1. Introduction

ClaimCadence™ is a service of 25 Fathoms, LLC ("we," "us"). We provide drafting and research support to registered patent practitioners as supervised work product. This policy explains what we collect, how we use it, and how we protect the matter materials you send us.

2. Who This Applies To

ClaimCadence is for registered patent practitioners and the people they authorize. This policy governs your use of the site and the service.

3. Information We Collect

• Account details. Your name, firm, USPTO registration number, email, phone number, and billing information.
• Practitioner checks. When you request a free Rejection Read, we compare your registration number and name with the USPTO's public roster of registered practitioners, check whether your email domain matches the firm on the application, and may call you to confirm who you are. We keep a record of these checks and of what happens to your Read, such as when it was delivered and when a draft was opened.
• Public USPTO records. To prepare a Read or a response, we pull the application's public file and related public data from the USPTO.
• Files you upload. If an application is not in the USPTO's public data, usually because it is unpublished, we ask you to upload its file wrapper from Patent Center. We use those files only to prepare your Read.
• Business contact information. We may email practitioners and firms about the service at business addresses that appear in public USPTO records. We check those addresses with an email-verification provider before sending, and every message includes a way to unsubscribe.
• Usage data. Log data, device and browser information, and how you use the site, collected as described in Section 6.
• Matter materials. The office actions, claim sets, specifications, correspondence, and any other files you submit so we can prepare a response. These may include your client's confidential information.

4. How We Use Information

We use your information to deliver the Rejection Read and the response package you request, to communicate with you about your matters, to handle billing, to operate and secure the service, and to meet legal obligations. We prepare drafts with the help of artificial-intelligence tools, including models provided by Anthropic; that processing produces your work product only. We do not use your matter materials to train external AI models, and we do not sell them.

5. How We Handle Your Matter Materials

We treat every office action and matter file you send as confidential. We use it only to prepare the work product you requested and to support you on that matter. We do not sell it. We do not share it with third parties for their own use. We work from the public prosecution record unless you supply privileged material, and then only to serve your response. Access inside our team is limited to the people preparing your work.

6. Cookies and Analytics

We use cookies and similar technologies to run the site and understand usage. Where required, we ask for consent, and we honor recognized browser signals such as Global Privacy Control. You can control cookies through your browser settings.

7. Sharing and Subprocessors

We share information only with service providers who help us operate the service: hosting and storage, authentication, email delivery, outreach email and email verification, payment processing, and AI drafting assistance (Anthropic). Each handles information only to provide its service to us, and our AI provider account is set so your matter materials are not used to train its models. We may disclose information if required by law. We do not sell your information or your matter materials.

8. Data Retention

We retain account information for as long as your account is active and as needed to meet legal and accounting obligations. We keep a confidential record copy of the work product we prepare and of the materials you send us, including files you upload, for 10 years after we deliver the work product, and then we delete it. If you ask us to delete it sooner, we will, keeping only the billing record and a log that the work was delivered. Your own access follows a shorter schedule: a free draft reply can be downloaded for 72 hours after the email telling you it is ready, a free Rejection Read stays viewable in your account for 12 months after delivery, and matter materials are returned to you on request. We keep the billing record for each matter and de-identified lessons that do not identify you, your client, or the matter.

9. Security

We use administrative, technical, and physical safeguards designed to protect your information, including encryption in transit and at rest, access controls, and limited internal access. No system is perfectly secure. If we confirm unauthorized access to your matter materials, we will notify you within 72 hours of confirming it and will cooperate with any notice you need to give.

10. Do Not Sell or Share My Personal Information

We do not sell your personal information, and we do not share it for cross-context behavioral advertising. Where applicable law gives you a right to opt out, there is nothing to opt out of, because we do not do this.

11. Your Rights

Depending on your location, you may have the right to access, correct, delete, or port your information, and to object to certain processing. To make a request, contact privacy@claimcadence.com. We will verify and respond as required by applicable law.

12. Where We Process Data

We process matter materials in the United States. If you access the service from outside the United States, your information will be processed in the United States under this policy.

13. Children's Privacy

The service is for registered patent practitioners and is not directed to children. We do not knowingly collect personal information from anyone under 18.

14. Changes to This Policy

We may update this policy. When we do, we will change the date above and, for material changes, provide additional notice.
