Commercial & Intellectual Property

“Jason is approachable and friendly but always professional. Clearly he knows his subject but is able to communicate to non-legal professionals in a clear and concise manner. He always responds in a timely and appropriate manner… He will always endeavour to find the solution you are looking for or come up with an alternative solution that may be more appropriate.” – Finance Director, Beauty & Fitness Group (UK)


Jason is the lead Partner for commercial and intellectual property law at Converse Law, based in Cheltenham in the United Kingdom. His commercial law practice compliments his focus on intellectual property, technology, and innovation, which includes clients within the design, digital & IT, financial, manufacturing, retail, and NFT sectors.

Before joining Converse Law in 2019, Jason was Head of Legal and member of the senior leadership team for a UK software technology company, delivering B2B technology solutions within the digital retail sector throughout EMEA, APAC, and the US. He led and was responsible for the company’s global commercial and SaaS contracts strategy; established the company’s GDPR compliance team; and supported the company in its sale to a significant and leading European plc.

While at a UK Legal200 law firm, Jason was Partner in the commercial team and led the Intellectual Property Law practice. He supported business clients from a wide range of industries and sectors including research-based organisations, eminent UK learned academies, public listed companies, and government agencies. A significant part of Jason’s practice involved the assessment and protection of new technology and innovation, exploitation of intellectual property assets, and the enforcement of IP rights. He has been recognised and noted as a leading lawyer by the Legal500.

Jason holds a Master’s Degree in intellectual property law, a Bachelor’s Degree with Honours in law, and has been a practising UK lawyer since 2005.


Over the years Jason has acted for a number of UK superbrands, household names, leading businesses/retailers, as well as entreprenuers, UK start-ups,  owner-managed businesses, SMEs, and a variety of international businesses.

In addition to preparing commercial contracts and protecting intellectual property, Jason has supported clients in connection with contract disputes, passing off and infringement matters, representing them before the UK County and High Courts, the General Court (Luxembourg), the UK IPO, EU IPO, and WIPO, along with both Nominet and WIPO domain name dispute resolution panels.

What’s your approach?

As a client you are most likely looking for a combination of factors from your preferred legal counsel, including obtaining some ‘added value’. Therefore for you it is more than just simply sourcing a lawyer: you’re looking for a legal partner.

Your matter is important and requires completion in a way that works best for you. However each client works differently. In order to help me better understand your preferred approach, please identify 2 preferences from the following list that is most important to you for your particular matter:

  • to conclude the matter in a tight timeframe or prior to a looming deadline (urgency);
  • to complete the matter in a cost-effective way (low cost);
  • to pay special attention to your matter, which is particularly important and requires specific consideration (valuable).



Consider which of the following is critical to enable the successful conclusion of your particular matter or project:

  1. Efficiency: the need for someone who is able to deal with challenging projects without causing further complication or headache for you.
  2. Approachability: the need for a personal touch and being able to get on with you and your colleagues, who has an understanding of your business, your challenges, as well as opportunities within your sector.
  3. Availability: needing someone who is always around when you want them even after your matter has concluded.
  4. Support: your desire to receive clear, tangible, and pragmatic options to compliment your commercial outlook, that in turn can be effectively communicated to your team enabling a definitive and actionable plan, or that simply provides you with the solution you want.
  5. Experience: to have someone who has worked in your industry or sector who has successfully concluded the particular matter you need support for.
  6. Urgency: not only recognising that it is your timelines that are important and working with you to achieve those deadlines, but being up-to-date, pro-active, and keeping an eye on the horizon for you.
  7. QWAN: you may have an idea of some other quality you are specifically looking for…
