This webpage is provided to satisfy the virtual patent marking provisions of various jurisdictions, including the virtual patent marking provisions of the America Invents Act (35 U.S.C. § 287). The following list may not include all patented products and other products not listed here may be protected by additional patents. The patent process is dynamic and this list and the association between products may change as a result of but not limited to the following: filing, publication, issuance, licensing, product changes, expiration, abandonment, and other circumstances. This list is updated from time to time but may not be fully up to date when you visit this page. The status of patent applications on this list may change and patents may have issued in the United States and elsewhere that are not included in this list.
