BIM45951 - Specific deductions: patents & royalties: costs of obtaining or extending patent rights

There is general guidance as to the meaning of a patent and the legal background at CA75000 onwards. This chapter does not seek to duplicate the guidance given there.

For companies holding intangible assets, such as patent rights, which they created or acquired from an unrelated party after 31 March 2002, the guidance in the CA manual is no longer current, and instead you should consult the CIRD manual for details of the taxation treatment of expenditure and receipts relating to these assets. (For more information about the new CT regime for intangible assets see BIM35500 onwards.) The guidance in the CA manual is still current for assets held by individuals and partnerships and for assets acquired by companies before 1 April 2002.

In general, as regards the allowability of fees and expenses incurred in obtaining the grant of, or an extension of the term of, a patent, see CA75300. It should be noted that ICTA88/S83 also allows a deduction in respect of costs where a patent application has been refused or abandoned, so long as the application was made for the purposes of the trade.

As regards revenue expenses incurred in devising a patent, see CA75310, and for companies consider also the possible application of research and development reliefs which take precedence if relevant (CIRD10500), or the applicability of the intangible asset regime BIM35500 onwards. For capital expenses, you again need to consider whether intangible asset treatment is appropriate for companies, and bear in mind the possible availability of research and development allowances (CA60000 onwards).
