Hydrapak Approved for Issuance on Patent

Published August 8, 2011

OAKLAND, CA (BRAIN)--Hydrapak's reservoir closure system and method (Application No.: 11/445,721) has been approved for the issuance as a patent by the U.S. Patent Office.

The closure system and method, first utilized in the Reversible Reservoir II and introduced in 2006, serve as the foundation of Hydrapak’s hydration reservoirs. The newly-approved approved closure system, combined with the patented fold top reservoir (US 6,267,506 B1 issued July 31, 2001), combines a top slider which glides across the fold top reservoir to form a water-tight seal.

Source Vagabond Systems, parent company of the Source line of hydration systems and sports sandals, is suing Hydrapak over a closing mechanism that's featured on Source's Widepac reservoir.

Source's lawsuit contends that Hydrapak's Reversible Reservoir II infringes on the United States patent entitled "Sealing Device for Flexible Liquid Container" (#7,648,276). This patent was issued to Source by the U.S. Patent and Trademark Office on January 19, 2010.

Sam Lopez, director of design at Hydrapak, said, “We welcome the U.S. Patent office’s issuance of our unique design. It is gratifying to have their validation and the security they bear on our intellectual property.

“We look forward to future approvals from the U.S. Patent Office, including potentially the patent applications for our new, ground-breaking Shape-Shift Reservoirs," he added.
