12 As I have mentioned, by the express terms of the 2003 Licence Agreement, Glew Technologies, as assignee from Mr Glew, purported to licence to FJPL the intellectual property rights defined in that agreement. Those rights were defined by reference to a schedule (the second schedule), which contained reference to two patents. By the time of the hearing, a further two patents had been granted in respect of fuel delivery systems which appeared to have features in common with the systems the subject of the two patents specified in the 2003 Licence Agreement. The first issue which was presented to the court by FJPL in relation to the 2003 Licence Agreement was whether Glew Technologies had good title to the intellectual property rights which it had purported to licence to FJPL and if not, whether Mr Glew was obliged, as a term of that or some separate agreement, to assign title to Glew Technologies, or, in the alternative, whether Mr Glew and Glew Technologies were estopped from denying that Glew Technologies had good title to the intellectual property rights and, in order to make good that estoppel, Mr Glew could be ordered by the court to assign title to Glew Technologies.
