Well, hopefully the attorney can craft a claim that reads on B, B1, B2, and B3 -- some generic, umbrella term/phrase.
That's what the attorney should do. And if they do that, then they avoid the problems that I bring up. But what's the point in adding B1, B2, and B3 to the specification if those are attorney embodiments and you can claim B in a broad manner that encompasses all of B, B1, B2, and B3?
I could make a very illustrative example of the problems this creates if it weren't for that pesky Festo case.
Well, I wouldn't recommend approach. If the attorney knows that B1, B2, and B3 are feasible alternatives to B and fails to cover them in the claims, two things have happened.
Jim, that's a claiming issue and not a matter of writing the spec.
But let's consider some examples for which I probably don't know the answer to and am just feeling a bit argumentative today:
A tool comprising:
a lever having first and second ends;
a dohicky on the first end of the lever; and
a grip portion defined on a second end of the lever.
The client invented a pair of sharp edges that join together to cut an article to be worked on. That's what the attorney calls the dohicky. But the attorney realizes that the dohicky could also be a pair of cup-shaped members that join together to form a scoop. The client really doesn't care because the scoop embodiment isn't in the client's business plans. So one day the client (now patentee) files suit against an accused infringer. The accused infringer argues for claim construction of dohicky to include both the cutter embodiment and the scoop embodiment. And so as to not complicate things, let's assume that there is essentially no prosecution history. The patentee can't really defend this claim construction because, after all, both embodiments are written in the specification as dohickys. Now the patentee has an inventorship problem. Is it invalidating of the patent? Probably not, there is no intent to deceive. But I think this academic example does illustrate one of the problems of attorney-introduced embodiments.
Now let's consider another example. Attorney adds scoop embodiment, patent application gets filed, three years later the USPTO rejects. Attorney has left for the carribean and cannot be reached. Attorney B picks up the case, says let's amend to include the scoop embodiment. Client, ignorant or forgetful of either the facts or the law, agrees to the amendment. Again, now we have an inventorship problem.
Finally, let's consider the example where an attorney (heaven forbid) uses MPF language or functional language so broad that MPF treatment is appropriate. In this case, if the attorney has introduced alternate embodiments to any of the claim elements that are subject to MPF treatment, then I would argue that by rule the attorney has to be listed as an inventor.
