In the past, Musk has spoken out against the use of patents, explaining that the company avoids them.
Musk told CNBC that using patents in manufacturing is a sign of weakness.
Musk took Leno on a tour of the Star base facility in Texas, showing him some of the company's Raptor engines, which are designed to fit the spaceship. The engines were made in California.
The billionaire has been critical of the use of patents before. He said in an interview that the company has no patents. He said publishing the company's patents would be "farcical" because the Chinese would use them as recipe books.
Patents were a sign that a company was failing to innovate fast enough, according to Musk in a conference call eight years ago.
In an interview with CNBC, Musk stated that the rocket was made from strong steel. Musk said no when asked if the company had a patent for the material.
He told the outlet that the company doesn't patent anything. The patents are for the weak.
In the interview, Musk said that patents were usually used to block other companies from progressing. He told Leno that they stopped other people from following him. The majority of patents are bs.
His comments about patents come at a time when the company is close to launching its huge spaceship. The vehicle would probably launch in November, according to Musk.
