Finnegan Secures Decisive ITC Victory for Innoscience in Final Determination

FOR IMMEDIATE RELEASE
May 11, 2026

WASHINGTON, DC—Finnegan has secured a decisive victory for Innoscience, a global leader in gallium nitride (GaN) power devices, as the U.S. International Trade Commission (“ITC”) issued its Final Determination in Investigation No. 337‑TA‑1414, confirming that Innoscience’s current gallium nitride (GaN) power devices do not infringe Infineon’s patents and may continue to be imported and sold in the United States without restriction.

The Commission squarely rejected Infineon’s core litigation objectives, affirming that Innoscience’s redesigned products—now its commercial offerings—fall outside the scope of Infineon’s U.S. Patent No. 9,899,481. The ruling guarantees Innoscience’s continued, uninterrupted access to the U.S. market and conclusively ends Infineon’s attempt to use the ITC to disrupt Innoscience’s business.

The Commission also invalidated four additional claims of the ’481 patent, further dismantling Infineon’s case. Only two claims survived, and only as applied to legacy products that have been discontinued, rendering the ITC’s limited exclusion and cease‑and‑desist orders commercially irrelevant.

Infineon’s parallel effort under U.S. Patent No. 9,070,755 also collapsed entirely. The Commission previously declined to review the Administrative Law Judge’s finding of no infringement, and Infineon’s deadline to appeal has expired. That ruling is now final and unassailable.

“This Final Determination confirms what the Initial Determination already made clear—Innoscience’s success in the U.S. market is the result of independent innovation, not copying,” said Finnegan partner and lead counsel Lionel Lavenue. “Infineon brought a multi‑patent ITC case to block Innoscience’s growth. Every one of those efforts has now failed. This is a decisive win, end to end.”

Lionel added, “Just as importantly, the Commission validated Innoscience’s design‑around strategy. Innoscience protected its customers and preserved uninterrupted access to the U.S. market while this investigation was pending. That is exactly how the ITC process should work.”

Infineon filed its ITC complaint in 2024 seeking to exclude Innoscience from the U.S. market. “Finnegan responded with a coordinated, high‑pressure defense, defeating Infineon’s infringement theories, invalidating patent claims at the Commission, and executing a rapid design‑around strategy that preserved uninterrupted market access throughout the investigation,” said Finnegan partner Chen Zang, Ph.D.

“The ITC’s Final Determination leaves no ambiguity,” Lionel added, “Innoscience’s current products are non‑infringing, and Infineon’s exclusion campaign failed. Whatever momentum Infineon hoped to gain from this ITC action has now fully evaporated.

With more than 90 attorneys dedicated to ITC litigation, Finnegan is the undisputed leader in defending respondents facing high‑stakes Section 337 investigations and neutralizing attempts to weaponize trade law against legitimate competition.

The case is In the Matter of Certain Semiconductor Devices and Products Containing the Same, Investigation No. 337‑TA‑1414 (U.S. International Trade Commission).
