FAQs
What is a patent opposition?
A patent opposition is a legal procedure at the European Patent Office (EPO) that allows any person or company to challenge the validity of an existing granted patent. The Challenger must present evidence and arguments before a Patent Office to prove that the granted patent should not have been issued in the first place. Oppositions at the EPO are unique opportunities to challenge European-granted patents in all countries where a patent is valid.
When can I file a patent opposition?
To protect your rights, it is crucial to file a patent opposition within nine months of the grant of the patent. By doing so, you can challenge the patent's validity and potentially prevent any undeserved monopolies. Taking prompt action ensures a fair and competitive landscape for innovation.
What happens after filing a patent opposition?
Once a notice of opposition has been filed, it will be communicated to the patentee, who has four months to respond. All parties will be invited to attend an Oral Hearing before a panel of three experienced members with extensive knowledge in the field. During this crucial session, both parties will have the opportunity to present their arguments and provide supporting evidence, allowing the panel to thoroughly assess and determine the validity of the patent in question. The Oral Hearing is a significant milestone in the process, ensuring a fair and comprehensive evaluation of the case. At the oral proceedings, the patent will be either maintained as granted, revoked, or maintained in amended form.
