What an Intellectual Property Non-Infringement Opinion Should Address

A legal non-infringement opinion is an analysis of specific rights and facts, not merely a certificate announcing that an item is lawful.

Define the protected right

Identify the relevant registration, patent, copyrighted work or trademark and the legal scope of the protection being asserted. The legal approach differs depending on whether the allegation involves patent claims, ornamental appearance, source identification or copying.

Compare the accused material accurately

For patents, the comparison may require claim limitations or design drawings; trademark questions may involve marketplace use and confusion; copyright matters can involve ownership, substantial copying or licensed uses. Explain the evidence that supports and weakens each conclusion.

State limitations and recommended action

The opinion should avoid unsupported absolutes, identify uncertainties and distinguish a legal assessment from a guarantee of platform or court action. Supporting exhibits, a clear factual description and appropriate recipient-specific correspondence make the work more useful.

Additional considerations

A responsible opinion identifies its purpose, date, relevant jurisdiction, documents reviewed and material factual assumptions. It should distinguish verified product evidence from information supplied by a client or supplier and indicate what was outside the review.

Depending on the asserted right, an opinion may analyze patent claims or drawings, trademark use and confusion, copyright ownership or license scope. It should also explain limitations and avoid suggesting that a law-firm letter binds Amazon, a rights owner or a court.
