What is a copyright search?

A copyright search is a review of the Canadian Intellectual Property Office (CIPO) database to identify existing copyright registrations. A copyright search is often performed before filing a copyright registration, before entering into a license agreement or assignment, or as part of due diligence in a commercial transaction involving copyright-protected assets.

Why you should consider a copyright search

Verifying chain of title before a transaction. A copyright search can identify recorded copyright registrations, assignments, and licenses. Buyers, investors, licensees, and distributors often consider a copyright search as part of due diligence before committing to a transaction that relies on the seller or licensor owning the underlying copyright.

Identifying conflicts before filing a copyright registration. Before submitting a copyright registration to CIPO, a copyright search can identify whether an existing registration already claims the same or a similar title, or whether another party has recorded a claim of ownership. A copyright search does not prevent filing, but it can surface issues that may be addressed before a copyright registration is on the public record.

Supporting enforcement and infringement analysis. Where a client is considering a cease and desist letter, a DMCA takedown request, or a statement of claim for copyright infringement, a copyright search can help confirm that the complainant’s copyright registration is on the public record and can identify whether the alleged infringer has any competing registration. A copyright search can also identify recorded assignments that may affect who has standing to bring a claim.

Reducing risk when commissioning or licensing work. For businesses commissioning original works from independent contractors, agencies, developers, artists, or studios, a copyright search can help confirm that the party granting the license or assignment is actually entitled to enter the contract.

Protecting confidential information and data alongside traditional IP. Many commercial transactions involve a bundle of rights that includes copyright, trademark, trade secrets, and confidential information and data. A copyright search can form part of a broader IP diligence process that also includes a trademark search, a review of employment agreements, independent contractor agreements, and confidentiality obligations.

Relevant laws and regulations

Copyright Act, RSC 1985, c C-42. The federal statute that creates copyright in Canada, establishes the copyright registration regime administered by CIPO, and provides for the recording of assignments and licenses on the copyright register. The Copyright Act also sets out the evidentiary presumptions that flow from a registered copyright and the available remedies for infringement.

Trademarks Act, RSC 1985, c T-13. Logos, stylized text, and design elements often intersect with both copyright and trademark law. A copyright search is frequently performed alongside a trademark search where the subject matter overlaps.

Common legal issues

Absence of a registration does not mean absence of copyright. A common misunderstanding about a copyright search is that a blank result means the work is free to use. It does not. Copyright subsists automatically in original works under the Copyright Act whether or not a copyright registration exists. A copyright search shows what is on the CIPO database, but many copyrighted works in Canada are unregistered.

Search limitations on the CIPO copyright database. The CIPO copyright database is generally searchable by title of work, owner name, and registration number. It is not a full-text or content-based search, which means that works registered under a different or variant title may not surface. A copyright search can also miss relevant registrations where the owner name has changed through assignment but the register has not been updated.

Chain of title gaps not visible on the register. A copyright search may not show assignments, employment-based ownership by operation of law, moral rights waivers, or licenses that were never recorded with CIPO. A copyright search often needs to be supplemented by a contractual review of employment agreements, independent contractor agreements, and assignment documentation.

Relying on a copyright search for clearance. A copyright search does not clear a proposed use of a work in the same way that a trademark search can support a clearance opinion. A proposed use may still infringe copyright in an unregistered work, a foreign work, or a work registered under a different title. A copyright search is generally considered one input into a broader risk assessment, not a standalone clearance.

Foreign copyrights not captured. The CIPO copyright database reflects Canadian registrations only. Works protected under foreign copyright regimes, including works that benefit from reciprocal protection under international treaties, are not searchable through a Canadian copyright search. Cross-border projects often require copyright search work in other jurisdictions as well.

Frequently asked questions

Is a copyright search mandatory before filing a copyright registration? No. A copyright search is not required by CIPO and is not a prerequisite to filing a copyright registration. A copyright search is generally considered a risk-management step that can identify issues before a registration is on the public record.

How far back does the CIPO copyright database go? The CIPO copyright database is generally searchable for registrations filed from 1991 onward. Earlier records exist but may not be available through the online copyright search interface and may require alternative retrieval methods.

Can a copyright search confirm that a work is in the public domain? Not on its own. A copyright search shows registration records but does not determine whether copyright in a work has expired.

Does a copyright search show licenses and assignments? It can, where those documents have been recorded with CIPO. Not all licenses and assignments are recorded, so a copyright search often needs to be supplemented by a review of the underlying contracts held by the parties.
