Patents are not just legal tools; they’re a business strategy. Whether you’re developing new cell lines, innovative bioreactors, or optimised growth media, patents help secure your place in the future of cultivated meat.
What You Can Patent in Cultivated Meat
Understanding which parts of your cultivated meat technology can be patented is essential for building a strong intellectual property foundation. Patents can safeguard innovations across various aspects of cultivated meat production, each offering unique opportunities to strengthen your startup’s position in the market.
Cell and Tissue Growth Methods
Advancements in cell and tissue growth techniques are among the most sought-after areas for patents in cultivated meat. Processes that improve how stem cells are cultured and expanded, especially if they bring greater efficiency or introduce novel approaches, are highly valuable[1]. Patents can also cover methods for differentiating stem cells into myocytes and adipocytes, which play a critical role in shaping the texture and flavour of the final product. Innovations that speed up differentiation, enhance the efficiency of cell culture, or increase the success rate of precursor cell differentiation can become significant assets for your company[1].
The scope of protection isn’t limited to basic cell culture. Key elements like process steps, specific culture media compositions, supplemental growth factors, and unique culture conditions can all be patented. Additionally, methods tailored for culturing cells from specific livestock species, such as chicken, beef, or pork, can provide exclusive rights that set your approach apart[1].
Patents can also extend to innovations in creating marbled textures, distributing fat more effectively, or improving nutritional profiles. Furthermore, your cell lines themselves can be protected. Techniques for generating multipotent progenitor cells from livestock somatic cells, methods for immortalising precursor cells, and the resulting cell lines can all qualify for patent protection[1].
Bioreactor Equipment and Processes
Bioreactor technology is another critical area for patent opportunities, especially as the industry scales toward commercial production. Innovations in systems that enable large-scale production and devices that automate the monitoring and control of cell culture conditions are excellent candidates for patent applications[4].
Bioreactor patents often focus on solving scalability challenges. For example, large food companies are particularly interested in designs that ensure sufficient agitation to minimise gradients in nutrients, pH, dissolved oxygen, and waste, while also reducing shear stress on cells. Continuous culture capabilities are another key area of interest[1]. Additionally, patents can cover methods for harvesting and processing cultivated meat to meet both safety and quality standards[4].
A notable example is Mirai International AG, which filed a patent in August 2022 for a bioreactor method tailored to cultivated meat production. Their approach involves extruding paste through specialised plates to create elongated structures, illustrating how specific technical solutions can secure patent protection[7].
Customised bioreactor technologies also present valuable patent opportunities. These often address challenges such as food-grade operations, process intensification, and novel reactor geometries designed specifically for cultivated meat production[8].
Growth Media and Nutrient Solutions
Proprietary growth media formulations are another area ripe for patent protection, particularly as growth media accounts for about 80% of production costs in cultivated meat[9]. Innovations in both the processes and compositions that optimise cell differentiation while lowering costs can be highly valuable[4]. Companies that develop formulations enabling more efficient conversion of nutrients into cellular biomass often gain significant attention from major food industry players[1].
Animal serum-replacement formulations are especially promising for patents. These include formulations using recombinantly produced growth factors or those containing minimal animal-derived ingredients, appealing to businesses aiming for large-scale production[1]. Some cultivated meat companies have already reported media costs below £1 per litre, showcasing the potential for dramatic cost reductions[3].
Small molecules that mimic growth factors also offer strong patent opportunities. These molecules improve both cost efficiency and stability, addressing two critical challenges at once: reducing production expenses and ensuring reliable manufacturing[1]. Lastly, species-specific media optimisations - whether for chicken, beef, fish, or even more exotic proteins - can secure targeted patent protection, appealing to companies focused on specific market niches[1].
How to File Patents in the UK
If you've developed an innovation in cultivated meat, filing a patent through the UK Intellectual Property Office (IPO) is a key step to protect your work. Patents granted in the UK offer protection for up to 20 years from the filing date, as long as you keep up with the annual renewal fees [11].
Before You File
Before submitting your patent application, make sure your invention meets three critical criteria: it must be new, involve an inventive step, and be suitable for industrial application. Keep your invention confidential during this process and conduct a thorough patent search to refine your idea and identify any additional features that could be patented.
Your application should include a detailed and accurate description of your invention, covering protocols, conditions, formulations, and drawings. This level of detail ensures someone skilled in the field could replicate your invention. Pay close attention to the claims section, as it defines the scope of your patent rights [11].
Once you're ready, choose the filing route that aligns with your business goals.
