Short Summary
Shenzhen Root Technology Co., Ltd. successfully petitioned the PTAB to institute an IPR against Willow Blossom Holdco Limited's breast pump patent (11813381).

Detailed Summary
Shenzhen Root Technology Co., Ltd. successfully petitioned the PTAB to institute an Inter Partes Review (IPR) against Willow Blossom Holdco Limited regarding patent number 11813381, which covers breast pump systems. The Board determined that Petitioner established a reasonable likelihood that at least one claim is unpatentable based on numerous grounds of obviousness under 35 U.S.C. § 103. Key to the decision was the adoption of the Petitioner's definition for a person having ordinary skill in the art (a mechanical engineering background with experience in human breast pump equipment). The Board specifically agreed that combining Chang’s portable, in-bra wearable system with Fang’s elastic diaphragm technology renders independent Claim 1 obvious.
