What facts lead you to beleive that the Examiner is gaming the system as opposed to acting in accordance with PTo procedure?
I'll take a stab at that.
1. If the sole amendment is recasting a dependent claim as an independent claim, there are no new limitations that the examiner must search.
Yes, if any other claims depend on the newly independent claim, there might be new combinations that haven't been searched. To that, I have 2 thoughts.
First, somewhere in the MPEP, examiners are instructed to glean from the specification what the applicant might do in response to a rejection and search for limitations and/or combinations the applicant might be likely to make -- to reduce the number of iterations of examination. So, really minor changes, even substantive ones, shouldn't require extra work if the letter of the MPEP were followed during examination.
Second, my unscientific survey of Office Actions over the last 18 years says that, particularly in recent years, that any real effort or thought toward establishing obviousness of any combination of any teachings appears in 5-10% of all Office Actions. I typically see some arbitrary and perhaps imagined benefit from the combination. That's it -- not even the perfunctory allegation that the benefit was known to those of ordinary skill in the art(s) at the time the invention was made, let alone some showing that the benefit is actually real. I've even had an examiner recently inform me that the combined references don't even have to be capable of actual physical combination and use together -- just that they provide some conceptual framework in which the ordinarily skilled artisan would think, "Yeah, those could maybe work together somehow."
So, if all an examiner has to do is take the current inventory of teachings and clip them together like Legos, there's no need for a new search.
I've even had an examiner agree to remove a 102(e) rejection after final if I submit a particular amendment. When I did, he refused to enter it, saying it would require a new search. His supervisor (also present at the interview and witness to the agreement) supported that. So, apparently, with the 102(e) rejection (the only grounds for rejection at the time) removed, the case should be allowed, right? Nope. After final, not rejected, not allowed.
2. The examiner could easily suggest an examiner's amendment to cancel all claims depending on the amended claim. I suspect that never happens because allowing a case is very difficult for the examiner and an RCE is rather helpful to the examiner.
I would go so far as to say that "gaming" after final practice is a pervasive part of USPTO patent application examining culture and has been for many, many years. At the same time, my arguments aren't being taken seriously until I file a Pre-Appeal Brief Review request anyway, so none of this affects my practice much as I try to get to PABR and the appeal process as quickly as possible.
Regards.
