Despite contrary statements in certain board decisions,[1] the patent office’s guidance to the examining corps has been consistent: facts are unnecessary when rejecting a claim under 35 U.S.C. § 101. Early on, the patent office’s July 2015 subject matter eligibility update responded to concerns about whether examiners were properly making out a prima facie case of ineligibility by stating that patent eligibility was a question of law, and that no facts were necessary to make out a prima facie case.[2] The MPEP has also been amended to reflect this view,[3] and the superfluity of facts to eligibility appears to be a foundational assumption for the application of section 101 during examination.[4]

However, in light of the Federal Circuit’s recent decision in Berkheimer v. HP, Inc., the end of fact-free subject matter eligibility determinations may be near. In Berkheimer, the claims at issue were found to be directed to an abstract idea, so the case turned on whether the claims included additional elements sufficient to transform the nature of the claim into a patent eligible application rather than a patent ineligible abstraction.[5] The district court found that there were no such additional elements, because what additional elements the claims did recite described “steps that employ only ‘well-understood, routine, and conventional’ computer functions … at a high level of generality.”[6] The patent owner disagreed, arguing that portions of the patent’s specification referring to various benefits provided by the invention contradicted the finding that the claims described well, understood, routine, and conventional activities.[7] The Federal Circuit then analyzed the claims and, because it found that some of them recited steps for providing the improvements described in the specification,[8] vacated the district court’s holding of ineligibility.[9] More important than the result though, was the reasoning. The Federal Circuit specifically explained that the allegations of improved results from the specification created an issue of fact,[10] and that “the district court erred in concluding that there are no underlying factual questions to the § 101 inquiry.”[11] It also stated explicitly that “whether a claim element or combination of elements is well-understood, routine and conventional to a skilled artisan in the relevant field is a question of fact” and that “[a]ny fact, such as this one, that is pertinent to the invalidity conclusion must be proven by clear and convincing evidence.”[12] – i.e., the exact opposite of the patent office’s position on the issue.

Before posting this article, I called the PTO’s office of patent legal administration to ask if they were aware of the Berkheimer case and if they intended to update their guidance in light of its holding. While I was told that they were aware of the case, the person I spoke to did not know if there were plans to issue updated guidance based on its reasoning, or (if such updated guidance was in the works) when such updated guidance might be issued. Accordingly, at least for the foreseeable future, it appears that the primary channel for Examiners to be made aware of the Berkheimer case may be through their interactions with patent prosecutors.[13] However, given the potential significance of treating eligibility as involving underlying questions of fact, it would seem highly inappropriate for the PTO not to react to Berkheimer. As a result, while they may not be saying anything about it now, this is an issue where they shouldn’t remain speechless for long.
