*  The patentability search and opinion fees are based upon a typical patent search.  The patent searches may be performed in-house or by an independent patent searcher depending upon availability - if you have a preference please indicate the same in writing when providing your retainer for the patentability search.  For complex patent searches, we will provide you with a fee quote for performing the patentability search and opinion. For the Rush patentability search and opinion, the Invention Recording Document and full retainer must be received by at least 1 pm CST the previous day.  The patentability search opinion and top 3 search results are e-mailed (PDF format) to client upon completion.

Note: The fees above are subject to change without notice and do not include USPTO government filing fees, subsequent prosecution fees, issue fees, maintenance fees, office service fees or enforcement fees. Retainers are typically required before performing services or making payments to the USPTO. We charge interest at 7.0% per annum for accounts past due for more than 30 days.  We typically report all correspondence via e-mail, unless postal, fax or courier are expressly requested in writing (additional fees may apply).  Neustel Law Offices, LTD does not accept liability for failure to implement instructions received within 5 business days of a deadline.  We recommend sending all instructions via e-mail or fax not less than one (1) month prior to any deadline, and obtaining from our law firm a prompt confirmation that we received the instructions.
