"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)
