About the Firm

Eschweiler & Potashnik LLC is a boutique intellectual property law firm based in Ohio, U.S.A., focusing on patent prosecution, portfolio management, and IP strategy. Since 2001, we have provided legal counsel to companies worldwide in industries such as semiconductor processing, mobile communications, automotive technology, circuits, medical imaging, polymers, general chemistry, tire technology, biotechnology, oil-field technology, renewable energy, and computer software.

We work with clients to protect their intellectual property by concentrating on the preparation and prosecution of patent applications before the United States Patent and Trademark Office and foreign patent offices around the world. In many cases, we counsel U.S. and foreign companies directly. We also help clients find counsel through our extensive network of associated firms with similar practices around the world. Thousands of patents have issued to our clients through our work.

The firm also provides post-issuance services, such as reexamination and post-grant opposition analysis and filings, and inter partes reviews. Our practice also includes a broad range of patent counseling, such as infringement and validity analysis and the preparation of non-infringement, invalidity, and right-to-use opinions.
