How should ‘Large Tables’ be submitted in patent applications?

‘Large Tables’ can be submitted in two ways:

1. Via the USPTO patent electronic filing system as ASCII plain text files
2. On read-only optical discs in compliance with 37 CFR 1.52(e)

According to 37 CFR 1.58(d), these ASCII plain text files must:

• Maintain spatial relationships of table elements
• Be compatible with PC or Mac computers and various operating systems
• Contain only ASCII characters with specific line terminator requirements
• Be named with a .txt extension
• Be incorporated by reference in the specification

There’s a 25 MB size limit for files submitted via the USPTO patent electronic filing system, with no compression allowed.
