<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial",sans-serif;mso-ligatures:standardcontextual">In the above example, the alternatively recited limitations are not mutually exclusive but the “at least one of” language allows for multiple

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial",sans-serif;mso-ligatures:standardcontextual">But since (b) and (c) are identical, is that a problem with respect to the validity of the claim or would it be considered definite since if
you have or don’t have (b) you have or don’t have (c)?<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial",sans-serif;mso-ligatures:standardcontextual">Also, I think this could be fixed by a certificate of correction to remove the duplicate limitation, but wondering if anyone has either had some
experience with this or has a different point of view regarding potential issues.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial",sans-serif;mso-ligatures:standardcontextual">Lastly, even if fixable by certificate of correction, since I believe that you can correct the claim at any time, is this something that is better
left alone and only corrected if you think you are going to assert or perhaps license or sell the patent? Or would you be better served to make the correction immediately upon discovery of the error so that the claim is cleaner as soon as possible?<o:p></o:p></span></p>
