1 intellectual property attorney in and around Sioux Falls, South Dakota, with phone numbers and websites. Patents, trademarks and copyright protection and enforcement.
Patent work requires a lawyer registered with the USPTO; trademark filings do not. Ask for flat-fee quotes on searches and applications.
Most firms offer a free or low-cost first consultation. Call two or three, ask who will actually handle your case, how they bill, and how often you will hear from them. Check that the lawyer is licensed with the South Dakota State Bar.
