I think you're attacking the Examiner's reason for combining the secondary (disable A/D) ref with the primary (receiver) ref. Am I right? <br /><br />Or are you arguing instead that the secondary (disable A/D) reference does not teach the element in claim 15? "<br /><br />I'm taking as a given the argument has already been made that the reference does not teach selectively disabling one or more components of an A2D converter.<br /><br />Then I am pointing out that, even if the reference did teach selectively disabling when diversity capability is not required, that's not the same thing as selectively disabling to vary the gain of the receiver. The Examiner can't take the teaching of selective disabling (even if it does exist in the reference) and use it to supply the selective disabling of the claim, because that is hindsight reasoning. He has to find another reference that provides the teaching of selective disabling of the A2D converter component(s) for the same purpose.<br /><br />As for this wisdom from our anonymous friend who speaks what everyone should know (but that some CAFC judges apparently don't know):<br /><br />"I know it's tempting when it just feels obvious, but I don't think you get to fabricate elements out of thin air, and then justify them because the results are predictable." <br /><br />I refer you to last weeks CAFC decision in Tokai Corp. v. Easton Enterprises, in which the panel did just that. The defendant couldn't present prior art that showed the claimed element, but presented art showing a different element that performed the same function in a different way. The CAFC held the claim obvious under summary judgement becase a "high school shop class" had the skill to make the different element that never existed before, and the results were predictable. They didn't care that the patentee's invention was wildly commercially successful and that everyone copied.TINLA IANYLhttp://yahoo.comnoreply@blogger.comtag:blogger.com,1999:blog-6733236595417664807.post-29153649304184330722011-02-10T15:53:55.651-05:002011-02-10T15:53:55.651-05:00>critical point is that the reference relied

That's hindsight reconstruction, since your only source for the "selective enablement of an A/D converter" is the claim itself. In my opinion, a correct use of the "predictable result" analysis would look more like:<br /><br />Reference A shows everything except selective enablement of an A/D converter. Reference B shows selective enablement of an A/D converter, in a different but related context. It would have been obvious to add selective enablement of the A/D converter, as shown in B, to A's similar system, since the results would have been predictable and the modifications were well within the skill of one of ordinary skill in the art.<br /><br />I know it's tempting when it just feels obvious, but I don't think you get to fabricate elements out of thin air, and then justify them because the results are predictable.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6733236595417664807.post-2584812531375330662011-02-10T15:07:21.076-05:002011-02-10T15:07:21.076-05:00>claim literally reads on the case that all

"Finally, one minor qu...Regarding this point:<br /><br />"Finally, one minor quibble. If you read the claim closely, it says disabling one or more components of an A/D converter. The reference described, and the Board discussed, options for building a receiver using one or two A/D converters. There's a difference, right?<br /><br />Now, the reference certainly didn't teach disabling components of an A/D converter, so the Board properly reversed. But was that an accident? Did the Board go down the wrong track because they didn't read the claim carefully? Makes me wonder. "<br /><br />I would expect an Examiner to reply that the claim literally reads on the case that all components of the converter are disabled by disabling the converter. The claim does not require the capability to disable only one component of the converter, or a subset of the components. Thus, a prior art device that has two converters, in which one of the converters can be selectively disabled, would still infringe the claim. That which infringes, if earlier, anticipates. That which is obvious at the earlier time, and would infringe, also invalidates. So if you agree that the ability to selectively disable one of multiple converters would be obvious, then the claim should still be obvious, because disabling the converter disables all components of the converter and fulfills the claim limitations.<br /><br />I think the critical point is that the reference relied upon teaches that one converter can be used instead of two when no diversity capability is required, and not to vary the gain of the receiver. Purpose matters. Causation matter. One cannot lift an element from the prior art without considering the purpose for which it was used. Otherwise you have impermissible hindsight reasoning. <br /><br />The MPEP instructs Exmainers to respond to Applicants' hindsight reasoning assertions as follows:<br /><br />"7.37.03 Unpersuasive Argument: Hindsight Reasoning<br />In response to applicant's argument that the examiner's conclusion of obviousness is based upon improper hindsight reasoning, it must be recognized that any judgment on obviousness is in a sense necessarily a reconstruction based upon hindsight reasoning. But so long as it takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made, and does not include knowledge gleaned only from the applicant's disclosure, such a reconstruction is proper. See In re McLaughlin, 443 F.2d 1392, 170 USPQ 209 (CCPA 1971)."<br /><br />I read the McLaughlin case, and it specifically says that the hindsight reasoning was permisible because the prior art used those components used int he reconstruction for the same purpose. I don't think that it is the fault of Examiners that the MPEP instructs them to take a quote form a case out of context and use it willy nilly, but I think this point about the purpose for which the component was used in the cited reference is one that needs to be driven home in our responses.TINLA IANYLhttp://yahoo.comnoreply@blogger.com
