Disclaimer..This IMHO no expert...
1st the 336 is our valueable patent (this has been stated by many poster and experts... ) IMHO it would have very lttle $$ impact if we it becomes weaker after the PTO action...The phrase "final rejection" occurs if one claim is rejected... IMHO the PTO does seems to take the approach of having the patent owner prove why prior art should be dis allowed.... it seemed that way w/ 336... the 890 is not rejected... it may weakend it may be stregthned...(yes they may rewrite claims to make them stronger,,,(please do not reply to this if you do not like the words "stronger" or "weaker" for those people substitue what phrase you would like) ...
for me this has no negative effect.... it only seems to par for the course... another delay... I am confident in the MMP.... I am frustrated with the timing...& the issues .... money or the chance to make money has a way of causing people to fix the issues.....
all IMHO...
