Exhibit 99.1

iBio, Inc. Initiates Litigation Against Fraunhofer-Gesellschaft in Delaware Chancery Court

New York, NY--(November 6, 2017) - iBio, Inc. (NYSE AMERICAN: IBIO), a leading provider of plant-based biotechnology for developing and manufacturing biological products, announced today that it initiated litigation against Fraunhofer-Gesellschaft (Fraunhofer) by filing a complaint in the Court of Chancery of the State of Delaware to remedy the consequences of Fraunhofer’s fraud and theft of iBio’s technology and intellectual property. This complaint follows iBio’s pending litigation filed in March 2015 against Fraunhofer USA, Inc., the U.S. unit of Fraunhofer.

After having engaged units of Fraunhofer for more than a decade to create a commercially viable plant-based method to manufacture biopharmaceuticals exclusively for iBio, iBio learned that Fraunhofer had fraudulently and in willful breach of the parties’ agreements secretly been offering iBio’s proprietary technology to third parties and otherwise exploiting it for Fraunhofer’s own benefit. Meanwhile, Fraunhofer was failing or refusing to perform required technology transfer to iBio of the technology it created exclusively for iBio’s ownership and use. The relief sought by iBio for damages against Fraunhofer, including the U.S. unit, now exceeds $200 million.

Reed Oslan of Kirkland & Ellis LLP will be heading up iBio’s litigation team along with lawyers at Morris, Nichols, Arsht, and Tunnell LLP.
