By the late , VPL had licensed technologies like the PowerGlove to consumer markets, such as Toys, broadening VR's accessibility and fueling industry-wide adoption. However, high development costs for specialized hardware limited scalability.

Bankruptcy and Aftermath

By the early 1990s, VPL Research had accumulated substantial debts amid the high costs of pioneering hardware and software, coupled with a commercial market that was not yet mature enough to support widespread adoption. The company's financial strain intensified due to loans from Thompson CSF, which were collateralized against VPL's valuable patent portfolio, leading to a suit by the lender. On November 12, 1993, VPL filed for Chapter 11 protection in the U.S. Bankruptcy Court for the Northern District of (Case No. 93-51675), aiming to reorganize while shielding assets from immediate creditor actions. During the Chapter 11 proceedings, VPL sought to divest non-core assets to stabilize operations, culminating in the sale of its core —including patents for optical flex sensors, control systems, the "3D Swivel" , and ten pending applications—to CSF for $150,000. The bankruptcy court approved this transaction on February 16, 1994; in exchange, forgave approximately $2 million in prior loans but retained a claim on a $150,000 loan provided during the case. With its primary assets transferred, VPL converted to Chapter 7 later in 1994, leaving unsecured creditors with severely diminished recoveries—typically five cents on the dollar. For instance, co-founder Thomas Zimmerman, who was owed $212,000 for unpaid work and inventions, received only nominal compensation, while neither president Jean-Jacques Grimaud nor Alan Defrenne transitioned to roles at CSF. The bankruptcy marked the end of VPL Research as an operating entity, but its technological persisted through the transferred patents, which facilitated ongoing advancements in human-computer and immersive environments. In February 1998, acquired VPL's patent and related technical assets from Thompson CSF and Greenleaf Medical, integrating them into its own and graphics research initiatives.
