A patent and trademark attorney can help you navigate through the huge number of forms and filings that must be completed to obtain the patent or trademark. They can also advise you of any potential problems that may slow down the process and provide options for resolution before the problem even occurs.
While there are options to complete your patent or trademark application yourself, there are also a number of rules and regulations governing what can and cannot be patented and or trademarked that are more complex and technical than most people have time to research. An attorney that specializes in this field can provide information that is easy to understand on these complex topics.
