Simply preparing a patent application for filing can take a
non-trivial amount of time.  I'd suggest that you should ask your
patent attorney whether he is planning on filing internationally, or
just in the US.  

If he (or she) is only planning only in the US, unlike the rest of the
world, the US is not a first-to-file, so as long as you have proof of
when you invented it --- for example, getting a description of your
invention notarized --- you might be able to get clearance from your
legal department to submit the patch while the patent application is
getting prepared.

If your attorney is not willing to do this, all I can suggest is that
you ask him to ask his opposite numbers at other open source companies
how they handle this situation at a future Linux Foundation Legal
Summit.  I can assure you there are far more rational ways of handling
this than forcing people to wait until the patent application is
actually filed.

No argument here.  It's just that there are better ways of doing
things than waiting until after the patent application is fully
drafted, all of the engineering drawings are done, the language of
patent claims are fine-tuned, etc., all of which can take a long, LONG
time, depending on how busy your patent attorney and his (or her)
staff might happen to be.
