Expert Evidence in IP Matters

Intellectual property disputes can involve technical questions that are difficult to assess without organised evidence. The use of a trademark, the appearance of a product and the operation of an invention raise different issues. Expert evidence is a procedural role with defined requirements. A commercial consultancy opinion should not be presented as having the same status as a report produced by an expert appointed by a court.

Define the question before the review

The starting point is the specific technical question that needs answering. Visual comparison, evidence of use and analysis of technical documents require different materials. Collecting every document without explaining its relevance can make an assessment less useful. Record the origin, date and purpose of the evidence so that the basis of any opinion can be understood and checked.

Organise supporting records

Relevant material may include application and registration records, product samples, photographs, catalogues, invoices and technical drawings. For online material, the context and capture date can be important alongside the content itself. Explain how samples were obtained and identify any gaps in the record. Missing evidence should remain visible as a limitation rather than being replaced with assumptions or a predetermined conclusion.

Clarify the professional role

Court appointment, a party’s expert opinion and general consultancy support can involve different qualification and procedural requirements. This page does not claim that a particular individual holds a court expert registration. The suitability and authority of the person undertaking a specific assignment must be checked separately.
