Here is the situation: my patent has gone through several Office Actions (OA).
In the first 2 Office Actions, the examiner found some legitimate arguments against my application and I have amended some claims accordingly.
Then the examiner cited parts of another patent as prior art for obviousness, and to sustain his rejection, quoted sections of this patent as arguments against my invention.
I have carefully considered his arguments, made a detailed and thorough analysis of the cited prior art and replied to said OA by respectfully arguing against each argument advanced by the examiner. (It appeared that the examiner hadn't read in details the prior art but merely referred to some drawings and grasped vague concepts of the prior art, so it wasn't too difficult to provide counter-arguments). In view of my arguments, my invention is non-obvious.
But in the latest OA, the examiner totally ignored my arguments against his (as if he himself hadn't advanced any prior arguments) and rejects my invention on obviousness grounds simply quoting the prior art he had already cited.
What steps could I take so that my arguments be taken into account, so that they be heard? I am in the final OA...
