Contract analysis

I. PURPOSE This memorandum summarizes the current accounts receivable status for the Optiwave Semiconductor Corp. ("OWS") patent prosecution engagement (C&H Matter No. 1014-00005), analyzes the composition of the outstanding balance, recommends a phased collection strategy, and addresses the ethical considerations arising from the intersection of unpaid fees and our continuing professional obligations during the dorm

II. ENGAGEMENT BACKGROUND A. Engagement and Billing Structure The firm's engagement with OWS for patent prosecution services was formalized through an engagement letter executed on February 10, 2022, which was countersigned by Marcus Whitfield, General Counsel of OWS. The engagement was formally opened in the firm's matter management system on February 14, 2022, under Matter No. 1014-00005. The staffing and billing s

III. OUTSTANDING BALANCE — DETAILED BREAKDOWN A. Summary. The total outstanding balance on the OWS engagement as of November 1, 2024, is composed of two categories: unbilled work-in-progress and unpaid invoices. The breakdown is as follows: Each component is discussed in detail below. B. Unpaid Invoices Two invoices have been issued to OWS on this matter and remain unpaid. Both invoices were issued in the ordinary co

IV. COLLECTION EFFORTS TO DATE A. Billing Communications Sent The firm's collection efforts on this matter to date have been limited to standard billing transmittals and informal follow-up, as summarized below: • Standard invoice transmittals. Invoice No. 2023-07-04187 and Invoice No. 2023-08-04187 were transmitted to Sandra Koh at the client billing address in the ordinary course upon issuance in August and Septembe

V. RECOMMENDED COLLECTION STEPS Based on the foregoing analysis, the undersigned recommends a phased collection strategy designed to escalate the firm's collection efforts in a manner that is proportionate, professional, and consistent with the firm's ongoing obligations to OWS as a client. The recommended steps are organized into immediate, medium-term, and avoidance categories. A. Immediate Actions (November–Decemb

1. Finalize and issue the WIP invoice. The $34,218.50 in unbilled work-in-progress should be converted to a formal invoice — proposed Invoice No. 2024-11-04187 — and transmitted to OWS in the standard manner. Finalizing the WIP will formalize the receivable, bring the full outstanding balance into the firm's accounts receivable tracking system, and start the clock on any applicable late-payment provisions under the e

2. Invoice the emergency B1 extension. A separate invoice should be issued for the October 18, 2024 emergency extension filing, including the $2,560 USPTO disbursement and the associated attorney time (estimated at 1.0 to 2.0 hours of associate time at $427.50/hour). This invoice should reference Sandra Koh's October 15, 2024 email authorization and should be transmitted promptly. Given that this work was performed o

3. Escalate to General Counsel. A formal written collection letter should be sent from the undersigned to Marcus Whitfield, General Counsel of OWS, with a copy to Sandra Koh, summarizing all outstanding amounts, attaching copies of the unpaid invoices, and requesting payment within thirty (30) days. The letter should be professional in tone and should emphasize the following points: • The firm's continued commitment

4. Confirm billing contact with the CFO's office. The escalation letter to Marcus Whitfield should include a request that he involve Daniel Everhart (CFO) in the payment discussion. The budget freeze is fundamentally a financial and PE-driven constraint, and resolution will likely require the CFO's involvement and, potentially, an exception request to Veltrano. Sandra Koh has been unable to secure payment authorizati

1. Structured payment plan. If full immediate payment is not feasible given the ongoing spending restrictions, the firm should propose a structured payment plan to OWS. A reasonable arrangement might include three equal monthly installments over a ninety-day period, designed to clear the outstanding balance by the end of Q1 2025. The payment plan should be documented in writing and should include an acknowledgment of

2. Tie collection to reactivation. The imminent critical deadlines in the OWS patent prosecution docket — most notably, the A1 absolute deadline of March 9, 2025, and the B1 deadline of April 21, 2025 — will likely require substantial additional expenditure. Based on our assessment of the scope of the required Office Action responses, the A1 response alone is likely to require $22,000 to $30,000 in attorney fees and

3. Engagement letter review. The February 10, 2022 engagement letter should be reviewed in detail for any provisions relating to: • Late-payment interest or finance charges; • The firm's right to suspend services in the event of non-payment; • Retainer or deposit requirements that may be invoked prospectively; and • Any other contractual remedies available to the firm. If the engagement letter contains a late-payment

1. Referral to an outside collection agency. Referral to a third-party collection agency would be disproportionate for an outstanding balance of this magnitude, would likely generate a negative reaction from OWS and Veltrano, and could irreparably damage the client relationship. The firm has historically had a positive and productive relationship with OWS, and the non-payment is policy-driven rather than reflective o

