How does the USPTO define “printed publication” for prior art purposes?

The USPTO’s definition of “printed publication” for prior art purposes is broad and evolving. According to MPEP 2128:

“The term “printed publication” refers to such publications as books, magazines, journals, microfilm, computer databases, and Internet publications.”

This definition is not limited to traditional printed materials but includes various forms of media that can disseminate information. The key factors are:

• The information must be accessible to the public
• The publication date must be determinable
• The content must be in a fixed form

It’s important to note that the format of the publication is less important than its accessibility and ability to disseminate information to the public.
