Patents

This website provides notice in compliance with 35 U.S.C. §287(a) by associating various patented products with U.S. patent numbers. To reduce waste and promote efficiency, instead of relabeling products as patents issue, unpatented products may be labeled with the address of this website so that patent markings, if appropriate, can be provided virtually. The presence of a label on a product directing you to this website, without the presence of a patent number associated with that specific product, means that the product is not marked, virtually or otherwise, under 35 U.S.C. §287, 35 U.S.C. § 292 or other applicable patent marking laws. Access to the virtual patent markings is provided at no charge to the user.


The products listed are generally organized by model name, and associated with the listed patent numbers. To locate a patent marking associated with a product, find the model name listed on the product or product packaging and search this website for the model name to identify the product’s virtual patent marking. These virtual patent markings will be updated from time to time for a variety of reasons, including, but not limited to, patent filings, product changes, patent licensing, patent expirations and patent lapses. The markings may not be up to date at the specific time you visit. The markings may not be exhaustive; and patents may have issued in the United States or elsewhere that are not identified on this website. Absence of a patent or patent application from this website does not prevent enforcement of any and all available legal rights associated with those patents and patent applications.
