The Burden of Proof

Once a patent has been registered, it automatically enjoys the presumption of validity and registrability. Therefore, once a cancellation petition has been filed, the burden of proof is on the party requesting the patents’ cancellation.

The Process of Cancellation

Both the District Courts of Israel and the Patent Registrar hold the authority to cancel the registration of a patent due to lacks prerequisites for protection as described in the Patent Act (Section 74-75 of the Patent Act).

The process of cancellation is quite similar to a “mini-trial”:

In order to file a cancellation, one must first file a “Notice of cancellation” The patent owner will respond to this notice (“Counter-Statement”). Failure to do so will result in the patent’s dismissal.

Each party will then need to present its supporting evidence (affidavits, consumer testimonies, surveys, expert opinions, advertisements, and so forth). Both parties and witnesses will then testify and will probably be cross-examined. Each party will present their written summations and finally, the Registrar or the Court will decide whether or not to accept the cancellation.

The Validity of the Cancellation Order

The cancellation order will come into effect thirty days after the end of the period for filing an appeal; But if an appeal has been filed, the court may delay its entry into effect or condition its entry into effect.
