drain opening; said planar bonding element including a plurality of openings outside of said defined drain opening for allowing mortar to penetrate said bonding element; and a prefabricated
shower tray surrounding said planar bonding element at the perimeter of said bonding element.

1. A flanged plumbing fixture comprising a main fixture body with a planar flange projecting laterally therefrom, the flange having a rigid planar thermoplastic core layer having opposing outwardly facing planar surfaces with two planar fabric layers coextensive with the opposing planar surfaces of the thermoplastic core layer and fused respectively to the opposing planar surfaces each planar fabric layer being comprised of a plurality of textile fibers interengaged with each other in a textile structure defining interstices between the fibers, each planar fabric layer forming respective outwardly exposed faces of the fixture presenting an open three-dimensional mortar-bondable fabric structure suitable for interstitially receiving and bonding with a plumbing mortar.

1. A composite backer board for wet space construction, said board consisting essentially of: a rigid foam core of a suitable thickness for wet space construction; a first polymeric adhesive; a first fabric layer fixed with the first polymeric adhesive to a face of said rigid foam core; a first polymeric film on said first fabric layer in which the polymeric film is dimensionally stable parallel to said face of said rigid foam core; and a second fabric layer on said first polymeric film opposite said first fabric layer and forming a first face that is amenable to thin set mortar and related compositions in wet space construction.

1. A waterproofing assembly for a built-in
shower drain which comprises: An upper grate, A drain body, A clamping ring placed between the upper grate and the drain body, an adaptive device configured to connect a waterproofing to a built-in
shower drain, placed between the upper grate and the drain body, which comprises a body made up of an upper section with a through hole and a lower section with a through hole in parallel arrangement at different levels, the upper and lower sections joined together by means of a deformable intermediate section which is capable of folding by means of at least one fold line; and A template piece configured to be placed on the clamping ring, which comprises a body of a rigid material which has an upper surface and a lower surface with a central through hole, the surfaces being separable from one another, the upper and lower surfaces joined together by means of an intermediate section, the lower surface having a plurality of protuberances, in which at least one of the protuberances has a through hole, the adaptive device and the template piece being axially aligned with respect to a drain body and the clamping ring.
Are these the ex Durock
system? Looks like they all have around 14 years of life to them.
