Revamping Patent Review: The Impact of Proposed Legislation on Patent Holders
The realm of intellectual property law is witnessing a pivotal legislative development that could significantly alter the landscape of patent validity assessments. H.R. 4370, a bill recently introduced by Representatives Ken Buck (R-CO4) and Deborah Ross (D-NC2), seeks to reform the processes of the Patent Trial and Appeal Board (PTAB) at the U.S. Patent and Trademark Office (PTO).
One of the bill's most critical aspects is the proposal to heighten the evidentiary standard required to invalidate a patent. This change could be a game-changer for patent holders who have long navigated the complexities of patent law.
The Current Landscape: PTAB vs. Federal Courts
In federal district court infringement lawsuits, a defendant may argue that the patent they allegedly infringed is invalid - a claim that the PTO should not have granted the patent initially. As established in the Supreme Court case Microsoft Corp. v. i4i Ltd. P’ship, to invalidate a patent, the challenger must provide "clear and convincing" evidence. This standard, though less stringent than the "beyond a reasonable doubt" criterion in criminal cases, still sets a high bar, presuming the patent's validity unless proven otherwise.
Conversely, the PTAB operates under a more lenient standard - the "preponderance of evidence." This standard means that if the evidence suggests it’s more likely than not that the patent should not have been granted, the PTAB can invalidate it. This lower threshold has made the PTAB a less favorable venue for patent holders. The statistics speak volumes: between October 2022 and June 2023, the PTAB reviewed 902 patents, and in 35% of these cases, at least one patent claim was invalidated.
The Proposed Change: A New Era for Patent Holders?
H.R. 4370, Section 4(e), aims to align the PTAB's evidentiary standard with that of the federal courts, requiring "clear and convincing" evidence to invalidate a patent. This proposed alignment signifies a substantial bolstering of patent holders' rights. It would potentially reduce the risk of patent invalidation at the PTAB, providing a stronger shield for patent holders against challenges to their intellectual property.
Implications for Patent Holders and the Future of IP Law
If passed, this legislation could mark a significant shift in patent law, empowering patent holders and potentially altering the dynamics of patent litigation. It could lead to a decrease in the number of patents invalidated by the PTAB, thereby strengthening the hand of patent holders in enforcement actions.
This legislative initiative could redefine the battleground for patent validity, emphasizing the importance of robust evidence and enhancing the integrity of patent rights.
