Intellectual property is central to global trade but IP laws, such as grace periods, are not yet harmonised around the world. So when the Government announced its intention to join a huge Pacific Rim trade bloc in February 2021, there were concerns about a perceived conflict with the UK's membership of the European Patent Office. Fast forward to July this year and the Government was thanking us for helping its negotiators to achieve a derogation of the patent grace period provision in accession to the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP). Lee is joined by his Deputy, Neil Lampert, and Claudia Mulholland and Dan Lenton, from political consultants H/Advisors Cicero, to discuss the intensive campaign they mounted together in the UK Parliament and in CPTPP countries to help the government protect the UK's EPO membership.
