<p>Well, could you file 1 divisional with all the unelected claims,
and force them to split it up again?<br>

<div>Advice I got some years back from one Canadian
counsel as to whether one could rely on a PCT
finding of lack of unity to avoid the dreaded
double-patenting rejection was that they hadn't
found sufficient caselaw to provide a definite
answer. As such, their advice was to enter w/
claims to all the inventions (although not
necessary dependent claims, since CA no longer
allows cramming in as many claims as possible w/
no excess fees) and leave it to the examiner to
restrict. Slower, but safer. Of course, if every
applicant follows this, the issue of whether or
not a PCT lack of unity suffices will remain
unanswered.</div>

</div>
<div dir="ltr">Background --> Canada has a
known challenge related to double patenting,
and unlike USA there is no objection of
submitting a terminal disclaimer to

<div dir="ltr">As such it is not uncommon for
applicants to provoke a 'unity of invention'
objection - the CA examiner then splits it
up into many inventions, and then neither of
them </div>

applicant just file many divisionals..</div>

<div dir="ltr">I think if I then file 6

paid now, instead of 'spacing it out' over

<div dir="ltr">MY QUESTION --> instead of
filing 6 divisionals at ONCE (i.e. in

first a divisional, and then a divisional of

divisional of divisional), and so one.</div>
<div dir="ltr"><br clear="none">
</div>
<div dir="ltr">If I file in SERIAL (i.e. 1st

Japan treat divisionals and
divisionals-of-divisionals the SAME. In
