How does the USPTO handle hazardous or dangerous materials submitted as exhibits?

The USPTO has specific procedures for handling hazardous or dangerous materials submitted as exhibits:

• Such materials are not accepted for retention by the Office.
• The Office will immediately dispose of these materials upon discovery.
• Applicants are advised against submitting hazardous or dangerous materials.

According to MPEP 608.03(a): No substances or materials considered hazardous or dangerous to Office personnel, will be accepted.

If an applicant needs to demonstrate properties of hazardous materials, they should consider alternative methods, such as detailed descriptions, simulations, or non-hazardous substitutes.
