Oppositions & appeals


Mewburn Ellis has a proven track record in successfully defending intellectual property rights for our clients and attacking third party rights that cause concern.

Oppositions & appeals

Granted patents and trade mark applications are vulnerable to challenge by competitors and our patent and trade mark attorneys are on hand to deal with such challenges.

Opposition before the UK Office and EUIPO

Our trade mark attorneys have a wealth of experience in both offensive and defensive trade mark oppositions and cancellation actions in both the UK and in the EU.

Their numerous and varied clients, including corporate clients and IP attorneys, have found their knowledge of the strict procedural requirements and their impressive adversarial skills invaluable.

Opposition before the EPO

Many of our patent attorneys are regularly involved in patent oppositions before the European Patent Office both defending granted European patents on behalf of our clients and attacking granted European patents owned by competitors.

Their skill in preparing persuasive written submissions and presenting strong, legally and technically sound arguments at oral proceedings has brought them an enviable success rate.
