“Leason Ellis is a go-to firm for patent drafting as well as patent litigation. Its practitioners have the ability to understand the strategic importance of patent portfolios from a business perspective, creating significant added value over law outfits that do not look beyond the technical and legal aspects of patents. They have an excellent work ethic, deliver on time every time and genuinely have their clients’ business interests at heart.” Receiving individual praise are Elizabeth Barnhard, Michael Davitz, Edward Ellis, Melvin Garner and Robert Isackson. “Elizabeth has an excellent skill set for patent matters. She is approachable, easy to communicate with, dedicated, conscientious and acts with great integrity.” “Michael is extremely patient, generous with his time and is willing to explain the complexities of each of the patent applications to his clientele. He is very thoughtful, thorough, is able to get complex patents approved by the USPTO and he takes a personal interest in his patrons’ businesses.” “Edward is an excellent lawyer with a great track record. He is diligent, organised and highly professional. Edward never misses a deadline and his advice on how to deal with examiners is exceptional.” “Melvin has an exceptional understanding of the sophisticated technical details of an invention and is able to take an idea and turn it into valuable IP for his clients.” “Robert is superb. He managed to salvage a patent that had been filed by another law firm and then rejected multiple times by the USPTO. He is persistent, thorough and highly knowledgeable about IP law.” Also highly rated are Susie Cheng, David Leason and Yuval Marcus. PhD Cheng chairs the China practice group and is a member of the firm’s pharmaceutical and biotechnology department. She is a deft prosecutor who advises both US and Chinese players on how to obtain and protect their intellectual property. Managing partner Leason is an expert counsellor and strategist who helps entities of all sizes to procure valuable patents and then monetise them for maximum commercial gain. Marcus leads the litigation group and focuses on disputes in all aspects of intellectual property, from patents to trade secrets. Making their debut in the guide this year are Ralph Crispino and Jordan Garner. Crispino excels in managing and developing patent portfolios, particularly for patrons in the oil and gas industries.
