Therefore, it would have been obvious to one of ordinary skill in the art at the time of effective filing to modify the invention of Bolus to include at least one controller controlling the first and second valves to determine the first and second flow rates of the fluid from each of the first and second channels, wherein the first flow rate and second flow rate control a direction of a resulting stream of fluid as taught by and suggested by Langlais in order to control fluid through the first and second fluid path (Paragraph 0053, This is the same modification as claim 2). Regarding claim 9, Bolus discloses a showerhead (Paragraph 0001) comprising: a plurality of nozzle systems (Each instance of Figure 6 in Figure 5), each nozzle system including at least a first channel and a second channel (The two instances of Figure 6; 48. Paragraph 0071), wherein the first and second channels are angled such that fluid exiting the first channel impinges on fluid exiting the second channel to form a fluid output (Functional Language, the fluid exiting the first channel impinges on the fluid exiting the second channel which forms a fluid output. See Figure 2); a first fluid path (The fluid path from a source to Annotated Figure 6; labeled first fluid input to the first channel) connecting the first channel of each of the plurality of nozzle systems with a first fluid input (Annotated Figure 6; labeled first fluid input); and a second fluid path (The fluid path from a source to Annotated Figure 6; labeled second fluid input to the first channel) connecting the second channel of each of the plurality of nozzle systems with a second fluid input (Annotated Figure 6; labeled second fluid input). Bolus does not disclose a first valve controlling a first flow rate of the fluid flowing through the first fluid path; and a second valve controlling a second flow rate of the fluid flowing through the second fluid path. However, Langlais teaches a first valve (Figure 1; 81) controlling a first flow rate of fluid (Paragraph 0050, 0053) flowing through a first fluid path (The path from Figure 1; 85 to 60); and a second valve (Figure 1; 82) controlling a second flow rate of fluid (Paragraph 0050, 0053) flowing through a second fluid path (The path from Figure 1; 85 to 61). Therefore, it would have been obvious to one of ordinary skill in the art at the time of effective filing to modify the invention of Bolus to include a first valve controlling a first flow rate of the fluid flowing through the first fluid path; and a second valve controlling a second flow rate of the fluid flowing through the second fluid path as taught by and suggested by Langlais in order to control fluid through the first and second fluid path (Paragraph 0053, The modification adds a first valve, second valve and controller).
