On Jan. 4, the Patent Office released the long-awaited 2019 Revised Patent Subject Matter Eligibility Guidance, which governs the Office’s examination procedure for evaluation of patent subject matter eligibility under 35 U.S.C. § 101.
The new guidance distinctly changes the tone of § 101 discourse to one more in favor of eligibility than in years past. In the same way that the tone of prior Office guidance in the wake of Alice v. CLS Bank appeared to lean in favor of findings of ineligibility, despite a lack of concrete legal standards compelling this result, the more pro-patent feel of the new guidance will likely by itself lead to an uptick in allowance rates. Tone aside, however, beyond signaling an increase in the perceived permissibility of examiners finding patents eligible, there appears to be little additional substance in the new guidance that could be used to compel a skeptical examiner to find a given claimed invention to be patent-eligible.
