From Filing to Enforcement: Greg Corcoran’s Approach to Smart IP Management

Meet the IP Professional: Greg Corcoran – Strategic IP with a View to the Future/Investment

Greg Corcoran founded his own practice, Greg Corcoran IP, recently in March 2025 to use his substantial commercial experience, with a clear and thoughtful philosophy: patents are business tools. When developed strategically, they can be used to mitigate risk, unlock commercial opportunity, and give clients the commercial leverage they need to thrive in an increasingly competitive world.

Greg is a European and UK Patent Attorney, UPC Representative and former in-house counsel at one of Europe’s leading technology companies. Today, he works directly with clients to support strategic portfolio development and improvement. His practice is rooted in practical experience and built on a foundation of collaboration, commercial insight, and a deep understanding of the full patent lifecycle.

A Pathway to Patents

Greg’s journey into IP law began with a desire to combine a technical background with meaningful client relationships. After early exposure to both scientific research and legal practice, he studied physics at university with the clear intention of training as a solicitor specialising in intellectual property. That plan paid off. He trained at Taylor Joynson Garrett (now Taylor Wessing) where his first experience of patent practice was revocation proceedings before the English High Court.

Greg retrained as a patent attorney in the midst of the dot-com crash in the London office of a national patent attorney firm. Through his training he sought out a more commercially focused role where prosecution decisions were made in context of business objectives. At qualification he realised his goal of securing an in-house role, managing large patent portfolios and providing clearance advice in the context of the company’s business landscape. 

Over his seventeen years in-house he worked closely with fellow in-house patent professionals, external counsel, and the company’s engineers – many of whom were the inventors of the patents in the portfolio. Ultimately, he worked with people across the entire business from product architects, colleagues in marketing, and members of the Board. Working as part of a team he needed to ensure  that patent claims, for example, aligned to the chosen IP strategy to realise-the business’ real- commercial goals.

“A patent should be more than just a description of a technical solution to a technical problem – it should be prepared so it can have claims relevant for its possible application and commercial leverage in mind.”

A Bridging Practice

At the heart of Greg’s practice is a distinctive approach that brings together three crucial elements: effective drafting, practical in-house experience, and a clear understanding of its strategic use of patents for example in litigation strategy. These pillars have influenced the preparation of the program for the CIPA Congress 2025 which is themed around the intersection of IP and AI and which Greg is chairing this week. He notes that, with the support of CIPA’s current President, Bobby Mukherjee – a leading in-house practitioner – he encouraged each panel session to have an in-house speaker. The program includes a very practical patent drafting session and a UK and UPC judiciary panel session. 

“To secure granted claims which a client can leverage to acquire the commercial value they seek, it is crucial to appreciate how your claims would work before a court, even before you put pen to paper and start drafting.”

Through his practice, Greg aims to help clients prepare more robust patents, that do not merely capture the invention which the inventor thinks has been invented, but are also prepared with how the patent may be applied commercially in mind – which may include enforcement. While his business is relatively new, the services which he offers are informed by years of experience both in-house and in private practice. He is actively building a client base that can benefit from this integrated approach.

“Drafting with foresight, advising the business to navigate third party patent landscapes, knowing how in-house teams work, and keeping one eye on how the patent could be used, even in the courtroom – these are the skills which I seek to bring together for my clients.”

Portfolio Improvement: An Underused Commercial Tool?

Greg is also advising and helping clients to improve existing portfolios – an area he spoke on at the LES Pan-European Conference 2025 in September. He will lead a further round table discussion during the CTC Winter Intellectual Property Conference in London in early November.

Portfolio improvement enables clients to achieve more value from their existing assets in the context of the patent landscape of their chosen markets. He works with clients identifying their filings that have potential to offer useful leverage and optimising claim scope in context of competitor positions. This means that he needs to learn about third party patent portfolios, and the client’s markets, not just the client’s own assets. Investment in a portfolio is also an investment in knowledge of the context of the client’s assets. With more knowledge, the more effectively, efficiently and deftly the patents in a patent portfolio may be used. Enhancement of portfolios take time and draws on experience and a strategic approach to IP. Portfolio improvement, he says, can be far more than mitigating the risk of litigation. Even if litigation mitigation is not a primary goal it is a valuable added benefit. A third party may hesitate or wait before using court proceedings, or even seek solely to negotiate, if a target business has invested in its IP position to develop an appropriate patent portfolio.  Investment in IP can help mitigate significant costs.

“Whether you’re seeking investment, looking to license out technology, or wanting otherwise to negotiate with a third party, an improved portfolio can be a benefit to your position. A well-developed portfolio informs a third party that you’re prepared with a strategy in mind.”

