World Trademark Review


OLIVARES has a mantelpiece full of industry awards, a client roster stacked with household-name brands, a deep squad of experts, an outstanding résumé of trademark prosecution and enforcement victories and a long track record of improving the Mexican IP system; quite clearly, then, it is a leader in the field. There are a lot of individuals to get through, but Sergio Olivares and “major influencer” Antonio Belaunzarán Martínez are good names to start with – they provide inspiring leadership not just to the firm but also to the entire market, and are a wellspring of innovation in terms of IP practice and client service delivery in Mexico. Several others fit the thought-leader mould, too, including Alejandro Luna Fandiño and Luis Schmidt: Luna is a big-time litigator and a regulatory law aficionado; Schmidt is the top name in Mexico in the media and entertainment sector. Busy in the same, Abraham Díaz flexes high-calibre copyright expertise; but he’s a superb IP all-rounder and great on matters at the intersection of trademark and IT law, such as domain names and data privacy. Alonso Camargo is the embodiment of one of the firm’s greatest strengths – an ability to communicate with and get results out of the Mexican Institute of Industrial Property (IMPI). Commentators describe him as “responsive, client focused, fast working and highly knowledgeable”. Should obstacles arise during prosecution, Daniel Sanchez can sort them out effortlessly thanks to his mastery of administrative litigation proceedings before IMPI. He excels in heavily regulated industry sectors.

One client says: “We chose them based on their reputation, and we have continued to use them because they have lived up to expectations.” Luna is almost unanimously praised by his peers for his work in contentious matters: “You will hear Alejandro’s name wherever you go, especially in Mexico. His skill is unmatched.” Peers also praise Sanchez’s practice stating that he “continues to impress those around him.” Gustavo Alcocer is also a key contact as he co-chairs the life sciences and pharmaceuticals group. He is described as “a fabulous lawyer who always understands the client’s needs from both the legal and business perspectives.” The majority of the firm’s patent work stems from the pharmaceutical sector, with noteworthy clients such as Takeda, Bristol, Celgene and Abbvie. Sergio Olivares Jr remains an important contact who “has a great understanding of client needs.” He most recently collaborated with Luna on the drafting of a proposal of changes in the law to comply with the TPP obligations on behalf of client AMIIF. Armando Arenas is in charge of patent infringement and invalidity litigation in the pharmaceutical sector.”

WTR 1000





What WTR 1000 says about OLIVARES:

“OLIVARES is outstanding as an IP firm, but it has a broad commercial view of the world”; while upholding “the highest ethical and quality standards”, it is “hugely influential in the Mexican market”. Few, if any, can navigate Mexico’s enforcement system and infrastructure as well as OLIVARES, which is known for pioneering many of the most effective litigation strategies; it is worth noting that sophisticated anti-counterfeiting work – which is dangerous due to its links to organised crime in Mexico – has become a staple of its contentious practice in recent years. With five on the list – Sergio OlivaresAlejandro Luna FandiñoDaniel SanchezAntonio Belaunzarán Martínez and Abraham Díaz – OLIVARES has more WTR 1000-ranked enforcement and litigation partners than any other firm in Mexico. Firm talisman Sergio Olivares oversees the organisation with poise and has kept it at the cutting edge throughout his tenure of more than 20 years as a partner, overseeing initiatives which include the opening of new industry and practice groups. The formalisation of an administrative law unit, headed by Luna Fandiño, is a recent example of this. Luna Fandiño has done much to shape the development of Mexico’s litigation and regulatory environments and is a reliable ally for any party in a dispute. Sanchez also blends litigation and regulatory wisdom and is an ace when it comes to administrative proceedings at the Mexican Institute of Industrial Property (IMPI). The sophistication of Belaunzaran Martinez’s legal thinking is the talk of the town; he has an ardent following of famous brand names, but also generously gives his time to mentoring younger lawyers within the organisation. Diaz adds value for those with diverse portfolios as a result of his tripartite copyright, trademark and unfair competition expertise. An anchor of the firm’s smooth-running, efficient and business-oriented prosecution practice, Alonso Camargo is the sixth partner ranked in the guide. Clients love his unpretentious style and draw confidence from his complete dedication to their cause.”

IAM Patent 1000

Litigation, Gold ranked firm

Prosecution, highly recommended firm





What IAM Patent 1000 says about OLIVARES:

Among the biggest firms in volume of filings undertaken, Olivares has the edge when it comes to quality.” The boutique maintains a tight grip on a substantial corner of the market and has accrued an enviable mountain of respect, built up through its accomplished handling of the prosecution, litigation and transactional trinity. Acutely aware of the IP aspects of domestic law and international agreements, the partners invest their regulatory and technical expertise into multiple overlapping industry and practice groups, ensuring that every instruction is dealt with according to the legal and sector-specific requirements of the buyer. When the going gets tough, the litigation set is not afraid to get aggressive. In recent cases it has forced IMPI to reconsider and clarify its patentability criteria, winning victories for clients, including Novartis, while simultaneously altering the course of the country’s patent law. Leading the charge, Alejandro Luna Fandiño is “an extraordinary litigator, active at every level – from IMPI to the Mexican Supreme Court and back again”. Acting on behalf of Eli Lilly – and in the country’s highest court – he is due to battle for a precedent that will establish the parameters for the Roche-Bolar exemption in the national market. “In every instruction, he is responsive and insightful, developing and implementing strategies which incorporate his deep and thorough understanding of the legal issues and reflect the practical realities of litigation in the country.” He comes recommended as “a knowledgeable IP practitioner offering creative and cost-effective advice”. Fellow litigation team co-chairs Daniel Sanchez and Sergio Olivares share Luna’s polymathic abilities; Sanchez is a force to be reckoned with in litigation and possesses a fine mind for regulatory and administrative issues, earning him a strong following among life sciences and biotech concerns. Olivares is equally skilled in prosecution and confrontational matters. He applies his wide array of talents and international experience to spearheading the development of the practice’s comprehensive offering.
