The licence cannot be assigned, but it can be determined 
by the Board of Trade if in the opinion of the Board of Trade : 
(a) The Licensee has failed to use the licence so as to satisfy 
the reasonable requirements of the public with regard 
to the patented invention ; or 
(b) The Licensee has charged unreasonable or excessive 
prices for articles made under the licence ; or 
(c) Circumstances have arisen which make it just and 
equitable that the licence should be determined in 
whole or part. 
Manufacturers’ Outlay. 
If licences were to be generally granted to any and 
every applicant, no encouragement whatever would be given 
to manufacturers to introduce the invention by putting down 
plant or taking unusual and expensive steps to make the 
article known, and therefore the continuity of the enjoyment 
of the licence is a condition that will undoubtedly be taken 
into account by the Board of Trade should the patentee 
at any time after the war apply to have the licence 
cancelled on the ground that the terms given have not been 
equitable or that material facts were not presented to the 
Board of Trade when such licence was granted. Unless a 
manufacturer is assured that it will be worth his while to 
spend money in preparing for the manufacture of a patented 
article and possibly go to great expense in the matter of tools 
and plant, or in preparing catalogues and lists of such for 
securing publicity, no benefit will result to British industry. 
On the other hand, all these facts in the matter of expense, 
outlay and convenience will have to be taken into account if 
the licence is ever subsequently interfered with, so that the 
manufacturer need be under no real apprehension as to any 
vexatious or malicious interference that is likely to arise with 
his enjoyment of the licence when once that has been granted, 
although it w’ould be well for him to remember that such 
licence has been granted primarily for the benefit of the 
British public and the requirements of British industries.
