"Terminal disclaimers now appear on about 10% of issued utility patents, the lowest annual rate since 2008 and down from almost 22% in 2023. Obviousness-type double patenting (OTDP) may be the nerdiest of our patent doctrines - but I was surprised by the transformation in terminal disclaimer practice."
"The Federal Circuit meanwhile is set to decide how much of the doctrine survives. In re Ablynx N.V., No. 26-1333 (Fed. Cir.), asks whether an OTDP rejection can rest solely on the risk of harassment by multiple assignees, with no extension of patent term to justify it. Last month I wrote about the USPTO's answer to that question in Ex parte Baurin (Aug. 9, 2026), and then the appeal itself (Aug. 16, 2026). Further briefing in the case is due later this month (September 2026)."

"I first looked for a doctrinal explanation for the shift because there has been a lot of action with regard to OTDP and terminal disclaimers the past few years. See, for example, In re Cellect, 81 F.4th 1216 (Fed. Cir. 2023); and Allergan USA, Inc. v. MSN Laboratories Private Ltd., 111 F.4th 1358 (Fed. Cir. 2024)."
