LinkedIn Profile

Rob O'Callaghan

Rob specialises in inventions involving signal processing; however, he has broader experience right across the fields of electronics and mechanical engineering.

In his research career, prior to becoming a patent attorney, Rob was actively involved in international standardisation through the ISO/IEC’s “MPEG” working group. This background gives him a special understanding of the relationship between intellectual property and technical standards.

Much of Rob’s time is spent drafting and prosecuting patent applications – for clients ranging from small businesses to multinational corporations. He has broad experience of patent prosecution internationally, including less common procedures such as post-grant re-examination in the USA. Rob also has an active practice in contentious work – mainly opposition proceedings at the European Patent Office.

When he qualified as a Patent Attorney, Rob was awarded the Strode Prize for the highest mark in Paper P2 (Patent Agents’ Practice) of the UK examinations.
