Need help with intellectual property law?
Intellectual Property (“IP”) attorneys work with individuals or businesses to protect their unique creations. If you are an inventor, writer, artist, designer, composer, or artist your work is entitled to protection under the law. Lawyers and law firms focused on Intellectual Property law will help you understand and exercise these rights and protect assets from being infringed, misappropriated, copied or plagiarized whether the infringement has already occurred or not. Proactively asserting your intellectual property rights is in your interest.
Need an attorney in Philadelphia, PA?
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.
