Patenting Your Invention

New Laws Are In Place For Filing A Patent On Your Invention Idea

Significant changes to U.S. patent laws were put into effect in September 2011. Patent protection is now based on a first to file system, rather than the old first to invent system for all patents filed after March 16, 2013. The new patent laws also expanded the definition of prior art used in determining patentability. We caution all inventors to look carefully at any patent information or advice relating to patents to make sure that if it was published before September 2011, that such information is relevant and accurate. There is a ton of old and outdated information still out there, so be careful in making sure that the info you are using is based on the new laws.

A brief summary of the patent law changes is available here and a more detailed listing of changes is here.

How Much Does It Cost To File A Patent On Your Invention Idea?

It is important for new inventors to understand that the patenting process is a challenging and expensive one. How much does getting a patent cost? The simple answer is that it depends. It really depends on what your invention is about and what you want to file a patent on. The patent process is very expensive. We are not talking about hundreds of dollars, we are talking about thousands of dollars. And if you take your invention idea through the whole process, we are typically looking at total costs in the $5,000 to $30,000 range. 

The first step in getting a patent is doing a good patent search.  An inventor can do one on his own (and he should do one on his own first) but it is usually prudent to hire a professional to assist you with the search. A patent search with opinion will typically cost several thousand dollars. And that's just several thousand dollars spent to see if someone else has already has a patent for your idea.

Then the next step will be in filing a provisional or non provisional patent application.  It is safe to assume that the costs for simply filing a patent application for your invention will typically range anywhere from $5000 for the simplest patent to $20,000 for more complicated patents if you use an attorney or agent. 

And after you file your patent, you need to assume you will need several thousands more for post-filing costs.

If you can afford the thousands of dollars that it will cost you to start the patenting process and you have both the time and money to file a patent on your invention idea, then you should do a lot of research and reading about the patenting process. DO NOT JUST RELY ON A PATENTING INVENTION COMPANY TO FILE A PATENT FOR YOU! The more you know, the more you'll save and use your time and money wisely in your invention.  Here are resources to help you get started:
