Weatherford is marking the products specifically identified under the Product Lines or Business Units below pursuant to 35 USC §287(a) by associating each identified product with one or more US patent(s) that cover or are for use under such patent(s).

If a product is not specifically identified on this website, or is not otherwise marked with a patent number, then it is not currently being so marked. For the purposes of this website, only US patents are listed.
