Thomas Edison famously said "genius is 1 percent inspiration, 99 percent perspiration."
Perhaps Edison should have carved out a couple of percentage points for figuring out how to get a patent.
Hiring a patent attorney can cost as much as $10,000 for a utility patent, the most common form. That covers "any new and useful process, machine, article of manufacture or composition of matter, or any new and useful improvement thereof," according to the U.S. Patent Office.
The less common but cheaper alternative is a design patent, which covers "a new, original and ornamental design for an article of manufacture."
Either way, experts say a visit to a patent attorney is an important step for any inventor.
"I would absolutely encourage individual inventors to work with a patent attorney, whether it's a solo practitioner or a firm," said Bill Munck, a patent lawyer with Dallas' Munck Carter LLP.
Robert Wise, a former patent examiner with the Patent Office, said knowing the different types of patents is just one of the skills needed to navigate the process.
He noted that many of the patent companies that advertise on TV and elsewhere take advantage of inventors who aren't aware of that complexity.
