Murgitroyd is a rapidly growing firm with innovation at its heart.

For over 50 years we’ve built a reputation as one of the world’s leading strategic IP firms. Trusted by global innovators and businesses to realise and protect the true value of their intellectual assets. History we may have, but we instead face forward. Our success lies in the positive relationships we build and our unrivalled breadth of expertise – from an unmatched technical knowledge to a proven commercial awareness.

We’re more than legal experts – we’re a strategic IP solutions firm with an unrivalled breadth of expertise. Our UK and European patent, trade mark and design attorneys bring together solid legal foundations, unmatched technical knowledge, and a commercial awareness that can drive growth and accelerate success.

We build relationships – globally. Our job is to protect and unlock the full potential of your innovations and ideas – not just in your country, but around the world. Our global team of specialists have an unrivalled knowledge in local laws and practices that provide a benchmark for advice and expertise wherever it’s needed to help you grow your business in markets you never thought possible, in ways you never imagined.

Our global office network spans Europe, North America and Asia. With over 440 employees (including over 350 attorneys) worldwide, our people have leading IP expertise across many industries including automotive, engineering & energy; consumer brands & services; chemistry & materials; life sciences & healthcare; and technology, media & telecoms.

Adams and Reese's Global IP Team is internationally renowned, earning acclaim from both clients and attorney rating services. Our expertise extends across Europe, Asia, South America, and North America, serving multinational and middle-market companies. With a focus on trademark, patent, and copyright matters, we provide strategic counsel on a wide range of intellectual property issues.

Our success often lies in mitigating risk and preventing litigation or resolving claims swiftly. In unavoidable litigation scenarios, we excel at exposing opponents' weaknesses, globalizing disputes, and reaching resolutions that favor our clients commercially.

A remarkable example of our prowess occurred when one of Singapore's largest publicly traded companies required representation in a U.S.-based trademark dispute. This bet-the-company case involved our client's brand name and multiple pending actions in 12 nations. Leveraging global strategies, we meticulously analyzed the opposing party's portfolio—a well-funded Belgian company. Our comprehensive approach proved effective, leading to a settlement before dispositive motions were necessary. As a result, our client continues to use its name, while the other company does not.

In another challenging feat, we engaged in two complex U.S. patent infringement cases, going head-to-head with a top IP law firm in the country to protect our client's patents. The case was successfully settled with a judgment in our favor, securing a total victory for our client. Our team had written and registered these patents during a decade of dedicated service.

Clients appreciate the experience and knowledge we bring to the table for sophisticated matters. Key tenets of our team's culture include a truly global perspective that creates leverage and advantages for clients, swift delivery of work that adds value, prompt responsiveness to calls and emails, and the ability to manage services effectively across practices and offices to enhance efficiencies and benefit clients.

For companies in major markets like Hong Kong, London, and New York seeking to introduce new international brands, our trademark attorneys offer valuable assistance. Leveraging years of experience, we guide these clients through the complex multinational brand-clearance process to find a unique brand name. We then register these new brands, providing clients the confidence to launch them securely.

Addressing a growing concern among global companies, we focus on recapturing sales lost to online counterfeiting and repairing brand damage caused by counterfeit products. This is an increasingly significant IP issue for many businesses. Our team has developed innovative anti-counterfeiting and anti-piracy initiatives, collaborating with clients to devise tailored enforcement solutions. These strategies go beyond mere reactive measures and effectively combat online pirates, resulting in a significant impact on our clients' bottom lines.

At Adams and Reese's Global IP Team, we pride ourselves on providing exemplary service, strategic counsel, and successful outcomes for our clients on both national and international levels. Our commitment to excellence and dedication to intellectual property matters have made us a trusted partner for companies seeking to safeguard and maximize the value of their intellectual assets worldwide.

The HG Law team has extensive experience with representing clients of all sizes and across a multitude of industries around the globe in connection with intellectual property matters.

HG Law is selective in hiring talented candidates with exceptional legal and technical/scientific backgrounds. We invest in our legal team and support staff. This includes providing each person with opportunities to work on a wide scope of projects in addition to specializing in a respective practice area.

