He also advises clients in relation to IP strategy (including early-stage technology development) and negotiates complex and sensitive IP provisions in business-critical agreements, recently having been involved in a significant number of energy and decarbonisation projects.

Joshua is a co-author of the intellectual property chapters in 'Offshore Construction Law and Practice' (2nd edn) and 'Offshore Floating Production, Legal and Commercial Risk Management', both from Routledge. He has also been a visiting law lecturer to engineering students at UCL.
