Office Action

§112
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claims 1-10 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the enablement requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to enable one skilled in the art to which it pertains, or with which it is most nearly connected, to make and/or use the invention. As to claims 1,10, the “sealing device” is non-enabling, as will be shown below in relation to Figure 3. Consider the following: The outer channel 52b is not a channel in Figure 3. Is it merely the lead line? PNG media_image1.png 210 640 media_image1.png Greyscale Nothing identifies water in Figure 3. In effect, how is 52a clean room and 52b not clean room? How is water in the channel 52 such that the division between room 52a and 52b exists? The blade 52 does not divide. Blade 54 does not seem to divide channel 52 into sub-channels 52a,52b, as there is other structure that seem to serve as a wall that separates the sub-channels. PNG media_image2.png 210 640 media_image2.png Greyscale What truly defines the circumferential channel 52 in Figure 3? PNG media_image3.png 158 692 media_image3.png Greyscale PNG media_image4.png 294 556 media_image4.png Greyscale PNG media_image5.png 274 556 media_image5.png Greyscale The sealing device is not described in a manner how such is to be constructed, or even what structure provides for such. As such, there is no enabling example, no reference describes the seal, no obvious manner of experimentation. Claims 1-10 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. As to claim 1, measuring level “at least indirectly” is confusing, as it’s not clear if such includes measuring level directly. The phrase “at least indirectly” does not suggest measuring directly in the context of this application. Understand, there is - - measuring a filling level - - and - - measuring a filling level at least indirectly - - ; but the phrase “at least indirectly” gently infers something (i.e. directly) that there is no clear support for. As to claim 3, “the overflow container” was never introduced. Should claim 3 have depended upon claim 2 which does introduce “an overflow container” (claim 2)? As to claim 5, the term “designed” suggest a human element, and thus its meaning is uncertain in this apparatus claim. Does the reservoir include a circumferential channel? As to claim 6, “preferably” is indefinite. Is the wall rotatable, or isn’t it? As to claim 6, the term “designed” suggest a human element, and thus its meaning is uncertain in this apparatus claim. Is the wall merely configured to be rotatable? As to claim 10, the preamble tags this as a method claim, but it’s not claim what the actual steps are. Note that lines 1-last provide for 2 wherein clauses, and do not add anything additional to a method claim that has not step. The phrase “to be treated” (line 2) suggests a future, and thus is not a step. The phrase “containers are treated” (line 5) seem to define a state, and not a step. What are the steps (i.e. actions) that define “A method for treating containers” (line 1)? The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Shonfield CN 102642799 teaches (Figure 1b) a container 10 in a clean room 12. The seal unit 20 (with reservoir) is supplied with liquid, and is controlled by ball float. However, there are no stations, and the sensor is not in a supply line which is in flow connection with the reservoir. Till et al JP 2007217063 teach a water sensor 38 connected to the source 34 of water which passes to the seal inlet 32. The Reference’s seal is in a rotating conveyor 11 system that treats bottles 2. However, the sensor is not a level sensor. Schoenberger et al 9,045,288 (listed 1449) teaches (Figure 7) positioning a water level sensor 89 within a channel 89 of a seal 86 which employs a blade 83, such used with a container system.