Sideman & Bancroft is one of the premier brand protection law firms in the United States. Our team includes highly experienced lawyers and former federal prosecutors, and global security and brand protection experts with extensive backgrounds leading anti-counterfeiting, anti-piracy and customs interdiction and investigation programs in both private companies and law enforcement agencies. We provide customized and scalable brand protection solutions designed to enable clients to achieve their goals for trademark protection and worldwide branding in all stages of a brand’s life cycle.

The value of trademarks, service marks and trade dress is greater than ever before. We routinely prosecute and defend infringement, dilution, unfair competition and false advertising claims involving both registered and unregistered trademarks and service marks, in addition to pursuing a wide variety of trade dress claims. Protection of a global brand means understanding risks and concerns regarding enforcement issues in the U.S. as well as in foreign jurisdictions. We obtain ex parte writs of seizure for counterfeit parts and labels in the U.S. and other countries. In collaboration with local counsel, we pursue and defend trademark and service mark claims in jurisdictions around the world.

The firm achieves tremendous results for clients by combining the traditional intellectual property and brand protection practices of counseling, prosecution and enforcement with specialty components such as:

• Criminal intellectual property enforcement
• Criminal and civil gray market investigations and enforcement
• Global investigation management
• Online anti-counterfeit monitoring
• Global customs advice and program development

In particular, the team assists clients in implementing brand protection strategies to halt the importation of counterfeit goods and prevent the sale of counterfeit products. As part of this effort, we help companies target and investigate counterfeit traffickers, and then assemble and analyze evidence to support successful criminal investigations and prosecutions as well as civil litigation resulting in asset freezes and other remedies.

Since 2001, our team has actively worked with the Federal Bureau of Investigation, Homeland Security Investigations, Secret Service and other state and federal law enforcement agencies throughout the U.S. in its representation of victim companies, resulting in dozens of criminal convictions, jail sentences and restitution orders. Relying on our team’s international law enforcement experience, we also actively coordinate investigations and law enforcement referrals in jurisdictions all over the world.

Areas of specialism
EIP is a leading IP law firm advising on high-value and complex patent matters. Our multidisciplinary team combines patent attorneys, litigators and commercial IP lawyers. EIP is located in key strategic markets – Germany, Sweden, the United Kingdom and the United States.

The benefit of combining attorneys and litigators is well illustrated by EIP’s successful representation of clients in high-stakes patent litigation before the UK High Court, the Court of Appeal and Supreme Court, and before the German district and federal courts.

Aside from the more mainstream drafting and prosecution practices, EIP’s patent attorneys work closely with the litigation team in the United Kingdom and Germany, providing additional technical expertise on large-scale international patent litigation matters. We also have a dedicated, experienced and technically skilled team supporting clients before the new Unified Patent Court (UPC). EIP brings together highly recognised litigation lawyers and European patent attorneys that are experienced in English and German across all technical fields and since the UPC opened its doors also has experience from a number of cases before different venues of the new court.

EIP is increasingly involved in advisory and strategic project work in relation to the enforcement of patent rights, including portfolio analyses, infringement and validity analyses and claim charting, as well as strategic IP advice such as due diligence related to acquisitions and joint ventures. Team members often counsel clients on strategic patent portfolio management and development matters, and EIP has been retained to assist in developing high-level IP strategies for some of the world’s largest companies. Recently, after strategic hire, the team can also advise on China related matters.

To complement the high-value patent advice we already provide to our clients, we give commercial advice on the exploitation and use of IP rights and ancillary issues arising in relation to data protection and rights of privacy.

EIP has represented clients in hundreds of oppositions before the EPO over the past two decades and represent clients in person at hearings at the EPO in Munich, The Hague and Berlin, as well as via videoconference hearings.

The firm’s integrated team of patent attorneys, litigators and paralegals can act in national court litigation alongside EPO opposition proceedings for a seamless, consistent and effective service.

Clients
EIP has a diverse international client base, advising blue-chip companies through to small and mid-sized enterprises. Clients include Nokia, VISA, Airbus, AP Moller-Maersk, Pulpex, Sonos, Broadcom and Optis.

Clients choose EIP for its commercial outlook, in-house experience, honest opinions and pioneering approach to dealing with patents. Our attorneys and lawyers have considerable technical knowledge in the areas of high tech, advanced engineering, chemistry, life sciences, biotechnology, pharmaceuticals, healthcare, medical technology and energy.

