Patent attorneys in Springfield

Springfield, Illinois is home to 6 USPTO-registered patent practitioners. Working with a local practitioner can streamline in-person meetings for invention disclosures, signing inventor declarations, and reviewing prior-art search results — but every USPTO practitioner is licensed to practice nationally, so a non-local choice is also valid. Local firms with the most USPTO-registered practitioners include Heyl, Royster, Voekler & Allen and S I U School of Medicine.
