While it is true that Graham is the basis for obviousness, KSR does not require doing the analysis completely from scratch everytime the examiner does not use TSM. KSR describes a number of methods for analyzing obviousness without employing TSM. Yes, those methods do require specific fact finding, but arguments that rely solely on the examiner not citing a motivation to combine are not going to be successful if the examiner is not doing a TSM based analysis. Instead you have to identify specific holes in the analysis that the examiner did use.
Of course. If obviousness is not based on TSM, failure to cite a proper TSM does not vitiate the finding of obviousness. However, I was addressing the tossing up of any motivation at all for combination regardless of its source.
For example, if the examiner's indicates that your invention merely uses a known technique to improve similar devices (methods, or products) in the same way (See MPEP 2143), it would be unconvincing to respond that the examiner did not establish a motivation to combine ala TSM.
In my mind, that's a variation of a TSM analysis. For example, a teaching of a yard stick and a teaching that a meter stick can be extended by connecting multiple meter sticks end-to-end with scotch tape can be viewed as providing the motivation to extend a yard stick by taping multiple yard sticks end-to-end.
However, I'm not aware of any obviousness analysis other than TSM (or similar variants such as the one Isaac identified) in which detailed factual findings of Graham (including the level of ordinary skill in the art(s) at the time the invention was made) are not required.
I think the PTO understands this as evidenced by the proffering of motivations to combine, even if purely imagined motivations without adequate support in the record.
I'd also say that the TSM test goes further than that required by Graham. Accordingly, I think a solid TSM analysis is difficult to overcome, more difficult that an ordinary obviousness finding adhering strictly to Graham.
DDP described a rejection where the examiner said "PHOSITA would combine Ref A with Ref B to arrive at your invention because Ref B shows it is possible to do X, therefore, if PHOSITA desired to do X to Ref A, he could". The quoted statement strongly suggests to me that the Examiner was doing fact finding supportive of a "uses a known technique to improve similar devices" type rejection. If so, I wouldn't expect the examiner to back off of the rejection even if you argue that no motivation to combine was provided.
I might have misread that. I thought DDPM was saying that the examiner equated "feasible" with "obvious". Some examiners here have said that, for some arts, feasible = obvious.
I didn't think of it as a "known technique to improve analogous things" rejection. As I try to wrap my mind around that sort of obviousness analysis, my mind leaps right to doctrine of equivalents analysis -- does the same thing in the same way to achieve the same result (with a healthy dose of "substantially"s sprinkled in there).
A couple decades ago, I wrote a paper suggesting using some obviousness analysis to determine equivalence. That idea popped up in dicta (dissenting or concurring opinion) in the Fed Cir. a few years later -- sorry, don't have the cite. Now, it's coming full circle -- using DoE analysis to determine obviousness.
I think it was Learned Hand that said "that which infringes if later, anticipates if before." My thought was to stretch that symmetry to equivalents and obviousness.
"Trade-offs often concern what is feasible, not what is, on balance, desirable. Motivation to combine requires the latter." Winner Int'l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 (Fed. Cir. 2000)
Looks like good authority to me. However, to use it, you'd want to Sheppardize it to make sure it's still good law. It expresses the law as I understand it.
