<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>
<ul style="margin-top:0in" type="disc">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo3">Be careful how you specify which claims are generic and which read on the selected species. If the species are not mutually exclusive, e.g., the system can have P1 and P2 at the same
time, then you want to make sure to include the claims that specifically relate to P2 as being generic\u2026 and maybe even indicate that claim 2 is generic and reads thereon (depending on your specific claims/situation).<o:p></o:p></li></ul>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We leave claim 2 as it is. Right? <o:p></o:p></p>
<ul style="margin-top:0in" type="disc">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo3">Yes<o:p></o:p></li></ul>
<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>
<ul style="margin-top:0in" type="disc">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo3">Yes, if P1 is free of the art, then the Examiner searches another species. Thus, you may want to specify the order of the species that you would like the Examiner to search next.
I often do this and usually the Examiner will be nice and search in the order of preference I indicate.<o:p></o:p></li></ul>
<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>
<ul style="margin-top:0in" type="disc">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo3">I advise applicants to pick/decide based on the following (order of preference/importance): 1) the preferred species that is likely to be the commercial embodiment and/or 2) the species
that is specifically exemplified in the detailed examples (bc if one runs into a written description or enablement rejection and can\u2019t point to specific support/detailed examples\u2026 one will have significant challenges)\u2026 then 3) the species that the applicant
is quite sure will be free of the art.<o:p></o:p></li></ul>

<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>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">(I understand about traversing, but I am trying to be sure about what to do with the claims)<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>
