New Patents. 157 



ber of inventions into their specifications ; but the practice of leav- 

 ing them to their own discretion, under the penalty of setting aside 

 their whole patent, because they have exceeded just bounds (which 

 bounds are not defined) is both unjust and impolitic. 



Since a patent for the three kingdoms, with the attorney's bill, 

 costs from four to five hundred pounds, does not that operate as a 

 tax upon different inventions with great inequality ? — The expense 

 of the patents for the three kingdoms is decidedly too high ; I think 

 that the present expense of a patent for England, would be about 

 the proper expense for a patent for the whole of the British domi- 

 nions. I mean, that in the absence of any other check to an unli- 

 mited multiplication of patents, they should not be granted too 

 cheaply. At present, while patents are to be had merely for paying 

 the fees, there must be somelimitation applied by means of the ex- 

 pense, and I think the present expense for England is a limitation 

 which is sufficient; but when to the expense of a patent for En- 

 gland, the expense of one for Scotland, and another for Ireland, is 

 added, and also an additional variable expense depending upon the 

 difficulty of the subject, the sum total is in my opinion too much 

 for mere limitation, and becomes a tax upon particular inventors, 

 who are commonly the most deserving of encouragement. The ex- 

 penses relating to the specification vary according to the nature of 

 the subject. I think the sum total to the patentee should be made 

 invariable, or nearly so.
