Need help with a patent?

Patents are part of Intellectual Property ("IP") law. Inventors, designers, and creators are entitled to protect their unique work under the law. A patent gives your invention government protection from being copied or used without your permission. A patent lawyer will review your work, determine whether a patent can be filed to protect it, and then work with you to file a patent and protect your work from infringement. If you already hold an issued patent a patent attorney can protect it from unfair use. Asserting your rights is in your interest. Our national directory of attorneys features thousands of local patent lawyers.

Ask yourself the 3 C’s:

  • Credentials ‐ How many cases has this attorney worked on similar to yours?
  • Comfort ‐ Who are you most comfortable working with? Is the lawyer’s office nearby? How and how often will they get in touch with you?
  • Cost ‐ Have expected costs and fees been clearly explained to you? It’s OK to ask for an estimate.
