Album: Bonzer Rip-off

A few days ago, Chuck Monson from Rotovac stated, “Eriks Zipper patent is on his reversable round glides. He did not invent nor did he patent the dual port concept. Dual port was patented in the 70&#039;s and has since expired which allows anyone to make, use and sell it.” In my opinion, his comments about what the Zipper’s patents cover versus what is included in his Bonzer rip-off are not accurate. In fact, none of the claims of the two Zipper patents are simply directed to carpet cleaning / vacuuming device having dual suction ports, nor does the existence of the Koellisch patent from 1973 automatically and necessarily render every possible use of dual vacuum ports in a carpet cleaning apparatus non-patentable and in the public domain. His statements to this effect are false.<br /> <br /> Rather, the broadest (independent) claims of the Zipper’s first patent 7,761,955 are directed to a carpet cleaning apparatus including several components, e.g., a vacuum head with two vacuum ports, an elongate solution manifold disposed between the two vacuum ports, elongate glides with suction openings, and with lower surfaces that extend below the bottom face of the vacuum head, etc., while the dependent claims of this patent identify other significant features, including a non-fixed handle connected to the vacuum head, adjustable means (wheels) for facilitating movement of the vacuum head over carpeting, etc. For at least these reasons, it is my opinion that the claims of the Zipper’s first patent 7,761,955 remain valid/patentable in spite of the Koellisch patent, and it would be necessary for a Court/jury to otherwise determine that the claims of patent 7,761,955 are invalid before it would be accurate for anyone to state that use of dual vacuum ports on a carpet cleaning apparatus such as claimed in patent 7,761,955 is simply available for anyone to copy.
