- Q: What should I do initially to protect my invention?
-
A: Prepare in writing a disclosure of your invention. The writing does not have to be elaborate and can be merely handwritten and may include a drawing or sketch. Sign your disclosure as inventor in the presence of a Notary and have a friend or two witness and date the disclosure. This certifies dates of invention. Then, call us and set up an initial free consultation. We will also witness and date your disclosure so that you have proof that your invention was disclosed to us in confidence as your attorney. This witnessing will also add extra credibility to the invention dates. You will retain the original disclosure document in your possession in case it is ever needed to prove first dates of invention.
- Q: What type of patent protection is available?
-
A: Two types of patents are available, a utility patent an d a design patent. A utility patent protects a method or article of manufacture, compositions of matter and methods of doing business (including software and Internet patents). A design patent protects the outward ornamental appearance of an article. While design patents are less expensive to prepare and can be effective in some situations, they are of limited protection since they do not protect the concept or utilitarian function of the invention.
