While studying for my undergraduate degree (integrated Master’s degree in Chemistry, MChem) at Durham University, many of my friends and contemporaries had their minds fixed on careers in law, finance, business management or government. While these all seemed like fantastic and rewarding careers, there was one thought holding me back from applying for the typical internships and graduate schemes: wouldn’t it be a shame to walk away from the science degree that I enjoyed and worked so hard for and do something else entirely?
In a chance encounter in the lab, I learned about the patent attorney profession from a friend who was also considering entering the profession. From that conversation and subsequent research, I learned the following:
Keen for a challenge, blasé about a few more exams after university, and liking everything else that I heard, I threw myself into the application process and was able to secure a position after graduation.
It will be no surprise that a typical day mostly involves being hunched over a desk in front of a computer, with not a small amount of email traffic management. While this is a drawback, I think that it would be a struggle to avoid this in most professional services roles these days. However, if you want a job in the great outdoors or to be jetting off to conferences and board rooms in far-flung places every other week, this is probably not the career for you.
Besides that, my days are fairly varied. I start the day by reviewing my reminders and any emails received overnight. The role is very deadline-driven, and attorneys are typically helped to manage their deadlines by a dedicated records assistant or team who generate reminders. I then assess what needs to be done, what can be delegated, and prioritise accordingly.
Once I know what my day has in store, I get to it. There are many discrete tasks that I might have to do, such as drafting and filing new patent applications, prosecuting existing patent applications, advising on infringement and validity of patents, and attacking and defending granted patents. While each are distinct tasks that arise at different times in the life cycle of a patent, they each involve the following skills:
In short, my day is mostly taken up with analysing and writing technical and legal documents and regular client meetings to take instructions from them and update them. There are occasional hearings at the patent office, which may require travel to Cardiff or Munich, though these are increasingly conducted by video conference. I am also quite involved with the training of our new trainee patent attorneys, so I am regularly preparing and delivering lectures, seminars and tutorials by video conference or in person in one of our 8 offices across the UK.
On top of that, there are also all of the responsibilities that come with working in most professional services roles: time recordal, budget management, billing, supervising and reviewing the work of others, and business development.
