`
`• Claims 10 through 19 are dependent claims that further limit the scope of
`
`claim 6. Accordingly, because they add additional limitations to claim 6,
`
`they do not broaden the scope of original claim 6.
`
`• Claim 20 adds three additional limitations to original claim 6:
`
`o Ethernet network;
`
`o Ethernet data node; and
`
`o
`
`the additional step: (d) determining whether the access device is
`
`capable of accepting remote power based on the sensed voltage
`
`level.
`
`Because all of the limitations of claim 6 are included in new claim 20, claim
`
`20 does not broaden the scope of original claim 6.
`
`• Claim 21 (a) adds the additional limitation "Ethernet data network," and (b)
`
`replaces the phrase "low level current" with the Board's construction of
`
`"low level current" ("a current that is insufficient, in itself, to operate the
`
`access device"). Replacing a phrase with the construction of the phrase
`
`does not change the scope of the claim in which the phrase is found and
`
`therefore does not broaden the scope of the claim.
`
`• Claim 22 sets forth all of the limitations of claim 6 as an apparatus claim
`
`rather than a method claim. As demonstrated in the following chart, claim
`
`22 does not expand the scope of original claim 6 because all limitations in
`
`original claim 6 are found in proposed claim 22:

`Conclusion.
`
`As demonstrated above, none of the Reexamination Reference anticipate or

`make obvious the Challenged Claims of the '930 Patent and the proposed new
`
`claims. Accordingly, the Patent Owner respectfully requests reconsideration and
`
`allowance of all pending claims.
