Panch Pratikraman Sutra does not have a single, fixed author in the Jain tradition. In many modern editions it is printed as a work compiled by an institution rather than authored by one person.

• Some manuscripts/editions specify the Original Sutra Author as N/A and attribute the text to Sukrutnidhi Trust (Gujarati edition). ( jainqq.org)
• Other manuscript references credit Siddhachal Kalyan Bhuvan tatha Surat as the source/compilers, again indicating a collective compilation rather than a single author. ( jainqq.org)

In short: Panch Pratikraman Sutra is generally viewed as a ritual text compiled by Jain lay and institutional patrons (not a single author), with at least these two lines of attribution appearing in different editions.
