Someone has filed an invalidation request for my patent. I will defend the patent invalidation application myself. Do I need to attend the oral examination in person?

For your own patent invalidation defense, it is recommended that you attend the oral hearing in person.

The oral hearing requires a targeted rebuttal based on the invalidating party’s reasons and evidence. Whether the invalidation reasons are established depends on whether the invalidating party’s basis for invalidating your patent protection scheme is reasonable. The submission to the annulment tribunal can be more targeted.
