Patent Oppositions

Our team blends legal expertise with commercial know-how to ensure that the oppositions match your business needs

A successful opposition requires a unique set of skills.  In addition to a strong understanding of the technical and legal aspects of a case, attorneys must convey complex arguments clearly and concisely in both written and oral form.  Our experienced attorneys combine these skills with a strong commercial understanding developed over many years working with multi-national clients across all sectors.

Whether the opposition is part of a larger litigation strategy or simply filed to keep development options open, our sector specialised teams provide tailored oppositions that address the specific needs of our clients.   We understand that the commercial factors driving a decision to oppose a patent are often as important as the arguments upon which it is based.

In cases of high importance we work closely with our clients throughout the opposition process to ensure that their strategic goal is reached.  At the other end of the spectrum,  our wealth of experience enables us to provide “off the shelf” solutions that offer quality oppositions without undue burden to the client.

Whatever the needs and expectations, we provide a variety of costing structures that balance the legal and scientific aspects of a case with its commercial importance.

Our performance in opposition proceedings, representing both patentee and opponent, is reflected in our growth and continued success.

Over the past 5 years our opposition practice has more than doubled as clients have benefited from our blend of legal and commercial expertise.  Despite this rapid expansion, we have maintained an exceptional rate of success, with Reddie & Grose consistently outperforming the industry average.

Over 50% of the cases in which Reddie & Grose acted for the opponent have led to the patent being revoked, compared to the industry average of just 29%.

Central to our success is recognising the importance of high-quality training.  We introduce our next generation of opposition attorneys to contentious work at an early stage and use mock hearings to help them develop their adversarial skills.  Complementing this organic growth, a number of our opposition team come from in-house roles, bringing extensive experience in managing litigation; settlements and oppositions.

Reddie & Grose’s oppositions practice has attorneys based in our London, Cambridge & Munich offices led by: Will Ponder and Paul Loustalan in the Advanced Engineering, Manufacturing and Materials sector; Robin Ellis and Phil Bates in the Biotechnology, Chemistry and Pharmaceuticals sector; and Pete Sadler and Nick Reeve in the Electronic & Electrical Engineering and Software sector.
