 Swimwaysという会社が特許訴訟を起こしたようだ。
 この会社は、ウォータフロート(浮輪の類?)を販売している。

 本件に関する特許情報は以下のページに公開されている。
 日本の特許も3件提示されている。積極的な知財活動をしてるという印象を受ける。

 なお、SwimWays®, Kelsyus® and COOP®の3つのブランドを使っており、日本ではケルシウスで出願しているようだ。

1.
 A collapsible device, comprising:
 a panel having a central portion and a perimeter sleeve, said panel being permeable to a liquid;
 a spring coupled substantially around the perimeter of the panel and moveable between a coiled and an uncoiled configuration, said spring being coiled while in a collapsed configuration and being uncoiled while in an expanded configuration; and
 an inflatable bladder disposed circumferentially about, and being encapsulated within, at least a portion of said perimeter sleeve, said inflatable bladder configured to support a body weight of a user disposed on the panel.

 1.
 An apparatus, comprising:
 a first flexible material having an outer perimeter portion, the first flexible material having a maximum length greater than a maximum width of the first flexible material, the first flexible material having a centerline defined along the maximum length of the first flexible material;
 a second flexible material having an inner perimeter portion and an outer perimeter portion, the inner perimeter portion of the second flexible material and the outer perimeter portion of the second flexible material collectively defining a sleeve, the inner perimeter portion of the second flexible material being fixedly coupled to the outer perimeter portion of the first flexible material, the second flexible material having a pillow portion adjacent the sleeve, the second flexible material being different than the first flexible material;
 a first inflatable bladder disposed within the sleeve and forming a closed loop having an interior region,
the apparatus having an extended configuration when inflated for use in water and a collapsed configuration when not inflated, the first inflatable bladder being a sufficient size when inflated to maintain the apparatus in the extended configuration and support the weight of a user of the apparatus when the apparatus is disposed in water and the user is disposed on the apparatus; and
a second inflatable bladder disposed within the pillow portion, at least a portion of the second inflatable bladder being disposed outside of the interior region, the second inflatable bladder having a maximum width greater than a maximum length of the second inflatable bladder, the second inflatable bladder having a centerline defined along the maximum length of the second inflatable bladder, the centerline of the second inflatable bladder being substantially aligned with the centerline of the first flexible material.
