William is a qualified UK and European patent attorney in our engineering team. He has experience working at all stages of the patent application process across a range of mechanical and electronic technologies. William focusses on understanding the business needs of his clients to ensure that IP and patents support their wider commercial strategy.

Since 2022 William has undertaken a part-time secondment with a multinational FTSE 100 company, supporting them with their growing consumer electronics business. He works closely to support the in-house patent department where he has gained extensive experience in developing IP strategies, conducting efficient invention capture and patent portfolio management. In particular, William has facilitated a value-based review of a patent portfolio of over 2000 documents by developing a deep understanding of our client’s business.

Through his secondment experience, William has developed extensive insight into the commercial, legal and technical challenges facing businesses, not often found in a private practice patent attorney.
