<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So, if you have claims like:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Claim 1 recites "measuring one or more physical properties of a blob...", and
<o:p></o:p></p>
<p class="MsoNormal">Claim 2 recites "the system of claim 1, wherein physical properties comprise P1, P2, P3, and P4."
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The species restriction is on the properties P1, P2, P3, and P4 in claim 2. The examiner says to pick one of them.<o:p></o:p></p>
<p class="MsoNormal">And we elect property P1.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The species election just says that claims 1 and 2 read on the invention. Right?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We leave claim 2 as it is. Right? <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I.e., after electing P1, we leave claim 2 as is, and it will be examined only to the extent it covers the elected property P1. Is that correct?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Assuming the disclosure is enabling for each of the properties (P1 \u2026 P4), is there a suggested strategy for which one to elect?<o:p></o:p></p>

<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>
