Detailed Summary

Evenflo Company, Inc. filed a petition for inter partes review of Baby Jogger, LLC’s U.S. Patent No. 11,577,771, which claims a convertible single‑ to‑double‑seat stroller. The petitioner contends that the patent lacks a valid pre‑2016 priority date and that the asserted claims are obvious in view of five prior‑art references: Rolicki, Gotting, Britax, Offord ’341, and Offord ’797. Three separate §103 grounds are presented, covering all fifteen claims (or the first five for the Offord references). The petition also adopts a specific construction for the term “handle portion.” The PTAB has not yet decided whether to institute the review.
