Just as a new invention requires creativity and hard work, so does filing for a patent. Over the years, courts and the U.S. government have made it more difficult for inventors to meet the requirements to obtain a patent. As such, inventors who try to save money by filing their own patents run the risk of making costly, time-consuming mistakes.
The problem with making a mistake on a patent application is that the ill effects often occur well after the initial application. For example, an application may contain a diagram be too confusing for anyone other than the inventor to interpret or an application fails to fully describe the capabilities of the invention. Both situations could lead an inventor to spend an immense amount of legal fees to keep his or her creation, an amount much higher than using a reputable attorney from the beginning.
