Court Dismissal Over Late Filing Warns Tech Firms of Strict Patent Deadlines

WISECODE Take

The U.S. Court of Appeals for the Federal Circuit's ruling in Guymon v. Squires on September 10, 2020, highlights a critical procedural risk that enterprises often overlook when seeking patent term adjustments. The plaintiff attempted to file via email on the last day of the 180-day statutory deadline, which was rejected under the Eastern District of Virginia's local rules, resulting in the loss of 802 days of patent term adjustment. This underscores that courts will not compromise on procedural rules, regardless of how strong the underlying technology is. For biotech and hardware developers, procedural errors are akin to being disqualified from an athletic competition for arriving late. Companies without U.S. patent litigation are unaffected. Intellectual Classic's Patent Portfolio Health Check helps enterprises audit overseas patent deadlines. We suggest: first, establish dual-warning systems for patent deadlines to avoid last-week filings; second, ensure local agents have practical experience with specific court filing rules. Victory in patent battles depends heavily on precise control of procedural rules.