UK, European, and International Filing Options
Startups in the UK have multiple filing options depending on their market focus and budget:
- UK National Patents: These cover only the United Kingdom and are often the fastest and most affordable choice. UK patents are usually granted within 1–4 years and do not include an opposition period after they are granted [14].
- European Patents: If you need broader protection, you can apply through the European Patent Office (EPO). With this route, your patent can be validated in up to 39 Member States. However, this process involves stricter examination standards and higher excess claims fees - €265 per claim beyond 15 claims, compared to £20 per claim beyond 25 claims in the UK [14].
- Patent Cooperation Treaty (PCT): This option allows you to seek protection in over 140 countries, giving you more flexibility. As Albright IP explains:
"The PCT route therefore provides flexibility and keeps your options open." – Albright IP [15]
If your focus is primarily on the UK market, a UK national phase application under the PCT route is more budget-friendly, costing about one-third of a Euro-PCT application [14].
After Filing: Examination and Maintenance
Once your application is submitted, there are several steps to secure and maintain your patent. Submit the required documents (form, detailed description, claims, abstract, drawings) and pay the applicable fees to the UK IPO. You’ll receive a filing date and application number, which establish your priority date. While the IPO will publish basic details of your application in the Patents Journal shortly after filing, the full application remains confidential for at least 18 months [13].
Six months after filing, the IPO issues a search report identifying prior art that could affect the novelty and inventive step of your invention. You’ll then need to request a substantive examination within six months of the search report’s publication. During this examination, an IPO examiner may ask for amendments to your claims, additional evidence, or further arguments until all requirements are satisfied.
Keep in mind that annual renewal fees start in the fourth year after filing and increase over time. If these fees aren’t paid, your patent will lapse.
Basic filing costs are approximately £310 if you handle the process yourself. This includes:
- Filing fees: £60 (online) or £90 (by post)
- Search fees: £150 (online) or £180 (by post)
- Examination fees: £100 (online) or £130 (by post)
However, hiring a patent attorney can add several thousand pounds to your costs [10][12].
Building Your Patent Portfolio
Developing a patent portfolio requires a thoughtful and gradual approach. Focus on protecting your core innovations and expanding your claims over time. For cultivated meat startups, this means safeguarding key technologies while planning for future improvements.
Protecting Your Core Technologies
To establish a strong foundation, prioritise patents that cover essential aspects of your technology, such as cell sources, production methods, and culture media.
Cell sources and differentiation are crucial areas for patent protection. Identifying and cultivating stable cell lines is a major challenge in the cultivated meat field, offering opportunities to secure intellectual property. Ensuring proper differentiation of cell types can also give your company a competitive edge [6].
Production processes represent another key focus. Protect your unique methods for culturing cells and producing meat, as well as the resulting products, compositions, and equipment [4]. These elements are integral to your business and should be prioritised.
Culture media innovations are particularly important for scaling production. Reducing the cost of culture media and improving its efficiency in converting nutrients into biomass are critical goals. Patents in this area are likely to attract interest from established food companies looking for partnerships [1].
The initial cell stock used to produce cultivated meat is another valuable asset. Protecting intellectual property related to large-scale cell culture methods, equipment, medium formulations, and additives tailored for livestock species could make your company an attractive partner for major food businesses [1].
When deciding what to patent, weigh the benefits of patents versus trade secrets. Patents provide 20 years of protection but are publicly disclosed, while trade secrets can last indefinitely but are vulnerable to reverse engineering or employee turnover [16].
Once you’ve secured patents for your core technologies, expand your portfolio by filing for improvements that broaden your claims.
Filing for Improvements and Applications
Expanding your claims incrementally is a smart strategy. Instead of relying on one or two broad patents, successful companies file multiple continuation, divisional, and new applications to secure broader claims over time [5].
A great example of this approach is Impossible Foods. Their patent U.S. 9,700,067 has led to at least five additional granted patents and four pending applications. Similarly, U.S. application 13/941,211 has resulted in 10 granted patents and seven pending applications [5]. This method allows companies to refine their claims as technology evolves, starting with narrow product claims and expanding to include related innovations.
Filing patents for products that incorporate novel ingredients can also strengthen your portfolio. For instance, Impossible Foods’ use of plant-derived heme made it easier to secure product patent claims. As intellectual property attorney Leonard R. Svensson explains:
"It is clear from a review of the different company patent portfolios that it will be difficult to obtain patent claims to cultured/substitute meat products per se. The inclusion of a new or different ingredient, like Impossible Foods' plant-derived heme, makes product patent claims easier to obtain." [5]
Successfully prosecuting patents often requires expert declarations and experimental evidence to demonstrate unexpected results [5]. This can be particularly challenging for products combining known ingredients, but it’s a worthwhile effort.
