Hubbs, Enatsky & Auito Expands IP Law Firm in Northern Virginia and Japan

We are excited to announce the formation of Hubbs, Enatsky & Auito PLLC (“HEA”) (previously, Hubbs, Enatsky & Inoue PLLC), an intellectual property law firm with fully functional offices in the United States and Japan. Our name change reflects HEA’s expansion in services and personnel in its United States and Japan offices.

The firm has more than doubled in size with the addition of Darrin Auito, Hirotsuna Yamashita, Jessica Harrison, and James Judge.  These new members bring many years of experience as counsel at top 25 law firms and examiners and senior level staff (SME and Central Reexamination Unit Supervisor) at the United States Patent and Trademark Office (USPTO) and the Japan Patent Office (Chief Appeal Examiner and Director).   These members have participated in dozens of AIA post grant proceedings.  HEA is thrilled to add this mix of administrative knowledge, technical and litigation experience to our practice.
