Invoice templates for intellectual property consultants billing businesses and inventors for trademark, patent, and IP strategy services.
An intellectual property consultant invoice is issued by an IP advisor, trade mark attorney, patent agent, or IP strategy specialist to businesses, startups, or individuals for advice and services related to the protection, management, and commercialisation of intellectual property rights. IP consultants who are Chartered Trade Mark Attorneys or Registered Patent Attorneys are regulated by IPReg. Non-regulated IP consultants may advise on strategy, licensing, and commercialisation without performing reserved legal activities such as prosecuting trade mark or patent applications before the IPO, which requires a registered attorney. Common engagements include IP audits, freedom-to-operate analyses, trade mark searches and application management, patent drafting and prosecution support, licensing negotiation, IP due diligence for transactions, and design right protection strategies. The invoice must reflect whether charges are for the consultant's own professional time or include IPO official fees and foreign filing costs as disbursements.
| Service | Typical Rate | Unit |
|---|---|---|
| Trade mark search (UK) | 350 | mark |
| UK trade mark application (professional fee) | 500 | application |
| IPO trade mark application fee (disbursement) | 170 | application |
| IP audit | 1800 | project |
| Freedom-to-operate analysis | 2500 | project |
| Licensing agreement review | 200 | hour |
IP consultants should clearly separate their professional fee from IPO official fees and any foreign filing costs. These are distinct charges and clients are entitled to know exactly what they are paying for and to whom fees ultimately flow. For trade mark portfolio management clients, a monthly statement format works well: listing all activities across all marks in the portfolio, any official fees paid on the client's behalf, and the professional time charged. This gives brand teams and in-house counsel a clear overview of portfolio costs. For transactional work such as IP due diligence for an M&A deal, invoice against milestones: initial report, supplementary queries response, and final sign-off. Agree a fixed fee where scope is clear, or a capped time-and-materials arrangement where the scope may expand. For patent prosecution work involving foreign filing, costs can be substantial. Provide clients with a cost estimate before instructing foreign attorneys and invoice for disbursements promptly after they are incurred to avoid carrying large creditor balances on client behalf.
