Hayley Ostrin is an associate IP attorney within Merchant & Gould’s Washington, D.C. office. Her practice is focused on Section 337 investigations before the U.S. International Trade Commission, which involve unfair and injurious competition in trade. Hayley also assists companies with other IP matters, such as district court litigation and IP counseling. 

Supporting Those on Both Sides of Section 337 Investigations

Section 337 involves unfair practices that affect imported goods, such as patent, copyright, and trademark infringement, as well as other unfair acts such as trade secret misappropriation and false designation of origin. Hayley is proud to support both respondents and complainants in Section 337 matters. 

Whether your business’s rights are being infringed upon by incoming products or your business is accused of an unfair trade practice, Hayley can help.

Experienced in ITC Procedures

Before joining Merchant & Gould, Hayley served as a Section 337 litigation attorney for a boutique firm that specialized in Section 337 investigations. 

During this time, she became familiar with all ITC procedures, the Administrative Law Judges, hearing strategies, and the other nuances of this unique practice area. She understands what moves you can, and should, make and how to help you traverse an often underutilized forum.

Serving With a Background in Bioengineering & Business

Hayley has always had a passion for innovation. While receiving her Master of Science in Bioengineering, she worked as a research assistant and performed tasks such as synthesizing nanomaterials, modeling biodegradable implants, and designing imaging systems.

Realizing she wanted more, Hayley then entered a new chapter as a successful Sales Engineer, where she oversaw product management for multiple Fortune 500 companies. It was during this time that she learned the realities of business, the supply chain and how trade and intellectual property affected a company’s ability to innovate.

Now, her work as a Section 337 litigation attorney combines her knowledge of engineering and business. From protecting your technical products and assets to advising you on the best next step for your business, Hayley delivers.

“Law Practice Requires a Holistic Approach”

Hayley believes that a skilled attorney must look at both a business and the law when developing solutions. Even businesses that are under attack may find that pursuing a case strains their finances even more. Hayley is honest, ensuring companies understand their rights, responsibilities and any potential outcomes.

Hayley looks at each case individually. After all, no two businesses are the same, and neither are legal cases.

I care about my clients. I want to make sure they know that I’m always going to do my best to advocate for them and to be honest with them about their chances of success. I’m not a copy-and-paste attorney—I look at each case with fresh eyes.

When Hayley isn’t advocating on behalf of her clients, you’ll find her swimming, walking her dog or practicing yoga.
