## When to use it

Use when a client wants a first written demand about a mark used in US commerce. Do not use it to allege unregistered trade dress unless non-functionality is in the file. Do not send it until each registration number has been read on the current USPTO record.

## How AI may be used

AI may place the mark, the registration number and the complained-of use into this letter from the file. The lawyer checks the register, the likelihood-of-confusion facts and the tone before the letter is sent.

**AI may:**

- Fill the mark, the goods or services, and the registration number from a record the lawyer has opened
- List the dates, URLs and specimens in the file under the description heading
- Compare a draft with this letter and flag any sentence that states infringement as a concluded fact

**AI must not:**

- Must not state that a court would find infringement, dilution or a false designation
- Must not invent a registration number, a class, or a USPTO search link
- Must not add a trade-dress allegation, or a demand for a stated sum of profits or damages

**The lawyer checks:**

- Each registration number and the goods or services match the current USPTO record
- The letter describes the use and the statute that may apply, and does not declare that infringement has occurred
- Any profits or damages point under § 1114(1)(b) is made only if the knowledge element is supported

## Authorities

- [15 U.S.C. § 1114(1) (registered marks)](https://www.law.cornell.edu/uscode/text/15/1114)
- [15 U.S.C. § 1125(a) (false designation of origin and false advertising)](https://www.law.cornell.edu/uscode/text/15/1125)
