<div>Yes, theoretically this is proper use of election of
species (EoS is common for Markush groups, for instance).</div>

<div>The main constraint is "mutually exclusive." So to
change your hypo slightly, "wherein the writing instrument
produces a black line or has a six-sided barrel" wouldn't
be electable because those two aren't mutually exclusive.<br>

Looking for some guidance. Is it proper for an
examiner to issue a species restriction where all of the
supposedly different species are present in the same
dependent claim (as opposed to separate dependent
claims)? <br>
<br>
For example, if claim 1 recites a "writing implement"
and claim 2 says, "the system of claim 1, wherein the
writing implement is one of a pencil or a ball point
pen"? I am used to the type of species restriction
issued involving , for example, claim 2 stating "the
system of claim 1, wherein the writing implement is a
pencil" and claim 3 stating "the system of claim 1,
wherein the writing implement is a ball point pen."<br>
<br>
NOTE: I am not concerned with the propriety of such
restrictions or the arguments that can be made against
them (thank you David for your repeated guidance to the
group on those points), only the specific situation where
the supposed different species are all recited in the same
claim.<br>
<br>
Thanks in advance!<br>
<br>
