Why hire an intellectual property attorney?

Patent law is extremely complex. If you are intent on protecting the integrity of your idea or asset, you will want to obtain the help of an experienced patent attorney who is well versed in patent law and can help you navigate your case to a favorable conclusion. Attempting to prepare a patent application on your own, or attempting to enter into litigation on your own over an electrical or mechanical arts patent may prove costly, difficult, and ultimately unsuccessful.
