Has the importance of paper type for patent applications changed with digital record-keeping?
Yes, the importance of paper type for patent applications has diminished due to digital record-keeping practices at the USPTO. According to MPEP 714.07:
Because application papers are now maintained in an Image File Wrapper, the type of paper is unlikely to be an issue so long as the Office is able to scan and reproduce the papers that were filed.
This means that while the requirement for permanent dark ink still stands, the specific type of paper used is less critical as long as it can be properly scanned and digitized. However, applicants should still ensure that their documents are clearly legible and can be accurately reproduced in digital format.