Firm overview
EIP was established in 2000 and has rapidly grown to be a leading IP firm with 36 partners and more than 180 staff practising from its four UK offices in Bath, Cardiff, Leeds and London, its German office in Düsseldorf, its Sweden office in Stockholm and its US office in Denver, Colorado.

In 2024 EIP was named “European Patent Disputes Firm of the Year” at Managing Intellectual Property EMEA awards for the third time. EIP is a Legal 500, Chambers & Partners, IAM Patent 1000, IP Stars and JUVE-recommended firm, as well as being one of four firms achieving gold rankings all six categories in the Financial Times' Europe's Leading Patent Law Firms award list: Biotechnology, Food & Healthcare, Chemistry & Pharmacy, Electrical Engineering & Physics, IT & Software, Materials & Nanotechnology, and Mechanical Engineering.

Notable cases
EIP has built an enviable reputation in patent litigation and has won the following high-profile cases for clients:

• EIP secured a landmark victory in the UK Supreme Court for its clients Unwired Planet and Conversant Wireless, in Unwired Planet v Huawei and Conversant Wireless v Huawei & ZTE – the most eagerly anticipated telecoms cases in years. The Supreme Court’s combined ruling defines the licensing of patented technology considered essential to the international standards for previous and future generations of wireless telecommunications technology.
• EIP secured a significant victory for client Conversant Wireless in Germany. EIP successfully asserted a standard essential patent (SEP) for Conversant against Stuttgart carmaker Daimler in a dispute that will have repercussions across the sector.
• EIP obtained a victory in the Düsseldorf District Court for its client Conversant Wireless in two patent infringement decisions against Huawei and ZTE. The court affirmed infringement of two 3G-related SEPs by Huawei and ZTE products. Subject to enforcement, the ruling awarded, among other things, an injunction against both companies, confirming a previous but non-accepted licence offer by Conversant as fair, reasonable and non-discriminatory.

Grüneberg Global IP turned the traditional law firm model on its head, to set the gold standard for in-depth, cost-efficient patent counsel. 

In an evolving market, Grüneberg Global IP offers cost savings for patent budgets. With innovative office concepts and paper-free law practice management systems, the firm reduced overhead, bringing prices to competitive levels. State-of-the-art cloud-based file and docket management software provide robust cybersecurity and increased efficiency, within a reasonable technology budget.

The firm’s experienced attorneys and staff maintain high quality. Several team members have previously worked at the International Trade Commission, the Court of Appeals for the Federal Circuit, the U.S. Patent and Trademark Office, in-house positions, large general-practice firms, and IP boutiques. While the firm itself started in 2017, the firm’s staff leadership has worked in managerial and supervisory roles in larger, high-volume patent prosecution firms and in-house at large companies, thus carrying forward decades of institutional knowledge in an innovative, efficient environment.

The attorneys at Grüneberg Global IP prosecute U.S. and international patent applications with skill and experience. Thousands of U.S. patents have issued as a result of the efforts of the attorneys on the Grüneberg Global IP team.

With its low-overhead model, Grüneberg Global IP can prosecute applications within competitive flat-rate pricing structures.

The attorneys at Grüneberg Global IP have experience with numerous counseling, freedom-to-operate, and post-grant matters. The firm frequently provides freedom-to-operate, invalidity, and noninfringement opinions for clients. In addition the attorneys at Grüneberg Global IP have performed product IP-clearance projects, and have helped clients navigate pharmaceutical Hatch-Waxman exclusivity and subject matter eligibility. The firm also achieved positive outcomes for clients in reexamination and in inter partes review.

When in-house counsel needs to operate on a budget, the firm can work within agreed-upon price ceilings to provide thorough outside patent counsel with predictable costs.

Large corporations, including Fortune 50 companies and Fortune Global 200 companies trust Grüneberg Global IP with building patent portfolios and operating in competitive IP environments. The firm serves companies in Europe, Asia, and the Americas, supporting in-house counsel in chemical, pharmaceutical, biotechnology, medical devices, construction, AI, machine learning, electronics, and tools and machinery industries.

