Examine what, if any, patent properties you already own and what products they cover. If in doubt, ask your Patent Attorney to assist you.  

Consider whether or not you need to take steps to be able to identify the profits generated directly by these products.     

Where new products are under development or old products are being improved, you should reconsider your patenting policy. Even in areas such as the aerospace industry, where patenting is less common due to the protections of certification, patenting in the UK may become worthwhile if only to improve the tax relief.

If you have European or PCT applications pending which designate the UK, you may benefit from reconsidering a policy which does not implement the national phase in the UK.    

If you operate under a patent licence or you licence another party under a patent, review the terms of the licence. Is it in any way exclusive? If not, consider the benefits of renegotiation of the terms of the licence to be exclusive. Remember both the licensee and licensor can each claim the relief if they meet the conditions.

Any technological innovation which alleviates a new problem is likely to be patentable. It does not need to be rocket science. Something as simple as putting the blobs on the end of a hairpin has been patented. The UK IPO charges a mere GBP 230 in fees to examine and grant a patent. However, a Patent Attorney will greatly improve the chances of your application succeeding and being valid and will be able to advise you on many other matters relating to the exploitation of your patent rights.
