If you ask Stephen Mohun how he got into intellectual property, he’ll be the first to admit it wasn’t a lifelong calling. “I’m ashamed to say it was nothing more than a job advert,” he confesses with a laugh. But sometimes the best careers start with curiosity—and in Steve’s case, it sparked a lifelong passion for helping innovators protect and leverage their ideas.
Now the founder of Mohun Aldridge Sykes, Steve has spent nearly four decades advising clients on patents and trademarks, building a reputation for practical, strategic, and empathetic support—especially for those in the manufacturing and engineering sectors. His client base ranges from ambitious start-ups to global corporates, and his advice is always grounded in commercial reality.
“We always start with their bigger goals and work back from there. That’s how we build a real IP strategy—not just a filing plan.”
From Yorkshire Roots to Global Reach
Steve began his career at a local Yorkshire firm and worked his way through larger practices, eventually becoming a partner before founding the firm that became Mohun Aldridge Sykes. Launching his own boutique firm wasn’t just a career pivot—it was a chance to do things his way.
What sets Mohun Aldridge Sykes apart? It’s the depth of relationships. “We genuinely get to know our clients. We’re not just experts on the other end of the phone—we’re part of their strategic team.”
Intellectual Rigor, Commercial Focus
With a background in physics and a mind wired for problem-solving, it’s no surprise Steve is drawn to patent work. “I like understanding how things work,” he says. “Manufacturing clients, especially those in second or third-generation family businesses, are some of my favourites. They’re quietly innovating in ways they don’t always recognise.”
And that’s where Steve sees one of his biggest responsibilities: helping clients see the true value in their ideas. “Too many engineers dismiss their own work as ‘obvious.’ It’s our job to show them that what they’ve created might be valuable—and worthy of protection.”
Helping Clients Navigate Complexity
One of Steve’s great strengths is translating legal complexity into clear, actionable advice. “You have to put yourself in the client’s shoes. Legal jargon just puts up barriers. Our goal is to empower them.”
He’s particularly mindful of budget constraints for early-stage businesses. “The biggest mistake they make is spending too much too soon on the wrong things. We help them build a flexible, strategic IP plan that grows with them.”
A Trusted Partner in Innovation
Steve describes the ideal client relationship as one built on mutual trust. “They need to trust me to give honest, clear advice. And I need to trust that they’re telling me what’s really going on in the business.”
That trust has paid off—whether it’s guiding a manufacturing client into a leadership position through carefully managed IP, or helping a tech start-up secure patents in a notoriously difficult field. “That one surprised even me,” he says, recalling a breakthrough. “But we got there, and today those patents are their most valuable asset.”
Supporting the Next Generation
Mentorship matters to Steve. Mohun Aldridge Sykes welcomes interns and work experience students, giving them a real taste of the profession. “We’ve all had good careers in this field,” he says. “It’s important to put a bit back in.”
Staying Agile in a Changing Landscape
As AI and tech continue to reshape the IP world, Steve stays ahead by listening. “You’ve got to talk to people—clients, colleagues, other professionals—and keep your ear to the ground. The moment you stop adapting, you fall behind.”
His golden rule for entrepreneurs? Talk to your IP attorney early and often. “There’s no such thing as too early, but there’s definitely too late.”
Beyond the Office
When Steve isn’t advising clients or mentoring the next generation, you might find him on stage. A proud member of the Batley Gilbert and Sullivan Society, Steve regularly takes on leading roles—with his recent turn as the captain in H.M.S. Pinafore being a personal highlight. “Both my kids were on stage with me,” he smiles. “There’s nothing better than that.”

From diagnostics to cannabis-based therapeutics, Sophie Topham’s career in biotech patent law has been anything but predictable. A Senior Associate in the biotechnology team at Marks & Clerk, Sophie’s calm, analytical approach is matched by a refreshing curiosity—qualities that have made her an invaluable asset to clients and colleagues alike. We caught up with her to hear about her work, career path, and the rare case that led to one of her most widely read articles.
From Immunology to Innovation
Sophie’s current docket spans a broad range of biotechnology innovations. While she regularly works with immunology-based diagnostics and oncology-related inventions (including peptide vaccines and tools for identifying oncogenic mutations), her work is as diverse as the biotech field itself.
“Over the last few years, I’ve also worked in the cannabis field, particularly with extracts and synthetic cannabinoids for medical uses,” she explains. “And more recently, I’ve seen an increase in devices—some that resemble ELISAs on a chip, others that use antibodies in more novel ways.”
Despite the increasing overlap between biotech and AI, Sophie admits she still has a soft spot for what she calls “pure biology.” “As a biologist by training, those are the ones I find the most intuitive to work with.”
A Curious Case of Prior Art
In 2024, Sophie penned an article about an unusual and educational experience: having a client’s own clinical trial proposal cited as prior art against their European patent. It was the first time she’d encountered such a scenario—and it proved just as useful for the IP community as it did for her personally.
“Opponents in an EPO opposition cited the client’s trial proposal, which we hadn’t seen before due to a team change on the client’s side,” she recalls. “I had to dig into the case law to understand how such documents are interpreted, especially regarding whether the invention was truly disclosed.”
The case raised interesting questions around whether and how other documents—such as scientific publications—can be used to interpret clinical trial proposals, and how that squares with the EPO’s guidelines.