This proactive approach is particularly relevant in today’s global IP landscape, where pressure on IP budgets meets rising commercial expectations. Use of older filings may serve to achieve patents which can be used to apply leverage against third parties faster and more effectively than fresh filings. Under cost pressures and good timing, improvement work can be targeted, focused and limited.

The Benefits of Litigation Mitigation

Even though clients prefer to avoid talking about litigation, it has to be considered as a part of commercial strategy according to Greg. The positive reception to the UPC since it started in 2023, makes portfolio improvement to mitigate litigation risk even more important and valuable. As we are hearing from leading US practitioners such as David Kappos, an ex-UPTO Director, the UPC is changing the global dominance of the US courts because it is faster, cheaper, and more predictable in its processes and it is also more willing to grant injunctions. Commercial leaders are now describing how these characteristics, especially in view of the size of the UPC’s jurisdiction over eighteen contracting states, often lead to settlement. The risk of a negative decision leading to an injunction can create a commercial predicament for the parties. Information the UPC suggests that the chance of a settlement, in practice, is high.  

The reach of the UPC has implications for businesses of all sizes throughout the European market, including SMEs and not just global players. Before the UPC started, a business could rely on the fractured mosaic of different European jurisdictions that would limit the impact of a patent suit usually to one jurisdiction. Those days are numbered if they are not already over. Recent cases of the UPC (and even the German courts) are taking a ‘long-arm approach’ to jurisdictions under special conditions. The enforcement of patents in non-UPC states, such as Spain, or not of the EU, such as the UK, using long-arm jurisdiction, means the reach of the UPC is far further than initially expected. 

All business would be advised to invest in their patent position in a prudent manner as part of good business administration. Investment consequently mitigates litigation risk. Traditionally legal fees spent for a litigation are considered as costs that are incurred only when the litigation is under way and thus as a last resort. Funds are spent very quickly following quickly made decisions. Proceedings at the UPC run too fast using this approach, demanding too many resources for a defendant to prepare an adequate defence and respond by preparing and filing its own countersuit. The alternative is to incur some of these costs in advance carefully and strategically over a period of time -such a spending strategy would be an investment. Businesses with an adequate budget could make a long-term investment by starting preparation and mitigation long in advance; yet meaningful results can be achieved with a targeted approach on a limited budget. Yet, as Greg mentioned earlier, such preparations would also improve a patent portfolio and a business’s IP position for the other purposes for example to realise new commercial opportunities.

“Litigation as a business strategy is, after all, a last resort.” 

How Greg can Help: Practical, Independent, and In-House-Informed

One of the defining features of Greg’s offering is flexibility. His business’s offering includes services that are designed to plug into existing teams. He offers support to companies which may not have the resources for a full in-house function but still need senior-level strategic input. He offers assistance and advice in the development and implementation of a portfolio strategy, in helping align patent filings with business objectives, and flagging and assisting mitigation of litigation risks.

His experience also allows him to complement rather than compete with other attorneys, bringing an in-house angle and offering a resource to draw on. For example, providing a litigation-informed perspective to drafting and prosecution decisions and offering second opinions that improve the value of a portfolio without escalating cost.

“Predicting which patents of a portfolio will be challenged is a fool’s game; it’s more prudent and cheaper to prepare some of the patents so more of them hold up to scrutiny. I heard a repeating message when I spoke to litigation counsel across Europe in the months before I set up my practice: when their clients present them with their best patents, often only a very small proportion survive scrutiny. Counsel has to use the best patents their clients have – but does it have to be that way, especially now, when so much more can be at stake in Europe?”

Greg also understands the realities of international portfolio management and improvement. Having managed a global portfolio including the US, Europe, and Asia he appreciates the cultural challenges that such work may bring, and the nuances in local practice through engendering long durable relationships with local counsel. He helps clients navigate through such differences that are essential to manage effective communication with external counsel and manage the global IP assets of the client effectively.

A Photographer’s Eye for Detail

Outside the world of patents, Greg is a keen landscape photographer. His brand image is a striking photograph of Belgium’s famous bluebell wood, the Hallerbos. It reflects his international focus and his approach to IP: considered, layered, and aware of how small details contribute to the bigger picture and conversely how the big picture is dependent on the detail within it.

“An image is a whole, but it’s the sum of its parts and the parts make the whole. It’s  just like a sound patent portfolio.”

A Favourite Walk?

The Gower Peninsula in Wales – a mix of clifftop paths leading to green rolling countryside, overlooking sheep dotted salt-marshes and empty expansive beaches, through bluebell woods and winding rugged windswept coastal trails. It’s an appropriate metaphor for a career spent exploring new ground while keeping a careful eye on the landscape.
