Decisions by the Supreme Court and the Federal Circuit over the past decade have wrestled with the question that 35 U.S.C. §101 was intended to answer: What is eligible for patent protection? The text of §101 says a patent can be granted for “any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof.” Though this text has changed very little since it was first written in 1793, the courts have established a number of judicially created exceptions, and exceptions to those exceptions. This has created a growing difficulty and uncertainty in applying §101 to modern technologies, especially those implemented by computer systems. 

Bob Dylan famously sang that “[y]ou don’t need a weatherman to know which way the wind blows,” and we don’t need a weatherman to tell us that the wind now blows differently at the United States Patent and Trademark Office (USPTO). On January 7, 2019, the USPTO released revised subject matter eligibility examination guidance (“Guidance”), foreshadowed by USPTO Director Iancu last fall. The Guidance is noteworthy both for raising the bar in examination procedure and, we think, for signaling the Office’s intent to rein-in the application of subject matter ineligibility analysis (“lest it swallow all of patent law” – Alice). We anticipate a reduction in subject matter eligibility rejections because the Guidance makes it more difficult for examiners to reject claims as being directed to unpatentable subject matter under 35 U.S.C. §101.   

Taking into account what constitutes a disclosure, we can see the following guiding principles and trends emerging:

The issue of public disclosure is a frequent concern for inventors looking to obtain patent protection. While it may often be safest to wait until at least a provisional patent application is filed before having any discussion regarding the invention with a third party, it is often not practical. Is the idea of waiting to discuss with a third party until a patent application is filed an overly cautious practice? Consideration of what actually constitutes a public disclosure and the factors that courts take into account illustrate that avoiding any and all discussion of the invention may not be necessary.

Summary: While the Leahy-Smith America Invents Act (AIA) brought sweeping changes to the United States patent system, including moving to a first-to-file system and implementing and modifying a number of post-grant proceeding options, one less heralded change is the expansion of the third party preissuance submission process, by which a third party can submit prior art references in a pending U.S. patent application for consideration by the examiner. The revised preissuance submission process is significantly more robust and accessible than its pre-AIA counterpart. Key features of the process such as low cost, anonymity, and preclusion from estoppels make it a potentially attractive tool for challenging pending applications. However, a third party’s participation in the patent prosecution process is still limited and the submitted references may even inadvertently strengthen any patent that issues from the application in which the submission is filed. Accordingly, third parties should carefully consider the limitations and risks associated with the process before filing a preissuance submission.
