  • IAM Patent 1000 Guide, (2017- present, OBWB ranked a Recommended IP Law Firm)
"Osha Bergman Watanabe & Burton LLP stands out as a discerning choice for high-level strategic prosecution and litigation work. When it comes to understanding the most complex technologies, this firm is one of the best in the business. Each of its practitioners brings incredible technical aptitude to the table and can easily relate to innovators to guide them through the patenting process with ease. Jonathan Osha draws on more than three decades of experience to quickly cut to the key issues and strategic points to find the commercial value for service users. Well-rounded Jeffrey Bergman staunchly protects the rights of companies that lead the way in the chemistry field and is hailed for his profound knowledge of patent law and complex problem-solving capabilities. IAM Patent 1000 newcomer Carlyn Burton is another chemistry maven who is appreciated for her straightforward advice. She understands the business value of patents and keeps up to date with developments in the chemistry industry to place her patrons in the most advantageous market position. Seema Mehta also makes her first appearance in the guide this year. She is a grounded practitioner who nurtures meaningful and long-term relationships with her clientele through being attuned to their needs and delivering business aligned results." (Excerpt from IAM Patent 1000 2023 write-up)

"OBWB is a sophisticated IP boutique that strikes the perfect balance between quality and value. Central to this is its efficacy in the onboarding of young and less expensive technical talent – a function of its US patent agent programme by which science and engineering graduates from top universities are apprenticed in patent practice and later encouraged to become USPTO-registered attorneys. Across its offices the firm made 31 hires in 2021, which puts significantly more resources at the disposal of its clients. Jonathan Osha and Jeffrey Bergman serve as global chair and managing partner, respectively. Osha is outstanding in his mentorship and his work as a strategic counsellor. He is also one of the foremost minds when it comes to AI-related IP matters. Bergman is a Swiss Army knife of a patent lawyer who can address all his patrons’ issues and problem solve flawlessly. He mines a rich seam of expertise in oilfield technologies."  (Excerpt from IAM Patent 1000 2022 write-up)

 - "Osha Liang rebranded as Osha Bergman Watanabe & Burton (OBWB) in October 2020, in celebration of the contributions made to the practice by a larger group of partners. As a result of this change, the top-specced boutique went into 2021 with added momentum undimmed by the Covid-19 pandemic, which has only put an added premium on the sort of superior quality work and service that the firm has always prioritised. Fielding locally qualified attorneys in Houston, Paris, Hangzhou and Tokyo, OBWB can cater to clients’ global patent prosecution needs; technical dexterity spanning all scientific and engineering disciplines is another USP. Global chair Jonathan Osha has promoted the use of sophisticated technologies and staffing approaches to drive efficiency while elevating quality, and in doing so has shown himself to be exceptionally mindful of clients’ needs. He maintains a vibrant practice which touches on many of the hottest areas of technological development. Manager of the Houston office Jeffrey Bergman prosecutes extensively in the chemical area, among others, and earns plaudits for his perspicacity on international patent law and insightfulopinions." (Excerpt from IAM Patent 1000 2021 write-up)

“Osha Liang’s use of sophisticated technical tools within a well-defined, highly polished patent prosecution system makes it one of the most efficient patenting firms in the entire country. Its US patent agent programme is another major differentiator: it hunts down science and engineering talent from top universities, offering a rigorous patent practice apprenticeship with a view to becoming USPTO-registered patent agents. The firm also has enviable international reach, with offices in Paris, Tokyo and Hangzhou complementing three US bases in Houston, Austin and Alexandria.”  (Excerpt from IAM Patent 1000 2020 write-up)
