Word Games At The PTAB, PTAB Litigation Blog
In 2016, the PTAB changed the limits for the length of certain filings in post grant proceedings, including petitions and responses, from limits based on the number of pages to limits based on the number of words. The USPTO stated that this change was intended to improve efficiency within the office. As a practical matter, however, it was also likely intended to minimize the formatting games that parties had often used to make an otherwise too-long submission fit within the page limits. While the change may have been effective in that regard, some parties still attempt to improperly game the system.
