Prepare for a detailed discussion before you meet with a patent attorney

To represent you effectively, your patent attorney needs to understand your idea inside and out. To boost your chances of getting a patent, you need to know how to explain your idea to your lawyer. Organize every bit of information to allow you to articulate what your invention is and how it works. Patent attorneys, nor the USPTO, require you to have a fully operational prototype or even good drawings, and they are good at deciphering the “chicken scratch on the napkin” moments, but the more that you can provide, the smoother the process will be.


Understand the fee structure.  We offer flat fee patent service.

Different patent law firms have different payment policies. To avoid fees that constantly increase as the process goes forward, consider partnering with a firm like Kaufhold & Dix that offers a flat fee without hidden costs. Our flat fee covers everything, including the drawings, writing of the application, and responses to office actions (responses to Patent Office rejections and inquiries). Before committing to an attorney, don’t be afraid to ask for a cost breakdown.

Do I need a patent, trademark, or copyright?

Generally speaking, trademarks are used to indicate a source of a good, while a patent would protect the good itself. Copyrights, in a nutshell, are used to protect original works of art.

What types of patent protection are there?

The two main categories of patent protection are design patents and utility patents. Design patents cover what it looks like. Utility patents protect the article being manufactured or the method of either making the article or performing a particular task.

I intend on selling my idea, why do I need a patent?

If you intend on licensing your idea, you will generally need something filed or you have no property to license. Also, many larger companies would rather deal with inventors who already have a patent or have patent pending status.

Do I need a prototype?

You do not need a prototype but instead only need to be able to explain to us how your invention works.
