Your First Step: Infringement and Validity Opinions

At the outset, when acting for an intellectual property rights holder, we will help you evaluate whether a competitor has infringed your intellectual property rights. When acting for the alleged infringer, we will assess what non-infringement arguments may be made as well as determine your chances to succeed on allegations that the intellectual property rights asserted against you are invalid or non-enforceable.

With the results of the opinion in hand, we will then work with you to develop and carry out a litigation strategy and/or a plan of action for resolving the matter out of court.

The Typical Stages of a Court Proceeding


Most intellectual property litigation in Canada takes place in the Federal Court. A lawsuit is typically commenced by the plaintiff issuing a statement of claim which the defendant responds to in a statement of defence.

A defendant may also make a counterclaim containing allegations against the plaintiff in the same document as its statement of defence. The plaintiff may then reply to the statement of defence and respond to the allegations in the counterclaim. If a defence to a counterclaim is made, the defendant may also reply to the defence.


Following the close of pleadings, the lawsuit enters the discovery stage. Each party to the lawsuit conducts a search of its own documents for documents relevant to the issues in the lawsuit. A list of relevant documents, and most often copies of those documents, are then provided by the parties' lawyers to the other parties' lawyers in the lawsuit.

In intellectual property lawsuits, there is often a confidentiality order or protective order or agreement in which the parties have agreed to certain conditions regarding who can access the documents provided. In some cases, access to certain highly confidential documents is restricted to only the lawyers and independent experts for the parties.

Following the exchange of documents, oral examinations of the parties take place. If the party is a company, a representative for the company is examined by lawyers for the adverse parties. The questions and answers from the examinations are recorded in written transcripts for use at trial.


In most intellectual property cases, expert reports are prepared and exchanged following examinations for discovery. A pre-trial conference with the Court will also take place to plan for a trial.


A trial in the Federal Court is heard by a single judge without a jury. Typically, the judge does not decide the matter at the conclusion of the trial, but rather issues a written judgment and reasons several months later.

In its decision, the court will likely order the losing party to pay the successful party some portion of its legal costs. Typically, the amount is less than 25% of the party’s actual legal costs.

It usually takes at least 18 to 24 months to get to a trial in the Federal Court with a decision following some months thereafter.


The decision of the trial judge may be appealed to the Federal Court of Appeal. An appeal will be decided by a panel of three Federal Court of Appeal judges. There is no further discovery in the course of the appeal. Each party files written submissions in advance of the hearing and then makes its oral submissions at the hearing.

Appeal decisions are often issued within weeks of the appeal and sometimes the decision is given at the conclusion of the hearing with written reasons for the decision following shortly thereafter.
