What every patent agent invoice must include
A patent agent invoice is more than a request for payment — it's a legal record. To stay compliant and get paid on time, make sure your invoice has these elements:
- Your full business name, address, and contact info
- A unique invoice number (e.g. PATE-001) for tracking
- Your client's name, business name and address
- Issue date and due date (Net 14 or Net 30 is standard)
- Itemized list of services with quantities and rates
- Subtotal, tax (if applicable) and total amount due
- Payment methods accepted (bank transfer, card, PayPal)
- Late fee terms if you charge them (1.5% per month is standard)
- Your tax ID — EIN for businesses, SSN for sole proprietors

Frequently asked questions
When should I send a patent agent invoice?+
Send your invoice immediately after delivering work or completing a milestone. Most patent agents use Net 14 or Net 30 payment terms.
What hourly rate should a patent agent charge?+
Typical patent agent rates range from $150/hr to $400/hr depending on experience, geography and project complexity. Mid-career patent agents average around $275/hr.
Does a patent agent invoice need a tax ID?+
If you operate as a sole proprietor in the US, you can use your SSN. Most patent agents apply for a free EIN from the IRS to keep their SSN off invoices.
Can I charge a late fee?+
Yes — most states allow 1.5% per month (~18% annualized) on unpaid invoices. Always state the late fee in writing on the invoice itself.
Is this invoice template legally binding?+
An invoice itself isn't a contract, but it's a legally enforceable record of services rendered and amount owed. Pair it with a signed contract (free via our eSign tool) for maximum protection.
