Analyze Claims Of Prior Art: Backpack Sprayer

Analyze Claims of Prior Art Student’s Name Institutional Affiliation Analyze Claims of Prior Art The prior art that I would refer to is a Backpack Sprayer invented by Pedro Wirz in 2005 and patented in 2006. The backpack sprayer is a Knapsack sprayer that uses mechanical means to dispense its content to the plant (Wirz, 2006). Instead of using power to generate pressure like my invention, this sprayer uses the pressure chamber to force the solution out of the tank. It uses the piston inside the cylindrical cap to drive the fluid into the pressure chamber (Wirz, 2006). The backpack sprayer has two independent claims and six dependent claims. The first and the eighth claims are independent claims and claim number two to seven are dependent. First part Claims number two to seven reference independent claim number one. These dependent claims expound on the cap attached to the piston. The location and the functions of the cap are introduced in the last part of the claim number one (Wirz, 2006). The dependent claims further describe the additional features on the cap such as interior flanges, split collar, and their functions. The dependent claims indicate that the cap plays a crucial role in the functioning of the piston. Therefore, although the cap has been introduced in claim number one, it has been further described by the subsequent dependent claims (Wirz, 2006). Claim number 8 on the backpack patent is also an independent claim and has only claim 9 as the dependent claim (Wirz, 2006). Basically, the claim 8 is a repetition of claim 1 with some few changes in the words used, whereas claim 9 is the repetition of claim 3. As indicated above the dependent claims are generally describing the cap that has been introduced in the last part of the independent claims. For instance, the claim number 2 introduces some additional feature in form of flanges. Claim 2 gives the position of the flanges and states that it contacts the piston during the ...
