The first point in the scope of ask patents - finding prior art, is, essentially, dead. We have a handful of questions asking for prior art each year, and no good answers to those (that I would remember) in the past years.
The second point has, in practice, been broadened to include patent question for all the world.
The third one, specific interpretations of specific claims, I don't think that has ever been done on ask patents. It's way out of what a community could achieve without dozens of experienced patent attorneys with to much time on their hands.
All in all, the still active part of ask patents would be a perfect fit here and could benefit from the larger community.
Additionally, this site would benefit from some patent people answering the patent tag questions.
-> Merge!
As to the specifics, tags are more of a nice to have thing over at ask patents, they aren't used consistently and mostly a few broad tags that don't help with anything are used for questions - and/or some new/small tags that, well, describe the question but aren't useful as tags. So merging ask patents without the tags would be my preferred solution.
The scope should be any question about patent law, which would be on topic here anyways and additionally proceedings before the (us)pto (epo, etc. maybe). I don't know if that would be on topic but I vote to include it.
Ask patents has maybe a dozen active users, I remember exactly one time when we were able to close a question without moderator intervention, but we are generally able to answer the (rather few) good questions, so law.SE won't be overwhelmed by patent stuff.
