Post grant services – Opposition/Appeal

law-40007_640If an individual or entity believes a European patent was granted incorrectly, opposition may be filed for a period of nine months following the grant.

The examination procedure is then repeated, considering arguments submitted by the opponent or opponents.

An opposition is a legal procedure having strict procedural requirements, often requiring a European patent to handle opposition proceedings.

If somebody opposes your patent and you need to defend yourself, or if you wish to file an opposition against a patent that you would like to be revoked, Patenthuis can conduct the procedure for you.

After an opposition, the losing party may appeal. We can conduct the appeal procedure as well.

For further information about opposition, please see the dedicated website maintained by Patenthuis:

Renewal Fees payments

Renewal fees need to be paid annually in Europe, both before the patent is granted and after. If a renewal fee is not paid on time, the patent may be lost irrevocably.

At Patenthuis, we can monitor and arrange the payment of renewal fees for your patents to maintain them.
