Susan Rosenfield works in our intellectual property and IP litigation practice group where she counsels, advises and guides clients in diverse areas such as adoption, defense and enforcement of patent, trademark, copyright and trade secret rights. In all aspects of her work as an intellectual property attorney, Susan is always looking for the best ways to protect IP, and to identify IP as a value to clients’ businesses. As a registered patent attorney, she is experienced in the preparation and prosecution of trademark applications worldwide, and adept at putting in place the appropriate contracts to protect ownership or to preserve it with trade secret patents or registered copyrights and trademarks.

By guiding them based on their goals, and tailoring an IP protection plan to their needs, Susan represents companies and universities in a wide variety of industries, including agriculture, mining, food manufacturing, packaging and distribution, water treatment, pharmaceuticals, dietary supplements, cosmetics, educational training, software, solar energy, telecommunications, construction, financial services, hospitality, restaurants, hotels, entertainment, leisure/recreation, physical fitness and yoga, and equine. Throughout her work as an IP attorney, she has also represented lenders, such as banks and venture capitalists.

As the daughter of an attorney, Susan has always loved to write and she worked as a journalist while pursuing her undergrad before committing to the patent law specialty track. She went to law school at night, and worked full time for patent law firms during the day, starting her career in law performing trademark searches. In her current work as a patent and trademark attorney, she enjoys helping her clients by advancing their business and solving problems – often acting to avoid future problems, like picking a strong trademark to reduce potential conflict. She firmly believes business owners should focus on running their businesses, as she efficiently manages their intellectual property portfolios.

Susan and her family, along with four dogs of their own, have fostered countless puppies over the years with a soft spot for organizations like Luv of Dogz Fund and Saving Paws Rescue Arizona. She is also on the board of directors for Envision Therapeutic Horsemanship, and when not riding horses, you will probably find Susan in her vegetable garden.
