As my prior post on the 2019 Revised Patent Subject Matter Eligibility Guidance indicated, I initially anticipated only a modest uptick in allowability rates as a result of the new guidance.  After analyzing the accompanying examples, however, I concluded that the effect would likely be markedly more profound.  Subsequent conversations with examiners—many of whom have now agreed to drop their long-standing eligibility rejections—have only confirmed that belief. The examples provide analyses of 10 claims…

[This post was updated on Jan. 17, 2019] 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.

Specifically: The overall percentage of decisions invalidating patents under § 101 since we started tracking statistics in July 2014 has fallen slightly—from 67.5% to 66.0%—year over year. The 12-month and three-month average invalidation rates have likewise fallen (from 64.7% to 61.9%, and from 72.1% to 48.4%, respectively).…

In my own prosecution practice I’ve noted a recent uptick in the allowance rate of many examiners in the 36XX art units, with several examiners that had hitherto never allowed a single case allowing multiple cases during calendar year 2017.  This piqued my interest, and I decided to conduct a more robust statistical evaluation to see whether my personal experience would bear out more generally. Signs of Recovery My evaluation computed the aggregate allowance-to-abandonment ratio…
