Patents and trade marks
The designs, patents and marks that protect the Duryn One and its cartridge system, listed so anyone can check them. We add to this page as applications grant and remove rights when they end.
Notice. This page is provided to give public notice of the patents and registered designs that cover Duryn products, in accordance with the virtual marking provisions of 35 U.S.C. § 287(a) (United States) and section 62(1) of the Patents Act 1977 (United Kingdom). Duryn products and their packaging are marked with the address of this page instead of individual patent numbers. The table under each product below associates that product with the rights that cover it.
Products marked Patent pending are the subject of one or more pending patent applications listed here. A pending application is not a granted patent. Rights listed as lapsed or expired no longer apply and are kept on this page for a period only so that older products can be traced.
Which rights cover which product
One product, one list. This is the association the marking statutes ask for.

Registered designs and design patents
Design rights protect how the Duryn One and its cartridge look. A design patent (US) or registered design (EU, UK, India) covers the ornamental shape, not the way it works.

Using our names and marks
For press, retailers, affiliates and anyone writing about the product.
Write “Duryn” or “duryn”
The brand is written in lower case in the logo and either way in text. Never “DURYN” or “Duryn®” in running copy; the ® belongs on the mark itself, and only in the countries where it is registered.
“Duryn One” is the pitcher
The product is the Duryn One; the cartridges are the Duryn Clean, Alkaline and Softener cartridges. GravityPlus™ is the name of the carbon-block filtration system, not a product.
Ask before you use the logo
Retailers and affiliates get logo files and product photography from our press kit; use them unaltered. Do not combine the logo with another brand's name or mark.
Compatible does not mean Duryn
No third-party cartridge fits the Duryn One, and no one is licensed to make one. A product described as “Duryn-compatible” is not ours, and we would like to hear about it.
