Carlson Pet Products issued US patent for 'barrier with panels sliding parallel'

ALEXANDRIA, Virginia , January 15, 2014 () – United States Patent no. 8,627,603, issued on Jan. 14, was assigned to Carlson Pet Products Inc. (Longboat Key, Fla.).

"Barrier with panels sliding parallel" was invented by Mark A. Flannery (Longboat Key, Fla.) and Porter R. Million (Chaska, Minn.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A barrier employed to keep children and/or pets in or out of certain areas in the house. The barrier includes four panels. Two main panels slide parallel to each other to lengthen or shorten the barrier as a whole. Two side panels stabilize the main panels and extend to the front and rear faces of the main panels to provide a self-supporting in-house barrier. Each of the panels includes a wooden frame. The wood lends less weight, less sharp edges, and more pleasing aesthetics than, for example, a metal gate."

The patent was filed on May 31, 2011, under Application No. 13/149,721.
