* Drawing That Explains Patent Laws

From Chief Justice to the patent examiner.

Hello, my name is Erik. I’m a lawyer. And I like to do drawings. Would you like to see some of my drawings? Here are some of my other drawings:

On 10/19/05, the daughter of one of my MIT friends shadowed me for a day at work as part of a school project. One of the good things about spending time with children is that it forces you to explain things in simple terms. When my friend’s daughter saw all of the books in my office (yes, we still use books occasionally), she asked, “What’s in all of those books?”

So I drew the above drawing to explain all of the patent laws, how they are related, and how they change.

I drew this as a pyramid with the shorter laws at the top and the longer ones at the bottom.

At the top of the pyramid is the United States Constitution. The structure of our government comes from the Constitution. So do many individual rights. It is our country’s most important legal document. Article 1 Section 8 of the Constitution says:

“The Congress shall have Power … To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries;”

So patent rights and copyright rights come from the same clause in the Constitution. Oddly, the Constitution says nothing about trademark rights. And in our government, the Patent Office and the Trademark Office are combined (in the United States Patent and Trademark Office (USPTO)), but the Copyright Office is separate. So Congress doesn’t always do things the way the drafters of the Constitution thought that they would.

Next in the pyramid (working top to bottom) is the Patent Act. When our lawmakers in Congress (the Senate and the House of Representatives) want to make a new law, they write it, debate on it, and if they agree on it, then the new law becomes part of the United States Code. The United States Code is divided into smaller pieces called titles, parts, chapters, and sections. The Patent Act is the short name for our patent laws, which exist in Title 35 of the United States Code (35 USC for short).

The version of the Patent Act that I use is about 88 pages long. So the Constitution says one sentence about how Congress can create patent laws, and Congress created 88 pages of patent laws.

Next in the pyramid is the Patent Rules (also called patent regulations). Congress writes the laws, but different agencies of the government have to carry out those laws. The Federal Rules are the rules that the agencies write to help explain the laws and how they’ll be carried out. For patent laws, the USPTO writes the Patent Rules, and those appear in Title 37 of the Code of Federal Regulations (37 CFR for short).

The version of the Patent Rules that I use is about 336 pages long. So we’ve gone from one sentence (Constitution) to 88 pages (Patent Act) to 336 pages (Patent Rules).

The bottom of the pyramid is the Manual of Patent Examining Procedure (MPEP). The MPEP was written by the USPTO for patent examiners to help them do their jobs. Most patent examiners are not lawyers. So the MPEP is designed to help them understand and apply patent law (the Constitution, the Patent Act, and the Patent Rules). The MPEP is the most frequently used reference book for patent examiners. So it is helpful for patent lawyers like me to know the MPEP.

The version of the MPEP that I use is about 3000 pages long. So we’ve gone from one sentence (Constitution) to 88 pages (Patent Act) to 336 pages (Patent Rules) to 3000 pages (MPEP).

The fun part about the patent laws is that they are constantly changing. The job of the courts (and ultimately the Supreme Court) is to determine what the law is – what it means. So whenever there is a patent dispute that ends up in court, the courts will be interpreting what the patent laws (the Constitution and the Patent Act) mean. Congress can also change the Patent Act, but that is harder to do. And the people of the United States can change the Constitution, but that is even harder to do.

At the same time, the USPTO is constantly revising the Patent Rules and the MPEP. And sometimes the way the USPTO thinks the patent laws should be applied differs from how the courts think the patent laws should be applied.


My drawing could be better. And my explanation could be better. But again, I drew this for a child, so it’s a good place to start. The main point is that there are four types of patent laws: the Constitution, the Patent Act, the Patent Rules, and the MPEP. And patent practitioners like me have to do lots of reading to keep up with all of the changes. Ultimately, the Constitution’s patent clause is the most important patent law. But on a daily basis, the MPEP is the most important document for a patent lawyer.

  1. Hi Erik

    We have exchanged some emails but I lost your address. Could you email so I have it again. I would like to ask you a question. BTW, the patent on my puzzle was finally allowed last month.
