The PTAB recently released the second round of proposed changes to the AIA. Below is a segment of the USPTO's statement regarding the changes and a link to the article:
"In particular, the package of changes:
• Proposes to allow patent owners to include, with their opposition to a petition to institute a proceeding, new testimonial evidence such as expert declaration. This change responds to commentary raising concerns that patent owners are disadvantaged by current rules that let petitioners’ evidence go unanswered before a trial is instituted.
• Proposes a new requirement on practitioners before the PTAB, akin to the Rule 11 requirements in federal courts, to give the USPTO a more robust means with which to police misconduct.
