Appeal No. 2004-0891 Application No. 09/810,539 any external conduit such that all air and smaller particles of waste material vent outside the room.” Appellant’s figure 3 shows component 22, which is described on page 4 at line 11, as an outlet. Figure 3 shows that this outlet does have a length. In Merriam-Webster’s Collegiate Dictionary, Tenth Edition (2000), the word “conduit” is defined as “a natural or artificial channel through which something (as a fluid) is conveyed” or “a pipe, tube, or tile for protecting electric wires or cables.” In the American Heritage Dictionary, Fourth Edition (2000), the word “conduit” is defined as “a pipe or channel for conveying fluids, such as water” or “a tube or duct for enclosing electric wires or cable”.

We appreciate that claim 1 recites “without any external conduit”. However, claim 1 also recites an air exhaust outlet, and as depicted in figure 3, this air exhaust outlet 22, has a length, and we can interpret it as being a pipe of some sort. In light of the above interpretation of claim 1, we provide the following. Figure 13 of Hamrick depicts tubular fitting 116.

In this way, communication is established between the air exhaust side of fan motor 30( and the atmosphere in a corresponding room. Appellant has not established any patentable difference between this configuration and their claimed outlet 22. Claim 1 requires that outlet 22 4Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