Desmarais LLP is a premier intellectual property litigation firm with approximately 75 attorneys across its New York, San Francisco, and Washington, D.C. offices. The firm has successfully tried and won several of the industry’s most high-profile patent cases in recent years, representing some of the world’s largest companies.

The firm works on complex, often technology-focused disputes, handling every step of the litigation process. The breadth of Desmarais LLP’s work spans a wide range of subjects and technologies, and the firm has obtained successful trial results for clients – both plaintiffs and defendants – in dozens of patent infringement cases and other intellectual property areas.

Litigation

Desmarais LLP handles all patent litigation stages and has significant trial experience in every major forum for technology and life sciences in the United States and elsewhere. The firm has successfully tried cases before judges and juries throughout the U.S., before administrative bodies (including the International Trade Commission and the Patent Trial and Appeal Board), and in front of arbitration panels. Desmarais LLP’s patent infringement successes include winning trials across a host of district courts, preserving both offensive and defensive victories on appeal, obtaining reversals of adverse results, and steering the development of substantive law in clients’ interests in a variety of subject matter areas.

The firm’s patent litigation experience spans numerous industries covering technologies including biotech innovations, chemicals, consumer electronics, medical devices, pharmaceuticals, semiconductors, software, telecommunications, and transportation. The firm’s High-Tech Practice, International Trade Commission Practice, Life Sciences and Medical Device Practice, and Post-Grant Practice also litigate in areas beyond patent disputes, including antitrust, contracts, counterfeiting, fraud, trade dress, trademarks, trade secrets, and unfair competition.

Additionally, the firm’s Pro Bono Practice is committed to serving the community, partnering with organizations such as the SDNY Pro Se Clerk’s Office, the Veterans Consortium, Immigration Equality, and Volunteer Lawyers for the Arts. Each year, Desmarais LLP recognizes attorneys and paralegals who make substantial contributions as part of its Pro Bono Challenge.

Innovative Fee Structures

Desmarais LLP is an industry trailblazer in alternative fee arrangements (AFAs). The firm has abandoned the traditional (and frequently inefficient) billable-hour model in favor of fee arrangements more closely tailored to clients’ interests. This flexible and innovative approach sets it apart from other top-tier firms that litigate similarly large, complex cases.

For clients who prefer predictability, the firm provides flat-fee arrangements negotiated at the outset of the matter, and for those seeking a shared-risk approach, the firm is open to contingent fee arrangements and hybrid structures tailored to the client and the case. Additionally, the firm offers flat-fee billing for expenses. This gives clients clearer budgeting for the duration of the matter (though monthly fees can vary based on the stage of the litigation).

Benefits and Compensation

Desmarais LLP is a leader in benefits and compensation – paying associates salaries that top the New York scale and year-end bonuses for high performers that significantly exceed the market rate. The firm covers 100% of health insurance premiums for all employees and their dependents, meaning attorneys and staff having no monthly costs, except when they receive medical services (e.g., copays). The firm also contributes 4% annually to employees’ 401(k)s – not as a match but as an automatic contribution, even if employees are not paying into their retirement accounts. In addition to short-term disability for birth mothers, Desmarais LLP also provides 12 weeks of paid parental leave for all lawyers and staff, regardless of gender or whether they are adoptive parents.

Diversity

Desmarais LLP is committed to maintaining a workplace that respects all cultures, backgrounds, beliefs, and identities. The firm believes its attorneys’ and staff’s diverse set of experiences play a valuable role in helping achieve creative and effective solutions when dealing with clients’ most challenging cases. The firm’s Diversity Committee promotes an inclusive work environment and focuses on recruiting and retaining lawyers from diverse backgrounds. Desmarais LLP also regularly sponsors student organizations dedicated to promoting diversity and inclusion at law schools and sponsors the annual ChIPs Global Summit dedicated to the advancement of women in technology, law, and policy.

As one of the first firms to file a petition and subsequently argue a post-grant review of a covered business method case following the implementation of the America Invents Act, Finnegan is one of the busiest law firms representing petitioners and patent owners in patent office invalidity proceedings in the U.S. and Europe, including ex parte reexaminations, inter partes and post-grant reviews, nullity proceedings, oppositions, and third-party observations.
