USPTO’s Withdrawal of 2022 Memo Alters PTAB Review Process

The U.S. Patent and Trademark Office (USPTO) has made a significant move by withdrawing a 2022 memo that dictated the circumstances under which the Patent Trial and Appeal Board (PTAB) might deny review of patents involved in parallel litigation. This decision, announced last Friday, allows the PTAB broader discretion in such matters, potentially leading to an increase in review denials. According to various legal experts, the cancellation of the memo marks a notable shift in the review process. For more details on this development, visit the full article on Law360.