2. Filing of any lien (including a charging lien on work product). Assertion of a retaining lien or a charging lien on prosecution work product is premature and raises significant ethical complications. As discussed in Section VI and Section VII below, the firm has ongoing obligations to the client with respect to the prosecution files, and asserting a lien over those files while statutory deadlines are pending could

VI. ETHICAL CONSIDERATIONS — WITHDRAWAL VS. CONTINUED REPRESENTATION A. The Core Tension The outstanding balance on this matter presents a tension that is common in patent prosecution engagements but that carries particularly acute consequences here: the firm has not been paid for more than fourteen to fifteen months on the outstanding invoices, and the total receivable is now approaching $60,000. Under ordinary circ

1. Calderwood & Harkness cannot ethically withdraw without providing OWS with clear, written notice of every pending deadline and adequate time to engage successor counsel. The twelve-application, three-jurisdiction scope of this docket, combined with the technical complexity of the underlying technology and the need for successor counsel to review extensive prosecution histories, means that a transition to new couns

2. Calderwood & Harkness must continue to monitor and report deadlines regardless of payment status. The duty to communicate impending deadlines is independent of the fee dispute and cannot be suspended or deferred pending payment. The firm's obligation to notify OWS of the March 9, 2025 A1 deadline, the April 21, 2025 B1 deadline, and all subsequent statutory deadlines persists regardless of whether the outstanding

3. Withdrawal is not recommended at this time. Taking into account the imminent statutory deadlines, the complexity of the docket, the strength and longevity of the client relationship, and the likelihood that the Project Lighthouse budget freeze may be partially lifted for critical filings — as demonstrated by Sandra Koh's October 2024 authorization of the emergency B1 extension — the undersigned does not recommend

4. If payment is not resolved by Q1 2025, the firm should reassess. Should OWS fail to authorize payment of the outstanding balance and fail to authorize budget for the critical A1 and B1 responses by early February 2025, the calculus may change. At that point, the firm should prepare a formal withdrawal notice with comprehensive deadline disclosure — including a detailed schedule of all pending deadlines, the status

VII. ADDITIONAL CONSIDERATIONS A. Lien on Work Product Under California law, Calderwood & Harkness may have a retaining lien on work product in its possession, including the incomplete A1 Office Action response draft prepared by Christy Bauer before the dormancy period. A retaining lien is a common-law right that permits an attorney to retain possession of a client's papers and documents until the attorney's fees are

VIII. SUMMARY AND RECOMMENDATIONS Based on the analysis set forth in this memorandum, the undersigned respectfully recommends the following course of action:

1. Finalize and issue the WIP invoice immediately. The $34,218.50 in unbilled work-in-progress should be converted to a formal invoice (proposed Invoice No. 2024-11-04187) and transmitted to OWS without further delay. The undersigned will prepare the invoice for your review and approval.

2. Invoice the October 2024 emergency B1 extension. A separate invoice should be issued for the emergency extension filing completed on October 18, 2024, including the $2,560 USPTO disbursement and associated attorney time, with reference to Sandra Koh's October 15, 2024 email authorization.

3. Send a formal collection letter to Marcus Whitfield. A formal written collection letter should be sent from the undersigned to Marcus Whitfield, General Counsel of OWS, escalating the $56,958.50 outstanding balance (plus the emergency extension charges) and requesting payment within thirty (30) days. The letter should be professional in tone, should emphasize the firm's continued commitment to the client relations

4. Continue deadline monitoring and client notification. The firm must continue to monitor and communicate all pending statutory deadlines through the critical March–July 2025 deadline window, regardless of payment status. This obligation is independent of the fee dispute and must not be deferred or conditioned on payment.

5. Do not pursue withdrawal at this time. For the reasons discussed in Section VI, withdrawal from the OWS engagement is not recommended at this time. The firm should reassess the withdrawal question in early February 2025 if no meaningful progress has been made on either payment of the outstanding balance or budget authorization for the critical A1 and B1 responses.

6. Prepare a comprehensive deadline warning letter. Catherine Bloom should separately prepare and transmit a comprehensive deadline warning letter to OWS — with a suggested target delivery date of December 2024 — documenting all imminent statutory deadlines, the consequences of inaction, and the actions required to preserve OWS's patent rights. This letter will serve the dual purpose of fulfilling the firm's communic

7. Coordinate collection strategy with docket reactivation. Any collection efforts should be coordinated with any forthcoming docket reactivation proposal to Veltrano and OWS. The imminent deadlines will force a decision point for OWS and its PE sponsor, and the resolution of the outstanding balance should be integrated into any discussion of budget authorization for new prosecution work. The firm should not agree to
