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.
Need an attorney in Chicago, IL?
Find the right attorney by reviewing and comparing our profiles of lawyers and their law firms, with details on each attorney and their colleague’s practice, experience, education, training, honors and fee structure. Carefully consider client reviews and recommendations from people just like you. If you have complex legal needs, a larger firm with multiple attorneys who can advise you in different areas may be the best fit. If your needs are more limited and very specific, consider a smaller firm. Speak with several Louisiana attorneys to find the one that is best for you.
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.
