I don't need motivation if there are predictable results.
I am very confused by this, much like JimIvey. In my opinion, you do not need
explicitmotivation if there are predictable
beneficial results. That's because
predictable beneficial result is in itself a motivation to combine. And I think you
alwaysneed motivation. I would split these type of teachings into opposite groups, for and
against patentability.
For patentability: teaches away from combining references. Most of the time implicitly
by pointing out the drawbacks of such combination. So there are predictable results,
and they discourage a POSITA from combining the references.
Against patentability: teaches in favor of combining references. Most of the time implicitly
by pointing out the benefits of such combination. AKA motivation to combine. Again, there
are predictable results, and they encourage a POSITA to combine.
I am confused how one can lump both positive and negative predictable results together...
I think when one says "predictable results" what is meant is that the patent application
doesn't teach benefits of the combination that exceed what's predictable. So it's sort
of the next layer of argument. If it is established that the prior art does provide at least
some motivation in favor of combining the references, the next question is whether the
application discloses benefits that far exceed the predictable benefits (unexpected
results). I do not understand how showing that prior art teaches drawbacks of the
combination (teach away) supports an argument that prior art teaches benefits
of the combination, and invention benefits do not exceed those (predictable results)...
Thank you KSR! Though you might have an argument for inoperable in your example.
So what is your claim in your example? Wood x with holes of type y are a spacing of type z.
And ref A teaches the wood x at the bottom of the hull of a boat.
And ref B teaches holes of type y at a spacing of type z.
Teaches away? Most definitely. Predictable? Yes.

Though I can imagine other rebuttals would be more persuasive. Like... The boat is only one embodiment for utilization of the wood.
I am not sure that's the claim JimIvey had in mind, but I am even more confused by the need
to include ref A in the rejection. Seems like ref B + obvious to try is a simpler argument. The
patentability would decided by existence of unpredictable results compared to what is disclosed
by ref B when it's applied to wood x, rather than some other materials.
