Detailed Summary

In a decision dated March 17, 2024, the Patent Trial and Appeal Board denied Phison Electronics Corporation's request for a post‑grant review of U.S. Patent No. 11,830,546, owned by Vervain, LLC. The Board concluded that Phison failed to meet the statutory burden of showing that it was more likely than not that any of the seven challenged claims were unpatentable. Challenges based on patent‑eligible subject matter, obviousness, written description, enablement, and indefiniteness were found insufficient, and no claim term required explicit construction. Although the Board considered discretionary denial under §§ 324(a) and 325(d), it ultimately denied the petition and did not institute a review.