Beyond the final product, the cultivated meat field involves various technological aspects, including intermediate products, processes, additional ingredients, and machinery. Each of these areas presents opportunities for additional patent filings as your technology advances.
Once your domestic portfolio is well-established, it’s time to think globally.
Planning International Patent Strategy
Building a robust domestic portfolio sets the stage for international expansion. Focus on key markets like North America, Europe, and East Asia, while keeping an eye on emerging regions such as South America, Israel, Australia, and Southeast Asia [2].
By 2040, it’s estimated that 60% of meat will come from cells grown in bioreactors [17]. With over 150 cultivated meat companies operating across 26 countries and a cumulative industry investment of £2.2 billion in 2022, the competition for intellectual property is heating up [2].
Leading companies are already establishing significant global patent portfolios. As of November 2023, Upside Foods held 37 granted patents and 112 pending applications worldwide. Eat Just had 26 granted patents and 104 pending applications, while Aleph Farms maintained two granted patents and 68 pending applications [2].
When filing internationally, target markets where you plan to operate or license your technology. Draft applications with future improvements in mind to ensure flexibility. Securing patents in major markets not only deters competitors but also enhances your licensing and partnership opportunities [18]. Moreover, establishing intellectual property before entering new markets can reduce risks and strengthen your position [18].
A surge in patent filings around 2020 highlights the increasing competition in the cultivated meat sector [2]. Filing strategically and protecting your core innovations will be essential to staying ahead.
As Eugene Wang, co-founder and CEO of Sophie’s BioNutrients, puts it:
"The challenge isn't just creating sustainable food alternatives, but ensuring the industry remains open to innovation while protecting foundational breakthroughs." [16]
Common Patent Challenges
Navigating the patent landscape can be tricky, especially for cultivated meat startups. Anticipating and addressing potential challenges early can save significant time, money, and headaches down the road.
Writing Claims: Broad vs Specific
Patent claims are the backbone of your patent - they define the scope of your legal protection. Striking the right balance between broad and specific claims is key. Broad claims offer wider coverage but are more likely to face pushback during the examination process. They can also be harder to defend if challenged, as they are more likely to overlap with prior art. On the other hand, specific claims are easier to secure and defend but leave your invention more exposed to competitors who might tweak their designs to avoid infringement.
The best approach? A mix of both. Start with specific claims that clearly set your invention apart, then build out broader claims to secure more extensive protection. While drafting, think ahead - use language that accounts for potential variations or related technologies that might emerge in the future. This forward-thinking approach can help safeguard your innovation as the industry evolves [18].
Proving Your Invention is New and Different
For a patent to be granted, your invention needs to meet three key criteria: it must be novel, non-obvious, and fully enabled [6]. Demonstrating these qualities often requires solid evidence. Highlighting measurable benefits - like improvements in efficiency, safety, or production yield - can help underline your invention's uniqueness. Collaborating with patent attorneys ensures your application captures all patentable aspects while meeting the legal standards in the jurisdictions where you’re applying [19].
Establishing the originality of your invention is just one side of the coin. Avoiding infringement is equally critical.
Avoiding Patent Infringement
Before rolling out your cultivated meat technology, conducting a freedom-to-operate analysis is a must. Patent infringement disputes can be expensive and disruptive, potentially stalling your progress.
Take the example of Impossible Foods and Motif FoodWorks. In March 2022, Impossible Foods accused Motif of infringing on patents related to heme technology. The case concluded with a joint settlement, where Impossible Foods acquired Motif's heme-related business [18][20][21]. This case underscores the importance of thorough patent research and preparation.
To steer clear of such disputes, conduct detailed patent searches to identify existing patents that might overlap with your technology. This includes patents covering areas like cell lines, culture methods, bioreactor designs, and growth media. A freedom-to-operate analysis can confirm whether your innovations are clear of existing patents. In some cases, licensing existing patents may be a smarter, more cost-effective route than trying to work around them, especially for critical technologies that are hard to bypass.
Engaging intellectual property advisors early in the process can help you build a solid patent portfolio, avoid legal trouble, and position your startup for long-term success [18].

Working with Patent Attorneys
Navigating the world of patents can feel like a maze, especially in the realm of cultivated meat innovations. The intricacies of biotechnology patents require expertise, making a skilled patent attorney an essential ally in safeguarding your creations. For startups, the stakes are even higher, as limited resources and rapid development cycles add extra layers of complexity.
