I understand that you want an opinion and recommendation on whether you should apply for a trademark, which is the registration of a brand, design, or sign that identifies a specific product, or a patent, which gives you exclussive rights to a product, design or invention you came up with, this gives you the intelectual property of said product.
I am a paralegal and work with a large law office in Honduras where they handle many different types of law for their clients all around the world. My work is to write out business contracts and many other different legal dcouments, which are then revised and supervised by an experienced attorney before they are sent to the client.
I believe I can help you solve your doubts by providing you with the pros and cons of either option and give you a formal recommendation to clear your doubts.
Off course whatever I write for you will be checked by a licensed attorney before you receive it.
Thank you for your consideration and attention to my proposal.
