This is to confirm our understanding with respect to our representation of you. 1. Nature of Services. Our firm will provide you with patent law legal services, concentrating initially on the , and such other matters as you may refer to us from time to time. To generally acquaint you with the process and cost of acquiring and maintaining a U.S. patent, given below are the steps and legal fees and expenses in a typical patent prosecution matter. We propose to proceed in a step-by-step manner with your prior authorization and you may elect to stop at any step in this process so as to not incur further legal fees: (a) Patentability search – Perform a patentability search to initially assess whether patent coverage seems available for your “invention;” this would include writing a claim to your invention and assessing this claim against the patents that are on file as the U.S. Patent & Trademark Office (USPTO) and giving you an oral report of our findings: Legal Fee –$950 – $2,500 dependent on the necessary extent of the search and complexity of the novel features. If your patentability search were to come back negative, our representation of you in this matter would probably conclude at this step. (b) Preparation and filing of a U.S. Regular Utility Patent Application: Provisional Legal Fee – approximately $2,500 – $5,000; Nonprovisional Legal Fee – approximately $2,500 – $9,000 and depending upon the effort required to fully describe and claim your invention (which often is a function of your invention’s complexity and the completeness of your invention disclosure). Regular U.S. Design Patent Application: $995. Expenses: Fee Small Entity Micro Entity USPTO Provisional Filing Fee $150 $75 USPTO Non-provisional filing fee $860 $430 USPTO Design Patent filing fee $510 $255 Line Drawings Approximately $100/sheet   (c) Response to USPTO Office Action/s which gives the USPTO’s feedback on the Application (A necessary step in >90% of utility applications): Legal Fee – because the amount of work required at this stage will be a function of the USPTO’s feedback, it is difficult to quote typical legal fees for this step; recognizing that a Response to more than one Office Action may be required, it is hoped that these legal fees can be held to $5,000 or less. (d) Filings in Response to a Notice of Allowance & the subsequent Issuance to you of a Patent: Legal Fee – approximately $500, Expenses – USPTO Issuance & Publication Fees – $1,170. (e) To extend the term of the life of your patent to its maximum of 20 years, you will need to pay “small entity” maintenance fees of $1,000, $1,880 and $3,850 or “micro entity fees of $500, $940, and $1,925 on the respective 3rd, 7th and 11th year anniversaries of the date of issuance of your patent. (f) Depending upon your interest in foreign patent protection, within twelve months of filing a U.S. patent application or your invention’s public disclosure, you will need to apply for your foreign patent rights – typically by filing what’s known as a Patent Cooperation Treaty (PCT) Application. Legal Fee – it is hoped the initial legal fees can be held to $1,000 or less, Expenses – typical initial PCT filing expenses are on the order of $3,000. 2. Fees. For the above listed steps 1.b. and beyond, we bill for our services on a monthly basis, calculated in 0.1 increments using the hourly rates set forth below: Matthew Mitchell Hourly rate: $350 Six-minute increment $35 Law Clerk Hourly rate: $90 Six-minute increment $9 We reserve the right to increase our hourly rates from time to time. It may be necessary for additional attorneys of this firm to perform work on other matters that you may refer to us. 3. Expenses. For the above listed steps 1.b. and beyond, you will be charged for our out of pocket costs we incur associated with the services rendered (e.g., USPTO fees, costs for the preparation of patent drawings).   4. Billing. For the above listed steps 1.b. and beyond, we will bill you on a monthly basis for all fees and expenses, which bills will be payable upon presentation. All bills will show the services rendered, the date rendered, by whom, and the cost. We ask that you review each bill promptly when rendered and bring any questions to our attention within thirty (30) days, after which time all bills shall be deemed accurate, fair and reasonable. Unless other arrangements are mutually agreed upon in writing in specific instances, payment is expected within 14 days of receiving the bill. We reserve the right to add interest at a time-price differential calculated at the rate of 1½ percent per month of the balance from the due date until paid to all billed and unpaid balances beginning thirty (30) days following the date upon which such charges are actually billed. It is also understood that this firm shall be entitled to recover reasonable attorneys’ fees and expenses and court costs in connection with any efforts necessary to collect amounts due and unpaid pursuant to any engagement between a particular client and our firm. 5. Credit Card Payment; Prompt Payment Discount; Late Payment Interest charges. All clients may deposit retainers and pay their bills via credit card, using our on-line payment system at: https://www.mipatents.com/payment/. If, after a payment by credit card, you later dispute the charges, unless prohibited by law, you agree not to cancel, revoke or dispute any previously entered charge on your credit card. If you do so, and it is later determined that the charge was properly authorized, you agree to pay all out of pocket fees and costs incurred by Mitchell Law PLLC as a result of the improper cancellation, revocation or dispute. 6. Termination of Engagement. Subject to general standards of professional responsibility of the legal profession, our firm will have the right to terminate our representation of you when such termination is mandated or permitted by applicable rules of professional responsibility, including but not limited to terminating our representation of you if any fees and/or expenses are not timely paid after a statement with respect to them is rendered. Termination of services does not affect your responsibility to pay for the legal services rendered and the costs incurred up to the date of termination.   7. Record keeping; Post termination records. As a service to current ongoing clients, we do not separately charge for record keeping and digital imaging. If you request copies of your file, we generally do not charge for such copies or for emailing a digital copy, however if the volume is significant, we will outsource such copies and you shall be responsible to pay them as ordinary expenses under Section 3 above. In the event this engagement is terminated, your file will either be: (A) imaged and returned to you; or (B) returned to you without imaging. We may electronically scan and store documents related to your matters, and if we do, we may destroy the tangible records or return them to you; provided that, without your consent, we do not destroy original documents – those are typically scanned and returned to you, or in some cases, maintained in physical files at our offices. If we cannot locate you we are entitled to send your physical records to the last known address in our system; therefore it is important that you keep your current address on file with us. 8. Fixed or flat fees. For the above listed steps 1.b. and beyond, we generally work on a time and materials basis. We can perform some services on a fixed fee. In a time and material engagement even if we have estimated the time or cost requirements on a matter, provided a budget, or otherwise responded to a request for a range of expected fees and costs, there is no guaranty that such estimate, budget or other amount will be the actual cost incurred – because often we cannot anticipate when and what action the USPTO and foreign patent offices will take in reviewing and processing any patent applications that we file on your behalf. 9. Retainer. An initial retainer of $______, representing the full and complete cost of filing the U.S. national entry application is payable at the inception of our work in this matter and for you to authorize us to proceed ahead. Thereafter, depending on our expectation of the upcoming workload that representing you will entail, we will ask that this retainer be replenished each month in an amount sufficient to cover these expected, upcoming legal fees. Any moneys remaining in the escrow account upon the completion of our representation of you and after all fees and expenses have been paid will be returned to you, without interest. 10.