Understanding the Unusual
Sophie is quick to point out that having clinical trial proposals cited as prior art is still uncommon. “Patent applications in biotech typically don’t require clinical data to be granted. In vitro data is often sufficient for meeting plausibility requirements, so most companies file before trials begin,” she says.
Still, her experience highlighted how easy it is for assumptions to trip up even the most diligent teams. “We’ve seen clients express genuine surprise that their own publications can be cited against them—especially in Europe where there’s no grace period.”
The Route Not Taken
Like many in the IP profession, Sophie’s path wasn’t a straight line. “I originally wanted to be an airline pilot,” she laughs. “But when airlines stopped sponsoring training, the cost became unrealistic. Then I remembered a careers talk we had at university about being a patent attorney. I looked into it, and here I am.”
With a background in biological natural sciences from Cambridge, Sophie’s analytical mindset found a perfect home in IP law. She’s since seen applications through from drafting to grant, oppositions, and even appeals.
“Seeing something I’ve written be granted—and knowing I helped a startup gain recognition through their patent—those are the highlights,” she says.
Life Outside the Office
When she’s not deep in a patent claim, Sophie is rarely still. “I always try to move—walk, cycle, yoga, strength training. Even when working from home, I’ll build exercise into my day.” She’s part of a cycling club and makes time for a proper lunch break most days—usually with some kind of movement.
Evenings are more relaxed: cooking from scratch, reading anything from spy novels to translated Japanese fiction, and planning her next getaway. This summer, she’ll finally fulfil a childhood dream—horse riding along the beaches of Morocco with her twin sister.
If Only There Were More Hours…
When asked which fictional invention she’d most like to patent, Sophie doesn’t hesitate: “Hermione Granger’s Time-Turner. I’d love more hours in the day. If I knew how it worked, I’d make one!”
With her blend of sharp legal insight and grounded, genuine enthusiasm for the science behind the patents, Sophie brings a distinct human touch to biotech IP. Whether she’s tackling tricky prior art or galloping down a Moroccan beach, she’s doing it with purpose and passion.

From ballroom dancing and ten-pin bowling to guiding cutting-edge startups through the complexities of intellectual property, Andrew Flaxman has certainly had a diverse journey. Today, as a partner at Bristol-based IP firm Stevens Hewlett & Perkins (SH&P), Andrew is a passionate advocate for startups and a specialist in software, computing, and AI-related patents.
The Path to Patents
Andrew didn’t set out to become a patent attorney. In fact, it wasn’t until the final week of university that he picked up a leaflet that introduced him to the profession. With a love of physics, a knack for language, and a curiosity about the law, the role seemed like the perfect fit. He began his career in London before making the move to Bristol, eventually rising to partner level, and joining SH&P earlier this year.
A Day in the Life (Is Never the Same)
“There’s no typical day,” Andrew says. “I might be dealing with emails, drafting patents, speaking to clients, attending partner meetings, or at a conference. Every day brings something new.”
That dynamic workday is part of what makes the job so compelling—especially for someone who thrives on innovation and the unknown.
Championing Startups
Andrew’s enthusiasm shines when it comes to supporting early-stage ventures. He works closely with the SetSquared Bristol community and is especially proud of SH&P’s initiative Pitch and Protect, which awarded £10,000 in IP support to a start-up to help them get their first patent on file.
“Startups are looking for advisors who genuinely want to help,” he says. “We’re flexible and hands-on—being part of a firm that can adapt quickly is a real advantage.”
Debunking IP Myths
One of the most common misconceptions Andrew encounters? “Startups often think there’s no point in filing patents because they can’t afford to enforce them,” he explains. “But having IP can deter infringement and is a valuable business asset. It’s normally better to have rights than to have none at all.”
He also frequently hears from clients in computing and software who wrongly believe their ideas can’t be patented. “It’s a grey area, but certainly not impossible. I spend about 80% of my time working in this space. If in doubt, just have a conversation with a patent attorney.”
IP Trends and Tech Frontiers
Andrew is especially excited about the potential in robotics and automated systems—particularly when combined with AI.
“AI is already being used to help diagnose medical conditions, but we’re not far from seeing robotic surgery controlled by AI, even without a human surgeon. It’s incredible—and IP plays a crucial role in protecting that innovation.”
He’s also watching how generative AI is shaking up the IP profession itself. While some tools can assist with tasks like drafting, Andrew believes the nuance of legal language and strategic thinking still firmly requires a human touch.
Advice to Aspiring IP Professionals
“You need a strong technical foundation, but also great communication skills and an eye for detail,” he says. “So much of our work comes down to how we use words and what they mean.”
Keeping Skills Sharp
Andrew stays current the same way many of us do: reading articles, attending seminars, and yes—occasionally checking Wikipedia. “We learn a lot from our clients too,” he adds. “Conversations with inventors are often the best education.”
The Reward? Seeing Clients Succeed
“The most fulfilling part of my job is helping startups on their journey—from first filing to commercial success. You feel like part of the team, and their wins feel like your own.”
Fun Fact: From the Dance Floor to the Finish Line
Not many patent attorneys can say they were once a ballroom dancing champion, but Andrew can. Taught by his mother, he won several competitions as a child before trading dance shoes for rugby boots. He later became a ten-pin bowling champ, and today, he’s an Ironman triathlete who completed Ironman Wales and is training for his next race in Leeds.
If He Could Invent Anything…
“A time machine,” Andrew says without hesitation. “Not to go to the future, but to visit key moments in history—just to see what life was really like.”
