If you are considering applying for a patent, you are necessarily considering how to create a commercially valuable property, possibly an asset of great value. A few patents have been worth hundreds of millions of dollars. It may be the foundation of your business.
A patent is a complex legal document. It is subject to challenges as to its validity by anyone, notably your business competitors. If it is not formulated carefully and with a thorough understanding of the relevant laws, it will be much more vulnerable than otherwise.
It is the thorough legal training, following graduation in a scientific or engineering discipline, as well as on-going CPD which enables a qualified Patent Attorney to get it right first time, saving the client unnecessary delays or expense.
