Dorothy Wu Chiang

As Counsel at Sunstein, Ms. Chiang concentrates her practice in strategic patent portfolio development, product clearance, opinions, and post-grant proceedings before the U.S. Patent & Trademark Office. Her clients range from start-ups and premier academic institutions to mid-sized and multinational companies.


  • Ms. Chiang regularly develops and manages patent portfolios for high technology companies. Her counsel assists clients in refining their business and technological positions in the marketplace, and she has created assets that increase the valuation of companies before prospective investors and attract the interest of patent investment firms. As part of her practice, she advises companies on offensive and defensive measures against competitor products and patent portfolios.
  • Her technical versatility enables her to represent clients in areas such as electrical systems and electronics, high performance computing, computer hardware and software, augmented reality, desalination systems, robotics, orthotics, navigation systems, Internet technologies, image and video processing, data storage systems, and photovoltaics.
  • Before entering private practice, Ms. Chiang served as a patent examiner at the U.S. Patent & Trademark Office, experience that she relies on to maneuver applications to allowance as issued patents.
  • Ms. Chiang also represents companies, both patent owners and opponents, in inter partes reviews before the Patent Trial and Appeal Board (PTAB), and she has litigated appeals in these proceedings before the Court of Appeals for the Federal Circuit.