Finding the Right Patent Attorney
The success of your intellectual property strategy often hinges on choosing the right patent attorney. When it comes to cultivated meat technologies, industry knowledge is non-negotiable. Seek out attorneys who specialise in biotechnology and possess technical expertise that allows them to grasp the science behind your innovation. Their ability to translate complex concepts into precise legal language is crucial for navigating patent examinations successfully [33,34].
Equally important is finding someone who understands the unique pressures startups face. Attorneys experienced in working with early-stage companies are more likely to tailor their strategies to accommodate tight budgets and fast-moving timelines, without compromising on quality [22].
When evaluating potential attorneys, dive into their track record. Look at the number of patents they’ve filed and secured, the industries they’ve worked in, and their success rate with challenging biotechnology applications [22]. Don’t hesitate to ask for testimonials or case studies from other startups they’ve helped. Online legal directories and reviews can also provide valuable insights. During initial consultations, pay attention to how well they explain patent processes - clear communication is a strong indicator of their ability to guide you effectively [22].
Once you’ve found the right attorney, the focus shifts to managing patent costs wisely.
Managing Patent Costs
Patent expenses can escalate quickly, especially for startups, but a strategic approach can help keep them under control. Start by filing a provisional patent, which allows you to defer some costs. For micro-entities, the filing fee is around £55, with additional fees of approximately £360 and an issue fee of about £200. Professional drawings, often necessary, can range from £240 to £630 [27].
Preparation is key to minimising costs. Before engaging your attorney, create a detailed invention disclosure document. This should clearly outline your technology, its benefits, and how it stands out from existing solutions. Including visual representations can also save time and reduce the cost of technical drawings [26]. Focusing your application on one specific invention, rather than attempting to cover an entire product, can further streamline the process and reduce expenses while still offering meaningful protection [26].
It’s also worth exploring alternative fee arrangements with your attorney. Fixed-fee structures for specific tasks can simplify budgeting [28]. For those who qualify, the USPTO Patent Pro Bono Programme offers free legal assistance to individuals with income below 300–400% of the federal poverty guidelines [27].
Communicating with Your Attorney
Clear and consistent communication with your attorney is just as important as cost management. Establish open lines of communication early on and be proactive in your interactions. Responding promptly and providing clear information builds trust and keeps the process running smoothly [24]. When discussing technical details, avoid unnecessary jargon that could confuse or obscure your points [23].
Review all drafts of your application carefully to ensure accuracy and consistency. Ambiguities or errors can lead to delays, rejections, and increased costs [37,38]. Stay engaged throughout the process - regularly check in on timelines, discuss potential challenges, and explore ways to optimise spending with your attorney [25].
To avoid missed deadlines, monitor your application’s progress and set up automated alerts for key dates [23]. If the patent examiner raises issues, collaborate closely with your attorney to address them thoroughly. In some cases, requesting an interview with the examiner can help resolve concerns more efficiently than written correspondence alone [37,45].
Every interaction with your patent attorney is an opportunity to strengthen your intellectual property protections. By preparing well, communicating effectively, and staying actively involved, you can ensure that this professional partnership delivers maximum value.

With over 150 cultivated meat companies now operating across 26 countries [2], safeguarding your innovations has become essential for standing out and establishing a solid market position.
The importance of this protection is evident in the shifting investment patterns within the industry. After hitting a peak of £780 million in funding in 2021, investment saw a steep decline to £140 million by 2023 [30]. Yet, the right intellectual property (IP) strategy can still make a significant difference. Take UK-based Uncommon as an example. Their patent-pending cell differentiation technology played a key role in securing £24 million in Series A funding in 2023. Michael Sidler, partner at Red Alpine, highlighted their impact:
"Uncommon's completely novel approach holds immense potential to revolutionise the cultivated meat industry and overcome the scalability and pricing challenges that companies in this field face." [29]
Adopting an international strategy is equally important, with established markets in North America, Europe, and East Asia leading the way, while emerging regions present fresh opportunities [2].
Crafting an effective patent strategy involves finding the right balance between securing 20-year exclusivity, leveraging trade secrets, selecting the optimal claim scope, and aligning your IP efforts with your overall business goals [16].
This careful balancing act is key as the cultivated meat sector moves into its next phase. As the industry matures and consolidation begins, startups with well-developed patent portfolios will be in a stronger position to adapt and thrive [1]. Whether you're protecting new cell lines, advanced bioreactor designs, or innovative growth media formulations, patents form the backbone of long-term success in this rapidly evolving field.
The cultivated meat revolution is happening now, and patents will play a decisive role in determining which innovations make it to consumers' plates. By understanding the essentials outlined in this guide and collaborating with experienced patent professionals, you’re laying the groundwork to secure your place in the future of food.
